Product Description
Our PA/PP Retort Vacuum Pouches are the industry benchmark for shelf-stable corn packaging. Specifically formulated for the "Pre-cooked Corn on the Cob" and "Vacuum-Packed Sweet Corn" segments, these bags utilize a sophisticated lamination of Biaxially Oriented Polyamide (BOPA) and Retort-grade Cast Polypropylene (RCPP).

Professional Grade Retortable Packaging for Whole Corn ,Specifically engineered for the corn processing industry, our PA/PP co-extruded/laminated vacuum bags provide an ideal solution for products requiring post-packaging sterilization. The combination of Polyamide (PA) for strength and Retort-grade Polypropylene (RCPP) for heat sealing ensures that the package maintains its integrity under extreme conditions.This pouch is optimized for 121degrees retort sterilization for up to 30 minutes, effectively eliminating bacteria while preserving the natural sweetness, moisture, and golden color of the corn.

Comment & FAQ
1.What is the difference between chamber vacuum bags and vacuum seal bags (used in edge, suction and external vacuum sealing machines)?
Chamber vacuum bags and vacuum seal bags for exterior sealing are made from coextruded polyethylene and nylon. There are three simple differences between the products!
The first difference is texture. Chamber vacuum bags have a smooth texture, while vacuum bags are embossed to create a bumpy texture.
The second one is the standard thickness. 3 mil vacuum chamber bags tend to be the standard for chamber vacuum sealers. Foodsaver, Weston and others tend to use bags that are about 4 mils thick. Vacuum seal bags and rolls need to be thicker so they can be embossed more easily without puncturing or failing in the created state. There are not only 3 million chamber vacuum bags available, but there are 4-8 million available!
Third one is cost. Vacuum chamber vacuum bags are much less expensive than comparable vacuum bags as the two differences above speak for themselves. Standard thickness and embossing increase the price of external vacuum seal bags and roll.
