in Germany, prompted by customer demand. The new recycling innovation centre will be built
next to its existing test centre for bulk solids handling. At the facility, customers will be able to develop and test new, sustainable products and recycling processes with Coperion experts. All recy- cling stages will be covered at the facility including conveying, feeding, extrusion and post-processing. Coperion will also conduct its own research into plastics recycling at the centre. “Worldwide demand for efficient plastics
Above: Davis- Standard’s lab line has helped SCG test polymer formulations for packaging
SCG Chemicals. It has helped the company test existing SCG resins for aseptic packaging and to test new resins for applications such as liquid packaging, flexible packaging, woven coating and tarpaulins. “We chose Davis-Standard because of their
expertise in extrusion coating and ability to customise the line four our specific requirements,” said Niwat Athiwattananont, technology and product development director for the polyolefins and vinyl business at SCG. SCG has run extrusion and adhesive lamination
trials, including autoclave LDPE resins for high- speed coating and seen consistent stability during PE and PP film runs.
SCG combined dry lamination capabilities into one machine for extra versatility, while maintaining the high-speed coating needed for demonstrating resins used in aseptic applications. “We can now expedite our R&D efforts and
production development by proving resin perfor- mance prior to customer trials,” he added. Daniel Schiller, area sales and project manager for Davis-Standard, added: “The innovation being delivered on this new line is significant for Thai Polyethylene’s customer base.” Davis-Standard has also developed a compact
extruder for extrusion coating applications. The CHP claims to offer a smaller footprint and lighter weight to allow for easier addition to an existing carriage or platform structure. This gives processors a space-saving replacement or coextru- sion addition for increasing outputs and line speed, said the company. Davis-Standard has a CHP extruder in its
laboratory, on which customers can run trials and validate processing conditions before purchase.

recycling solutions will continue to grow because of the increasing demands of environmental legislation,” said Markus Parzer, managing director of Coperion. The new addition expands the company’s test lab capacities in Germany alone by around 5,000 sq m. Marina Matta, team leader of process technology engineering plastics at Coperion, added: “We are offering our customers a top-tier solution for developing their processes and products. Along with processing and product solutions for mechanical recycling, we can also develop and test innovative solutions for every other current recycling process.”
LCP line
Labtech Engineering says it has developed a laboratory and pilot plant blown film line to process liquid crystal polymers (LCPs). The line, called LF-600/LCP, features a 30mm single-screw extruder with special screw, a drying hopper, a tri-rotating die (TRD) with spiral flow distribution channels and a dual-lip air cooling ring. This is followed by a three-zone annealing chamber for cooling and eliminating residual stress in the film bubble. The TRD orients the melt in multi-axial symmetry, which balances out residual stresses, says the company. It was designed in-house and can produce a film with a maximum lay-flat width of 500mm. The line is also equipped with a dual set of aluminium collapsing A-frames, tower nip rolls with water cooling, edge trimmer, haul-off rubber nip rolls, film web tension controller and a two-station surface winder. LCPs are anisotropic polymers that are typically used in electronics, anti-corrosive liners and high barrier films.
