Rigorous dimensional accuracy, zero micro-leakage guarantees, and food-grade safety certifications for continuous automated filling lines.
The global food, nutritional dairy, and high-value chemical packaging sectors are undergoing a massive technological transformation. Traditional ring-pull Full Open Ends (FOE) and steel easy-open lids are rapidly being superseded by Aluminium Peel Off Ends (POE). Driven by stringent global safety norms (eliminating sharp metal edge hazards), ultra-high oxygen barrier demands, and carbon reduction initiatives, modern packaging engineers specify Peel Off Ends for high-integrity sealing.
As a Global Leading Aluminium Peel Off End Manufacturer & Supplier, Shanghai Friend Metals Technology Co., Ltd. integrates advanced metallurgical extrusion, precision high-speed stamping, and multi-layer heat-sealing technologies. By combining 8011-H18 / 8011-O micro-embossed foil membranes with high-strength 5182-H48 aluminum or tinplate outer ring shells, our POE systems deliver unmatched peelability without sacrificing burst strength or gas tightness.
Information Gain Insight: Our proprietary thermal bonding layer permits hermetic sealing at temperatures 15% lower than industry averages, preventing thermal distortion of internal lacquers and maintaining zero-leakage performance under Modified Atmosphere Packaging (MAP) gas flushing.
According to global packaging market analysis, the demand for soft-aperture aluminum peel-off ends is expanding at a 6.8% CAGR. Key drivers include:
From alloy chemistry to heat-seal lacquer polymers: detailing the technical layers behind flawless barrier protection.
We utilize prime-grade 5182-H48 aluminum for ring shells requiring high buckle resistance, and 8011-O / 8011-H18 state-of-the-art aluminum foil for flexible membranes. Outer tinplate rings are optioned with TH330+CA temper for economic rigidity.
Engineered with non-organosol, BPA-NI (BPA Non-Intent) food-contact lacquers. Co-extruded PP (Polypropylene), PE, or PET film coatings ensure uniform seal strength across standard 200#, 211#, 300#, 307#, 401#, and 502# diameter sizes.
Optimized tab geometry and grid embossing lower the initial tab pop force (<15 N) and continuous peel force (8–18 N), guaranteeing easy access for senior citizens and children while maintaining resistance to internal pressure spikes.
| Industry Code | Nominal Diameter | Ring Substrate / Alloy | Foil Thickness (μm) | Internal Coating System | Target Application |
|---|---|---|---|---|---|
| 211# POE | 65 mm | Aluminium 5182-H48 / Tinplate | 60 - 70 μm (Embossed) | BPA-NI PP / Polyolefin Film | Specialty Coffee, Milk Powder, Spices |
| 300# POE | 73 mm | Aluminium 5182 / TFS Ring | 70 - 80 μm (Custom Printed) | Organosol-Free Retortable Polymer | Nuts, Cereal, Ready-to-Eat Snacks |
| 307# POE | 83 mm | Prime Tinplate / Aluminium | 70 - 90 μm (Grid Pattern) | High-Temperature Steam Sterilizable | Canned Meats, Fish, Wet Pet Food |
| 401# POE | 99 mm | Aluminium 5182-H48 Heavy-Duty | 80 - 90 μm (Soft Peel) | FDA 21 CFR 175.300 Compliant PE | Infant Formula, Adult Nutrition Powders |
| 502# POE | 127 mm | Reinforced Aluminium / Tinplate | 85 - 100 μm (High-Barrier) | Anti-Static / Anti-Corrosion Barrier | Bulk Food Processing, Industrial Powders |
Deploying customized material science to protect product purity, prevent oxidation, and enhance brand loyalty.
Infant formula requires absolute barrier purity. Our 401# and 502# Peel Off Ends are produced in ISO Class 8 cleanroom environments. The soft foil top ensures zero metal shavings contaminate the scoopable powder, maintaining pristine hygiene standards.
Protecting delicate aroma compounds from volatile degradation demands near-zero oxygen ingress. We integrate custom degassing valves directly into aluminum peel-off membranes for roasted coffee cans, permitting CO₂ escape without ambient O₂ back-flow.
Our thermal-resistant 307# and 401# POE ends are built to withstand high-pressure steam sterilization (121°C for 45 minutes). The heat-seal compound resists acidic and fatty food media, preventing delamination during thermal processing.
For high-purity technical powders, static electricity can cause dust accumulation along the seaming rim. We offer specialized anti-static 300# aluminum easy-open ends that bleed off static charges during rapid vacuum filling.
Our engineering protocols strictly adhere to Google Search Quality Rater E-E-A-T expectations, demonstrating deep operational experience, technical authority, and reliable manufacturing oversight.
Every batch of coated aluminum coil undergoes high-voltage enamel rating testing (<2 mA specification), ensuring zero micro-porosity or pinhole fractures in the lacquer matrix prior to stamping.
Our optical seam projection analyzers inspect seam tightness (>85%), overlap length, body hook, and cover hook dimensions against precise client seamer tooling tolerances.
Fully documented compliance declarations for FDA 21 CFR 175.300, EU Commission Regulation (EU) No 10/2011, REACH, RoHS, and GB 4806.10 food-grade migration standards.
Pioneering next-generation sustainable foil technologies and digital traceability.
Reducing foil membrane thickness down to 50 μm using high-tensile 8079 alloys without compromising puncture resistance.
Transitioning from fossil-derived heat-seal polymers to 100% plant-based, renewable barrier lacquers.
Direct laser-engraved serialized QR codes on peel-off foils for anti-counterfeiting and farm-to-table consumer tracking.
Sourcing 100% hydro-powered recycled aluminum coil stock to lower Scope 3 carbon footprint for global brand owners.
Shipping lightweight aluminum ends worldwide requires specialized export packaging to eliminate transit denting, oxidation, and stack collapse. Every shipment from Shanghai Friend Metals is engineered for extreme maritime conditions.
