Shrink Packaging

Shrink packaging is a packaging method that uses heat-shrinkable film to wrap a product, then applies heat to make the film shrink tightly around the product surface. In foreign trade, it is commonly used to protect goods, prevent moisture and dust, secure products, and enhance display appeal. Use cases include: retail packaging for individual items (such as electronics, toys, books), and collective packaging for palletized goods (such as shrinking multiple cartons into one unit). Precautions: select appropriate material (such as PE, PVC, POF) based on product characteristics, and ensure proper shrinkage temperature and time to avoid damaging the product; for food or pharmaceuticals, it must comply with the importing country's hygiene standards. Unlike ordinary stretch wrapping, shrink packaging film clings tightly to the product, providing tighter fixation and a more attractive appearance; unlike vacuum packaging, shrink packaging does not create a vacuum and mainly relies on film shrinkage force for fixation. In foreign trade documents, the packaging method should be clearly stated to avoid customs clearance issues caused by packaging non-compliance.
