ABSTRACT:
The present invention provides a method of producing a gas-permeable parcelling film for use in a container for isolating a product to be preserved from a freshness keeping agent placed within the container. The parcelling film has a gas-permeable formed member which is obtained by subjecting plastic fibers to a paper-making process and a drying process to obtain a dried sheet of plastic fibers, and then subjecting the dried sheet to a forming process into the formed member. The parcelling film is impregnated with fluororesin, before being subjected to the forming process.
