Yongxin’s juice can making machine configurations address the four unique process demands of juice packaging — hermetic seal integrity with oxygen ingress below 50 ppb, full light opacity to protect vitamin C from photo-oxidation, acid-resistant BPA-NI internal coatings for fruit acids at pH 3.0–4.5, and pasteurization compatibility at 72 °C / 15 s or UHT 135 °C / 2–5 s — while delivering 30–80 CPM throughput on automatic round can production lines engineered since 2005.
1. What Is a Juice Can Making Machine?
A juice can making machine is a production line or set of individual machines that converts flat tinplate or TFS (tin-free steel) sheets into finished three-piece cylindrical cans specifically designed for juice filling, sealing, pasteurization, and distribution. Unlike generic beverage can lines or food can lines, a juice can making machine must accommodate the distinct chemical and biological properties of fruit juice — high acidity (pH 3.0–4.5 for orange, apple, and tropical juices), sensitivity to dissolved oxygen (O₂ causes rapid vitamin C degradation and browning), sensitivity to light (UV 350–500 nm accelerates photo-oxidation of carotenoids and ascorbic acid), and thermal processing requirements (pasteurization at 72 °C for 15 seconds or UHT at 135 °C for 2–5 seconds).
Jiujiang Yongxin Can Equipment Co., Ltd. (九江市永信制罐设备有限公司), founded in 2005 and headquartered at No. 005 Antai Road, Jiujiang, Jiangxi, China (GPS: 29.6782°N, 115.9234°E), manufactures juice can making machine configurations built around two core production lines:
- Small Round Can Production Line (Standard): 30–40 CPM, 8 kW, 2,700 kg, Ø60–180 mm cans, 5,400 × 1,200 × 1,900 mm footprint
- Small Round Can High-Speed Production Line: 60–80 CPM, 12 kW, 5,300 kg, Ø60–180 mm cans, 7,600 × 1,200 × 1,900 mm footprint
Both lines are complemented by the Food Can Sealing Machine series (semi-auto 60–80 CPM, auto 40–60 CPM, high-speed 200–600 CPM) for dedicated end-seaming operations.
Juice Can vs Beverage Can vs Beer Can vs Food Can — What Differs?
| Parameter | Juice Can | Beverage Can (general) | Beer Can | Food Can |
|---|---|---|---|---|
| Primary concern | O₂ barrier < 50 ppb + vitamin C light protection | Carbonation retention + shelf appeal | CO₂ pressure 2.5–3.0 bar + light opacity | Retort 121 °C + F₀ ≥ 3.0–10.0 |
| Internal pH | 3.0–4.5 (acidic fruit) | 2.5–4.0 (carbonic + citric) | 4.0–4.5 (near-neutral) | 3.5–7.0 (varies widely) |
| Pasteurization | 72 °C / 15 s or UHT 135 °C / 2–5 s | Not required (ambient fill) | Not required (cold fill / sterile) | 121 °C / 15–30 min (retort) |
| Light requirement | Full opacity (UV 350–500 nm vitamin C protection) | Partial opacity (brand dependent) | 100 % opacity (MBT prevention) | Not critical (shelf-stable) |
| Coating type | Acid-resistant BPA-NI 4–8 g/m² | Standard BPA-NI or epoxy | Alcohol-resistant BPA-NI 4–8 g/m² | Epoxy phenolic 4–14 g/m² |
| Typical O₂ spec | < 50 ppb dissolved O₂ | < 50 ppb (similar) | < 50 ppb (similar) | Residual O₂ < 2 % (N₂ flush) |
| Typical can size | Ø66 × 115 mm (330 ml), Ø66 × 165 mm (500 ml), Ø73 × 120 mm (355 ml) | Ø66 × 115 mm (330 ml) standard | Ø66 × 115 mm (330 ml), Ø66 × 165 mm (500 ml) | Ø65–99 mm (307/401/603 series) |
| Seam thickness | 1.15–1.35 mm, BHB ≥ 45 % | 1.15–1.35 mm | 1.15–1.35 mm, rated 5.0 bar burst | 1.15–1.35 mm, retort-rated |
This differentiation is critical: while beverage can lines (covered in our beverage can making machine guide) share some overlap with juice can lines in seam integrity and O₂ barrier, juice cans add two unique requirements — acid-resistant internal coatings and light opacity for vitamin C preservation — that generic beverage lines may not address.
2. Juice Can Types, Sizes & Industry Standards

3. Key Process Requirements Unique to Juice Cans
Juice cans have four process requirements that distinguish them from generic beverage, beer, or food cans. Each requirement directly addresses the chemical and biological characteristics of fruit juice.
3.1 Hermetic Seal Integrity — O₂ Ingress < 50 ppb
Fruit juice is highly sensitive to dissolved oxygen. When O₂ permeates through the can seam or pinholes, it triggers:
- Vitamin C (ascorbic acid) oxidation: Each 1 % increase in headspace O₂ reduces vitamin C content by 3–5 % over 6 months shelf life
- Enzymatic browning: Polyphenol oxidase (PPO) activity increases with O₂, darkening the juice
- Flavor degradation: Oxidation of terpenes and esters produces off-flavours (cardboard, metallic notes)
Yongxin’s 8-cam 8-roller synchronous seaming head produces a 5-layer double seam with:
- Seam thickness: 1.15–1.35 mm (consistent ± 0.05 mm tolerance across all production)
- Body hook / cover hook: 1.8–2.2 mm each
- BHB (Body Hook Balance): ≥ 45 %
- Tightness rating: Hermetic to O₂ ingress < 50 ppb when combined with N₂ headspace flushing
The seam structure forms a mechanical barrier equivalent to a weld in gas-tightness, verified by destructive cross-section analysis per ISO 11140 protocols.
3.2 Light Opacity — Full UV Blocking 350–500 nm
Vitamin C (ascorbic acid) and carotenoids in juice are photo-sensitive. UV light at wavelengths 350–500 nm accelerates photo-oxidation through:
- Riboflavin sensitization: Riboflavin (vitamin B₂) acts as a photosensitizer, generating singlet oxygen that attacks ascorbic acid
- Carotenoid bleaching: β-carotene and lycopene lose color and nutritional value under UV exposure
- Off-flavor formation: Light-struck juice develops “sunlight” off-flavours similar to skunky beer (though juice lacks humulones, different photo-reactions produce analogous compounds)
Juice cans address this through:
- Opaque tinplate substrate: Bare tinplate provides 100 % light opacity — no light transmission
- External opaque coating: White or colored opaque overprint varnish adds a secondary light barrier
- Internal light-blocking layer: For premium juices, an additional TiO₂-loaded coating blocks residual transmission at seam overlaps
High-voltage pinhole testing at 15–25 kV verifies coating continuity across the entire can surface, ensuring no microscopic pinholes compromise light protection.
3.3 Acid-Resistant Internal Coating — BPA-NI at 4–8 g/m²
Fruit juices contain citric acid (orange, lemon), malic acid (apple), and tartaric acid (grape) at pH 3.0–4.5. These acids attack bare tinplate, causing:
- Tin dissolution: Tin ions migrate into juice, producing metallic off-flavours at concentrations > 50 mg/kg
- Hydrogen swells: Acid-tin reactions generate hydrogen gas, causing can swelling and potential seam failure
- Iron exposure: Once tin is consumed, the underlying steel corrodes rapidly, leading to perforation
Yongxin juice can lines apply acid-resistant BPA-NI (Bisphenol A Non-Intent) internal coating at 4–8 g/m² coverage:
| Coating Type | Cure Temperature | Application | Juice Compatibility |
|---|---|---|---|
| BPA-NI (polyester-based) | 180–200 °C, 40–55 s | Acid-resistant, BPA-compliant | pH 3.0–4.5 fruit juices |
| Epoxy phenolic | 180–210 °C, 40–55 s | Heavy-duty acid resistance | pH < 3.5 high-acid juices |
| Vinyl organosol | 180–200 °C, 30–45 s | Flexible, impact-resistant | Viscous nectars and pulpy juices |
| PET laminated film | 200–220 °C lamination | Premium barrier | NFC premium juices |
Coating adhesion is tested per ISO 2409 cross-cut method, with rating 0–1 (no delamination) required for juice cans after pasteurization thermal cycling.
3.4 Pasteurization Compatibility — 72 °C / 15 s or UHT 135 °C / 2–5 s
Juice cans must withstand thermal processing after sealing:
- HTST (High-Temperature Short-Time): 72 °C for 15 seconds — standard pasteurization for acidic juices (pH < 4.2)
- UHT (Ultra-High Temperature): 135 °C for 2–5 seconds — for low-acid juices (pH > 4.2) or extended shelf-life products
- Hot-fill: 85–95 °C juice filled directly into cans, sealed, then inverted for cap/pasteurization
The can seam must maintain integrity through these thermal cycles without:
- Sealant softening or flow
- Coating delamination from thermal shock
- Differential expansion between body and end causing micro-gaps
Yongxin’s 5-layer mechanical seam (BHB ≥ 45 %, thickness 1.15–1.35 mm) is rated for repeated thermal cycling. The sealing compound (typically rubber-based) maintains elasticity through pasteurization temperatures up to 135 °C.

4.3 Three Signature Technologies Applied to Juice Can Lines
1. 8-Cam 8-Roller Synchronous Seaming Head The eight-cam, eight-roller configuration ensures uniform pressure distribution across all points of the double seam, producing consistent seam thickness of 1.15–1.35 mm with ± 0.05 mm tolerance. For juice cans, this consistency is essential to maintain the O₂ barrier < 50 ppb across every production unit — a single weak seam in a juice can leads to oxidative spoilage of the entire batch.
2. Dual-Groove Flanging Wheel with Linear Guide The internal-external dual-groove flanging system uses precision bearings and linear guides to prevent spring fatigue fracture — a common failure mode in high-speed flanging. For juice can production, consistent flange geometry ensures proper engagement with the seaming head, maintaining the hermetic seal through pasteurization thermal cycling. Yongxin’s design extends flanging wheel life by 2–3× compared to single-groove configurations.
3. CN118025556B Synchronous Continuous Lid Feeder Patented in May 2026, this mechanism (CN118025556B) synchronizes lid delivery with can body positioning at ± 0.1 mm accuracy, eliminating lid misalignment that can cause incomplete seam formation. For juice cans requiring hermetic O₂ barriers, this precision prevents the most common cause of seam-related O₂ ingress.

11. Welding Technology for Juice Cans
Juice cans typically use 0.18–0.25 mm tinplate, requiring precise welding parameters:
| Parameter | Juice Can Range | Notes |
|---|---|---|
| Cu-wire diameter | Ø1.35–1.50 mm | Standard for 0.18–0.25 mm tinplate |
| Welding current | 18–40 KVA | Adjusted for material thickness |
| Overlap width | 0.8–1.2 mm | Consistent overlap ensures hermetic seam base |
| Weld speed | 20–80 can/min | Matches line CPM |
| Wire consumption | ~0.3 m per can | Cu-wire consumable cost factor |
Yongxin’s welding stations use SMC/Airtac pneumatic components and imported sensors for consistent wire feed and pressure control. The welding zone receives internal stripe touch-up lacquer before the cure oven (200–210 °C), ensuring the bare metal at the weld is protected from juice acid attack.
Four-fold welding quality verification:
- Visual inspection — uniform bead, no spatter
- Destructive peel test — weld strength ≥ base material
- Metallographic cross-section — full penetration, no voids
- Pressure decay test — zero leak at weld zone

14. FAQ — Juice Can Making Machine
Q1: What is a juice can making machine? A: A juice can making machine is a production line that converts tinplate or TFS sheets into cylindrical cans designed for juice packaging. It integrates sheet feeding, slitting, body forming, welding, flanging, beading, internal coating (acid-resistant BPA-NI), external coating (light-opaque), seaming (hermetic O₂ < 50 ppb), and leak testing — producing 30–80 cans per minute on Yongxin's standard and high-speed lines.
Q2: How is a juice can making machine different from a beverage can machine? A: Juice cans require acid-resistant internal coatings (BPA-NI 4–8 g/m² for pH 3.0–4.5), full light opacity (UV 350–500 nm blocking for vitamin C protection), and pasteurization compatibility (72 °C / 15 s or UHT 135 °C / 2–5 s). Beverage can machines may not include these juice-specific stations. See the beverage can making machine comparison for details.
Q3: What can sizes can a Yongxin juice can line produce? A: Yongxin’s small round can lines handle Ø60–180 mm diameter and 65–330 mm height, covering standard juice can sizes: 330 ml (Ø66 × 115 mm), 355 ml (Ø66 × 120 mm), 500 ml (Ø66 × 165 mm), and 150 ml slim (Ø52 × 72 mm). Can changeover takes approximately 5 minutes with servo-driven adjustment.
Q4: What is the O₂ barrier requirement for juice cans? A: Juice cans require hermetic seams with oxygen ingress below 50 ppb (parts per billion) dissolved oxygen. This is achieved through Yongxin’s 8-cam 8-roller synchronous seaming head producing a 5-layer double seam (1.15–1.35 mm thickness, BHB ≥ 45 %) combined with nitrogen headspace flushing. For premium NFC juices, some producers target < 20 ppb.
Q5: Why do juice cans need light-opaque coating? A: UV light at 350–500 nm degrades vitamin C (ascorbic acid) and carotenoids in juice through photo-oxidation. Tinplate substrate provides 100 % inherent light opacity, supplemented by external opaque coatings for additional UV blocking at seam overlaps. High-voltage pinhole testing at 15–25 kV verifies coating continuity.
Q6: What internal coating is used for juice cans? A: BPA-NI (Bisphenol A Non-Intent) polyester-based coating at 4–8 g/m² is the standard for juice cans, cured at 180–200 °C for 40–55 seconds. For high-acid juices (pH < 3.5, e.g., cranberry, lemon), epoxy phenolic coating at 4–14 g/m² provides heavier protection. Both comply with FDA 21 CFR 175.300 and EU 1935/2004.
Q7: Can Yongxin’s juice can line handle pasteurization? A: Yes. Yongxin’s juice can lines are designed for HTST pasteurization (72 °C / 15 s) and UHT treatment (135 °C / 2–5 s). The 5-layer mechanical seam (BHB ≥ 45 %) and sealing compound maintain integrity through thermal cycling. Pasteurization simulation tests are part of the standard QC protocol.
Q8: What is the production speed of Yongxin juice can lines? A: The Small Round Can Standard Line produces 30–40 CPM (8 kW, 2,700 kg), and the High-Speed Line produces 60–80 CPM (12 kW, 5,300 kg). Annual output ranges from 5 million to 80 million+ cans depending on configuration and shifts.
Q9: What is the price range for a juice can making machine line? A: Entry-level configurations (Standard 30–40 CPM + semi-auto sealer) start from approximately USD 80,000–150,000. Growth-tier lines (High-Speed 60–80 CPM + auto sealer + coating station) range from USD 200,000–350,000. Full-scale configurations reach USD 350,000–550,000+. Contact Yongxin’s engineering team for a detailed quotation.
Q10: Which markets has Yongxin exported juice can equipment to? A: Yongxin has exported can-making equipment to Southeast Asia (Thailand — 3 lines, Vietnam — 2 lines), South Asia (India — 1 line), and the Middle East (Saudi Arabia — 1 line). While these exports include various can types, the juice can production capability is available on the small round can line platforms used across these installations.
Q11: What substrate materials work for juice cans? A: ETP (Electrolytic Tin Plate) #25–#50 at 0.18–0.25 mm is the primary substrate for juice cans. For high-acid juices (pH < 3.5), ETP #50–#75 provides additional corrosion resistance. TFS (tin-free steel / chromium-coated) at Cr 50–200 mg/m² offers a cost-effective alternative for mild juices. All substrates are compatible with Yongxin's welding and seaming systems.
Q12: How long does it take to install and commission a juice can line? A: The standard timeline is: manufacturing (60–90 days) + sea freight (18–45 days) + on-site commissioning (7–21 days). Yongxin’s 47-person team including senior mechanical R&D engineers provides 48-hour on-site installation for domestic clients and international commissioning support with video guidance for overseas buyers.
