Retort Pouch And Retortable Pouch

Microwave frozen instant food cooking bags, bn pack has launched a variety of categories such as fried rice, bibimbap, pasta, etc. The product packaging adopts the black technology of "cooking in the bag", and the inner, middle and outer layers are made of three different materials: LLDPE, PET , OPP, to achieve food-grade preservation, odor blocking and strong sealing. In addition, the product also adopts thermal convection circulating heating bag technology, which can release steam through its own exhaust port during heating, so that the bag does not need to be opened in advance.

Compared with the way of steaming food with heating packs in self-heating pots, microwave heating has scene limitations, but the heating process is safer, the product volume is smaller, and it also has advantages in reducing material costs and transportation costs.

Packaging requirements: For meat, poultry and other packaging, the packaging is required to have good barrier properties, resistance to bone hole breakage, and be sterilized under cooking conditions without breaking, cracking, shrinking, or peculiar smell.

Design structure:

Transparent: 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

Design reason:

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

PA: high temperature resistance, high strength, flexibility, good barrier properties, puncture resistance.

AL: Best barrier properties, high temperature resistance.

CPP: high temperature cooking grade, good heat sealing, non-toxic and tasteless.

PVDC: High temperature resistant barrier material.

GL-PET: ceramic vapor deposition film, good barrier property, transmits microwave.

Choose the appropriate structure for specific products, most of the transparent bags are used for cooking, and AL foil bags can be used for ultra-high temperature cooking.
