Custom Printed Back Seal Pillow Bag Snack Potato Chips


otato chips are a type of food that is very fragile, if simply placed in plastic packaging bags, after rough transportation and shelving, they will end up as a bag of crumbs in the hands of customers.In order to prevent this situation from occurring, manufacturers inject a large amount of nitrogen gas into the packaging bag, also known as the "gas filling packaging bag method". This helps to create a protective atmosphere inside the bag, reducing the risk of oxidation and spoilage of the product. By using this method, the shelf life of the product can be extended and the quality can be better maintained during storage and transportation. This technique is commonly used in the food industry for products such as snacks, dried fruits, and processed meats.No matter how rough the transportation process is, or how crowded the storage is, the nitrogen-filled potato chip bags will not be easily crushed. In other words, the gas-filled packaging bags serve as a cushion and protection. Filling nitrogen can prevent potato chips from becoming moist and oxidized. This is mainly because nitrogen is chemically inert and is commonly used as a protective gas.
