    The color of the plastic film is an essential aspect of the packaging. Each color has its own specific use. The color you choose will depend on the company’s needs, the type of products packed, and the environments in which these products are stored or transported.

    Transparent film

    This is particularly useful for identifying packaged products. In a warehousing or production environment, transparency means you can quickly see which products are contained on pallets without having to remove the film. This improves efficiency and inventory management.

    Black film

    This provides effective protection against light. It is therefore used to protect light-sensitive products (photosensitive materials, chemicals). In addition, black plastic film offers a degree of privacy, as it conceals the pallet’s contents.

    White film

    This is similar to black film in terms of light protection. It has the added advantage of effectively protecting products from UV rays. This feature is important for products that could be damaged by prolonged exposure to the sun.

    Translucent blue film

    This film is commonly used in food packaging. The color blue is often associated with freshness and food safety, making it a popular choice for products intended for human consumption.

    Other plastic film colors can be used to help identify products in a storage environment, allowing them to be distinguished at a glance and saving time during order picking. Red, for example, is one of these colors.
