Extrusion International 2-2021

50 Extrusion International 2/2021 CHINAPLAS 2021 After the publication of the new Na- tional Standard for Cement Packing last October, block bottom valve bags made of coated PP tape fabric are highly sought after. Until March 2022 Chinese cement producers have to switch their packaging to one of the three cement sack types specified in the Standard. Among them: AD*STAR block bottom valve sacks made of plastic fabric, which have been developed and patented by the Austrian engineering company Star- linger. “Since it has been established that the Starlinger AD*STAR block bottom valve sacks meet the specifications of the Na- tional Standard, demand for them in China is skyrocketing”, says Herman Ad- rigan, Head of Sales at Starlinger. “We are delivering conversion lines for an ad- ditional 2 billion AD*STAR sacks to Chi- na until 2022. The focus of our division Starlinger textile packaging at Chinaplas will thus be on AD*STAR production technology, although unfortunately we cannot present the latest technological developments live on a conversion line during the exhibition.” A sustainable packaging for cement AD*STAR block bottom valve sacks are made of laminated polypropylene tape fabric using a specially developed weld- ing process. Contrary to blown film or kraftpaper, theplastic fabric is extremely durableandbreak-resistantandprotects the content from moisture. These char- acteristics make AD*STAR sacks a very sustainable cement packaging solution FDA (US Food and Drug Administration) approvals as well as by various brand owners. Starlinger also offers FDA-approved re- cycling solutions for the production of food grade regranulate from post-con- sumer HDPE packaging such as milk and beverage bottles. The regranulate can be used again in packaging for direct food contact. Nomore odours in recyclates Especially regarding post-consumer plastics, odours are a central topic. If for example HDPE packages of sanitary products are recycled, the produced regranulate frequently smells of the packaged liquids. This also often hap- pens with LDPE post-consumer films from household and agricultural waste. Starlinger’s odour extraction technol- ogy solves this problemby removing the substances that cause the odour – be- cause if they remain in the regranulate, unwanted smells can develop during the manufacture of new products. Star- linger C-VACmodules and odour extrac- tion units for effective odour reduction are being used successfully in many dif- ferent applications by now. Note: AD*STAR ® is a registered trademark. AD*STAR ® sacks are produced exclusively on Starlinger machinery. Starlinger & Co. Ges.m.b.H. Sonnenuhrgasse 4, 1060 Vienna, Austria www.starlinger.com Technologies for Cement Packaging and Plastics Recycling AD*STAR block bottom valve bags and post-consumer plastics recycling are the twomain topics that Starlinger & Co. GmbHwill focus on at Chinaplas in Shenzen, China because they help to reduce CO 2 emis- sions during cement production: Less cement loss caused by ruptured sacks or hardened cement in the course of the transport and logistics chain means that less cement needs to be produced for re- placement – and consequently, less CO 2 is emitted. Other important advantages of AD*STAR block bottom valve bags: • Perfectly suited for automatic filling and palletising • The polypropylene coating ensures tightness and avoids leaking of the product • Adjustable air permeability due to op- tional microperforation – reduces dust formationandprotects against humidity (improved shelf life) • Fully automated sack production on Starlinger ad*starKON conversion lines • Attractive sack design on all visible sur- faces for better brand advertising Concentrated know-how in post-consumer plastics recycling At this year’s Chinaplas, Starlinger re- cycling technology is focussing on post- consumer recycling. Be it post-consumer waste such as rigid plastic packaging, bottles, containers or films made of HDPE, PP, PE or PET – Starlinger has the recycling solution for it. In the field of PET recycling Starlinger is one of the leading technology providers: The PET regranulate producedon Starlinger lines can be used in applications with direct food contact, which has been confirmed by more than 50 positive EFSA opinions, Starlinger ad*starKON conversion line for AD*STAR ® block bottom valve sack production Starlinger at Chinaplas: 13. – 16.
