<p>A thermoformable, multi-layer plastic sheet with gas barrier properties is disclosed having an inner gas barrier layer, a glue layer applied to either side of the gas barrier layer and layers of a polyolefin composition bonded to the glue layers. To increase the tensile strength of the sheet during heating for the purpose of thermoforming, a second polyolefin layer is bonded to at least one of the two polyolefin layers, the second polyolefin layer having a lower melt index than the layer of the polyolefin composition beneath it.</p> |
