What kind of plastic bag is opp bag and the difference between opp bag and pe bag and pp bag
opp bag is a kind of plastic bag, opp refers to polypropylene, is one of the raw materials for making plastic. The plastic bags made of opp have the advantages of good sealing, anti-counterfeiting, biodegradable and environmentally friendly, and are widely used in jewellery, jade, stationery, toys, tableware, kitchen utensils, clothing and other fields. pp and pe are also two kinds of raw materials for making plastic, pp bags and opp bags have certain differences in terms of touch and transparency, the difference between opp bags and pe bags lies in the material, transparency and feel. Here to learn more about the three types of plastic bags, pp bags and pe bags material it!
What are opp bags made of?
opp bag is a plastic bag, the material is polypropylene, two-way polypropylene, its characteristics are easy to burn, molten drip, on the yellow under the blue, away from the fire less smoke, continue to burn. opp, the full name of the English name is Oriented polypropylene, oriented polypropylene film, is a kind of polypropylene as well as two-way polypropylene.
Opp bag is oriented oriented polypropylene film, opp bag transparency is the best, the highest, the most translucent, with the role of dust, improve the value of the packaged products. In sales can fully display the products inside, so OPP bags products are usually used for the sale of goods outside the packaging, both to play a protective role, but also play a beautifying role. Widely used in jewellery, jade, stationery, toys, tableware, kitchen utensils, clothing and other fields. However, OPP bags are brittle, toughness is not good enough, easy to tear, so the general use of adhesive paste form of closure, the product volume is relatively large or heavy weight, generally add explosion-proof edge to prevent cracking.
What are the advantages of opp bags?
1、Good sealing. Experimental data shows that the new OPP film is more than twice as airtight as its traditional counterpart, thus making its products more moisturizing and freshness preserving for a longer period of time.
2. Strong anti-counterfeiting properties. The new film uses synthetic technology and special printing technology with a high technological content, making counterfeit production almost impossible, providing a strong guarantee against counterfeiting of goods.
3. The raw materials used in the new OPP film are biodegradable materials and therefore fully comply with the relevant international standards in terms of environmental protection.
The difference between pp and pp bags
PP bags are made of polypropylene and made into plastic bags, which generally use color printing, offset printing process, bright colours, generally more woven bags, in addition PP bags are stretch polypropylene plastic, belongs to a thermoplastic plastic. PP bags and OPP bags have certain differences: 1, touch, OPP will seem more brittle, harder, and PP softness is better:
1、touch, OPP will seem more brittle, more hard, while PP softness is better.
2、transparency, OPP transparency is better, PP transparency is slightly worse, now some high permeability PP transparency can also be close to OPP.
The difference between opp bags and pe bags
pe bag is ethylene by polymerization of a thermoplastic resin made of plastic bags, has excellent low temperature resistance, good chemical stability, can resist the erosion of most acids and bases, mainly used to manufacture films, containers, pipes, monofilament, wire and cable, daily necessities, etc., and can be used as high-frequency insulation materials for television, radar, etc.. The difference between it and the opp bag is that
1、the material is different, PE is polyethylene, OPP is polypropylene.
2、transparency is different, PE bags are translucent, OPP bags are fully transparent.
3、the feel is not the same, PE bags are soft, tough, touch a little astringent feeling, OPP is more brittle, very smooth.
