30 Extrusion International 4/2023 30 INDUSTRY NEWS Separate Different Plastics by Density Herbold Density Separation Tanks or Sink-Swim Tanks use water to separate plastics of different densities in post-consumer recycling systems. They can also be used to separate contaminants from homogenous plastics. Items are introduced to the large steel tanks by a feed- ing screw or conveyor at one end. Three or four trans- port drums (rotating paddles) move the material from one end of the tank to the other. During this process higher density plastics like PET and PVC and/or contami- nants sink to the bottom of the tank while lower density plastics like PE and PP float on the surface of the wa - ter. Lighter plastics exit the tank via a top discharge and heavier items are continuously removed by a scraping chain conveyor mounted below the bottom of the tank. The tank’s V-shaped bottom helps to ensure that sink- ing waste can be exited from the bottom with no accu- mulation or build-up. Tanks are available in three sizes from 78” x 31” up to 157” x 71” with drive motors from 1.5 up to 15 hp. Throughputs vary depending on material and tank size. Herbold Meckesheim USA, a subsidiary of Herbold Meckesheim Germany, designs, manufactures, and in- stalls size-reduction equipment and wash line systems for the plastics industry, specializing in the recycling of industrial and post-consumer plastics. Components of the company’s systems are designed as modular “build- ing blocks” so that a system can be extended or modi- fied according to the customer’s requirements.

David Lefrancois, President www.herboldusa.com Packaging Innovations for Food and Beverage Customers at PACK EXPO Las Vegas BW Packaging, Barry-Wehmiller’s global team of packaging professionals, will showcase new food and beverage packaging innovations in booth C-1800 at PACK EXPO Las Vegas, held September 11 to 13. This year’s lineup includes new machines from some of the most trusted packaging brands in the industry, includ- ing Accraply, Angelus, Burt, Goldco, Graham + Sleevit, Hayssen, Hudson-Sharp, Pneumatic Scale, SYMACH, Thiele, Zepf and more. “PACK EXPO Las Vegas will be yet another display of BW Packaging’s people-centric approach to packaging innovation,” said Carol O’Neill, BW Packaging Group President. “We’re excited to unveil multiple new ma- chines, which were designed to address specific custom - er challenges, such as ergonomics, ease of operation and the environmental impacts of packaging, as well as many others.” To make it easy for customers to explore BW Pack- aging’s comprehensive range of solutions and brands, booth C-1800 will be organized in alignment with five lines of business: BWFlexible Systems, BWRigid Systems, BW Labeling, BW End-of-Line and BW Integration. BW Packaging companies Synerlink and Pneumatic Scale Angelus will be in the BW Rigid Systems portion of the booth, where Pneumatic Scale Angelus will debut its CB100R, the newest addition to its craft beverage can- ning portfolio. In the BWFlexible Systems area, the newHayssenMini vertical form-fill-seal (VFFS) bagger will run paper bags, specifically for customers needing to quickly shift all of their flexible packaging to recyclable paper material. In the BW Labeling (formerly Accraply) area, the new Graham + Sleevit direct feed (DF) and vertical feed (VF) series labelers will be operational. Both labelers were designed to address growing brand owner needs for labeling solutions that can run sustainable low-gauge films (PVC, rPET, PETG, OPS and PLA) for food, bever - ages, pharmaceuticals and several other product types. The much-anticipated Fortis Bulk Depalletizer by Goldco (patent pending), while not onsite, will be show- cased in the BW End-of-Line/BW Integration portion of the booth. Designed for optimal operator ergonomics and safety, the Fortis features a unique dunnage han- dling system that brings the consolidated dunnage down to floor level for easy robotic separation, an op - tion that did not previously exist in this size and price category. In the same area of the booth, visitors also will find examples of fully integrated packaging lines for food, beverages and a variety of other products.
