Unlike heat-sealing films, cold-sealing films do not require a heat source to achieve sealing. This film is usually composed of PET/BOPP material and a heat-sensitive adhesive layer, and relies on pressure and cooling to achieve the sealing effect. Cold-sealing films are often used to seal products such as candy, beverages, and cosmetics. Compared with heat-sealing films, cold-sealing films provide better protection for products.
