    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.

    Abstract: The invention is an improved multiple layer packaging sheet material which can be formed into closed and sealed packages suitable for holding products containing substantial fractions of cyanoacrylate. The invention depends on the positioning of high density polyethylene in direct contact with the cyanoacrylate-type product, and positioning a primer on the other side of the high density polyethylene. Preferred embodiments of the sheet structure include additional layers to provide barrier and abuse resistance properties, and the necessary adhesive materials to hold the various layers of the structure together with good adhesion. Additional layers are contemplated. The sheet structure can be formed into a package which positions the high density polyethylene adjacent the cyanoacrylate product, and between it and the other layers at all locations of contact between the cyanoacrylate product and the packaging sheet material.

    Abstract translation: 本发明是一种改进的多层包装片材料，其可以形成为适于保持含有大量氰基丙烯酸酯的产品的封闭和密封包装。 本发明取决于高密度聚乙烯与氰基丙烯酸酯类产品直接接触的定位，并将底漆定位在高密度聚乙烯的另一侧。 片状结构的优选实施例包括提供阻挡和耐滥用性能的附加层，以及用于将结构的各个层保持良好粘合力所需的粘合剂材料。 预期附加层。 片状结构可以形成为将高密度聚乙烯与氰基丙烯酸酯产物相邻并且在氰基丙烯酸酯产物和包装片材料之间的所有接触位置处与其它层之间定位的包装。

    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. A carboxy modifed 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, 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 using fin seals 54 and lap seals 50.
