For the company's products, the packaging bag is a kind of clothes, so how to design and what materials can make the packaging bag more beautiful and better quality? Here are three common types of packaging bag design:
1、 Cooking bag
1. Packaging requirements
It is used in meat, poultry and other packaging, which requires good barrier property, bone puncture resistance, sterilization, no cracking, no shrinkage and no peculiar smell under cooking conditions.
2. Design structure
Transparent class:
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。
3. Design reason
Pet: high temperature resistance, good rigidity, good printability and high strength.
PA: high temperature resistance, high strength, flexibility, good barrier, wear resistance.
Al: best barrier, high temperature resistance.
CPP: high temperature resistant cooking grade, good heat sealing, non-toxic and tasteless.
PVDC: barrier material.
Gl-pet: ceramic evaporation coating, good barrier, microwave transmission.
For specific products, the transparent belt is mostly used for cooking, and Al foil bag can be used for ultra-high temperature cooking.
2、 Biscuit packaging
1. Packaging requirements
Good barrier, strong shading, oil resistance, high strength, odorless and tasteless, neat packaging.
2. Design structure
BOPP/EXPE/VMPET/EXPE/S-CPP。
3. Design reason
BOPP: good rigidity, good printability and low cost.
VMPET: good barrier, light and oxygen resistance, water resistance.
S-cpp (modified CPP): good heat sealing property at low temperature and oil resistance.
3、 Self supporting bag for liquid detergent
1. Packaging requirements
High strength, impact resistance, burst resistance, good barrier, good rigidity, standing, stress cracking resistance, good sealing performance.
2. Design structure
Three dimensional: BOPA / LLDPE; bottom: BOPA / LLDPE.
Three dimensional: BOPA / reinforced BOPP / LLDPE; bottom: BOPA / LLDPE.
Stereoscopic: PET / BOPA / reinforced BOPP / LLDPE; bottom: BOPA / LLDPE.
3. Design reason
The structure has good barrier property, large material rigidity, and is suitable for three-dimensional packaging bag, and the bottom is flexible and suitable for processing. The inner layer is modified PE with good sealing resistance. Strengthening BOPP increases the mechanical strength and barrier property of the material. Pet improves the water resistance and mechanical strength of the material.
