"Micro perforated bags" means microporous breathable bags, which have many important functions:
1. Food preservation
Fruits and vegetables: Fruits and vegetables will breathe during storage, consume oxygen and release carbon dioxide. The tiny holes in the microporous breathable bags allow oxygen to enter the bag and discharge carbon dioxide at the same time, thereby ensuring the normal exchange of gas in the bag and delaying the aging and deterioration of fruits and vegetables. For example, apples and strawberries can be packaged in microporous breathable bags. The shelf life can be significantly extended.
Baked goods: Bread, cakes and other baked goods will produce water vapor during the cooling process. If water vapor accumulates in the packaging bag, it will make the food moist, affecting the taste and shelf life. Microporous breathable bags can allow water vapor to be discharged, keep the food dry, and keep the baked goods fresh and soft for a long time.
2. Prevent condensation water from forming
When the temperature of the items in the package is different from the external environment temperature, condensation water is easy to form in the packaging bag. The presence of condensation water may cause the product to become damp and moldy, affecting the product quality. Microporous breathable bags can balance the humidity inside and outside the bag, reduce the generation of condensation, and protect the product from moisture. For example, in the packaging of refrigerated foods, microporous breathable bags can effectively avoid the impact of condensation on food.
3. Keep products dry
For some products that are easily affected by moisture, such as grains, nuts, dry goods, etc., microporous breathable bags can allow air to circulate in the bag, take away excess moisture, and keep the product dry. This helps prevent the product from getting moldy and deteriorating, and extends the shelf life of the product.
4. Gas exchange
In some packaging that requires a specific gas environment, microporous breathable bags can achieve slow gas exchange. For example, in some fresh-keeping packaging, it may be necessary to control the concentration of oxygen and carbon dioxide in the bag. Microporous breathable bags can adjust the in and out of gas through tiny holes, maintain a suitable gas environment in the bag, and better preserve the product.
5. Avoid odor accumulation
For some products that produce odors, such as spices, tea, etc., microporous breathable bags can allow odors to dissipate, avoiding odors from accumulating in the bag and affecting the quality and taste of the product. At the same time, it can also prevent odor from affecting the surrounding environment and other products.
