Many packaging boxes are wrapped with a layer of shrink film on the outside. Do you know what it's used for? Today, Leadmens Packaging will introduce to you. 

There are seven main functions:

1. Protection of products: shrink wrap can prevent external factors such as dust and moisture from damaging the packaging box and internal products, ensuring that the products remain intact during transportation and storage.

2. Enhance packaging strength: The shrink film adheres tightly to the packaging box, increasing overall strength and preventing deformation or damage during transportation.

3. Anti counterfeiting and anti-theft: Once the shrink film is damaged and difficult to restore, it can effectively prevent the product from being opened or exchanged, protecting consumer rights.

4. Enhance appearance: shrink wrap makes packaging flatter and more aesthetically pleasing, elevating product quality and making it particularly attractive in retail environments.

5. Fixed internal items: For multi piece or easily movable products, shrink wrap can fix internal items to prevent shaking or damage during transportation.

6. Easy to handle and stack: shrink wrap makes packaging more stable, easy to handle and stack, reducing accidental damage during transportation and storage.

7. Environmental Protection: Some shrink films are recyclable, reducing packaging waste and meeting environmental requirements.

In summary, shrink wrap not only enhances the protection and aesthetics of packaging, but also has anti-counterfeiting, anti-theft and other functions, enhancing the overall value of the product.
