Abstract
A packaging laminate for a package possessing superior gas and light barrier properties is disclosed, and a method of producing the packaging laminate. The packaging laminate includes a layer of a silicon oxide compound serving as gas barrier and a layer of metal serving as light barrier, these layers being deposited by vacuum deposition on each respective layer of plastic serving as carrier, and being permanently bonded to one another through an interjacent layer of adhesive for the formation of the packaging laminate. By regulating the thickness of the gas and light barrier layers independently of one another, an optional combination of gas and light barrier properties is made possible, whereby the packaging laminate may be more or less 'tailor made' for each type of product which is to be packed.
