Food manufacturers like to use them, so manufacturers of compostable zipper bags are also constantly innovating. So, why are zipper bags so popular? Let’s find out the reason together!

2. What products are zipper bags suitable for?
①Products with large quantities
When the product quantity exceeds the demand for a single consumption, such as large packages of dried fruits, nuts, etc. (usually 100-200g, or even 500-1000g for family packaging), zipper packaging bags become the ideal choice. This type of packaging allows users to easily reseal after initial opening, ensuring that remaining food remains fresh for subsequent storage and retrieval.

②Products that need to be kept dry at all times
Air-dried ingredients such as spices, aniseed, dried fungus, and dried mushrooms need to be kept dry for a long time to prevent them from deteriorating, so zipper bags become their ideal storage companion. It can quickly reseal the remaining ingredients and effectively isolate moisture. It is convenient and practical to ensure the freshness and quality of the ingredients.

③Products that require insect protection
Sweets such as candies and preserves, once the packaging bag is opened and not resealed, can easily attract ants and other insects, causing the food in the package to be quickly contaminated, affecting food safety. The use of zipper packaging bags can quickly seal remaining food and effectively prevent such problems from occurring.
