Keep your fresh or leftover food healthy by sealing the container with 2.1 Kg Tite Wrap PVC cling film. PVC granules are used as a raw material in the production process, which starts with melting the granules, followed by bubble formation, rolling the bubble into plastic film. A large roll is formed in this process, which is then cut and rerolled in 2.1 Kg Tite Wrap PVC cling film roll. The film gets cling by the process of rolling and unrolling. If you do not have aluminium foil, you can use this film to double wrap the container for better insulation.
