BREATHABLE FILM FOR PACKAGING GARDEN STUFF, AND BREATHABLE BAG FOR PACKAGING GARDEN STUFF

摘要

PROBLEM TO BE SOLVED: To provide a breathable film for packaging garden stuff, which has the primary objective of maintaining the freshness of the garden stuff and which is suitable for packaging the garden stuff in a hermetically sealed state, and a breathable bag for packaging the garden stuff, which uses the breathable film.SOLUTION: A crazed film with air permeability is obtained by forming fine continuous holes (voids), which penetrate front and back sides and have gas permeability adjusted, on the whole surface or a part of a polymer resin film. The garden stuff is packaged in a hermetically sealed state with the film. Thus, the freshness of the garden stuff is maintained by controlling a degassed state brought about by self-respiration of the garden stuff.SELECTED DRAWING: Figure 1
