What are the factors that affect the heat sealing strength of heat shrink film

The drying process of heat shrink film adhesive refers to the process of evaporating the solvent or moisture in the adhesive layer coated on the substrate to cure the adhesive. Due to the time required for solvents or water to evaporate, drying is a relatively slow step in the production process of protective films. The drying speed not only determines the production speed but also greatly affects the quality of the product.
