COATED CELLULOSIC FILM HAVING SURFACE RUGOSITIES AND INTENDED AS PACKING MATERIAL FOR SOFT CHEESE; PROCESS FOR ITS MANUFACTURE

摘要

A cellulose packaging film for packaging soft cheeses has a controlled permeability to oxygen, carbon dioxide, ammonia and water vapor which allows the cheese to properly ripen while wrapped in the packaging material. The cellulose packaging film is formed from a cellulose film substrate with a coating layer of a nitrocellulose varnish having distributed therein casein or starch particles which have a diameter which is greater than the thickness of the coating layer. In use, the soft cheese is wrapped with the cellulose packaging film with the nitrocellulose varnish layer facing the soft cheese.
