If impurities or moisture are mixed into the resin, local stress concentration points will be formed during the melting stage, resulting in bubbles of varying sizes during bubble wrap molding.

To improve the compression resistance of traditional express cartons, the number of cardboard layers or thickness is often increased, but this will significantly increase the weight of the packaging.
This structure not only ensures the cushioning efficiency, but also regulates the internal humidity through the breathable membrane, achieving a dynamic balance between moisture-proofing and cushioning.
The size design of express cartons needs to comprehensively consider the size of the contents, transportation stacking requirements, and the spatial form after folding.
The bubble structure of traditional bubble wrap easily forms a closed humid space, providing a breeding environment for mold.
In modern commodity distribution and consumer experience, packaging is no longer simply a protective layer during transportation; it has become a bridge of trust and connection between brands and users.
