A system for handling used packaging film in a food processing facility is provided. The system stores the used film in a refrigerated truck trailer at the food processing facility to prevent rotting, prior to transporting the film to a treatment facility where the film may be recycled.

The invention relates to a polymer composition comprising a polyethylene and a crosslinking agent, characterized in that the polymer composition contains a total amount of vinyl groups which is B vinyl groups per 1000 carbon atoms, and B.sub.1≤B, wherein B.sub.1 is 0.88, when measured prior to crosslinking according to method ASTM D6248-98; and in that the crosslinking agent is present in an amount which is Z wt %, based on the total amount (100 wt %) of the polymer composition, and Z≤Z.sub.2, wherein Z.sub.2 is 0.30, an article being e.g. a cable, e.g. a power cable, and processes for producing a polymer composition and an article; useful in different end applications, such as wire and cable (W&C) applications.

The invention provides a cover tape and the method for manufacturing the same. The cover tape comprises an antistatic layer, two intermediate layers, a base layer, two tie layers and a heat seal layer. These seven layers are formed by a co-extrusion process.

The present invention relates to a method for removing a foreign material from the surface of an article comprising the following steps: i) providing an article having a surface covered at least partly with a foreign material; ii) contacting the article provided in step i) with a cleaning medium being an acid having a pKa in the range from −10 to 7 having a minimum concentration of 1 wt.-% and with a carrier medium having a density different from the density of the cleaning medium to obtain a mixture comprising the foreign material solved and/or dispersed in the cleaning medium, the carrier medium and the article free from the foreign material; iii) allowing the mixture obtained in step ii) to separate to obtain a heterophasic emulsion comprising at least a first phase comprising the carrier medium and the article free from the foreign material and a second phase comprising the cleaning medium and the foreign material solved and/or dispersed therein; iv) separating the phases obtained in step iii); and v) separating the article free from the foreign material from the carrier medium. Furthermore, the present invention relates to an installation for carrying out the inventive process.

Two workpieces 30, 40 are joined by means of ultrasound. First, a workpiece 30 with at least one energy direction sensor 31 and a second workpiece 40 are provided. The workpieces are brought into contact with each other in such a way that the energy direction sensor 31 comes into contact with a first surface 41 of the second workpiece 40. Ultrasonic vibrations are then introduced into one of the workpieces 40 via a working surface 11 of a sonotrode 10. A sonotrode 10 is used, which has a contour with contact lines 12 on the working surface 11. The sonotrode 10 is positioned with respect to the first workpiece 30 in such a way that the contact lines 12 run transversely to the energy direction generator 31.

A system for simultaneously forming and filling a polymeric container with a product. The system includes a mold defining a container profile and a mold vacuum vent extending from the container profile to an upper surface of the mold. A striker plate is secured to the upper surface of the mold. The striker plate defines a striker vacuum vent that aligns with the mold vacuum vent to allow some of the product to be pulled by vacuum out of the mold through the mold vacuum vent and the striker vacuum vent.

Disclosed are compositions and methods for multilayer films, which, in one embodiment may comprise a core layer comprising at least 50 wt. % of high-density polyethylene. Further, the multilayer film may include a first skin layer comprising at least 80 wt. % of high-density polyethylene, and a second skin layer comprising either: (i) one or more low-density polyethylenes; or (ii) one or more polypropylene-based copolymers. The multilayer film may be oriented in at least one direction.
