Potato Chips Packaging Material
The potato chip packaging bags on the market are mostly composite materials made of biaxially oriented polypropylene film, low density polyethylene and aluminum foil. Among them, biaxially oriented polypropylene film is used as the outer layer material, because of its good printing adaptability, good gloss and moderate price. Aluminum foil is used as the inner material, which can play the role of moisture-proof.
Many potato chip manufacturers will require high barrier properties, high light protection, good oil resistance, and exquisite gravure printing when purchasing packaging materials. The usual structure is: BOPP/VMPET/PE、BOPP/VMPET/CPP、BOPP/VMPET/EX-PE/PE, etc.
Generally, the packaging material used for potato chips products is composite film packaging material, which is a combination of printing layer/aluminized barrier layer/heat sealing layer. It can be seen that the aluminum layer is not in direct contact with the food, and is usually in direct contact with some safer plastics. And food packaging, the products of regular enterprises must be certified for safety before they can be eaten with confidence.
