Customizing knowledge of plastic shopping bags
Generally, the varieties of customized plastic bags are supermarket shopping bags, clothing handbags, Vest Bags, food bags, etc. Although they are collectively referred to as plastic bags, their material quality is different.
Differences in plastic shopping bag materials: 1. Low pressure polyethylene material: it has good tension and hardness, and has bright color. It is mainly used for making supermarket vest bags, customized shopping bags, etc. 2. High pressure polyethylene material: it is relatively soft, smooth in surface, strong in flexibility and brighter in color than low pressure materials. It is the first choice for most clothing bags and gift bags. The grade of customized plastic bags is generally higher than that of low pressure film materials. 3. PVC material: it has high strength, corrosion resistance and non flammability, but in order to enhance the heat resistance, toughness and ductility of plastic bags, plasticizers, stabilizers, anti-aging agents and other toxic auxiliary materials are added in the production process. Therefore, it is not suitable for food packaging, and is often used for cosmetic packaging and box packaging. 4. Polypropylene material: its density is small, strength and stiffness, hardness and heat resistance are better than those of low pressure material, but it is easy to crack, age and wear, so it is mostly used for clothing packaging and textile packaging.
