  The flexible packaging material is a paper material treated with a high heat-sensitive coating.


  Flexible packaging, that is, the shape can be changed, is mainly composed of film, ink and adhesive, and their respective proportions can reach 70%, 20%, and 10%. Plastic flexible packaging has many advantages, such as light texture, convenient carrying, strong impact resistance, good barrier properties, easy printing, low cost, and can be used for microwave heating.
