OPP袋和PE袋的鲜明优点！

OPP袋是一种可拉伸的聚丙烯塑料，实际上是一种塑料袋，其特点是易于燃烧。火焰情况:熔融滴落，黄色下有蓝色，从火中冒出较少烟雾后，继续燃烧。
　　OPP bag is a kind of stretchable polypropylene plastic, which is actually a kind of plastic bag. Its characteristic is easy to burn. Flame condition: melt dripping, blue under yellow, less smoke from the fire, continue to burn.
　　取向聚丙烯(OPP):取向聚丙烯(薄膜)，是聚丙烯的一种类型和双向聚丙烯(BOPP)
　　Oriented polypropylene (OPP): Oriented polypropylene (film), a type of polypropylene and bidirectional polypropylene (BOPP)
　　O(导向):主要指生产过程。
　　O (orientation): mainly refers to the production process.
　　聚丙烯(PP)、聚丙烯，但作为一般结构件，耐腐蚀化工设备备件，电加热绝缘
　　Polypropylene (PP), polypropylene, but as general structural parts, corrosion resistant chemical equipment spare parts, electrical heating insulation
　　具有高透明度等特征,易碎,OPP单片折叠侧封边后,嘴里的舌头贴胶贴纸,在产品使用时撕保护皮肤表面的用舌头折叠后水泥密封,使用方便,美观大方,广泛应用于服装、食品、印刷、文具、化妆品、造纸等行业。还可根据客户需要打印各种图案并打蝴蝶洞、飞机洞。
　　With high transparency and fragility, the tongue stickers in the mouth after folding side seals of OPP single sheet can be used to tear and protect the skin surface. The cement seals after folding tongue are easy to use, beautiful and generous. They are widely used in clothing, food, printing, stationery, cosmetics, paper making and other industries. It can also print various patterns and punch butterfly holes and aircraft holes according to customers'needs.
　　OPP袋有明显的优势:
　　OPP bags have obvious advantages:
　　1. 好紧张。实验数据表明，新型OPP袋的密封性是传统袋的两倍以上，使产品更加保湿、保鲜、保鲜时间更长。
　　1. How nervous. The experimental data show that the sealing property of the new OPP bag is more than twice that of the traditional bag, which makes the product more moisturizing, fresh-keeping and fresh-keeping for longer time.

　　第二,强大的。所采用的合成技术和特种印刷技术具有较高的科技含量。目前，只有德国和日本掌握了这项技术，几乎不可能制造仿冒品，这为商品的防伪提供了有力的保障。

　　Second, strong security. The synthetic technology and special printing technology adopted have high scientific and technological content. At present, only Germany and Japan have mastered this technology, and it is almost impossible to manufacture counterfeits, which provides a strong guarantee for the anti-counterfeiting of commodities.
　　三世。新型OPP袋采用可降解材料制成，在环保方面完全符合相关国际标准。
　　III. The new OPP bags are made of degradable materials and fully meet the relevant international standards in environmental protection.
　　PE是聚乙烯的简称，是由乙烯聚合而成的热塑性树脂。在工业上，它还包括乙烯共聚物与少量的-烯烃。
　　PE is the abbreviation of polyethylene, which is a thermoplastic resin formed by the polymerization of ethylene. In industry, it also includes ethylene copolymers and small amounts of olefins.
　　聚乙烯无味,,感觉像蜡,具有优良的耐低温(低使用温度可达-70 ~ -100℃),化学稳定性好,可以承受酸和碱侵蚀(不是抗氧化性质的酸),常温下不溶于一般溶剂,吸水性小,优良的电气绝缘性能;但聚乙烯对环境应力(化学和机械效应)非常敏感，抗老化能力差。聚乙烯的性能因品种而异，主要取决于分子结构和密度。采用不同的生产方法可以得到不同密度(0.91 ~ 0.96g/cm3)的产品。聚乙烯可以用普通的热塑性成型方法加工(见塑料加工)。
　　Polyethylene is odorless, non-toxic, wax-like, has excellent low temperature resistance (minimum operating temperature can reach - 70 ~100 C), good chemical stability, can withstand the most acid and alkali erosion (not anti-oxidant acid), insoluble in general solvents at room temperature, low water absorption, excellent electrical insulation performance; but polyethylene has environmental stress (chemical and mechanical effects). It is very sensitive and has poor anti-aging ability. The properties of polyethylene vary according to its variety, mainly depending on its molecular structure and density. The products with different densities (0.91-0.96g/cm3) can be obtained by different production methods. Polyethylene can be processed by ordinary thermoplastic forming methods (see plastic processing).
　　另外，PE保鲜膜也可称为PE袋，注意与食品直接接触的保鲜膜必须选用PE材料(一般PVC除外)，对人体相对。
　　In addition, PE fresh-keeping film can also be called PE bag. Pay attention to the fact that PE material (except PVC) must be used for fresh-keeping film in direct contact with food, which is relatively safe for human body.
　　分辨率:PVC膜透明度、拉伸性和粘度均优于PE膜。PVC塑料薄膜在火灾中，火焰变黑，冒烟，有刺鼻的气味，不会滴油，留下的火会自动熄灭。PE薄膜燃烧时火焰呈黄色，无味，会滴油，而留下的火源可以继续燃烧。
　　Resolution: PVC film is superior to PE film in transparency, tensile property and viscosity. PVC plastic film in the fire, the flame blackened, smoking, has a pungent smell, will not drip oil, leaving the fire will automatically extinguish
