What issues should be considered in the protection of goods by plastic packaging bags？

1. The protection function of plastic packaging bags for commodities is the most important and basic function, and the protection functions are multi-faceted. Different commodities need different packaging forms, so the requirements are different.

2. Welding strength

If the welding strength is insufficient, this will become the Achilles heel of the plastic packaging bag, and the plastic bag will lose its protective effect on the goods due to the rupture of the welding.

3. Other features

We also need to consider barrier properties and shading properties. For food commodities, the barrier properties of plastic packaging bags determine whether the commodities can be stored for a long time and prevent the entry of gases such as carbon dioxide. In addition, light-shielding properties can also prevent discoloration and fading of products.
