塑料包裝印刷經常用到的材料有哪些？

　　塑料袋,購物袋,真空包裝袋,透明包裝袋……這些在市面上隨處可見，到處可買，但這些塑料包裝印刷的原料是些什么呢，相信很少有人知曉。以下是羿彩塑料包裝印刷部為大家簡單整理常用原料品種性能及用途。
　　Plastic bags, shopping bags, vacuum bags, transparent bags... These on the market can be seen everywhere, everywhere can buy, but the plastic packaging and printing of the raw material is what, believe that few people know. Below is the processing of color plastic packaging printing for everybody simple sorting common raw material variety properties and USES.
　　1．聚丙烯：相對來說，聚丙烯的品種更多，用途也比較復雜，領域繁多，品種主要有均聚聚丙烯（homopp），嵌段共聚聚丙烯（copp）和無規共聚聚丙烯（rapp）。
　　Polypropylene:  Relatively speaking, more variety of polypropylene, use also is more complex, area is various, main varieties have all polyethylene polypropylene (homopp), block copolymerization polypropylene (copp) and random copolymerization polypropylene (rapp).
　　2．聚乙烯：常用聚乙烯可分為低密度聚乙烯（LDPE）、高密度聚乙烯（HD特種塑料PE）和線性低密度聚乙烯（LLDPE）。三者當中，HDPE有較好的熱性能、電性能和機械性能，而LDPE和LLDPE有較好的柔韌性、沖擊性能、成膜性等。
　　Polyethylene: commonly used polyethylene can be divided into low density polyethylene (LDPE), high density polyethylene special plastic PE (HD) and linear low density polyethylene (LLDPE). Among the three, HDPE has good thermal performance, electricity performance and mechanical properties, and the LDPE and LLDPE has better flexibility and impact performance, film, etc.
　　3．聚苯乙烯：作為一種透明的原材料，在有透明需求的情況下，用途廣泛，如汽車燈罩、日用透明件、透明杯、罐等。
　　Polystyrene: as a kind of transparent materials, under the condition of demand in a transparent, wide range of USES, such as automobile lampshade, daily transparent, transparent glass, cans, etc.
　　4．聚氯乙烯：由于其成本低廉，產品具有自阻燃的特性，故在建筑領域里用途廣泛，尤其是下水道管材、塑鋼門窗、板材、人造皮革等用途最為廣泛。
