Analysis on the use of outer coating film and inner coating film packaging bags
1. Definition

Outer-coated film packaging bags and inner-coated film packaging bags are two common structural forms of plastic packaging bags. The outer-coated film packaging bag is coated with a layer of film on the outside of the packaging bag, while the inner-coated film packaging bag is a layer of film on the inside of the packaging bag.
2. Purpose
1. Outer-coated film packaging bags: Outer-coated film packaging bags are mainly used for packaging high-end products such as cosmetics, pharmaceuticals, and food. The external coating film can protect the product, enhance the aesthetics, etc., and can effectively increase the added value of the product.
2. Inner-coated film packaging bags: Inner-coated film packaging bags are mainly used for packaging chemical raw materials, pesticides and other chemicals. The inner coating film can effectively prevent the chemicals in the packaging bag from directly contacting the packaging bag, preventing chemical reactions from causing gas leakage or sticking to the packaging bag.
