Compound packaging film bags are made of several layers of oil. When customizing food packaging film bags, customers often need to provide the packaging material structure or suggest it by the soft package factory. So what are the requirements for the material of food packaging film bags? Here we will introduce the material structure and requirements of several common food packaging.
Cooking bags
product requirement:
It is used for packaging of meat and poultry, etc. It is required to have good barrier property, resistance to bone hole breakage, sterilization under cooking conditions, no breakage, cracking, shrinkage and no odor.
Design structure:
Transparent: BOPA / CPP , PET / CPP , PET / BOPA / CPP , BOPA / PVDC / CPP , PET / PVDC / CPP , GL-PET / BOPA / CPP
Aluminum foil: PET / AL / CPP , PA / AL / CPP , PET / PA / AL / CPP , PET / AL / PA / CPP
Choose the appropriate structure for the specific product, transparent bags are mostly used for cooking, AL foil bags can be used for ultra-high temperature cooking.
Miso packaging bag
product requirement:
Odorless and tasteless, low temperature sealing, anti-sealing pollution, good barrier properties, and moderate price.
Design structure:
KPA / S-PE
Design reasons:
KPA has excellent barrier property, good toughness, high compound fastness with PE , easy to break the package, and good printability. Modified PE is a blend of multiple PEs (coextrusion), with low heat sealing temperature and strong resistance to sealing pollution.
Cooking oil
product requirement:
Anti-oxidative deterioration, good mechanical strength, high burst strength, high tear strength, oil resistance, high gloss and transparency.
Design structure:
PET / AD / PA / AD / PE , PET / PE , PE / EVA / PVDC / EVA / PE , PE / PEPE
Design reasons:
PA , PET and PVDC have good oil resistance and high barrier property. PA , PET and PE have high strength, and the inner PE is special PE , which has good sealing pollution resistance and high airtightness.
Milk film
product requirement:
Good barrier property, high burst strength, light protection, good heat sealability and moderate price.
Design structure:
White PE / White PE / Black PE
Design reasons:
The outer layer PE has good gloss and high mechanical strength, the middle layer PE is the strength bearer, and the inner layer is the heat seal layer, which has the properties of light protection, barrier and heat seal.
Beverage packaging bag
product requirement:
Acidic beverages have a PH value of <4.5 , pasteurized, and generally barrier.
Neutral beverages with a PH value > 4.5 are sterilized and have high barrier properties.
Design structure:
Acidic beverages: PET / PE ( CPP ), BOPA / PE ( CPP ), PET / VMPET / PE
Neutral beverages: PET / AL / CPP , PET / AL / PA / CPP , PET / AL / PET / CPP , PA / AL / CPP
Design reasons:
For acidic beverages, PET and PA can provide good barrier properties and pasteurization resistance, because the acidity extends the shelf life. For neutral beverages, AL provides the best barrier properties, high strength PET , PA , high temperature sterilization.
Soy sauce, sauce
product requirement:
Requires high strength, long shelf life, anti-oxidation, corrosion resistance, and good pit sealing pollution.
Design structure:
KPA / LLDPE . EVA , BOPA / VMPET / LLDPE . EVA , PET / AL / PET / LLDPE . EVA , PET / VMPET / LLDPE . EVA .
Design reasons:
KOP , AL , and VMPET are all high-barrier materials with excellent oxygen and water resistance. The AL layer is properly kept away from the inner layer to prevent corrosion, LLDPE . EVA has good anti-sealing pollution.
