OPP袋和PE袋的鮮明優點！

OPP袋和PE袋的鮮明優點！

OPP袋是一種可拉伸的聚丙烯塑料，實際上是一種塑料袋，其特點是易于燃燒?；鹧媲闆r:熔融滴落，黃色下有藍色，從火中冒出較少煙霧后，繼續燃燒。
　　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)，是聚丙烯的一種類型和雙向聚丙烯(BOPP)
　　Oriented polypropylene (OPP): Oriented polypropylene (film), a type of polypropylene and bidirectional polypropylene (BOPP)
　　O(導向):主要指生產過程。
　　O (orientation): mainly refers to the production process.
　　聚丙烯(PP)、聚丙烯，但作為一般結構件，耐腐蝕化工設備備件，電加熱絕緣
　　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單片折疊側封邊后,嘴里的舌頭貼膠貼紙,在產品使用時撕保護皮膚表面的用舌頭折疊后水泥密封,使用方便,美觀大方,廣泛應用于服裝、食品、印刷、文具、化妝品、造紙等行業。還可根據客戶需要打印各種圖案并打蝴蝶洞、飛機洞。
　　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袋有明顯的優勢:
　　OPP bags have obvious advantages:
　　1. 好緊張。實驗數據表明，新型OPP袋的密封性是傳統袋的兩倍以上，使產品更加保濕、保鮮、保鮮時間更長。
　　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,強大的安全。所采用的合成技術和特種印刷技術具有較高的科技含量。目前，只有德國和日本掌握了這項技術，幾乎不可能制造仿冒品，這為商品的防偽提供了有力的保障。

　　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，在環保方面完全符合相關國際標準。
　　III. The new OPP bags are made of degradable materials and fully meet the relevant international standards in environmental protection.
　　PE是聚乙烯的簡稱，是由乙烯聚合而成的熱塑性樹脂。在工業上，它還包括乙烯共聚物與少量的-烯烴。
　　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.
　　聚乙烯無味,無毒,感覺像蠟,具有優良的耐低溫(低使用溫度可達-70 ~ -100℃),化學穩定性好,可以承受酸和堿侵蝕(不是抗氧化性質的酸),常溫下不溶于一般溶劑,吸水性小,優良的電氣絕緣性能;但聚乙烯對環境應力(化學和機械效應)非常敏感，抗老化能力差。聚乙烯的性能因品種而異，主要取決于分子結構和密度。采用不同的生產方法可以得到不同密度(0.91 ~ 0.96g/cm3)的產品。聚乙烯可以用普通的熱塑性成型方法加工(見塑料加工)。
　　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保鮮膜也可稱為PE袋，注意與食品直接接觸的保鮮膜必須選用PE材料(一般PVC除外)，對人體相對安全。
　　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、拉伸性和粘度均優于PE膜。PVC塑料薄膜在火災中，火焰變黑，冒煙，有刺鼻的氣味，不會滴油，留下的火會自動熄滅。PE薄膜燃燒時火焰呈黃色，無味，會滴油，而留下的火源可以繼續燃燒。
　　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
