High barrier composite tensile film

产品特点
Product characteristics

该产品是根据不同的使用要求,以PVDC/EVOH/PA等高阻隔层为中间层,将其与其它材料通过粘合剂粘合在一起,从而赋予产品特殊的功能。根据使用方式的不同可分为上膜(盖膜)和下膜(底膜)。
This product uses high barrier layers such as PVDC/EVOH/PA as the intermediate layer according to different usage requirements, and is bonded together with other materials through adhesives, thus endowing the product with special functions. According to different usage methods, it can be divided into upper film (cover film) and lower film (bottom film).

可根据用户要求,量身定制,为用户研制开发特殊结构,满足不同的使用条件。

We can customize according to user requirements and develop special structures to meet different usage conditions.
