1. What is food-grade plastic box lining?
Food-grade plastic bag box lining is an inner packaging bag specially used for fruit transportation and storage. It is made of food contact safety materials such as PE (polyethylene), PP (polypropylene) or PA/PE co-extruded film, meets FDA or EU food safety standards, and can directly contact fruits to ensure that no harmful substances migrate.
2. Typical application scenarios in fruits
Fruit protection after picking: lay the plastic lining in the plastic basket or carton to prevent the fruit from direct contact with the box body to avoid scratches or collisions.
Inner bags for export packaging: Fruit exports often require cold chain transportation, and the lining bags can prevent moisture and odor penetration, keeping the fruit original and clean.
Supermarket turnover and distribution use: The lining bags are convenient for maintaining fruit hygiene during turnover and reducing pollution and loss during multiple handling.
Fresh e-commerce packaging: used as sub-packaging bags or isolation inner bags to improve the hygienic experience of consumers receiving goods.
