Europe remains the dominant consumption region, anchored by culinary traditions in France, Italy, Poland, and the UK. The European jam market reached USD 3.01 billion in 2025 and is projected to reach USD 3.55 billion by 2030 at 3.36% CAGR (Mordor Intelligence, 2025). Asia-Pacific is the fastest-growing frontier: China leads at 6.1% CAGR, followed by the USA (5.6%), Germany (5.3%), and New Zealand (5.4%) (Future Market Insights, 2026).
Metal Packaging for Jam: Positioning Within the Packaging Matrix
Jam packaging materials include glass jars, plastic containers, metal tins, and flexible pouches. Glass jars currently dominate the jam packaging segment due to visual product display and consumer perception of premium quality. However, metal tins offer distinct advantages:
- Complete light barrier — prevents photo-oxidation of fruit pigments and vitamins
- Superior mechanical strength — withstands stacking, transport impact, and retort sterilization
- Longer shelf life — 2–5 years for tinplate vs. 1–3 years for glass in comparable products
- Recyclability — tinplate achieves a 95%+ theoretical recovery rate with a lifecycle carbon footprint of 1.78 tonnes CO₂ equivalent per tonne, 37.2% lower than PET and 21.5% lower than aluminum (China Circular Economy Association, 2024)
The global tinplate for packaging market was valued at USD 16.1 billion in 2025, projected to reach USD 21.55 billion by 2032 at 4.25% CAGR (Pmarket Research, 2026). Food packaging accounts for 59.9% of tinplate demand, with single-reduced tinplate holding 65.8% share (Pmarket Research, 2026).
Metal tins for jam occupy a specialized niche — particularly for foodservice portions (15–35 g sachets converted to tin), gift packaging, and export-grade preserves where transport durability is critical. In the EU, glass jars accounted for 37.6% of jam packaging in 2024, while single-serve packs are growing at 4.3% CAGR through 2030 (Mordor Intelligence, 2025).

Jam Tin-Specific Process Requirements
Acid-Resistant Internal Coating (BPA-NI)
Fruit preserves with pH 3.5–4.2 require BPA-NI (Bisphenol A – Not Intended) coatings at 8–14 g/m² coverage. This coating must withstand both the acidity of the fruit and the hot-fill temperatures of 85–95°C without degradation, delamination, or flavor scalping. The EU banned BPA in food contact materials in December 2024, making BPA-NI coatings mandatory for all EU-market jam tins. The curing temperature for BPA-NI is 200–220°C, and complete crosslinking is essential for acid resistance.
High Sugar Protection (65°+ Brix)
Jam’s sugar concentration of 65°+ Brix creates osmotic pressure that can drive sugar crystallization at micro-defects in the coating. The internal lacquer must provide uniform coverage without pinholes — particularly at the double seam area where metal deformation is most severe. Coating weight in the seam overlap zone should remain ≥ 6 g/m² to prevent sugar crystal penetration.
Hot-Fill Compatibility
Jam tins must withstand jar pre-heating at 85–95°C before filling. The tinplate structure and internal coating must resist thermal shock without buckling or coating softening. This requires careful selection of tinplate temper grade (T-3 to T-4) and coating polymer that maintains adhesion at elevated temperatures.
Vacuum Sealing Performance
Jam is typically filled hot and sealed under vacuum of 35–50 kPa to prevent microbial growth and preserve color. The double seam must maintain hermetic integrity under both vacuum stress and the thermal contraction that occurs as the product cools from 85–95°C to ambient. Seam specifications include: seam thickness 1.15–1.35 mm, overlap tolerance ±0.05 mm, and body hook balance (BHB) ≥ 45%.
Wide-Mouth Design
Jam tins feature wide openings (Ø65–99 mm) to facilitate both industrial filling of viscous fruit preserves and consumer access. This requires precise flanging and necking that maintains structural rigidity despite the large aperture ratio.

Key Technologies & Patented Innovations
1. Eight-Cam Eight-Roller Synchronous Seaming Head
The patented seaming mechanism employs 8 cams and 8 rollers operating in synchronized sequence to form the double seam in a single continuous rotation. This design ensures:
| Parameter | Specification |
|---|---|
| Seam thickness | 1.15–1.35 mm |
| Thickness tolerance | ±0.05 mm |
| Body hook balance (BHB) | ≥ 45% |
| Seam layers | 5-layer interlocking structure |
| Cam material | High-carbon alloy steel, HRC 58–62 |
| Roller bearing | Imported precision bearing, L10 life > 8,000 hours |
The 8-cam system distributes forming forces evenly around the can circumference, reducing localized stress on the tinplate — critical for maintaining vacuum integrity at 35–50 kPa in jam tins.
2. Internal/External Dual-Groove Flanging Pulley
The dual-groove pulley design for flanging operations provides:
- 2–3× tool life compared to single-groove configurations
- Consistent flange width across production runs
- Reduced vibration at high CPM speeds
- Lower maintenance frequency — groove changeover every 500,000+ cycles
This technology is integrated across all Yongxin production lines, including Lines C and D for square jam tins.
3. Patent CN118025556B: Synchronized Continuous Lid Feeding and Supply Device
This patent covers a 罐体封盖同步连续落盖供应装置 (can body and lid synchronized continuous feeding and supply device) with:
| Parameter | Specification |
|---|---|
| Lid feeding accuracy | ±0.1 mm |
| N₂ flushing integration | Compatible with inert gas injection |
| Feeding speed | Synchronized with line CPM |
| Jam detection | Auto-stop on lid misalignment |
The N₂ flushing capability is particularly relevant for jam tins — inert gas injection before seaming displaces residual oxygen, extending product shelf life and preserving fruit color and flavor. This is especially valuable for light-colored fruit preserves (peach, apricot, pear) where oxidation causes visible browning.
For more on seaming technology, see Can Seaming Machine China 2026.
Internal Coating Systems for Jam Tins

Sustainability & Circular Economy
Metal packaging for jam contributes to circular economy objectives:
| Metric | Tinplate | Glass | PET |
|---|---|---|---|
| Recycling rate | ~80% (EU average) | ~76% (EU average) | ~52% (EU average) |
| Lifecycle CO₂ per tonne | 1.78 tonnes | ~2.8 tonnes | ~2.78 tonnes |
| Weight per 500g container | ~45 g | ~300 g | ~35 g |
| Transport efficiency | High (nestable, lightweight) | Low (heavy, fragile) | High |
| Closed-loop potential | Steel scrap → new tinplate (infinite cycles) | Crush → new glass | Degrades after 2–3 cycles |
The EU Packaging and Packaging Waste Regulation (PPWR) targets 70% recycling rate for metal packaging by 2030. Tinplate’s magnetic separability makes it straightforward to recover from waste streams. In China, 297 million tonnes of scrap tinplate were recovered in 2024, a 7.6% year-on-year increase, with the recycling rate reaching 78.3% (China Circular Economy Association, 2024).
For jam producers, specifying tinplate from certified recycled steel sources and partnering with equipment manufacturers who support lighter-gauge tinplate (down to 0.16 mm) can reduce both material costs and carbon footprint without compromising package integrity.
Frequently Asked Questions (FAQ)
1. What is a jam tin making machine?
A jam tin making machine is an automated production line that manufactures metal containers (tins) from tinplate for packaging fruit preserves, jam, marmalade, and similar high-acid, high-sugar food products. It integrates flanging, welding, seaming, beading, internal coating, and leak detection into a single continuous production flow.
2. What tinplate thickness is suitable for jam tins?
Jam tins typically use ETP (Electrolytic Tinplate) #25 with steel thickness of 0.16–0.25 mm. The lighter gauge (0.16–0.20 mm) is common for 100–370 g retail jam tins, while 0.20–0.25 mm is preferred for 500 g–1 kg formats that require higher rigidity for vacuum resistance.
3. Why is internal coating critical for jam tins?
Jam has a pH of 3.5–4.2 (high-acid) and sugar content above 65° Brix, which together attack bare tinplate through corrosion and sugar crystallization. Internal coatings — typically BPA-NI at 8–14 g/m² — provide a chemical barrier that prevents metallic taste transfer, sulfide staining, and coating delamination. The coating must also withstand hot-fill temperatures of 85–95°C.
4. Can Yongxin machines produce both round and square jam tins?
Yes. Yongxin offers round can lines (Lines A, B, E) handling Ø60–300 mm and square/rectangular can lines (Lines C, D, F) handling diagonal dimensions up to 320 mm. Round tins are standard for retail jam, while square/rectangular tins are popular for premium gift packaging.
5. What is the production speed range for jam tin making machines?
Yongxin’s production lines cover 25–80 CPM (cans per minute). The Small Round High-Speed Line achieves 60–80 CPM for high-volume production, while the Small Round Standard Line operates at 30–40 CPM for mid-volume operations. Single machines operate at 12–80 CPM depending on type.
6. What voltage do Yongxin machines require?
All Yongxin production lines operate on 380V, 3-phase, 50Hz power supply. For markets with different voltage standards (e.g., 220V/60Hz in some countries), the electrical system can be customized during manufacturing.
7. How long does delivery take?
Standard delivery lead time is 60–90 days from order confirmation. This includes engineering design (15–20 days), material procurement (15–20 days), manufacturing and assembly (20–30 days), testing and FAT (5–10 days), and shipping to Southeast Asia (7–15 days).
8. What payment terms does Yongxin offer?
Yongxin follows a 30-30-30-10 payment structure: 30% advance upon order confirmation, 30% progress payment after frame assembly, 30% pre-shipment after successful Factory Acceptance Test, and 10% warranty deposit payable 12 months after commissioning.
9. Are BPA-NI coatings mandatory for jam tin production?
For jam tins destined for the European Union, BPA-NI coatings are effectively mandatory following the European Commission’s December 2024 ban on BPA in food contact materials, with full compliance required by January 2028. For the US market, while federal FDA regulations still technically permit BPA, major retailers (Walmart, Whole Foods) require BPA-NI declarations, and California’s Proposition 65 mandates BPA warnings. In practice, BPA-NI is the global standard for jam tin coatings.
10. What is the difference between jam tins and regular food cans?
Jam tins differ from general food cans in three key aspects: (1) acid-resistant internal coating (8–14 g/m² vs. standard 6–10 g/m²) to handle pH 3.5–4.2; (2) wider mouth openings (Ø65–99 mm) for filling viscous preserves; (3) vacuum sealing requirements of 35–50 kPa for hot-fill products. The seaming specifications remain similar, but the coating weight at the seam overlap zone must be maintained at ≥ 6 g/m² to prevent sugar crystal penetration.
11. Can the machines handle nitrogen flushing for extended shelf life?
Yes. Yongxin’s patented technology (CN118025556B) includes a synchronized continuous lid feeding and supply device that integrates N₂ (nitrogen) flushing capability. Nitrogen injection before seaming displaces residual oxygen inside the can, extending shelf life and preserving fruit color — particularly important for light-colored fruit preserves like peach, apricot, and pear jam.
12. What after-sales support does Yongxin provide?
Yongxin provides on-site commissioning with installation and calibration at the customer’s facility, operator training covering machine operation, maintenance, and troubleshooting, a 12-month warranty covering parts and technical support, and ongoing spare parts supply. Remote diagnostic support via PLC connectivity is available for lines equipped with communication modules.
13. How quickly can the production line change between different jam tin sizes?
For the Small Square Can lines (Lines C and D), format changeover takes approximately 5 minutes with automatic terminal detection at ±0.1 mm accuracy. Round can lines feature simplified changeover mechanisms, though exact time depends on the diameter range change.
14. What quality certifications do Yongxin machines carry?
Yongxin holds National High-Tech Enterprise certification (GR202536000972), ISO 9001 quality management certification (certificate number 107325Q1009R0S), and Jiangxi Province “Specialized & Sophisticated” SME designation. The company holds 86 patents and 6 software copyrights covering core technologies in seaming, flanging, and lid feeding.
15. What is the expected lifespan of a jam tin making machine?
With proper maintenance following the 5-level preventive maintenance schedule (daily, weekly, monthly, quarterly, annual), Yongxin production lines are designed for 15–20 years of operational service. Critical wear components (cam rollers, flanging pulleys) have typical replacement intervals of 500,000–1,000,000 cycles depending on operating conditions.
