This guide covers the complete scope of milk powder can manufacturing: what distinguishes a milk powder can from a generic food can, the nitrogen flushing and residual oxygen requirements, international compliance standards, Yongxin’s production line configurations, quality control protocols, global market data from QYResearch and Intel Market Research, and a detailed buyer’s guide for equipment selection.
What Is a Milk Powder Can Making Machine?
A milk powder can making machine is a specialized metal packaging production line designed to manufacture tinplate (or TFS) cans specifically engineered for milk powder and infant formula packaging. Unlike general-purpose food can lines, milk powder can making machines must integrate nitrogen flushing stations, residual oxygen detection, food-grade internal coating systems, and hermetic sealing mechanisms that achieve residual oxygen levels below 1% — a threshold far stricter than most conventional food canning operations.
The global milk powder market was valued at USD 18,460 million in 2025 and is projected to reach USD 20,730 million by 2032, growing at a CAGR of 1.7% (Source: QYResearch, Report 5527694, January 2026). Infant formula milk powder represents the single largest application segment, followed by confectionery and nutritional supplements. This demand directly drives the need for precision milk powder can making equipment capable of meeting the packaging standards that protect product freshness over 18–24 month shelf lives.
How Milk Powder Cans Differ from Generic Food Cans
| Parameter | Milk Powder Can | Generic Food Can (e.g., tuna/vegetable) |
|---|---|---|
| Residual oxygen | <1% (nitrogen-flushed) | Not typically required |
| Atmosphere | Nitrogen inert (purity >99.9%) | Ambient air or vacuum |
| Shelf life target | 18–24 months | 12–36 months (retort) |
| Internal coating | BPA-NI or epoxy phenolic, 4–8 g/m², food-contact certified | Epoxy phenolic, 4–14 g/m² |
| Seal integrity | Hermetic, leak rate <0.5 mL/min | Standard double-seam |
| Typical can diameter | Ø60–100 mm (400 g–900 g) | Ø65–99 mm (307–603 series) |
| Can height | 80–150 mm | 40–170 mm |
| Material thickness | 0.16–0.25 mm (lighter gauge) | 0.18–0.25 mm |
| End closure | Easy-open end (EOE) aluminium + plastic lid | Standard double-seam lid |
| Regulatory framework | FDA 21 CFR 106 + EC 1935/2004 + GB 4806 | FDA 21 CFR 175 + EC 1935/2004 |
| Coating migration | Strict migration limits for infant consumption | Standard food-contact limits |
The critical distinction is the nitrogen flushing requirement: milk powder contains fat-soluble vitamins (A, D, E, K), polyunsaturated fatty acids (DHA, ARA), and probiotics that are highly susceptible to oxidative degradation. Even trace amounts of oxygen (>1% residual O₂) accelerate lipid oxidation, nutrient loss, and off-flavor formation — which is why milk powder cans require a controlled inert atmosphere from the moment of filling through final sealing.

Milk Powder Can Types & Dimensional Standards
Milk powder cans are typically 3-piece round cans (body + top end + bottom end) manufactured from electrolytic tinplate (ETP) or tin-free steel (TFS). The following dimensional matrix covers the standard milk powder can sizes used globally:
Standard Milk Powder Can Size Matrix
| Can Capacity | Net Weight | Outer Diameter (mm) | Height (mm) | Material Thickness (mm) | Typical End Type |
|---|---|---|---|---|---|
| 400 g | 400 g | Ø73 | 113 | 0.16–0.20 | EOE + plastic overcap |
| 500 g | 500 g | Ø83 | 118 | 0.16–0.20 | EOE + plastic overcap |
| 700 g | 700 g | Ø99 | 120 | 0.16–0.22 | EOE + plastic overcap |
| 800 g | 800 g | Ø99 | 131 | 0.18–0.22 | EOE + plastic overcap |
| 900 g | 900 g | Ø99 | 140 | 0.18–0.22 | EOE + plastic overcap |
| 1.0 kg | 1000 g | Ø105 | 148 | 0.18–0.25 | EOE + plastic overcap |
| 1.5 kg | 1500 g | Ø126 | 155 | 0.20–0.25 | Double-seam + overcap |
| 2.5 kg (bulk) | 2500 g | Ø153 | 175 | 0.20–0.25 | Double-seam + overcap |
The 800 g can (Ø99 × 131 mm) is the industry-standard size for infant formula packaging across Asia-Pacific and is the reference format for most major brands (Nestlé NAN, Danone Aptamil, Mead Johnson Enfamil, Feihe, Fonterra Anlene). The 400 g format (Ø73 × 113 mm) is common in Bangladesh and South Asian markets where Morinaga and other Japanese brands operate.
Milk Powder Can Substrate Options
| Substrate | Designation | Coating Weight | Application |
|---|---|---|---|
| Electrolytic Tinplate | ETP | #25–#50 g/m² Sn (both sides) | Infant formula cans — primary choice |
| Tin-Free Steel | TFS (Cr-coated) | 50–200 mg/m² Cr | Milk powder industrial/bulk cans |
| Cold-rolled coated steel | SPCC + Sn coating | 4–12 g/m² tin + internal lacquer | Cost-effective alternative for non-infant milk powder |
For infant formula cans, ETP remains the substrate of choice because of its superior corrosion resistance, solderability for easy-open ends, and proven compatibility with BPA-NI (bisphenol-A non-intent) internal coatings required by major infant formula manufacturers.
International Compliance Standards for Milk Powder Cans
Milk powder cans — particularly those used for infant formula — are subject to some of the strictest food-contact packaging regulations globally:
6 Key Compliance Frameworks
| Standard | Region | Scope | Relevance to Milk Powder Cans |
|---|---|---|---|
| FDA 21 CFR 106 | USA | Infant formula manufacturing (GMP) | Containers/closures must not be reactive or absorptive; food-contact substances must comply with §409(c) or GRAS |
| FDA 21 CFR 175.300 | USA | Indirect food additives — coatings | Internal can coating must comply with extraction limits; BPA-NI coatings preferred for infant formula |
| EC 1935/2004 | EU | Food contact materials framework | Metal cans must not transfer constituents to food in quantities that endanger human health |
| EU 2018/213 | EU | BPA in varnishes/coatings | BPA restricted in varnishes for infant food cans; SML 0.05 mg/kg for infant-targeted coatings |
| GB 4806.10-2016 | China | Food-contact metal materials | Migration limits for tin, chromium, heavy metals; mandatory for domestic infant formula packaging |
| ISO 9001:2015 | Global | Quality management system | Yongxin certified (No. 107325Q1009R0S); ensures traceability and process control throughout can manufacturing |
Internal Coating Requirements for Milk Powder Cans
The internal coating of milk powder cans must satisfy both functional and regulatory criteria:
| Coating Type | Weight (g/m²) | Cure Temperature | BPA Status | Typical Application |
|---|---|---|---|---|
| Epoxy phenolic | 4–8 | 180–210°C, 8–12 min | Contains BPA | General food cans; not preferred for infant formula |
| BPA-NI (non-intent) | 4–8 | 180–200°C, 8–12 min | BPA-free | Infant formula cans (FDA/EU compliant) |
| Polyester | 4–6 | 200–220°C, 10–15 min | BPA-free | Alternative for sensitive formulations |
| Vinyl organosol | 6–10 | 180–200°C, 8–10 min | Variable | High-barrier applications |
For infant formula packaging, BPA-NI coatings are now the industry standard. The EU’s Regulation 2018/213 specifically restricts BPA in varnishes and coatings intended for infant food contact materials, with a specific migration limit (SML) of 0.05 mg/kg — effectively requiring BPA-NI alternatives for infant formula cans entering the European market.
Key Process Requirements Unique to Milk Powder Cans
Milk powder can manufacturing involves four process requirements that distinguish it from conventional food can production:
1. Nitrogen Flushing System (Residual O₂ <1%)
The nitrogen flushing station is the critical differentiator for milk powder can making machines. The process involves three sequential steps:
- Vacuum extraction: The filled can enters a vacuum chamber where ambient air (21% O₂) is partially evacuated
- Nitrogen injection: Food-grade nitrogen (purity >99.9%) is injected at controlled pressure (0.2–0.4 MPa) to displace remaining oxygen
- Immediate sealing: The can is sealed (double-seamed) within the nitrogen atmosphere before any oxygen re-entry is possible
The target residual oxygen level is <1% for premium infant formula, though some equipment specifications cite <2% as an acceptable threshold. Industry data from powder packaging specialists confirms that through vacuum and nitrogen flushing, the residual oxygen can be controlled within 2%, ensuring shelf life of 2–3 years. For infant formula, the stricter <1% threshold provides additional safety margin against lipid oxidation of DHA/ARA fatty acids.
Nitrogen consumption: Approximately 15–25 L/min for continuous can seaming operations, with nitrogen purity >99.9% at supply pressure of 0.4 MPa.
2. Hermetic Seal Integrity (Leak Rate <0.5 mL/min)
The double-seam seal of milk powder cans must maintain hermetic integrity over 18–24 month shelf life under varying temperature and humidity conditions. Key seam parameters:
| Parameter | Specification |
|---|---|
| Seam thickness | 1.15–1.35 mm (5-layer mechanical interlock) |
| Body hook | 1.8–2.2 mm |
| Cover hook | 1.8–2.2 mm |
| BHB (Body Hook Balance) | ≥45% |
| Overlap | ≥1.0 mm |
| Leak rate (He method) | ≤0.5 mL/min |
| Wrinkle | 33–66% of seam thickness |
Yongxin’s 8-cam 8-roller synchronous seaming head achieves these parameters through precision cam-driven tooling that maintains consistent roller pressure across all seam positions — critical for milk powder cans where even minor seal defects can allow oxygen ingress and product degradation.
3. Food-Grade Hygiene Standards
Milk powder can making machines operating in infant formula environments must comply with:
- Material contact surfaces: All food-contact surfaces must be stainless steel (SUS304/SUS316L) or food-grade coated
- Cleaning protocol: CIP (Clean-in-Place) compatible design for production changeovers
- Environmental controls: Can manufacturing cleanroom classification (ISO Class 8 or better) for infant formula can production areas
- Contamination prevention: Dust-free transport systems, positive-pressure can storage, covered conveying
4. Easy-Open End (EOE) Integration
Modern milk powder cans almost universally use aluminium easy-open ends (EOE) with scored tear-strip openings, covered by a reclosable plastic overcap. The EOE must be:
- Compatible with the tinplate can body (dissimilar metal joining via double-seam)
- Scored to open with <15 N force for consumer convenience
- Lined with food-grade sealing compound on the curl
- Protected by a UV-printed plastic overcap for moisture barrier after opening

3 Signature Technologies Applied to Milk Powder Cans
① 8-Cam 8-Roller Synchronous Seaming Head Eight independent cams drive eight sealing rollers in synchronized sequence, producing a 5-layer mechanical double seam with thickness control of 1.15–1.35 mm. For milk powder cans, this precision is critical — the hermetic seal must prevent oxygen ingress over 18–24 months of shelf life. The synchronous design eliminates cumulative tolerance stacking that can cause seal failures at high speeds.
② Internal-External Dual-Groove Flanging Wheel Yongxin’s patented dual-groove flanging wheel (with precision bearings) produces both internal and external flanges in a single pass. The dual-groove design distributes mechanical stress across two contact points rather than one, reducing spring steel fatigue and extending tooling life by 2–3× compared to single-groove alternatives. For milk powder cans, the flange must be precisely formed to accept the EOE (easy-open end) aluminium lid without distortion.
③ CN118025556B — Synchronous Continuous Lid Feeding Patented in May 2026, this mechanism ensures precise lid placement at ±0.1 mm accuracy at production speed. For milk powder cans, where the EOE must align perfectly with the flanged can body before seaming, this patent eliminates the misalignment issues that cause seal defects and oxygen leakage.
Welding Technology for Milk Powder Cans
Milk powder cans typically use thinner gauge materials (0.16–0.22 mm ETP) compared to paint or chemical cans (0.20–0.40 mm). The welding parameters must be adjusted accordingly:
| Parameter | Milk Powder Can (Thin Gauge) | Paint/Chemical Can (Thick Gauge) |
|---|---|---|
| Material thickness | 0.16–0.22 mm | 0.20–0.40 mm |
| Cu-wire diameter | Ø1.35–1.50 mm | Ø1.35–1.70 mm |
| Welding power | 18–40 KVA | 50–125 KVA |
| Overlap width | 0.8–1.0 mm | 0.8–1.2 mm |
| Electrode force | 800–1,500 N | 1,500–3,000 N |
Four-Level Welding Quality Verification:
- Visual inspection: Uniform weld bead, no spatter, no burn-through
- Peel test: Seam peel strength ≥80% of base metal strength
- Hydrostatic test: Pressure test at working pressure × 1.5
- Salt spray test: ASTM B117 compliant — 24-hour exposure for tinplate cans
For milk powder cans, the thin-gauge welding requires precise current control to prevent burn-through while maintaining full penetration. Yongxin’s small can welder (18 KVA, Cu-wire Ø1.38/1.50 mm, speed 20–40 can/min) is optimized for this gauge range.

Frequently Asked Questions (FAQ)
Q1: What is a milk powder can making machine? A: A milk powder can making machine is a specialized metal packaging production line that manufactures tinplate cans for milk powder and infant formula, integrating nitrogen flushing stations (residual O₂ <1%), food-grade internal coating systems, and hermetic double-seam sealing — distinguishing it from general food can lines that do not require inert atmosphere packaging.
Q2: Why does milk powder packaging require nitrogen flushing? A: Milk powder contains fat-soluble vitamins (A, D, E, K), polyunsaturated fatty acids (DHA, ARA), and in some cases probiotics that are highly susceptible to oxidative degradation. Nitrogen flushing displaces oxygen (target: residual O₂ <1%) to prevent lipid oxidation, nutrient loss, and off-flavor formation, extending shelf life to 18–24 months.
Q3: What residual oxygen level is required for milk powder cans? A: For premium infant formula, residual oxygen must be <1%. For adult milk powder and general dairy powder, <2% is generally acceptable. Industry packaging equipment specifications confirm that through vacuum and nitrogen flushing, residual oxygen can be controlled within 2%, with the stricter <1% threshold providing additional safety for infant formula.
Q4: What can sizes does Yongxin’s milk powder can line support? A: Yongxin’s Small Round Can Lines support diameters from 60 to 180 mm and heights from 65 to 330 mm, covering all standard milk powder can sizes from 400 g (Ø73 × 113 mm) to 1 kg (Ø105 × 148 mm). The high-speed line achieves 60–80 CPM; the standard line achieves 30–40 CPM.
Q5: Is BPA-NI coating required for milk powder cans? A: For infant formula cans entering the EU market, yes — EU Regulation 2018/213 restricts BPA in varnishes for infant food contact materials with an SML of 0.05 mg/kg. For the US market, FDA 21 CFR 106 requires infant formula containers to comply with food-contact substance regulations. BPA-NI coatings are the industry standard for infant formula packaging globally.
Q6: What certifications does Yongxin hold for food-grade can equipment? A: Yongxin holds National High-Tech Enterprise certification (GR202536000972), ISO 9001:2015 quality management (No. 107325Q1009R0S), Jiangxi Provincial “Specialized & Sophisticated” SME status, National Tech SME certification, 2024 Tax Credit Grade A, and 86 patents including CN118025556B. All equipment is designed to FDA and EU food-contact compliance standards.
Q7: What is the production capacity of a milk powder can line? A: At 30–40 CPM (standard line), annual output is approximately 12.96–17.28 million cans (assuming 75% OEE, 300 operating days). At 60–80 CPM (high-speed line), annual output is 25.92–34.56 million cans. Yongxin’s high-speed food can sealers (200–600 CPM) can achieve even higher volumes for dedicated infant formula can operations.
Q8: Can Yongxin add nitrogen flushing to an existing can line? A: Yes. The nitrogen flushing station is designed as a modular add-on that can be integrated into existing Yongxin can lines (or compatible third-party lines). The N₂ station includes vacuum chamber, nitrogen supply system, and residual O₂ detection, typically adding USD 25,000–45,000 to the line investment with a 30–45 day lead time.
Q9: What is the delivery lead time for a complete milk powder can line? A: A standard Small Round Can Line (30–40 CPM) has a lead time of 60–90 days from order confirmation. With nitrogen flushing station integration, total lead time is 75–120 days. High-speed lines (60–80 CPM) and high-speed sealers (200–600 CPM) have 60–90 day lead times. FOB Shanghai/Ningbo port.
Q10: Does Yongxin provide installation and training for milk powder can lines? A: Yes. Yongxin provides 48-hour on-site installation and commissioning (domestic), lifetime technical training, lifetime maintenance support, and remote diagnostics via OPC UA/HMI VPN for international customers. For overseas installations, the engineering team provides on-site commissioning (typically 7–21 days) with local team response for follow-up support.
Q11: What payment terms does Yongxin offer? A: Standard payment terms are 30-30-30-10: 30% deposit upon order, 30% before shipping, 30% against Bill of Lading copy, and 10% after commissioning acceptance. This structure protects both buyer and seller throughout the equipment procurement cycle.
Q12: Which markets has Yongxin exported to? A: Yongxin has verified export deliveries to Thailand (3 lines), Vietnam (2 lines), India (1 line), and Saudi Arabia (1 line). The company actively serves markets across Southeast Asia (Philippines, Indonesia, Malaysia), South Asia (Bangladesh, India, Pakistan), Middle East (Saudi Arabia, UAE), Africa (Nigeria, Ghana, Kenya), and South America (Brazil, Peru).
