Heat-sealable metallized BOPP (biaxially oriented polypropylene) film is a specialized packaging material used in the food, beverage, and consumer goods industries. It is made by depositing a thin layer of aluminum onto a BOPP film, which provides a barrier to oxygen, moisture, and light, helping to extend the shelf life of the packaged product.
The heat-sealable property of the film refers to its ability to be sealed using heat, which creates a strong and durable seal between the layers of packaging material. This is typically done using heat sealing equipment, such as a hot jaw sealer, which melts the polymer layer of the film to create a bond between the layers.
The metallized layer of the film provides a decorative and reflective surface, which can be printed with high-quality graphics and branding. The film is also lightweight and flexible, making it easy to handle and package.
Overall, heat-sealable metallized BOPP film is a versatile and effective packaging material that provides excellent barrier properties and a high-quality appearance. It is commonly used for products such as snack foods, coffee, tea, and pet food, where extended shelf life and visual appeal are important factors.
