Abstract

See full text

An adjustable system for controlling an amount of gas permeability allowed through multilayer material. A laser is controlled through a controller, and the laser processes the multiple layer material to remove only some of the layers in only an area. The area can be a pattern such as a line, or can just be a pattern of areas. The layers are removed without fully penetrating the material, thus adjusting the gas permeability. This allows gases and vapors to transmit into the package thru the scored area more specifically thru the remaining material at a faster rate than a non-scored material. The pattern can score along a line to allow gases and vapors to pass through more rapidly. The laser beam does not cut through the entire structure, and the package remains sealed. This means, therefore, that the amount of gas/vapor permeability can be changed for a sealed package, e.g., with material therein.
