Starlinger at Chinaplas 2025
Starlinger & Co GmbH puts the focus on its technologies for sustainable and efficient polypropylene tape production as well as food-safe recycled PET and polyolefins at Chinaplas this year.
With a maximum melting capacity of 1000 kg per hour and production speeds of up to 550 meters per minute, Starlinger’s starEX 1600 tape extrusion line unites high efficiency with resource-saving state-of-the-art design. It produces top-quality PP or HDPE/LLDPE tapes for high-performance packaging applications for dry bulk goods such as woven PP sacks or big bags. Specially developed and worldwide unique machine components such as the eqoSTRETCH stretching and annealing system ensure energy-saving production and uniform tape characteristics, while the eqoCLEAN filter system enables the processing of high shares of recycled polypropylene for producing more sustainable woven PP packaging.
“We have gathered decades of expertise both in woven plastic packaging production as well as in plastics recycling,” said Harald Neumüller, Chief Sales Officer at Starlinger. “By combining this know-how, we have developed technology that helps packaging manufacturers to establish closed packaging loops and make plastic packaging circular.” Starlinger has already realised lighthouse projects with customers in the FIBC sector, proposing a closed-loop economy for big bags made from rPP and rPET. “We consider used plastics as a resource, not waste,” Neumüller continued. “This is the only way to get a grip on the increasing amount of plastic waste worldwide. By collecting used plastics and reprocessing it we protect our environment, conserve natural resources, and at the same time save money that would need to be spent for waste treatment facilities and environment clean-ups.”
Precision to the core
With its high-speed winding technology, the twinTAPE+ automatic precision winder is Starlinger’s top-scale tape winder model. It ensures that the produced PP tapes from the starEX tape extrusion line are wound into perfect packages that improve productivity and fabric quality on the looms. The bevelled bobbin edges avoid that tapes come off during doffing, transport and handling and increase loom efficiency during weaving. The automatic bobbin change procedure of twinTAPE winders reduces operator work significantly, and the patented linear traverse system features an infinitely variable stroke, allowing a wide variety of bobbin designs. As the winder does not need lubrication, maintenance work is reduced to cleaning, which saves significant amounts of operator time.
Post-consumer recycled plastics go food-grade
When it comes to turning post-consumer plastic scrap into top-quality recycled materials that meet highest food safety criteria, the Starlinger division Starlinger recycling technology offers well-proven technical solutions.
Starlinger’s recoSTAR PET art PET bottle-to-bottle recycling systems produce rPET with highest purity and ultra-low levels of acetaldehyde, ethylene glycol and VOCs (volatile organic compounds) while featuring low energy consumption and a compact footprint. The Starlinger PET recycling process has been approved by national and international authorities such as FDA and EFSA for its food safety, and many multi-national brandowners rely on rPET produced on Starlinger recycling systems for more sustainability in their packaging solutions.
With the versatile recoSTAR dynamic product line, Starlinger offers a proven system for the challenging task of food-grade recycling of post-consumer HDPE packaging. High-performance cascade degassing in the C-VAC module, combined with ozone-enhanced air flushing in the PCUplus unit at the end of the recycling process ensure best decontamination results and food-safety for food packaging made from HDPE such as bottles and caps.
