The material selection of biscuit packaging bag

2022-10-07 09:50

1. Packaging requirements: good barrier, strong light blocking, oil resistance, high emphasis, no odor, packaging upright


2. Design structure: BOPP/EXPE/VMPET/EXPE/S-CPP


3. Reasons for material selection.


3.1 BOPP: good rigidity, good printability, low cost


3.2 VMPET: good barrier, light and oxygen barrier, water barrier


3.3 S-CPP (modified CPP): good low-temperature heat sealability, oil resistance


Material selection of steaming packaging bags


1. Packaging requirements: used for meat, poultry and other packaging, requires packaging barrier, good resistance to bone puncture, sterilization in the physical test of high temperature cooking conditions do not break, not crack, not shrink and no odor.

2. The design structure is mainly divided into two categories.

2.1 Transparent class: BOPA/CPP, PET/CPP, PET/BOPA/CPP, BOPA/PVDC/CPP, PET/PVDC/CPP, GL-PET/BOPA/CPP

2.2 Aluminum foil category: PET/AL/CPP, PA/AL/CPP, PET/PA/AL/CPP, PET/AL/PA/CPP

3. Reasons for choosing materials.

3.1 PET: high temperature resistance, good rigidity, good printability and strength

3.2 PA: high temperature resistance, high strength, flexibility, good barrier and puncture resistance

3.3 AL: best barrier and high temperature resistance

3.4 CPP: high temperature cooking grade, good heat sealability, non-toxic and odorless

3.5 PVDC: barrier material

3.6 GL-PET: ceramic evaporation coating, good barrier, microwave permeability

For specific products to choose the right structure, transparent tape is mostly used for boiling, AL aluminum foil can be used for high temperature steaming
