An apparatus for curing concrete includes a multiple layer polyolefin film and an absorbent layer. The polyolefin film layer can include pH modifying components and antiskid components. The absorbent layer can also include pH modifying components. The absorbent layer can include nonwoven fabric. The apparatus can be applied to curing concrete after hydration water is applied to the curing concrete. The apparatus can also be used to enclose poured concrete members during transport of the members so as to continue the curing process during transport. The film can also be used as a barrier layer between the ground and poured concrete.

A multilayer structure may include a polyethylene-based polymeric film comprising: a sealing layer; at least one middle layer; and a printing layer; and an external layer of ultraviolet or electron beam curable ink or varnish cured on the printing layer of the polyethylene-based polymeric substrate, wherein the multilayer structure has a thermal surface resistance such that when sealing bars are applied to the polyethylene-based polymeric film in cycles of sealing of no more than 2 seconds and at a temperature corresponding to the melting temperature of the polyethylene-based polymeric film, the sealing bars remain free of polymer.

The invention comprises a method of making synthetic turf. The method comprises applying an ethylene-vinyl acetate copolymer adhesive to a first primary surface of a tufted primary backing to form a coating thereon and wherein the primary backing is tufted with a plurality of synthetic filaments to form a face pile extending outwardly from a second primary surface of the synthetic turf opposite the first primary surface and heating the ethylene-vinyl acetate copolymer adhesive to a temperature above its melting point so that the ethylene-vinyl acetate copolymer adhesive melts and at least partially flows into the primary backing. The method also comprises heating a linear low-density polyethylene film to a temperature below the softening point of the film and pressing the heated linear low-density polyethylene film into contact with the polymer coated first primary surface of the tufted primary backing. The method further comprises allowing the ethylene-vinyl acetate copolymer adhesive and the linear low-density polyethylene film to cool, whereby the linear low-density polyethylene film is adhered to the tufted primary backing.

A heat-shrinkable film which includes an ethylene-based polymer multilayer or monolayer film and a coating on an outer surface of the ethylene-based polymer film.
