A foam-based expansion joint seal system packaging which facilitates transport and reduces the need for internal splices which includes laterally-flexible packaging bodies. The packaging bodies may include flutes, corrugations or prisms on their exterior to enable lateral bending of the foam-based expansion joint seal system packaging, even into coils.

Disclosed are an entrained polymer or an entrained polymer composition, and a method for forming and adhering an entrained polymer structure to a substrate using the entrained polymer or an entrained polymer composition. The method includes providing a substrate configured to receive application of a molten entrained polymer. A particulate entrained polymer in molten form is applied in a predetermined shape, to a surface of the substrate, to form a solidified entrained polymer structure on the substrate. The entrained polymer includes a monolithic material formed of at least a base polymer and a particulate active agent. The surface of the substrate is compatible with the molten entrained polymer so as to thermally bond with it. In this way, the entrained polymer bonds to the substrate and solidifies upon sufficient cooling of the entrained polymer.

A process for preparing a flexible packaging material (5) is described. The process comprising providing a first flexible substrate (3) having a first surface on which an ink composition (4) is printed, the printed ink composition comprising an ink resin comprising polyvinyl chloride, polyvinyl butyral, nitrocellulose, polyurethane, polyamide or a UV curable resin; providing a second flexible substrate (1); depositing a layer of thermally activatable laminating material (2) onto one of a first surface of the second flexible substrate and the first surface of the first flexible substrate on which the ink composition is printed, the thermally activatable laminating material comprising a thermally activatable polymer selected from a copolymer of an alkylene monomer and an acrylic acid or methacrylic acid monomer, a copolymer of an alkylene monomer and an alkyl acrylate or alkyl methacrylate monomer, a polyurethane, an ionomer, a copolymer of alkylene monomers, a maleic anhydride modified polyalkylene and an acid modified polyolefin; and contacting under conditions of heat and/or pressure the layer of thermally activatable laminating material with the other of the second flexible substrate and the first surface of the first flexible substrate on which the ink composition is printed.

A method for three-dimensionally forming a resin packaging member. The resin packaging member is heated to a temperature not higher than the Vicat softening temperature of the packaging member, and then compression shaping is conducted at a temperature not lower than room temperature and not higher than the Vicat softening temperature so as to form a three-dimensionally shaped portion with a large protrusion.
