Polypropylene bags combine excellent chemical resistance and strength. Unlike LDPE or LLDPE bags, polypropylene bags are not breathable, resulting in longer product shelf life for retail situations. Items like herbs, nuts, candies, and other confectioneries are perfect for storing in PP bags. Additionally, polypropylene bags are clearer than LDPE or LLDPE bags for enhanced product visibility. PP bags also have a high melting point, meaning they are great for heat sealing, and, similar to the other plastic food bag options, they are FDA/USDA approved.

Physical and mechanical properties of packaging bags
The processing of plastic film bags must go through the heating process. When the plastics are heated, there are problems such as cracking, oxidation, degradation and deterioration, etc. Therefore, when the plastic film or plastic bags are treated with resin, additives such as antioxidant and heat stabilizer must be added to the resin.Because some packaging technology and packaging machinery or contents require anti-static, anti-condensation, high gloss, so also added anti-static agents, antifogging agents, lubricants and other opening agents.All these additives must be tested by the food safety toxicology evaluation procedure (GB15139) to prove that they are non-toxic, but the content of additives is limited.Accordingly, in the product, these can extract low molecular weight material, namely evaporative residue, or the material that can oxidize metamorphism, namely the consumption of potassium permanganate, cannot exceed the specified amount, exceed the use range.Therefore, the injection products should be formulated with appropriate hygienic standards, with the aim of preventing misuse and abuse of additives, and better ensuring direct packaging and cont
