OPP袋是什么材質(zhì)的塑料袋?

OPP袋子是拉伸性的聚丙烯，屬于塑料的一種，其實(shí)就是塑料袋，在市場(chǎng)上隨處可見，一般透明包裝袋大部分都是OPP材料做的，這種材料印刷方便，性能也好，現(xiàn)在用得廣。其特征是：容易燃燒，火焰情況：熔融滴落，上黃下藍(lán)，離火后煙少，繼續(xù)燃燒。

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.

是一種透明、厚度均勻、質(zhì)感柔韌、具有較好的耐水性、耐溫性和封口性的塑料袋。OPP袋的生產(chǎn)原材料是聚丙烯，通過特殊的拉伸工藝，使聚丙烯分子在縱向和橫向上排列有序，從而使袋子的透明度、拉伸強(qiáng)度、抗撕裂性和耐磨性等性能得到提高。OPP袋廣泛應(yīng)用于食品、飲料、日用品、藥品、化妝品、服裝、文具、禮品等各個(gè)領(lǐng)域的包裝中，是一種經(jīng)濟(jì)實(shí)用的包裝材料。

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袋比較脆，韌性不夠好，容易撕破，故一般采用粘膠貼的形式封口，產(chǎn)品體積比較大或重量比較重的，一般加防爆邊，防止開裂。

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袋有什么優(yōu)點(diǎn)

What are the advantages of OPP bags

1、密封性好。實(shí)驗(yàn)數(shù)據(jù)表明，新型OPP膜的密封性是其傳統(tǒng)膜的一倍以上，從而使其產(chǎn)品的保濕、保鮮性更強(qiáng)，保存時(shí)間更長。

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、防偽性強(qiáng)。新膜使用的合成技術(shù)和特殊的印刷技術(shù)具有很高的科技含量，仿冒制作幾無可能，為商品防偽提供了有力保證。

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膜所使用的原料為可降解材料，故在環(huán)境保護(hù)方面完全符合國際相關(guān)標(biāo)準(zhǔn)。

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袋的區(qū)別

The difference between OPP bags and PE bags

PE袋是乙烯經(jīng)聚合制得的一種熱塑性樹脂制成的塑料袋，具有優(yōu)良的耐低溫性能，化學(xué)穩(wěn)定性好，能耐大多數(shù)酸堿的侵蝕，主要用來制造薄膜、容器、管道、單絲、電線電纜、日用品等，并可作為電視、雷達(dá)等的高頻絕緣材料。它和opp袋的區(qū)別在于：

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、材質(zhì)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、手感不一樣，PE袋比較柔軟，有韌性，摸起來有點(diǎn)澀澀的感覺，OPP比較脆，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.
