We often mention the vacuum bags have what use, used in what place, have what effect, for a piece of material, we rarely know.
Generally have the following material is suitable for printing into a vacuum bags:
PE material: it is suitable for low-temperature vacuum bags.So you need to heating of the product is not suitable for use, use more frozen seafood.
RCPP material: suitable for high temperature cooking bags, so high temperature cooking bags mostly use this material.
PA material: increase physical strength, durability performance good strength.
PET materials: increased mechanical strength.
AL materials: we often mentioned material of aluminum foil, with a high barrier property, shading, moisture resistance.
Increases the PVA material cut off performance, high barrier coating
Generally according to the needs of customers, set fire to these materials.Generally as follows:
PA/PE or PA/RCPP
PET/PE or PET/RCPP
Also have three layers of vacuum packing bag, four layer vacuum bags, in order to increase the material quality performance:
PET/PA/PE
PET/AL/RCPP
PA/AL/RCPP
PET/PA/AL/RCPP
Are all these vacuum bags have role
1. Cut off the air performance is strong, anti-oxidation, waterproof, moistureproof.
2. Strong mechanical properties, high blast resistance, resistance to puncture tear resistance is strong.
3. High temperature (121 ℃), resistant to low temperature (- 50 ℃), oil resistant, good performance.
4. Avirulent insipidity, accord with food, medicine packaging hygiene standards.
5. Heat sealing performance is good, softness, high separation performance is good.
