Abstract: A method for laser scoring a film comprising at least 90% polyolefin comprises scoring a moving web of the film by utilizing the peak pulse power of a laser at a frequency of about 20 kHz or less to create a scored film with a score feature comprising a series of non-overlapping scored spots. In another aspect, a laser scored film comprises at least 90% polyolefin; and a score feature comprising a series of laser-formed non-overlapping scored spots on the film having a cut size of between 0.15 mm and less than 0.5 mm, and a tie length between 0.15 mm and less than 0.5 mm.

Abstract: A spiral part used as a tamper evident feature an a peal reclose label. The spiral is formed on a pressure sensitive adhesive label, and the spiral is unraveled in order to open the package. Once unraveled, it is difficult to reclose the package with the spiral in its original place. In one embodiment, there is a special color to the label, so that once the package is opened, it can be seen.

Abstract: Peel-Reclose packaging material formed using an adhesive label in combination with laser scoring technology. The adhesive label is applied over laser scored material before or after the laser score forms a pattern smaller than the adhesive label. The adhesive label and laser scored packaging material can then be opened and resealed. In one embodiment the adhesive label in combination with the packaging material has tamper resistant features.

Abstract: A microwavable package is formed with venting mechanisms that are arranged in one of a number of different ways, and are covered with a pressure sensitive adhesive label. While the vents are covered with the pressure sensitive adhesive label, the package is hermetically sealed. The label protects the venting mechanisms from breakage due to product mishandling and abuses during storage and transportation. Prior to be cooked the consumer will remove or peel back the pressure sensitive adhesive label exposing or opening the venting mechanisms. Such vents can be of multiple different shapes, including a perforated shape whose center portion is removed or center portions sticks to the pressure sensitive adhesive label when the label is pulled back and removed from the package. The package is then placed in the oven or microwave and the product inside can be cooked safely.

Abstract: 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.
