    • A PET-based polyester packaging film capable of weld-cut sealing and heat-shrinkage refers to a film obtained by biaxially orienting a material prepared through block copolymerization of a PET/PETG/polyester elastomer with an epoxy resin and a catalyst. This film eliminates the most serious weak points in physical properties of conventional PET films, and is useful for packaging of books, bottlesets, food containers, etc., for general packaging, packaging of industrial materials, and the like, and is further useful in the field of packing and packaging of daily commodities, civil engineering and construction members, electric and electronic members, and automobile vehicle members, etc. Moreover, this film can be produced through effective use of the huge amount of recycled PET bottles and inexpensive PET for fiber as a prepolymer, and thus is also highly beneficial socially. Still further, even if incinerated after use, this film produces a combustion heat value lower than that of a polyethylene or polypropylene. Thus, this film barely damages incinerators or the like, and emits no toxic gases.
    • 能够进行切割密封和热收缩的PET系聚酯包装膜是指通过PET / PETG /聚酯弹性体与环氧树脂和催化剂的嵌段共聚制备的材料双轴取向而获得的膜。 该膜消除了常规PET膜的物理性能中最严重的弱点,并且用于包装书籍,瓶子,食品容器等,用于一般包装,工业材料包装等,并且还可用于 日用品包装和包装领域,土木工程施工人员,电气电子部件和汽车用品等。此外,该膜可以通过有效利用大量的回收PET瓶和廉价的PET来生产 纤维作为预聚物,因此在社会上也是非常有益的。 此外,即使在使用后焚烧,该膜产生低于聚乙烯或聚丙烯的燃烧热值。 因此,该膜几乎不损坏焚烧炉等,并且不产生有毒气体。
