Plastic bags have become an indispensable package for people's daily shopping because of their light weight, but when we look at this variety of plastic bags, have you ever thought about what materials they are made of, each material What is the difference between plastic bags? Today we will talk about the difference between PP bags and PE bags.

 

The so-called PP bag is a plastic bag made of polypropylene. It is generally made of color printing, offset printing process, bright color, generally more woven bags, and PP bag is a stretchable polypropylene plastic, which belongs to thermoplastics. Kind. It is non-toxic, tasteless and has a smooth and transparent surface. It is easy to burn, the flame condition is melt dripping, yellow on the blue, less smoke after the fire, continue to burn, and is used in the packaging of cosmetics, food, toys, clothing, stationery, electronics, hardware and other industries. The color is transparent, the quality is good, and the toughness is good. Because of its hard and brittle material, it is only suitable for packaging and is not suitable for bearing.

 

The so-called PE bag is a plastic bag made of polyethylene. Polyethylene is recognized as the best material for food contact in the world. Non-toxic, odorless, odorless, feels like wax, in line with food packaging hygiene standards. Polyethylene film, light and transparent, with moisture, oxygen, acid, alkali, air tightness, heat sealing and other properties, known as the "plastic flower", is the most used plastic packaging printing, the most important material. In addition, polyethylene can be classified into LDPE (low density high pressure polyethylene), LLDPE and HDPE (high density low pressure polyethylene). Among them, low-density polyethylene is the most widely used in the plastic packaging and printing industry in various countries. It is suitable for food packaging, fiber packaging, and daily chemical packaging. High-density polyethylene heat-resistant and steam-resistant, cold-resistant and freeze-resistant, moisture-proof and gas-proof. Good insulation performance, good ductility and not easy to break.Plastic bags have become an indispensable package for people's daily shopping because of their light weight, but when we look at this variety of plastic bags, have you ever thought about what materials they are made of, each material What is the difference between plastic bags?
