What Is a Biscuit Tin Making Machine
A biscuit tin making machine is a specialized production line that manufactures tinplate cans designed specifically for biscuit packaging. Unlike generic food can making machines that produce round cans for wet products (tuna, vegetables, soup), a biscuit tin making machine must accommodate three distinct requirements that define the biscuit packaging category:
- Extreme moisture barrier performance — Biscuits are hygroscopic products with a target moisture content of <3% (typically 1–2.5% for crisp-textured biscuits). The tin must maintain this moisture level over a shelf life of 6–18 months, requiring hermetic double-seam integrity with leakage ≤0.5 mL/min and, in many configurations, nitrogen-flushed headspace to displace residual oxygen and humidity.
- Decorative lithographic printing compatibility — Biscuit tins are among the most visually decorated metal packaging formats in the food industry. Unlike plain food cans that receive paper labels, biscuit tins carry full-color offset lithographic printing directly on the tinplate surface — often with 4–6 color stations, metallic inks, embossing, and spot varnish. The can-making process must not distort, scratch, or offset these printed surfaces during forming, welding, flanging, and seaming operations.
- Multi-shape versatility — Biscuit tins are produced in a wider variety of shapes than most other food packaging categories: rectangular/square tins (the dominant format for gift-pack biscuit assortments), round tins (for single-variety biscuits and family-size packs), and oval tins (for premium and seasonal lines). A biscuit tin making machine must accommodate tooling changes across these formats within practical changeover times.
Biscuit Tin vs. Generic Food Can: Why Dedicated Equipment Matters
| Parameter | Biscuit Tin | Generic Food Can (tuna/vegetables) |
|---|---|---|
| Moisture sensitivity | Critical (<3% biscuit MC) | Low (wet product, aw >0.85) |
| Shelf life target | 6–18 months (crispness retention) | 12–36 months (sterilized) |
| Decoration | Full-color litho print on tinplate | Paper label or plain |
| Typical shapes | Square, round, oval | Round only |
| Typical sizes | 150×100×80 mm (square), Ø80–120 mm (round) | Ø65–99 mm (round) |
| Typical capacity | 200–500 g (retail), 1–3 kg (gift) | 100–850 g |
| Material thickness | 0.16–0.25 mm (thinner for decoration) | 0.18–0.30 mm |
| Internal coating | BPA-NI 4–8 g/m² or food-grade epoxy | Epoxy phenolic 4–14 g/m² |
| Seam requirement | Hermetic moisture barrier (WVTR <0.5) | Hermetic for retort (pressure-rated) |
| Nitrogen flushing | Required for premium lines | Not typical |
| Print registration | ±0.3 mm (litho decoration) | N/A (paper label) |
| Retort compatibility | Not required (dry product) | Required (121°C, 30 min) |
| Stacking strength | Moderate (gift display) | High (palletized) |
The food can making machine covered in our earlier guide addresses wet-product requirements including retort sterilization. The biscuit tin making machine shares the same fundamental 3-piece can architecture but diverges significantly in moisture management, decoration handling, and shape flexibility.
Biscuit Tin Types, Sizes & Industry Standards
Standard Biscuit Tin Dimensions
Biscuit tins cover a range of sizes designed for different market segments — from single-serve mini tins to large gift assortments:
| Tin Type | Dimensions (mm) | Capacity (g) | Typical Use | Shape |
|---|---|---|---|---|
| Mini round | Ø80 × 60 | 100–150 | Single-serve, promotional | Round |
| Small round | Ø100 × 75 | 200–300 | Retail standard | Round |
| Medium round | Ø120 × 100 | 350–500 | Family size | Round |
| Small rectangular | 150 × 100 × 80 | 200–300 | Gift box entry | Square/Rect |
| Medium rectangular | 200 × 150 × 100 | 400–600 | Gift assortment | Square/Rect |
| Large rectangular | 250 × 180 × 120 | 800–1500 | Premium gift tin | Square/Rect |
| Oval tin | 160 × 100 × 80 | 250–400 | Seasonal/specialty | Oval |
| Large oval | 220 × 140 × 100 | 500–800 | Premium seasonal | Oval |
International Standards Applicable to Biscuit Tin Manufacturing
| Standard | Scope | Key Requirement for Biscuit Tins |
|---|---|---|
| ISO 22000:2018 | Food safety management | HACCP-based hazard analysis for packaging materials in contact with food |
| ISO 11140 | Metal packaging — Materials | Tinplate and TFS specification for food contact |
| EN 10202 | Cold-reduced electrolytic tinplate | ETP coating masses #25–#50 g/m² for biscuit tins |
| JIS G 3303 | Tinplate and TFS (Japanese) | Alternative substrate spec for Asian market biscuit tins |
| ASTM A623/A624 | Tinplate (US) | Substrate specification for North American biscuit tin production |
| FDA 21 CFR 175.300 | Internal coatings | BPA-NI and epoxy coating limits for food-contact surfaces |
| EU Regulation 1935:2004 | Food-contact materials | Overall migration limit <10 mg/dm² for coating systems |
| EU Regulation 2018:213 | BPA restriction | BPA migration limit 0.05 mg/kg for food-contact coatings |
| GB 4806.10-2016 | Food-contact metal (China) | Chinese national standard for metal food packaging materials |
| ISO 9001:2015 | Quality management | Manufacturing process certification (Yongxin Cert. No. 107325Q1009R0S) |
Substrate Options for Biscuit Tins
| Substrate | Coating Spec | Thickness (mm) | Print Quality | Corrosion Resistance | Cost (USD/tonne) | Biscuit Tin Preference |
|---|---|---|---|---|---|---|
| ETP (Electrolytic Tinplate) | #25–#50 g/m² Sn | 0.16–0.25 | Excellent (smooth, bright) | Good | 850–1,200 | Primary choice (70%+ of biscuit tins) |
| TFS (Tin-Free Steel / Cr-coated) | Cr 50–200 mg/m² | 0.16–0.25 | Very good (requires primer) | Moderate | 750–1,050 | Budget lines, internal-only tins |
| SPCC + Sn coating (hot-dip) | 2–8 g/m² Sn | 0.18–0.28 | Acceptable (rougher surface) | Moderate | 700–950 | Low-decor economy tins |
For biscuit tins requiring high-quality lithographic decoration, ETP (Electrolytic Tinplate) with a bright or stone finish at #25–#50 coating mass is the dominant substrate. The smooth, uniform tin surface provides the necessary ink-adhesion base for 4–6 color offset lithography with registration accuracy of ±0.3 mm.
Key Process Requirements Unique to Biscuit Tin Production
Biscuit tin manufacturing involves several process requirements that distinguish it from standard food can production. Each requirement reflects the specific demands of preserving biscuit quality and presenting premium decorative packaging.
1. Extreme Moisture Barrier — Hermetic Sealing for Crispness Retention
Biscuits are among the most moisture-sensitive food products. The target moisture content for most commercial biscuits is 1–3%:
- Soft-dough biscuits (cookies): 2–3% moisture
- Crisp crackers: 1–2% moisture
- Shortbread: 1.5–2.5% moisture
- Wafer biscuits: 1–1.5% moisture
When biscuit moisture rises above 4–5%, the product loses crispness, becomes stale, and eventually develops mold. The tin packaging must therefore maintain a moisture vapor transmission rate (WVTR) of <0.5 g/m²/day — effectively a near-total barrier.
Process implementation:
The hermetic moisture barrier is achieved through three combined measures:
- Double-seam integrity: Yongxin’s 8-cam 8-roller synchronous seaming head produces a 5-layer double seam with thickness 1.15–1.35 mm, hook length 1.8–2.2 mm, and body hook blend (BHB) ≥45%. These parameters exceed the minimum for hermetic sealing — leakage rate ≤0.5 mL/min when tested by pressure decay method.
- Internal coating continuity: BPA-NI (Bisphenol-A Non-Intent) coating at 4–8 g/m² is applied to all internal surfaces. The coating must be continuous — without pinholes, scratches, or thin spots — as any break in the coating creates a moisture pathway. Curing at 180–200°C for 40–55 seconds ensures cross-linking and chemical resistance.
- Nitrogen flushing (premium lines): For premium biscuit tins, the headspace is flushed with nitrogen (N₂) to displace oxygen and residual humidity before lid seaming. Target residual O₂ <1–2% in headspace. This dual-purpose treatment inhibits oxidative rancidity (biscuits contain 10–25% fat) and eliminates moisture-bearing air from the sealed environment.
2. Decorative Lithographic Printing Integration
Biscuit tins are distinguished from other food cans by their extensive decoration. A premium biscuit gift tin may feature:
- 4–6 color offset lithographic printing covering 100% of the exterior surface
- Metallic gold/silver ink accents
- Embossed textures (raised patterns, brand logos)
- Spot varnish or gloss/matte contrast finishes
- Wrap-around decoration with pattern continuity across seams
Impact on can-making process:
The lithographic printing stage is integrated into the biscuit tin production line between body forming and final assembly. The decoration workflow:
- Pre-print surface preparation: Tinplate sheets are cleaned and treated for ink adhesion before printing
- Base coat application: A white or colored base coat is applied and UV-cured
- Multi-color lithographic printing: 4–6 color stations apply CMYK + spot colors (Pantone matching) with registration accuracy of ±0.3 mm
- Varnish overcoat: Protective varnish is applied over the printed image
- Curing: UV or thermal curing at 150–180°C for 10–15 minutes
The can-making equipment must handle pre-printed sheets without marring the surface. This requires:
- Non-contact transport: Air-cushion or vacuum-belt conveyors at critical stages
- Protected forming dies: Polished, chrome-plated forming tools that do not scratch printed surfaces
- Controlled bending radii: Minimum bend radii that prevent ink cracking on tight corners (especially important for square biscuit tins)
- Weld zone management: The side-seam welding area (typically 10–15 mm strip) is left unprinted; the welding process must not cause heat distortion that propagates into the printed zone
For square biscuit tins, the corner-pressing operation requires particular care. The corner radius (typically R3–R8 mm) represents the point of highest stress on the lithographic coating. Yongxin’s corner-pressing modules use independent electro-mechanical stops and precision die-sets that maintain corner radius consistency within ±0.2 mm — preventing ink cracking or delamination at the corners.
3. Multi-Shape Production — Square, Round, and Oval
Biscuit tins are produced in more shape variations than most other food packaging formats:
| Shape | Market Share (est.) | Tooling Complexity | Changeover Time |
|---|---|---|---|
| Square/Rectangular | 55–60% | High (corner-pressing, rectangular flanging) | 15–30 min (with servo-driven tooling change) |
| Round | 30–35% | Standard (rounding, standard flanging) | 5–10 min |
| Oval | 5–10% | High (oval forming dies, special flanging) | 20–40 min |
The dominance of square/rectangular biscuit tins reflects the gift-packaging segment, where rectangular tins accommodate nested biscuit varieties in compartmentalized inserts. Round biscuit tins serve the retail single-variety segment (e.g., shortbread rounds, digestives). Oval tins occupy a niche in premium/seasonal lines.
Yongxin’s multi-shape capability:
Yongxin’s production lines support multi-shape production through modular tooling systems:
- Small Square Can Line (30–35 CPM): Base platform for 1–5L rectangular/square biscuit tins (diagonal 45–280 mm, height 90–350 mm). Tooling change for format switching completes within 5 minutes via servo-driven electronic adjustment.
- Small Round Can Line (30–40 CPM): Handles Ø60–180 mm round biscuit tins (height 66–330 mm).
- Small Square Fast Line (45–60 CPM): Higher-speed variant for production runs of standard square biscuit tin formats.
- Small Round High-Speed Line (60–80 CPM): For high-volume round biscuit tin programs.
For biscuit manufacturers producing both square and round formats, the recommended approach is a dual-line configuration with shared slitting, welding, and end-making infrastructure.
4. Food-Grade Internal Coating — Odor-Free, Migration-Compliant
Biscuit tins require internal coatings that meet two critical criteria:
- Moisture barrier function: The coating must provide a continuous, pinhole-free barrier against water vapor transmission. Target WVTR <0.5 g/m²/day.
- Odor-free / migration-compliant: Biscuits readily absorb volatile organic compounds (VOCs) from their environment — a phenomenon known as “taint uptake” or “odor absorption.” The internal coating must not release any detectable odor or taste that could transfer to the biscuit product. This is verified through:
- Sensory panel testing (triangle test, threshold test)
- Gas Chromatography–Mass Spectrometry (GC-MS) for volatile compound identification
- Overall migration testing per EU 1935:2004 (<10 mg/dm²)
Coating chemistry options for biscuit tins:
| Coating Type | Application Temp (°C) | Cure Temp (°C) | Weight (g/m²) | Odor Performance | Cost |
|---|---|---|---|---|---|
| BPA-NI (Non-Intent) | 180–200 | 180–200 | 4–8 | Excellent (low VOC) | Medium |
| Epoxy phenolic | 180–210 | 180–210 | 6–14 | Good (requires post-bake degassing) | Low–Medium |
| Polyester | 200–220 | 200–220 | 6–12 | Very good | Medium |
| Vinyl organosol | 180–200 | 180–200 | 8–16 | Excellent | High |
For premium biscuit tins, BPA-NI (Bisphenol-A Non-Intent) coating at 4–8 g/m² is the standard choice. It provides the dual benefit of EU 2018:213 BPA compliance (migration <0.05 mg/kg) and low-odor performance verified by sensory panel.

| High-speed | 200–600 | 50–100 | 55–160 | 25 | 5,300 |
The high-speed sealer at 200–600 CPM is suitable for dedicated round biscuit tin programs (Ø50–100 mm diameter range covers the standard Ø80–120 mm biscuit tin formats), integrated directly into the biscuit filling facility.
13-Station Biscuit Tin Production Process Flow
The complete biscuit tin production flow comprises 13 stations, including 3 stations specific to biscuit tin requirements:
| Station | Operation | Biscuit Tin Specific? |
|---|---|---|
| 1 | Sheet feeding & storage | No |
| 2 | Slitting & sheet cutting (to body blank + lid blank) | No |
| 3 | Body forming (rounding for round; corner-pressing for square) | Square only: corner-pressing precision |

| 9 | Internal coating spray (BPA-NI, 4–8 g/m²) + curing | YES — moisture barrier coating |
| 10 | Flanging (internal-external dual-groove) | No (but dual-groove critical for seam integrity) |
| 11 | Beading (structural ribs for square tins) | Square: 2–4 ribs per face, 3–5 mm height |
| 12 | Curling (lid preparation) | No |
| 13 | Seaming (8-cam 8-roller synchronous head + CN118025556B lid feeder) + N₂ flushing + leak test | YES — N₂ flush for premium biscuit tins |
Stations 8, 9, and 13 represent the three biscuit tin-specific process stages that distinguish this line from a standard food can line.
Yongxin’s 3 Signature Technologies Applied to Biscuit Tin Production
1. 8-Cam 8-Roller Synchronous Seaming Head
The seaming head is the heart of the biscuit tin production line. Yongxin’s 8-cam 8-roller synchronous seaming mechanism delivers:
- Seam thickness: 1.15–1.35 mm (5-layer double seam)
- Hook length: 1.8–2.2 mm (body hook and cover hook)
- Body Hook Blend (BHB): ≥45%
- Seaming consistency: ±0.05 mm across all 8 stations
- Leak rate: ≤0.5 mL/min (pressure decay test)
For biscuit tins, the hermetic seam is the primary moisture barrier. Even a 0.1 mm gap in the double seam creates a pathway for ambient humidity to reach the biscuits. The 8-cam architecture ensures uniform pressure distribution around the entire seam circumference — critical for square biscuit tins where corner apex zones experience higher stress concentrations during seaming.
2. Internal-External Dual-Groove Flanging Wheel
Yongxin’s flanging system uses a dual-groove wheel configuration with precision bearings in a composite structure. This design provides:
- Fatigue resistance 2–3× longer than single-groove conventional flanging wheels (critical for high-volume biscuit tin runs)
- Consistent flange geometry across the full production run — preventing flange waviness that would compromise the double-seam integrity
- Reduced tooling change time: Groove profile changes for different tin sizes are accomplished by swapping the grooved wheel unit, not the entire flanging head
For square biscuit tins, the rectangular flanging operation requires an internal-external dual-groove wheel that tracks the rectangular perimeter with constant tool pressure. The linear-guide flanging template (a Yongxin design) reduces friction and maintains consistent flange depth at corners and flat sections alike.
3. CN118025556B — Synchronous Continuous Lid Feeding Mechanism
Patented in May 2026 (CN118025556B), this mechanism provides:
- Lid positioning accuracy: ±0.1 mm
- Continuous feed without stoppage: Eliminates the intermittent start-stop cycle of conventional lid feeders
- Compatibility with N₂ flushing: The synchronous timing allows nitrogen injection between lid placement and seaming — critical for premium biscuit tin lines
- Reduced lid damage: Smooth, non-impact transfer prevents denting or edge deformation of pre-printed biscuit tin lids
For decorated biscuit tin lids (which carry the brand image and decorative lithographic printing), the ±0.1 mm positioning accuracy ensures the lid’s printed design aligns correctly with the body’s decoration pattern when the tin is closed — maintaining visual continuity across the body-lid junction.
Welding Technology for Biscuit Tin Materials
Biscuit tins typically use thinner tinplate (0.16–0.25 mm) than standard food cans (0.18–0.30 mm), because thinner material provides better formability for tight-radius corners in square tins and superior surface quality for lithographic printing.
Welding Parameters for Biscuit Tin Thickness Range
| Parameter | Thin Gauge (0.16–0.20 mm) | Medium Gauge (0.20–0.25 mm) |
|---|---|---|
| Copper wire diameter (mm) | Ø1.35–1.50 | Ø1.35–1.50 |
| Welding current (KVA) | 18–40 | 18–40 |
| Overlap width (mm) | 0.8–1.0 | 0.8–1.2 |
| Weld speed (can/min) | 20–40 | 20–40 |
| Wire consumption | Standard | Standard |
Four-Layer Welding Quality Verification
Every welded biscuit tin body passes four quality verification steps:
- Visual inspection: Weld continuity, no burn-through, no spatter
- Tensile test: Weld strength ≥ base material strength (sample every 200 cans)
- Flattening test: Weld zone flattened to 2 mm gap without cracking
- Metallographic cross-section: Periodic (every 2,000 cans) — verifies fusion zone depth, heat-affected zone width, and copper wire penetration
For biscuit tins, the welding zone receives internal stripe touch-up (Station 6) where a food-grade coating is applied over the exposed weld on the interior surface, maintaining the moisture barrier continuity across the weld line.
Quality Control Framework — Five-Stage ISO 9001 Certified System

FAQ: Biscuit Tin Making Machine
Q1: What is a biscuit tin making machine?
A: A biscuit tin making machine is a production line that manufactures tinplate cans for biscuit packaging. It differs from standard food can lines in three ways: (1) hermetic moisture barrier sealing to maintain biscuit crispness (<3% moisture content), (2) compatibility with full-color lithographic decoration printing, and (3) multi-shape capability for square, round, and oval biscuit tin formats. Yongxin's biscuit tin lines operate at 30–80 CPM depending on configuration.
Q2: What shapes of biscuit tins can Yongxin’s machines produce?
A: Yongxin’s small square can lines (30–35 CPM and 45–60 CPM) produce rectangular/square biscuit tins with diagonal range 45–280 mm and height 90–350 mm. The small round can lines (30–40 CPM and 60–80 CPM) produce round biscuit tins with Ø60–180 mm diameter range. Oval biscuit tins can be produced using specialized oval-forming tooling kits fitted to the square can line platform. For biscuit manufacturers requiring both square and round formats, a dual-line configuration with shared infrastructure is recommended.
Q3: How does the moisture barrier requirement affect biscuit tin production?
A: Biscuits require moisture content below 3% for crispness and shelf stability. The tin must prevent moisture ingress over a 6–18 month shelf life. This requires: (1) hermetic double-seam integrity with leakage ≤0.5 mL/min, achieved by Yongxin’s 8-cam 8-roller seaming head at 1.15–1.35 mm seam thickness; (2) continuous internal BPA-NI coating at 4–8 g/m² verified by high-voltage pinhole detection; and (3) nitrogen flushing (premium lines) to reduce headspace O₂ below 1–2% and eliminate moisture-bearing air.
Q4: Can lithographic decoration printing be integrated into the production line?
A: Yes. The lithographic decoration station is integrated between body forming and final seaming (Station 8 in the 13-station process flow). It includes base coat application, 4–6 color offset lithographic printing with ±0.3 mm registration, and UV/thermal varnish overcoat. The equipment is designed to handle pre-printed sheets through non-contact transport systems and protected forming tools that prevent surface damage. Yongxin can supply the decoration station as an integrated line module or as a standalone add-on unit.
Q5: What is the production capacity of a biscuit tin making line?
A: Capacity depends on line configuration:
- Small Round 30–40 CPM: ~16–22 million tins/year (single shift, 300 days, 75% OEE)
- Small Round 60–80 CPM: ~32–43 million tins/year
- Small Square 30–35 CPM: ~14–18 million tins/year
- Small Square Fast 45–60 CPM: ~22–30 million tins/year
For dual-shape operations (square + round), total output is the sum of both lines operating independently.
Q6: What is the price range for a biscuit tin making machine?
A: FOB price ranges (Shanghai/Ningbo):
- Small Round 30–40 CPM base line: USD 80,000–130,000
- Small Square 30–35 CPM line: USD 100,000–160,000
- Small Square Fast 45–60 CPM line: USD 180,000–280,000
- Decoration station add-on: USD 40,000–80,000
- N₂ flushing module: USD 15,000–30,000
- High-speed sealer (200–600 CPM): USD 80,000–150,000

A: Yes. Yongxin provides:
- 48-hour on-site installation & commissioning (domestic China)
- 7–21 days on-site commissioning (international)
- 3–5 days operator training (mechanical operation, safety procedures, quality inspection)
- 3–5 days maintenance training (preventive maintenance, spare parts, troubleshooting)
- Lifetime technical support via remote VPN connection
- 12-month warranty from commissioning date
- Spare parts delivery within 3–7 days by air express
Q9: What certifications does Yongxin hold for biscuit tin equipment export?
A: Yongxin holds:
- National High-Tech Enterprise (GR202536000972)
- ISO 9001:2015 Quality Management System (Cert. No. 107325Q1009R0S)

- 86 patents + 6 software copyrights
All equipment is manufactured to ISO standards and can be configured to meet FDA 21 CFR, EU 1935:2004, and GB 4806 food-contact requirements.
Q10: Can Yongxin’s biscuit tin lines handle both square and round tins?
A: Individual lines are optimized for either square or round production. For biscuit manufacturers requiring both shapes, Yongxin recommends a dual-line configuration: one Small Square line (30–35 CPM) + one Small Round line (30–40 CPM) with shared slitting, welding, and end-making infrastructure. This approach provides dedicated optimization for each shape while minimizing total capital investment through shared auxiliary equipment. The electronic tooling change system on the small square line allows format switching within 5 minutes via servo-driven adjustment.
Q11: What material thickness is suitable for biscuit tins?
A: Biscuit tins typically use ETP (electrolytic tinplate) at 0.16–0.25 mm thickness. The thinner gauge (compared to food cans at 0.18–0.30 mm) provides better formability for tight-radius corners in square tins and superior surface smoothness for lithographic printing. All of Yongxin’s small can lines support 0.16–0.4 mm material range, fully covering the biscuit tin specification.
Q12: How does a biscuit tin line compare to a food can line in terms of investment?
A: A biscuit tin line typically requires lower capital investment than a food can line because: (1) no retort sterilization equipment is needed (biscuits are dry products), (2) the line speed is moderate (30–60 CPM vs. 80+ CPM for high-speed food can lines), and (3) the primary additional investment is the decoration station (USD 40–80k). Entry-level biscuit tin lines start at USD 120,000 (compared to USD 200,000+ for a food can line with retort capability).
