Disclosed is a dip-coating method as a method of coating an outer surface of a target mold including steps of: preparing and putting a supporting liquid in a container; applying a coating material to the target mold; dipping the target mold in the supporting liquid; shaking the target mold surrounded by the coating material in the supporting liquid; curing the coating material surrounding the target mold in the supporting liquid; and taking out the coated target mold from the supporting liquid.

An extruder for multi-lumen tubular products with multi-coronal arrangement comprises a main body (2) defining a passage cavity (2a) and an average outflow direction (2b), as well as an input surface (3) and an exit surface (4) respectively formed on opposite faces of the main body (2) and defining respective entry areas afferent to and efferent from the passage cavity (2a); the extruder further comprises an expansion portion (4a) associated with the exit surface (4) and adapted to mutually orient spontaneous expansive flows of said extrusion material through the exit surface (4) in reciprocal directions of mutual intersection.

The present invention relates to a film wrapping machine for a product packing device using a stretch film, including a frame having vertical bars extending upward and spaced apart from each other, a film clamping unit including a pair of suction pads which are moved in a direction of being spaced apart from each other in a state of adsorbing the stretch film so that a front end portion of the stretch film supplied from a film supply device is opened, and a plurality of clamps configured to grip the front end portion of the stretch film opened by the suction pads, receive the stretch film whose upper end is cut and bonded by the film supply device in a wrinkled state, and process the stretch film to be covered on a product in a process of lowering the vertical bars, and a controller which controls operation of the film clamping unit and the film supply device.

A method for manufacturing an arrangement for the transport of media includes a base body formed as a blow-molded part and at least one functional element, in which a preform consisting of polymeric material and at least one functional element are provided and arranged in a blow mold, wherein the base body is formed from the preform, wherein the preform bears against the functional element during forming, wherein the blow mold has a first mold element and a second mold element, wherein the base body is formed from the preform between the first mold element and the second mold element, wherein the first mold element and the second mold element bear against the functional element in such a way that excess material produced from the preform in the area of the functional element during blow molding can be removed.

This disclosure describes co-extruded multilayer articles including at least one continuous layer and one discontinuous layer, as well as systems and techniques for the manufacture of co-extruded multilayer articles. For example, a co-extruded multilayer article is described that includes a body having a plurality of layers, where a first layer of the plurality of layers is formed from a first material and is continuous along a longitudinal axis of the body, and a second layer of the plurality of layers is formed from a second material and is discontinuously co-extruded along the longitudinal axis.

The disclosed technology relates to a plastic compound suitable for preparing articles, such as pipe fittings and valves, with good physical properties, such as impact strength, and resistance to environmental stress cracking (ESC). In particular, the technology relates to a vinyl chloride resin, which includes chlorinated polyvinyl chloride (“CPVC”) homopolymer. Furthermore, the invention relates to vinyl chloride homopolymer compounds containing the vinyl chloride homopolymer resin, and articles made from such compounds, which compounds meet 23447 cell classifications under ASTM D1784.

Provided herein are liners, for example, for storing or dispensing high purity chemicals, as well as methods of manufacturing such liners. The liners resist formation of stress-induced breaches. In one aspect, the liner includes a film formed into a liner capable of retaining a liquid. The liner has a first barrier layer to a gas (e.g., oxygen); a second barrier layer to the gas (e.g., oxygen); and at least one additional layer of material disposed interstitially between the first barrier layer and the second barrier layers.

A device for providing a tubular foil comprises a frame (5) with a position for an active product holder (P4) from which the tubular foil (10) can be removed and at least one further position (P1-P5) for at least one subsequent product holder with a subsequent tubular foil (20). The device provides coupling means for attaching a leading end (25) of the subsequent tubular foil (20) to a tail end (15) of a spent tubular foil (10). The coupling means comprise a carriage (110) with a drivable applicator device (100). The applicator device comprises a set of opposite applicator members (130) with mutually facing operative surfaces (135) and can be manipulated between a spread position, wherein the operative surfaces lie removed from each other, and a clamping position wherein the operative surfaces lie clampingly on each other. The applicator device (100) further comprises supply means for providing adhesive strips (60) in the spread position, and can be controlled to bring the applicator members (130) with the adhesive strips (60) into the clamping position, with interposing of the tail end (15) of the spent tube (10) and the leading end (25) of the subsequent tube (20), in order to mutually connect the ends (15, 25), and to bring the applicator members into the spread position in order to release the ends with the adhesive strips.

Polypropylene mono-layer films produced with blown film or cast film technology comprising a blend of: a) 75.0 to 98.0 wt %, based on the blend, of a random propylene copolymer and b) 2.0 to 15.0 wt %, based on the blend, of an ethylene based plastomer having a density according to ISO 1183D of 0.915 g/cm.sup.3 or below and an MFR.sub.2 according to ISO 1133 (190° C.; 2.16 kg) in the range of 2.0 to 30 g/10 min, wherein the film has simultaneously improved optic properties as well as tear resistance compared to random propylene copolymer based films without ethylene based plastomer.
