OPP袋是什么材质的塑料袋?

OPP袋子是拉伸性的聚丙烯，属于塑料的一种，其实就是塑料袋，在市场上随处可见，一般透明包装袋大部分都是OPP材料做的，这种材料印刷方便，性能也好，现在用得广。其特征是：容易燃烧，火焰情况：熔融滴落，上黄下蓝，离火后烟少，继续燃烧。

OPP bags are stretchable polypropylene, a type of plastic that can be seen everywhere in the market. Generally, transparent packaging bags are mostly made of OPP material, which is easy to print and has good performance. It is now the most widely used material. Its characteristics are: easy to burn, flame situation: molten droplets, yellow on top and blue on the bottom, less smoke after leaving the fire, continuing to burn.

是一种透明、厚度均匀、质感柔韧、具有较好的耐水性、耐温性和封口性的塑料袋。OPP袋的生产原材料是聚丙烯，通过特殊的拉伸工艺，使聚丙烯分子在纵向和横向上排列有序，从而使袋子的透明度、拉伸强度、抗撕裂性和耐磨性等性能得到提高。OPP袋广泛应用于食品、饮料、日用品、药品、化妆品、服装、文具、礼品等各个领域的包装中，是一种经济实用的包装材料。

It is a plastic bag that is transparent, uniform in thickness, flexible in texture, and has good water resistance, temperature resistance, and sealing properties. The raw material for producing OPP bags is polypropylene. Through a special stretching process, polypropylene molecules are arranged in an orderly manner in both longitudinal and transverse directions, thereby improving the transparency, tensile strength, tear resistance, and wear resistance of the bags. OPP bags are widely used in packaging in various fields such as food, beverages, daily necessities, pharmaceuticals, cosmetics, clothing, stationery, gifts, etc. They are an economical and practical packaging material.

但OPP袋比较脆，韧性不够好，容易撕破，故一般采用粘胶贴的形式封口，产品体积比较大或重量比较重的，一般加防爆边，防止开裂。

However, OPP bags are relatively brittle, have poor toughness, and are prone to tearing, so they are generally sealed with adhesive tape. For products with large volume or heavy weight, explosion-proof edges are generally added to prevent cracking.

opp袋有什么优点

What are the advantages of OPP bags

1、密封性好。实验数据表明，新型OPP膜的密封性是其传统膜的一倍以上，从而使其产品的保湿、保鲜性更强，保存时间更长。

1. Good sealing performance. The experimental data shows that the sealing performance of the new OPP film is more than twice that of its traditional film, which makes its products more moisturizing and fresh-keeping, and has a longer storage time.

2、防伪性强。新膜使用的合成技术和特殊的印刷技术具有很高的科技含量，仿冒制作几无可能，为商品防伪提供了有力保证。

2. Strong anti-counterfeiting ability. The synthesis technology and special printing technology used in the new film have high technological content, making it almost impossible to counterfeit, providing strong guarantees for anti-counterfeiting of goods.

3、新型的OPP膜所使用的原料为可降解材料，故在环境保护方面完全符合国际相关标准。

3. The raw materials used in the new OPP membrane are biodegradable materials, which fully comply with international standards in terms of environmental protection.

OPP袋和PE袋的区别

The difference between OPP bags and PE bags

PE袋是乙烯经聚合制得的一种热塑性树脂制成的塑料袋，具有优良的耐低温性能，化学稳定性好，能耐大多数酸碱的侵蚀，主要用来制造薄膜、容器、管道、单丝、电线电缆、日用品等，并可作为电视、雷达等的高频绝缘材料。它和opp袋的区别在于：

PE bag is a plastic bag made of thermoplastic resin polymerized from ethylene, which has excellent low-temperature resistance, good chemical stability, and can withstand most acid and alkali corrosion. It is mainly used to manufacture films, containers, pipelines, monofilaments, wires and cables, daily necessities, and can also be used as high-frequency insulation materials for televisions, radars, etc. The difference between it and OPP bag is:

1、材质不同，PE是聚乙烯，OPP是聚丙烯。

1. The materials are different, PE is polyethylene, and OPP is polypropylene.

2、透明度不同，PE袋是半透明的，OPP袋是全透明的。

2. The transparency is different. PE bags are semi transparent, while OPP bags are fully transparent.

3、手感不一样，PE袋比较柔软，有韧性，摸起来有点涩涩的感觉，OPP比较脆，很光滑。

3. The feel is different, PE bags are relatively soft and resilient, with a slightly astringent feeling to the touch, while OPP is relatively brittle and smooth.
