Shrink Bag

Shrink Bag is a type of plastic packaging bag that shrinks and tightly wraps products when heated, typically made from materials such as PE, PVC, and POF. In foreign trade, it is commonly used for the protection, moisture-proofing, dust-proofing, and aesthetic display of export goods, especially suitable for electronic products, hardware tools, toys, stationery, daily necessities, etc. Usage scenarios include: factory packaging, container transportation, cross-border e-commerce retail packaging, etc. Precautions: Select appropriate specifications based on product size to avoid uneven shrinkage or breakage; pay attention to the shrinkage temperature and environmental requirements of different materials (such as EU REACH, RoHS); if used for food contact, it must comply with FDA or LFGB standards. The difference from ordinary plastic bags is that shrink bags have heat shrinkability and can conform to the product shape; the difference from vacuum bags is that shrink bags do not vacuum, only shrink through heating. In foreign trade documents, material, thickness, size, and shrinkage rate are often specified.
