Abstract
A laminate which includes a barrier layer of OAUGDP bonded silicon oxide and a cellulosic or thermoplastic base layer. A process for applying same. A package container which includes the laminate.
Claims9
A laminate which comprises a silicon oxide barrier layer formed from a one atmosphere uniform glow discharge plasma (OAUGDP), having an average thickness greater than about 100 nanometers (nm), and a cellulosic or thermoplastic base layer, in which the barrier layer inhibits gas permeability, resists impact, and resists abrasion, wherein the laminate is folded and heat-sealed to form a container, such that the barrier layer is on the interior of the container.
A packaging container which comprises a laminate which comprises a silicon oxide barrier layer formed from a one atmosphere uniform glow discharge plasma (OAUGDP), the barrier layer having an average thickness of greater than about 100 nm, and a cellulosic or thermoplastic base layer and at least one additional layer of thermoplastic, wherein the base layer is between the barrier layer and the at least one additional layer of thermoplastic and the barrier layer provides a barrier against oxygen gas penetrating into the package, and provides resistance to impact and abrasion, wherein the laminate is folded and heat-sealed to form the packaging container, such that the barrier layer is on the interior of the container.
