宝钢覆膜铁产品手册
宝山钢铁股份有限公司 | BAOSHAN IRON & STEEL CO.,LTD.

1. 简介 / Introduction

覆膜铁是由高分子树脂薄膜和钢板组成的环保包装材料,主要通过熔融法将聚对苯二甲酸乙二醇酯(PET)等薄膜覆合于镀铬板(TFS)、镀锡板(ETP)、冷轧板表面。其具备优良的耐腐蚀、耐加工、易印刷性能,可有效保障食品安全,使包装外观艳丽。

Laminated Steel is a green and low-carbon packaging material made of polymer film and steel base. It combines steel strips (such as TFS, ETP, cold rolling steel) with resins (such as PET) by heating and melting, with excellent corrosion resistance, formability and printability to ensure food safety.

宝钢股份是中国主要的镀锡产品制造商之一,拥有先进工艺装备、丰富生产管理经验及一流研发制造队伍。其高端覆膜铁产线集成基板全流程技术、薄膜技术、覆膜工艺及装备技术,配备在线质量监测与精确控制技术,实现产品稳定生产,已广泛应用于食品、饮料、化工等领域包装,获得用户认可。

Baosteel is one of the major manufacturers of tin-mill products in China. Its self-developed high-level laminated steel line integrates base steel process, film technology and online quality control, ensuring stable product performance. The product is widely used in food, beverage and chemical packaging with a good reputation.
