Wrapping shrinking machines can shrink and tightly adhere the film to the product surface by heating, forming a transparent and sturdy protective film. Wrapping shrinking machine can automatically complete the processes of wrapping, sealing, cutting, heating (film shrinking), colling (setting), and output.

Wrapping shrinking machine is equipped with a heat-sealing knife to heat-seal the film longitudinally and laterally, and simultaneously cut the film to form a closed film bag. Depending on the material of the film, the temperature is set to ensure the uniformity and flatness of the wrapped product. When the film is headed to a certain temperature, its internal molecular chains undergo "memory recovery", generating a strong sharinking force that quickly shrinks and adheres tightly to the product surface. After heat shrinking the film reaches a very high temperature and is in a plastic state. The product then enters the cooling zone, where it can be cooled by a cold air fan or naturally, forming a sturdy and transparent package.

  Wrapping shrinking machines are widely used in the food, daily chemical, and electronics industries for products such as biscuit boxes, beverage bottles, toys, and shampoo bottles. A variety of heat-shrink films are available: POF, PVC, PP, PE, etc.
