External Vacuum Sealer An external vacuum packing machine is a type of packaging equipment designed to remove air from a package and create a vacuum seal around the contents. Unlike chamber vacuum sealers, external vacuum sealers are suitable for packaging products of various sizes and shapes without the need for a dedicated chamber. The process typically involves placing the open end of a vacuum bag outside the machine, which then removes the air and seals the bag. These machines are commonly used in households, small businesses, and commercial kitchens for preserving food items, extending shelf life, and preventing freezer burn. External vacuum packing machines are user-friendly, versatile, and well-suited for applications where airtight packaging is essential.
