Abstract
A flexible laminated packaging material (100) comprises a plurality of layers, at least two of which are bonded together by a layer of adhesive (108). A first layer (113) comprises a continuous metallic foil (110) and a second layer (111) comprises a continuous web of material incorporating or coated with a laser retardant additive (106). The material may be scored or cut with a laser (114, 118) so as to produce offset scores or cuts (122, 124) wherein a first cut (124) is made through the first layer (113), but not past the second layer (111) and a second cut (122) is made through the second layer (111), but not past the first layer (113). The laser retardant additive (106) attenuates the power of the laser to help control the depth of the cuts. A method of producing the material by laminating the first and second layers using an adhesive is also disclosed. The method may comprise applying a laser beam to the first web so as to score or cut the first web, but not the second web; and applying a laser beam to the second web so as to score of cut the second web, but not the first web.
