Butter Milk Pouch Film is made of LDPE (Low-Density Polythene). To prevent the wrinkles and air bubbles from forming in the seal, the film is held in the sealer for some time. Its straight-tear technology ensures clean and easy opening of the film. It protects milk from humidity, dust, and dirt and can be stored in a refrigerator, ice or water. Some additives are also added to make the film strong and resistant to UV and VCI (Volatile Corrosion Inhibitor).
