Tin Free Steel for Food Packaging with Non-toxic Barrier Properties and Recyclability
Tin free steel adopts low-carbon steel substrate and chromium-chromium oxide composite film design to form a dense protective barrier:
1,Food-grade safety protection: There is no metal tin coating on the surface to eliminate the risk of tin ion migration. It is tested to be completely free of harmful heavy metals such as lead and cadmium. It can also ensure safety even when in direct contact with food. It is especially suitable for sensitive categories such as infant food and health products.
2,Efficient barrier preservation: The composite film layer can isolate oxygen, moisture and light to prevent food from oxidation and deterioration. It has excellent acid and salt resistance. Whether it is acidic foods such as carbonated beverages and ketchup, or salt-containing scenes such as soy sauce and canned food, it can keep the contents fresh for a long time.
3,High temperature resistant and stable characteristics: It can withstand 121℃ high temperature sterilization process. The packaging will not deform or release harmful substances during processing such as steaming and baking, providing reliable protection for ready-to-eat foods, canned foods, etc.
Environmental advantages: a green choice that is recyclable throughout the entire cycle
1,100% metal is recyclable: the base material is made of steel, which can be completely recycled after being discarded. The surface film layer is decomposed into harmless oxides during the smelting process, which does not affect the quality of recycled steel, and the recycling rate is far higher than that of plastics, glass and other materials.
2,Low-carbon production mode: the process energy consumption is 15% lower than that of traditional tinplate, and the entire life cycle from production to disposal is more environmentally friendly, which is in line with the global "carbon neutrality" trend and helps brands fulfill their green packaging commitments.
Application scenarios: packaging innovation adapted to multiple fields
1,Beverages and dairy products: used in cola cans, milk powder cans, etc., resistant to carbonic acid corrosion and strong sealing, extending the shelf life of beverages;
2,Snack foods and condiments: made into potato chip barrels, soy sauce bottles, etc., moisture-proof and anti-oxidation, maintaining a crisp taste and flavor;
3,High-temperature processed foods: competent for luncheon meat cans and instant porridge packaging, and can still maintain packaging integrity after high-temperature sterilization.
Three reasons to choose Tin Free Steel
1,Safety: No risk of heavy metal migration, passed multiple food contact safety certifications at home and abroad;
2,Reliable performance: Barrier properties are comparable to traditional tinplate, while also having better processing and forming properties;
3,Environmental protection bonus: Recyclable properties help brands meet the green packaging standards of supermarkets and e-commerce platforms, and enhance consumer trust.
