The difference between transparent OPP bags and transparent PE bags

The difference between transparent OPP bags and transparent PE bags

As we all know, plastic bags can be made of different materials and are widely used in the packaging field on the market. The two most common bags are OPP bags and PE bags. The main difference between OPP bags and PE bags lies in their materials. Let's analyze the difference between transparent OPP bags and transparent PE bags.

There is a big difference in appearance between transparent OPP bags and transparent PE bags. OPP bags are usually relatively transparent and shiny. PE bags are relatively dull and not very shiny. The transparency of OPP bags will also be slightly higher than PE bags. This is also an important reason why OPP bags are more popular than PE bags in the market.

The materials of OPP bags and PE bags are also different. OPP bags are made of polypropylene, while PE bags are made of polyethylene. OPP bags made of polypropylene have high toughness, strong tensile resistance and wear resistance. In contrast, PE bags made of polyethylene are slightly brittle and easy to tear. The technical indicators of OPP bags and PE bags are also different. The OPP bag feels relatively hard and has good moisture-proof and waterproof capabilities. Because the material of OPP bags is relatively hard and has a certain pressure resistance, it can be used to pack some heavier items. The vertical pressure test value of PE bags is relatively low, but it performs better in terms of flexibility and thermal insulation. Therefore, PE bags are more suitable for packaging insulation materials or liquids. OPP bags and PE bags also have different uses. OPP bags are usually used to package exquisite gifts, stationery, candies, biscuits, etc. Because OPP bags have high transparency and good gloss, ensuring the visibility and beauty of items in the packaging. PE bags are mainly used for packaging food, medicine, cosmetics, etc. Because PE bags have good flexibility and waterproof and moisture-proof properties, they are more suitable for storing food and medicine.

Therefore, there is a big difference between transparent OPP bags and transparent PE bags. From the perspective of appearance, materials, indicators and uses, each has its own applicable scope. When we choose to buy, we must choose according to our own needs, so that we can better meet our needs.
