<p>A packaging laminate for a package possessing superior gas and light barrier properties is disclosed, and a method of producing the packaging laminate (10). The packaging laminate includes a layer (17) of a silicon oxi de compound serving as gas barrier and a layer (13) of metal serving as light barrier, these layers (17 and 13) being deposited by vacuum deposition on each respective layer (12 and 16) of plastic serving as carrier, and being permanently bonded to one another through an interjacent layer (20) of adhesive for the formation of the packaging laminate (10). By regulating the thickness of the gas and light barrier layers (17 and 13 respectively) independently of one another, an optional combination of gas and light barrier properties is made possible, whereby the packaging laminate (10) may be more or less "tailor made" for each type of product which is to be packed.</p> |
