A method of producing ink-jet printed images with high resistance to physical and chemical damage on plastic surfaces, by coating the plastic object with an inkjet receptive layer comprising a mixture of hydrophilic polymers and UV curable pre-polymers deposited from an emulsion, ink-jetting an image onto the coating using ink-jet ink comprising a colorant and aqueous carrier, warming the printed surface to drive part of the water in the ink into the surface coating and to evaporate the other part of the water, UV curing the dried surface and over-coating the UV cured surface with lacquer or with lamination material.

A method of fabricating plastic objects having an insert of Lenticular lens material integrally bonded or otherwise attached therein. In one embodiment, the method is used to fabricate a container, such as a conical cup, by first manufacturing or providing a sheet of Lenticular material comprising layers of lens material and optical ridges and grooves and an ink layer printed on the flat side of the lens material. To protect the ink from the heat of molten or moldable plastic during later plastic processing, a thermally protective substrate is attached or bonded to the ink layer by using adhesives to attach a plastic substrate or by coating the ink with coating materials that thermally protect the ink from high temperatures. In one embodiment, the protective substrate is applied in a two step process of first placing a plastic hot melt onto a polyester or other material release liner and, after cooling of the hot melt, using heat and pressure to laminate or bond the hot melt plastic to the ink and then removing the liner. Lenticular inserts are cut out of the Lenticular material sheets and the inserts are positioned within a mold where the container is formed by injection, blow, or other molding process. In this step, the substrate acts as a bonding surface as it contacts the molten plastic, melts, and then cools forming a bonding interface with the plastic used to form the container.

A photochromic plastic object which is composed of a transparent polymeric synthetic resin material, into or onto which at least one substantially mesoporous inorganic host structure is introduced or applied containing one or more embedded organic photochromic dye molecules so as to form a photochromic nanocomposite material. In contrast to prior techniques of adding or applying the photochromic organic dyes to the monomer mixture or prepolymer of a transparent synthetic resin material in a molecular form, in the photochromic plastic article of the present invention color is generated by using the photochromic nanocomposite particles or photochromic nanocomposite structures.

Articles produced from hydrophobic polymers (e.g., polyethylene) are surface-coated with thin films of starch in order to render the surfaces hydrophilic. The thin coatings form on the surfaces of plastic objects when the objects are placed in contact with hot, aqueous solutions of starch. These starch coatings are adherent to the hydrophobic plastic surfaces under both wet and dry conditions, and they permit the surfaces to be uniformly wet with water. The coatings may be rendered even more adherent when wet by graft polymerizing the starch with a synthetic monomer. Resultant products have the potential for improved biocompatibility, improved compatibility with hydrophilic reagents, reduced build-up of electrostatic charge, reduced blocking, reduced friction, improved absorption of water-based dyes, and improved adhesion properties. The starch coatings are non-toxic, inexpensive and biodegradable.

An injection molding machine that uses a mold and a native controller to operate according to an original mold cycle to mold plastic objects is retrofitted with a retrofit controller; the retrofitted machine uses the mold and the retrofit controller to operate according to a retrofit mold cycle to mold plastic objects. The retrofit mold cycle has a maximum injection pressure that is less than a maximum injection pressure of the original mold cycle. The retrofit mold cycle can also have more constant injection pressures than the original mold cycle.
