Cement block bottom sack

Starlinger, Austrian machine manufacturing company based in Vienna, focuses on the Chinese market to spread its entire machinery range for the production of sustainable woven plastic packaging and recycling of post-consumer and in-house plastic scrap.

“As the demand for AD*STAR (block bottom sack made without adhesives from coated polypropylene fabric) cement bags is very high in China, our focus is on the production technology for them - starting with our tape extrusion lines and winders as well as the lamiTEC coating technology, which, among others, is crucial for AD*Star block bottom valve bag conversion”, declared Hermann Adrigan, Sales Director of Starlinger. The coming into force of the Chinese Standard on cement packaging has led to an ongoing demand for AD*Star sacks in China during the past two years. The new standard permits only three types of sacks for packaging cement in order to improve sustainability and resource conservation and must be implemented without exception by March 2022. AD*Star block bottom bags, developed by Starlinger and made of coated polypropylene tape fabric, feature a favourable carbon footprint, an extremely low breakage rate, and protect the cement against humidity. The accurate conversion process on the Starlinger ad*starKON sack conversion lines guarantees smooth filling of the sacks on the most modern filling lines.

Furthermore, now Starlinger recycling technology puts the spotlight on PET recycling and odour reduction for post-consumer recycled plastics. “China is one of our most important markets in Asia. The reprocessing of PET bottles as well as the re- and up-cycling of other post-consumer plastics such as PE and PP are topical issues in the area of plastics recycling”, said Paul Niedl, Commercial Head of the business unit.
