A radially expansible press plunger including a base plate and a first plunger skirt. A circumferential edge portion of the first plunger skirt is arranged at a guiding surface of the base plate and being arranged radially inward of the circumferential edge of the bottom surface. The first plunger skirt is resiliently transformable between an unexpanded state and a radially expanded state. The expansible press plunger further comprises a second plunger skirt having a plunger skirt side wall with a circumferential edge portion at a bottom end of the second plunger skirt and being arranged radially outward of the circumferential edge portion of the first plunger skirt. The second plunger skirt is resiliently transformable between an unexpanded state and a radially expanded state under influence from the circumferential edge portion of the first plunger skirt.

A synthetic barrier material includes a light-cured polymer and graphene nanoplatelets in parallel alignment in the polymer. Disclosed further is a method for manufacturing the synthetic barrier material. The graphene nanoplatelets are dispersed in a photocurable resin and polarically aligned by an electric field. Furthermore, disclosed is a synthetic barrier film manufactured from the aforementioned synthetic barrier material or the aforementioned method.

The method for producing a container consisting of a rigid outer container and a deformable inner bag. A first screw conveyor supplies a first thermoplastic plastics material for the outer container and at least a second and a third screw conveyor supplies at least a second and a third thermoplastic plastics material for the inner bag to an extruder which coextrudes a parison consisting of at least the first, second and third layers. The parison is inflated by a pressure medium to bring it into contact with the wall of the blow mould, where excess material below the welded seam is cut off and the container is removed from the blow mould. The second thermoplastic plastics material forming the outer layer of the inner bag consists of a material which, in the hardened state, has a rough surface having microscopically small elevations and depressions.

The invention concerns a film based on a binary polymer composition having at least a first polymer and a second polymer. The film is oriented by extruding and stretching the film in at least the machine direction. The glass-transition temperature (Tg) of the first polymer is greater than the orientation temperature and the glass-transition temperature (Tg) of the second polymer is lower than the orientation temperature. Furthermore, a method and use related thereto are described.

Disclosed herein is a method for allowing forming & sealing films to be embossed/debossed with various shapes such as geometric, organic, or fractal and/or combination and various dimensions and depths. The texture or pattern is transferred to the film from an insert. The pattern on the forming & sealing film is then transferred onto the surface of the various proteins including but not limited to chicken, turkey, beef, pork, and plant proteins during the form-fill-seal and cook process. The forming and/or sealing inserts can form various thermoforming films with functional and/or decorative embossing and/or debossing without the use of knitted, elastic, extruded, tightly weaved, plastic netting, and/or compression forming molds and/or release agents for netting removal. Since the forming inserts are constructed using additive manufacturing processes, almost any design can be embossed/debossed onto the forming & sealing film.

Disclosed are a pouch film shaping apparatus including a preheating lamp configured to preheat a metal barrier layer of a pouch film in order to increase stretching force of the pouch film and a pouch film shaping method.

A thermoplastic pre-container, typically a blow molded piece, is provided to form several hollow bodies. The pre-container is elongated along a central axis and includes a bottom section, an opened section and in-between at least one hollow body section. A plurality of circumferential grooves are provided in a pre-container sidewall, each with a bottom line formed in a virtual plane perpendicular to the axis. The bodies are obtained after cutting the pre-container in a direction transverse to the central axis and severing the end sections. Due to the cutting at several of the circumferential grooves, a top opening and a base opening are respectively obtained for at least two hollow bodies, each opening being delimited by an annular inner rim of a body flange.

An injection mold for producing a double walled drinking vessel includes first and second mold portions. The first mold portion forms a first and second cavities corresponding to the outer shape of the outer container and the outer shape of the inner container, respectively. The first and second cavities are located concentrically with respect to a central axis. An index plate is rotatable and axially movable along the central axis relative to the first mold portion. The index plate includes a first core and a second core. The first cavity has a first cavity injection gate for injecting mold material into the first cavity for forming the outer container. The second cavity has a second cavity injection gate for injecting mold material into the second cavity for forming the inner container. The first cavity has a further injection gate for injecting joint material for joining the outer and inner containers.

A chaff resistant and economically recyclable dunnage tray is disclosed. In one aspect, the dunnage tray includes a base portion formed from a first material and a top portion formed from a second material. The top portion is secured to the base portion, and defines at least one cavity or recess for supporting a machine component. The first and second materials are high density polyethylene (HDPE) materials with the second material including polyethylene elastomers, or plastomers. In one example, the dunnage tray is formed by thermoforming a co-extruded sheet including a first layer corresponding to the bottom structural portion and a second layer corresponding to the elastomer or plastomer portion. In one example, the dunnage tray is formed by thermoforming an extruded sheet to form the base portion and by attaching separately formed top portions with polyethylene elastomers, or plastomers to the thermoformed base portion. This invention provides solutions to chaffing or chipping of polyethylene dunnage trays, control of coefficient of friction and softness to minimize parts from sliding/abrading dunnage surfaces, and eliminates requirements for disassembly of dunnage trays and separation of materials prior to recycling.

A method for producing a well or a well strip made of plastic, as used in the pharmaceutical industry in microtiter systems is presented. The wells typically have undercuts and the well strips are connected to each other by connecting ribs. In order to produce a well with a larger undercut height or a well strip with higher connecting ribs, as the case may be, the method provides that the plastic, which is initially still liquid, is pressed through a portion of a runner which is arranged in a slider and out of the slider into a cavity of an injection mold.
