摘要： This invention comprises a self-supporting, temperature-stable, indicia-bearing laminate of at least one layer of a non-oriented polyolefin film having an indicia array and a layer of a non-oriented polyolefin support film. The indicia layer laminate is formed by printing a carrier sheet with at least one layer of a printing ink comprising a mixture of particulate polyolefin, indicia material and a polyolefin-compatible resin. The polyolefin support film is printed as a layer over the indicia layer with a mixture of a polyolefin and a polyolefin-compatible resin. The printed layers are cured into non-oriented films, forming an indicia transfer. The transfer is used by removing the indicia-bearing laminate from the carrier sheet and applying the laminate to the inside surface of a rotational mold where it melts and fuses into the outer wall of a polyolefin product during the formation of the product in the rotational molding cycle.

摘要： An ink comprises a mixture of finely subdivided polyethylene powder, an aliphatic or aromatic hydrocarbon solvent, a dispersing agent, an ink additive such as a dye or pigment and/or a physical property enhancing additive such as alumina, glass beads, silica, metal flakes, etc. Preferably high and very high molecular weight polyethylene is used, alone or in mixture with lower density polyethylene in amounts from 25 to 45 weight percent in the ink. The polyethylene can have a particle size from 1 nanometer to 150 microns. The printing ink can be used to prepare a transfer having a decorative layer printed onto a carrier sheet. The printed layer is thermally treated to remove hydrocarbon solvent. The transfers are applied to the surfaces of molded polyethylene or polypropylene parts with adequate heat, pressure and time to fuse the transfers into the walls of the parts, as by hot-stamping.

摘要： There is disclosed an enhancement composition and a method for its use in a molding process. The enhancement composition is applied to the interior surfaces of the mold cavity used in a molding process such as blow molding, injection molding, thermoforming or rotational molding. The enhancement composition is applied prior to closing of the mold and molding of the plastic article. The enhancement composition comprises a liquid carrier containing up to about 50 weight percent of enhancement solids which comprise a mixture of an enhancement solid such as particles of varied thermoplastic and thermosetting resins, metal flakes, glass beads, carbon, graphite, etc., and a binder solid which can be hydrocarbon resin, wax, rosin or terpene base resin. The invention provides for almost unlimited modification of the surfaces of molded plastic products, offering the plastics fabricator the ability to mold products having very specialized surface properties with a low cost structural polymer, e.g., a product molded of low cost, low density polyethylene having the surface characteristics of Teflon®.

摘要： There is disclosed a method for the permanent application of indicia to the surface of the polyolefin object by applying pigmented material to the surface in an indica pattern, preferably from a transfer sheet. Preferably the pigmented material is a mixture of finely divided pigment, hydrocarbon wax and finely divided polyolefin. The polyolefin surface bearing the indicia is coated with a coating mixture comprising a mixture of polyolefin and a binder such as a rosin or wax. Thereafter, the coated, indicia-bearing polyolefin surface is surface-heated to a temperature sufficient to fuse the coating and incorporate the coating and indicia permanently into the polyolefin object. The heating can be performed by passing a heat source across the surface.

摘要： This invention is a method for the precise placement of indicia with high resolution into the wall of a hollow-form, molded plastisol part. The method includes the steps of preparing a plastisol graphic transfer by casting a base layer of plastisol onto a carrier sheet, printing indicia with pigmented plastisols onto the base layer of plastisol to form a graphic transfer, and over printing the graphic transfer with a body layer of plastisol. After each layer of plastisol is deposited, the layer cured by heating before depositing the next layer and the transfer is heated to cure the final, body layer. The transfer is applied to a selected inside surface of a conventional rotational mold by applying a high-solvent-content adhesive to the mold surface, stripping the plastisol transfer from the carrier sheet and applying it against the adhesive coated mold surface, and pressing the transfer against the adhesive-coated surface of the mold, permitting the applied transfer to dry over a short interval and then continuing with an otherwise conventional rotomolding or slush molding process to obtain a molded hollow form part having the indicia permanently fused into the wall of the part.

摘要： A low-temperature, liquid-phase injection molding method includes external heating of the mold and a feed composition that is a mixture of a carrier, binder, and a powdered polyethylene. The carrier and binder component can be a very low density polyethylene, petroleum jelly, hydrocarbon waxes, liquid hydrocarbon oils, or mixtures thereof. The powdered polyethylene component is finely subdivided polyethylene, preferably ultra high molecular weight, having a low melt index, at least no greater than 30. The carrier and binder component is used in sufficient quantity to provide a thixotropic mixture with a consistency of toothpaste, typically having a stirred viscosity up to 30,000 centipoise at the injection temperature of the molding process. The process further includes controlling external mold heating to provide minimal heating of the core of a formed part, thereby permitting one to incorporate components within the part without damage to temperature sensitive elements in the components.

摘要： The ink of the invention comprises a mixture of finely subdivided polyethylene powder, an aliphatic or aromatic hydrocarbon solvent, a dispersing agent, an indicia material additive such as a dye or pigment and/or a physical property enhancing additive such as alumina, glass beads, silica, metal flakes, etc. Preferably high and very high molecular weight polyethylene is used, alone or in mixture with lower density polyethylene in amounts from 25 to 45 weight percent in the ink. The polyethylene can have a particle size from 1 nanometer to 150 microns, preferably from 0.1 to 100 microns. The printing ink can be used to prepare a transfer having a decorative layer printed onto a carrier sheet. Various printing methods can be used to prepare the transfer such as gravure printing with etched or engraved chrome-plated or copper rolls; flexography printing with a flexible printing plate; and screen printing. The preferred method is screen printing. The printed layer is thermally treated to remove hydrocarbon solvent. The transfers are applied to the surfaces of molded polyethylene or polypropylene parts with adequate heat, pressure and time to fuse the transfers into the walls of the parts. For this application, the transfer is applied by a commercial hot-stamping, reciprocal press which heats the transfer to temperatures from 450° F. to 650° F., and compresses the transfers at a controlled pressure from 500 to 1000 psig. against a molded part, melting and fusing the transfers into the wall of the molded part.
