In the previous article, we introduced that sealing film consists of a surface layer, a middle layer, and an inner layer. We also explained its usage steps: feeding and filling, capping and induction sealing, instant sealing and cooling. Today, Leadtra Packaging will continue to introduce why sealing film is designed in this way? 

This design achieves multiple purposes: 

1. Absolute sealing: effectively prevents moisture, oxidation, leakage, and extends shelf life. 

2. Anti counterfeiting and anti-theft: Once torn, it cannot be restored, which is a strong proof that the product has not been opened. 

3. Efficient and safe: The entire process does not require open flames or direct contact, with fast speed and high hygiene level. 

What does this mean for consumers? 

As a consumer, simply tear off this layer of film to enjoy the security it brings. And the next time you tear it open with a 'stab' sound, you will know that behind it is a sophisticated and reliable industrial automation process guarding the quality and safety of the product.
