Different food according to the characteristics of food to choose the different material structure of food packaging bag, so what kind of food for what kind of material structure as a food packaging bag, today, professional flexible packaging manufacturers Soonseal source packaging to read for you, the need to customize food packaging bag customers can refer to.
1. High-temperature retort bag
Product requirements:
Used for meat, poultry, and another packaging, the packaging barrier is required to be good, undercooking conditions sterilization is not broken, not cracked, no shrinkage, no peculiar smell.
Design structure:
Transparent classes: 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
Reason:
PET: High-temperature resistance, good rigidity, good printing, high strength.
PA: high-temperature resistance, high strength, flexibility, good barrier, and puncture resistance.
AL: Best barrier, high-temperature resistance.
CPP: High-temperature cooking grade, good heat sealing, non-toxic and tasteless.
PVDC: High-temperature resistance barrier material.
Gl-pet: ceramic evaporation coating, good barrier, microwave penetration.
For specific products to choose the appropriate structure, transparent bags are mostly used for cooking, AL foil bags can be used for ultra-high temperature cooking.
2. Puffed snack food packaging bag
Product requirements: oxygen resistance, water resistance, light resistance, oil resistance, fragrance, appearance, bright color, low cost.
Design structure:
BOPP/VMCPP
Reason:
BOPP and VMCPP are pretty scraping, BOPP printing is good, high gloss. VMCPP barrier is good and retains moisture resistance. CPP also has better oil resistance.
3. Cookie wrap
Product requirements:
Good barrier, strong shading, oil resistance, high strength, odorless tasteless, packaging quite scraping.
Design structure:
BOPP/EXPE/VMPET/EXPE/S-CPP
Reason:
BOPP has good rigidity, good printability, and low cost. VMPET has a good barrier, light resistance, oxygen resistance, and water resistance. S-CPP has good heat sealing and oil resistance at low temperatures.
4. Milk powder bags
Product requirements:
Long shelf life, aroma, and taste, anti-oxidation metamorphism, anti-moisture caking.
Design structure:
BOPP/VMPET/S-PE
Reason:
BOPP has good printing, good gloss, good strength, and a moderate price.
VMPET has a good barrier, light protection, good toughness, and metallic luster. It is better to use enhanced PET aluminum plating and AL layer thickness. S-pe pollution-resistant sealing, low-temperature heat sealing.
5. Teabags
Product requirements:
Prevent spoilage, discoloration, and taste, which is to prevent the protein, chlorophyll, catechuic acid, and vitamin C oxidation contained in green tea.
Design structure:
BOPP/AL/PE, BOPP/VMPET/PE, KPET/PE
Reason:
AL foil, VMPET, and KPET are excellent barrier materials, good barriers to oxygen, water vapor, and odor. AK foil, VMPET light protection is also excellent. The product is moderately priced.
6. Grind coffee bags
Product requirements:
Anti-water absorption, anti-oxidation, resistance to hard blocks after vacuuming, keep the volatile and easily oxidized aroma of coffee.
Design structure:
PET/PE/AL/PE, PA/VMPET/PE
Reason:
AL, PA, VMPET good barrier, water resistance, gas resistance, PE heat sealing.
7. Chocolate bags
Product requirements:
Good barrier, avoid light, low-temperature heat sealing.
Design structure:
Pure chocolate varnish/ink/white BOPP/PVDC/ cold sealer.
Nut chocolate varnish/ink /VMPET/AD/BOPP/PVDC/ cold sealer.
Reason:
PVDC and VMPET are high barrier materials, cold sealing glue can be sealed at very low temperature, heat does not affect the chocolate, because the kernel contains more grease, easy to oxidize metamorphic, so the structure increased the oxygen resistance layer.
