PET: very high transparency, similar to glass, can clearly see the details of the food inside the bag, and the gloss is also very good.

Low-density polyethylene (LDPE): has good oil resistance. It has a relatively loose molecular structure and a certain degree of flexibility, which can resist the penetration of grease to a certain extent.

High-density polyethylene (HDPE): harder texture, high strength and toughness, wear resistance, corrosion resistance, poor permeability, can better maintain the odor of the garbage, commonly used in the production of thicker, larger garbage bags, such as industrial or household use of large garbage bags.

Polyethylene (PE) garbage bags: this is the most common material for garbage bags, and the price varies depending on the specific type, size, thickness and brand.

High density polyethylene (HDPE) garbage bags: HDPE material is tough and durable, not easy to break, with good water resistance and corrosion resistance.

The characteristics of different materials of garbage bags are different, and the application scenarios are also different, the following is a specific introduction:

The safety factors of supermarket food bags are crucial, and are analyzed below in terms of materials, additives, production processes, and hygiene standards:

Evaporated residue: The amount of evaporated residue of food bags in solvents such as acetic acid, ethanol and hexane needs to be tested.
