Disclosed, among other things, are ways to manufacture reduced density thermoplastics using rapid solid-state foaming and machines useful for the saturation of plastic. In one embodiment, a foaming process may involve saturating a semi-crystalline polymer such as Polylactic Acid (PLA) with high levels of gas, and then heating, which may produce a reduced density plastic having high levels of crystallinity. In another embodiment, a foaming process may produce layered structures in reduced density plastics with or without integral skins. In another embodiment, a foaming process may produce deep draw structures in reduced density plastics with or without integral skins. In yet another embodiment, a foaming process may utilize additives, blends, or fillers, for example. In yet another embodiment, a foaming process may involve saturating a semi-crystalline polymer such as Polylactic Acid (PLA) with high levels of gas, and then heating, which may produce a reduced density plastic having high levels of crystallinity.

A station for heating thermoplastic sheet-like blanks for a thermoforming line includes a heating carousel which can rotate continuously about a central axis and which has a number of heating heads radially spaced apart from the central axis. Each heating head is adapted to receive at least one respective thermoplastic sheet-like blank at a first peripheral region which is outside the carousel, to retain the at least one blank during the rotation of the carousel while supplying heat to it, and to release the at least one blank to a second peripheral region which is outside the carousel and is angularly spaced apart from the first region.

A method of making a double-wall cup having an inner cup defining an inner wall and an outer wrapper defining an outer wall, the method comprising applying an adhesive on the inner wall, holding a portion of the wrapper, at a location between opposing ends of the wrapper, in contact with the adhesive while in spaced relationship with the inner wall to define a spaced condition, and wrapping the wrapper about the inner wall.

A shaped article, a method for making it, and its use. The shaped article is formed from flat fiber material and has a bottom (2), a body (4), and an opening, which is surrounded by a circumferential flange (6). The shaped article (1) comprises a flange stabilizer (10) attached to the second flat side (18) of the flange (6) facing the bottom (2). The flange stabilizer (10) is disc-shaped and has an inner contour (12) corresponding to the desired cross-sectional shape of the shaped article (1) in the region of the opening and can be slipped over the body (4) in the region of the bottom (2) and up to the flange (6). The flat sides (16, 18) of the flange stabilizer (10) extend essentially parallel to the flange (6), defining and stabilizing the cross-sectional shape of the body (4) in the region of the opening and the flange.

Disclosed herein is a process for producing marbled moldings, where a first molding compound and at least one further molding compound are injected from an injection unit of a screw injection molding machine into an injection mold, where the injection unit includes a barrel, a screw having a screw tip and a nozzle where the screw is rotatable and is disposed in the barrel so as to be movable between a forward position and a backward position, with a smaller distance between the screw tip and the nozzle in the forward position than in the backward position, and where the first molding compound includes a first polymer compound and a first colorant, and the at least one further molding compound includes a further polymer compound and optionally at least one further colorant.

Further disclosed herein is an apparatus for production of marbled moldings, and a process for producing the apparatus.

Molded pulp containers with fused junctions and methods of making of same are provided. The present invention provides a pulp container, comprising a molded pulp body, wherein the body comprising a bottom and at least one side wall forming a cavity, wherein the at least one side wall comprising a upper rim, a neck, wherein the neck comprising a upper closure part and a lower rim, a fused junction, wherein a part of the upper rim of the at least one sidewall of the body and a part of the lower rim of the neck are aligned and fused together. The fused junction may be formed by ultrasonic welding.

A mold structure used in an injection molding process to form a cup having broken threads where an A and B mold form a horizontal irregular parting line to alleviate stripping or unscrewing along the threads. The B mold includes a series of segmented surfaces arranged in a helical pattern at an angle from a transverse plane and extending around a longitudinal axis to form a topside surface of the B mold.
