A hollow body molding device forming a hollow molded body in a main cavity of a mold having in its one end a pressure port including a floating core by injecting molten resin through an injection gate into the main cavity having an outlet, and then pressure-injecting pressurized fluid through the pressure port into the main cavity to move the core toward the outlet through the resin injected into the main cavity to extrude the resin through the outlet and discharge it into a waste cavity, the device having: a floating core accommodating portion located between the outlet and a communication passage leading to the waste cavity and adjoins the main cavity and accommodates the core moved to the outlet by the fluid, in the device, a floating core accommodating portion inside diameter is smaller than a main cavity outlet diameter and is larger than a floating core outside diameter.

A manufacturing method of a polishing layer is provided. First, a mold for which the mold cavity has a contour pattern is provided, and the cross section of the contour pattern along a direction includes a plurality of recessions and at least one concavity portion, wherein the at least one concavity portion is disposed on the bottom of at least one of the recessions. A polymer material is disposed in the mold cavity. The polymer material is cured to form a semifinished product, wherein the cross section of the semifinished product along the direction includes a plurality of polishing portions corresponding to the recessions and at least one protruding portion corresponding to the at least one concavity portion. A flattening process is performed on the semifinished product to remove the at least one protruding portion.

Disclosed herein are methods of making active, food-grade packaging resins using a reactive extrusion step that involves reacting a polymeric material with a ligand and one of a cross-linking agent and a radical initiator in an extruder, under temperature and pressure conditions effective to cause covalent binding of the ligand to the polymeric material by a linker that is the reaction product of the cross-linking agent or by direct bond formation between the ligand and the polymeric material, and then extruding the active, food-grade packaging resin. Also disclosed are the active packaging resins obtained from such methods, methods of forming food packaging materials from the active packaging resins, the food packaging materials that contain the active packaging resins, and methods of packaging perishable food in those food packaging materials.

A device for producing plastic containers (10) by means of a molding, filling and sealing process is disclosed, at least consisting of a molding device (16) having individual molding tools (18), which can be moved repeatedly relative to one another from an open receiving position into a molding sealing position, and an extrusion unit (12), which can be used to insert at least one extruded plastic hose (14) into the open receiving position of the molding tools (18), which is characterized in that a traversing unit (20) can be used to move the extrusion unit (12) in conjunction with each extruded plastic hose (14) in opposite directions with respect to the molding device (16), which is stationary in every position of the molding tools (18).

A device (100) for providing a tube arranged or arrangeable in a circumferentially closed manner around a prolate object (102), preferably around a conductor, as a marking (101) of the object (102) is described. The device (100) comprises a printer (200) for outputting a printed tube (214) in longitudinal direction (210) or a material interface (156) for receiving a printed tube (214) output from a printer (200) in longitudinal direction (210). Further, the device (100) comprises a cutting unit (120) configured to cut through the printed tube (214) at a cutting position of the tube (214) in a transverse direction (121) transverse, preferably perpendicular, to the longitudinal direction (210) of the tube. At least at the intersection, an upper half of the tube and a lower half of the tube, terminally or insidely, abut on each other or are connected to each other. Further, the device (100) comprises an opening unit (122) for opening the upper and lower halves of the tube. The opening unit comprises at least two opening rollers (123), each rotatable about a rotational axis (123A). The respective rotational axis (123A) is perpendicular or substantially perpendicular to the longitudinal direction (210) and the transverse direction (121). The at least two opening rollers (123) abut against the cut and printed tube on opposite sides in the transverse direction (121).

A polypropylene composition comprising the following components in parts by weight: 40-99 parts of a polypropylene resin; 15-30 parts of an ethylene-α olefin copolymer; 0.2-1 part of an antimicrobial agent; and 1-3 parts of a polypropylene grafted polydimethylsiloxane is provided.
