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.
