产品特点
Product characteristics

高阻隔PVDC肠衣膜是使用共聚高阻隔PVDC（VC型）高阻隔树脂经过特种设备熔融挤出并经过平吹的方法吹制而成的一种片状薄膜，具有阻隔性优异、热收缩率高、贴体性好，可进行高温杀菌处理，能进行很好的表印和里印印刷、色相丰富的特点。广泛应用于火腿肠外包装。
High barrier PVDC casing film is a sheet-like film made by using copolymerized high barrier PVDC (VC type) high barrier resin, which is melted and extruded by special equipment and blown by flat blowing method. It has excellent barrier properties, high thermal shrinkage rate, good fit properties, and can be subjected to high-temperature sterilization treatment. It can perform good surface and inner printing, and has rich color hue. Widely used in ham sausage packaging.

产品性能
Product performance

1、高效阻隔氧，气味，有效延长食品保质期
