What Are The Differences Between OPP Bags And PE Bags

The main difference between OPP bags and PE bags lies in their materials and properties: OPP bags are made of polypropylene, which is relatively brittle, highly transparent, and smooth to the touch, but has weaker puncture resistance; PE bags are made of polyethylene, which is flexible, tear-resistant, and mostly translucent or milky white, with a soft feel. OPP bags are more suitable for retail packaging where appearance is important, such as gifts and cosmetics; PE bags are mostly used in scenarios where high flexibility is required, such as logistics liners and supermarket vest bags. In addition, OPP bags have better moisture resistance, while PE bags are more leak-proof and have stronger low-temperature resistance.
