A new printing technique and an energy-saving thermoforming process enable preprinted food trays to be produced easily and cost-effectively. The combination of the two technologies enables the packaging trays to be print-registered for the first time, claims developer Coextruded Plastic Technologies Inc. (CPT), a thermoformer in Edgerton, Wis. CPT has developed a process to make preprinted sheet that can be print-registered on the forming line, thus eliminating expensive merchandising sleeves and labels, reducing weight, and enhancing the product's "green" image, says CPT president Linda Bracha. CPT's GoGreen preprinted trays are made via a patented thermoforming method that reportedly uses 30% less energy. The company declined to disclose details of its custom-made machinery. Trays are formed from foamed PP sheet or a barrier coextrusion of PP with a PE seal layer. Thickness of preprinted trays ranges from 600 microns to 1.2 mm and maximum tray size is 8.5 × 5 in.

    New cost-effective technologies are designed to make aluminum an attractive alternative to tool steels in a range of plastics molding processes. One method uses a plasma technique to convert the aluminum surface into a hard, dense, wear-resistant ceramic. Another approach uses electro-deposition to apply a surface coating with high hardness, corrosion resistance, and chemical resistance.
