Patent

CA 2544243

The invention is a trap- printable laminate having an OTR that is sufficiently high to help facilitate the passage of oxygen through the laminate without sacrificing the properties of the laminate that are necessary for lamination, printing, and heat sealing to a support member, such as a tray. In one embodiment, the laminate has an OTR of at least 4,000, cc at STP/m2/24 hr/atm. The laminate may be particularly useful in high oxygen packaging applications where it may be desirable to have a product bloom from exposure to oxygen. The high OTR of the laminate may allow oxygen to pass through the laminate and interact with portions of a product that may be in direct contact with the laminate.
