Design Requirements For Retort Pouches, Biscuit Food Packaging Bags, And Stand-up Pouches

- Aug 12, 2019-

For the company's products, the bag is a piece of clothing, so how to design, what materials can be used to make the bag look better, the quality is better? Here's a look at the design of three common types of bags:

First, cooking bags


1, packaging requirements


For the packaging of meat, poultry, etc., it is required to have good barrier properties and resistance to bone piercing. Under the cooking conditions, the sterilization is not broken, cracked, shrinked, and has no odor.


2, the 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 reasons


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


PA: High temperature resistance, high strength, flexibility, good barrier properties and resistance to breakage.


AL: Best barrier and high temperature resistance.


CPP: It is a high temperature cooking grade, good heat sealability, non-toxic and tasteless.


PVDC: barrier material.


GL-PET: Ceramic vapor-deposited film with good barrier properties and microwave penetration.


For the specific product to choose the appropriate structure, the transparent belt is mostly used for cooking, AL foil bag can be used for ultra-high temperature cooking.


 


Second, biscuit packaging


1, packaging requirements


Good barrier properties, strong opacity, oil resistance, high strength, odorless and tasteless, and packaged.


2, the design structure


BOPP/EXPE/VMPET/EXPE/S-CPP.


3. Design reasons


BOPP: good rigidity, good printability and low cost.


VMPET: good barrier properties, protection from light and oxygen, water blocking.


S-CPP (modified CPP): good heat sealing at low temperature and oil resistance.

Third, liquid detergent stand-up pouch


1, packaging requirements


High strength, impact resistance, burst resistance, good barrier property, good rigidity, standing up, stress cracking and good sealing.


2, the design structure


Stereo: BOPA/LLDPE; bottom: BOPA/LLDPE.


Stereo: BOPA / strengthen BOPP / LLDPE; bottom: BOPA / LLDPE.


Stereo: PET/BOPA/reinforced BOPP/LLDPE; bottom: BOPA/LLDPE.


3. Design reasons


The above structure has good barrier property and large material rigidity, and is suitable for a three-dimensional packaging bag, and the bottom is flexible and suitable for processing. The inner layer is modified PE and has good anti-sealing pollution. Strengthening BOPP increases the mechanical strength of the material and enhances the barrier properties of the material. PET improves the water resistance and mechanical strength of the material.
