ABSTRACT:
Sheet materials and packages capable of holding hard-to-hold products such as methyl salicylate. The preferred embodiments include a foil layer 12 and a layer 14 of EVOH between foil layer 12 and the enclosed product. An anhydride modified adhesive layer 18 is disposed between the EVOH layer 14 and the product 52. Additional layers are used in the sheet material for purposes of adhesion, appearance, protection, body, and the like. One embodiment of the invention is a coextruded film comprising the EVOH layer 514, a surface layer 516 of LLDPE, an intervening adhesive layer 518, and a fourth covering layer 519 for covering and protecting the EVOH layer 514, especially from physical abuse. The sheet materials of the invention may be made into packages by means of fin seals 54 or lap seals 50.
