SYSTEMS AND METHODS FOR INTERLEAVING MATERIAL IN PRINTED ROLLED SUBSTRATE MATERIALS TO PREVENT OFFSET
20170341291 · 2017-11-30 ·

A system and method are provided for implementing a process by which printed rolls of substrate material web have additional material layers interleaved between the rolled material web layers to substantially eliminate back transfer or roll offset of printed images on the back sides of the rolled material substrates. In a process for pre-printing thermoforming grade plastic materials to produce rolls of substrate material for use in a thermoforming process, ink compositions, particularly adapted for the thermoforming process, are deposited on substantially continuous webs of substrate material. The webs of substrate material are then re-rolled with separate layers of low surface energy substrate material interleaved between the layers of the printed substrate material in order to substantially eliminate imaging defects produced by back transfer of printed images on to the backs of layers of the printed substrate material stored in rolls.

Heat-resistant food container and its manufacturing method

This invention provides a food container which can be manufactured cheaply by using inexpensive general PET resin or further inexpensive PET resin for fiber or recovered PET flakes, and nevertheless, which has a high heat resistance up to 250° C., and the container is obtained by adding a chain extender and a compatibilizer and talc to PET resin, charging the mixture into an extruder 30 having two or more vent holes, degassing under a condition where the PET resin is melted with heating by sucking at a high vacuum of −99.99 kPa or lower from the vent holes 33, 34, thereafter, forming a sheet by extrusion molding, pressure-forming with vacuum the sheet by a thermoforming machine, forming the container by keeping in a mold at 100-220° C. The container has a total of the content of crystal portion represented by the following formula and the content of talc being 25% by weight or more.

20170334601 · 2017-11-23 ·

A plastic internally hollow body has a cavity for containing liquids, solids or gases, and includes a main body shaped and having an inner surface at least partially defining the cavity. The inner surface terminates in a shaped edge that delimits a coupling aperture to the cavity. The internally hollow body includes a closure body, having an outer sealing surface suitable at least partially engaging the inner surface of the main body. The closure body at least partially closes the cavity in correspondence of the coupling aperture. The main body is joined to the closure body at least partially along the shaped edge by a joining element over-moulded to the main body and the closure body and covering the over-moulding seat resulting between the main body and the closure body. A method for making the internally hollow body over-moulds the joining element by injection moulding with an over-moulding mould.
