Dog food packaging bags come in a variety of options, including open type, vacuum packaging type, and aluminum foil packaging type, which are suitable for short-term and long-term storage respectively. Different bag types are suitable for different scenarios. Aluminum foil pet food packaging bags are a relatively high-cost pet food packaging bag. Its advantages are good sealing performance, moisture-proof, anti-corrosion, and easy to open. This kind of packaging bag is generally made of aluminum foil material. It has a beautiful appearance and is very suitable for high-end products. However, due to the high cost of aluminum foil materials, the price of such packaging bags is high. Vacuum pet food packaging bag is a special kind of pet food packaging bag. Its advantage is that it can effectively extend the shelf life of the product. This kind of packaging bag is generally made of composite materials. Common materials include PET/PE, BOPP/PE, etc.During the production process, the pet food is put into the packaging bag, and then the air in the packaging bag is extracted so that the packaging bag is tightly attached to the pet food, thereby achieving the effect of extending the shelf life. Since the cost of this kind of packaging bag is relatively high, it is generally used for higher-end products. When selecting dog food packaging, factors such as food characteristics, storage time, and usage should be considered to ensure food safety and hygiene. Common bag types include three-side sealing, four-side sealing, eight-side sealing, stand-up bags and special-shaped bags, etc. Currently, the commonly used materials are: PET/VMPET/PE or PET/PA/PE and PET/etc.
