A high-opacity cellulose-free synthetic paper is formed from a wet-laid nonwoven web of thermoplastic fibers, all or most of which fibers are made of a predetermined polymeric material. The wet-laid web is dried to remove excess water, drying being carried cut at temperatures below the melting temperature of the predetermined polymeric material. The dried nonwoven web is saturated on at least one side with a pigmented binder forming a continuous coating thereon. The binder is cured at temperatures below the melting temperature of the predetermined polymeric material.

Recyclable polymeric synthetic paper and method for its manufacture

A degradable agricultural mulch, mat or ground cover including cotton linters fibers, hardwood kraft pulp fibers, softwood kraft pulp fibers, and a water holdout material which is strong enough to be laid mechanically and is 100% photo- or biodegradable.

Degradable cotton base cellulosic agricultural mat

A gloss coating composition comprising radiation curable oligomers and monomers, and photosensitizers in a homogeneous mixture having a viscosity in the range of 4500 to 8000 cps; wherein the presence of the photosensitizers causes polymerization of the radiation curable oligomers and monomers when exposed to an ultraviolet light source. The coating composition is applied to at least one surface of a substrate and exposed to an ultraviolet light source resulting in curing of the composition onto the substrate surface without substantial penetration into the substrate surface forming a gloss coated substrate.

An in-mold label material is a nonwoven mat of fibers having one side fused with the outer surface of a polymeric container and the other side coated with a pigment-containing latex suitable for printing thereon. The label paper is manufactured from commercially available fibers combined in water into a homogeneous mixture and then formed into a mat employing a wet-lay process. For use with polyethylene containers, the label may be a web consisting of 88-100% polyethylene fibers and 0-15% polyvinyl alcohol fibers or 70-100% polyethylene fibers, 0-15% polyvinyl alcohol fibers and 0-30% polypropylene fibers. For use with polyester containers, the label may be a web consisting of 50-90% polyester staple fibers, 10-40% bicomponent polyester/co-polyester, core/sheath binder fibers and 0-10% polyvinyl alcohol binder fibers thermally bonded together. The nonwoven web of fibers has a pigmented coating. After the material has been cut into labels, the labels may be applied to the blow-molded containers in-mold without the use of an adhesive material using a conventional in-mold labeling technique or post-mold using adhesive.

Recyclable polymeric label paper

A degradable agricultural ground cover which is composed of high density polyethylene polymer fiber and cellulose pulp which is 100% photo and biodegradable for use in weed control and moisture retention in soil. The unique agricultural mat or cover lasts 8-12 weeks before serious photo and biodegradability occurs, while allowing crop plants sufficient time to mature and produce. The sheet totally disappears with plowing and tilling, becoming a soil extender until complete degradation occurs.

High gloss ultraviolet curable coating

A method and apparatus for producing a paper product having a surface with enhanced gloss. The method includes the following steps: Applying a continuous layer of an impressionable coating material to a paper product; contacting the layer of coating material with a polymer release film having a smooth and glossy surface substantially free of defects, the surface having non-adhering and release characteristics; and solidifying the coating material during contact with the release film. Using this technique, a smooth and glossy surface of the release film is substantially imparted to a surface of the layer of solidified coating material. In the case of clay-coated substrates, the coating is solidified by heating, whereas in the case of polyethylene-coated substrates, the coating is solidified by cooling. The end product is a coated substrate in which the coating has a glossy surface to which the texture of a film has been imparted.
