Block bottom valve bags made of woven plastic are not only a tear and moisture-resistant packaging for dry bulk goods – they are also becoming an increasingly sustainable packaging alternative in the construction sector.  
This year, Starlinger will be producing the Ad*Star block bottom valve sacks with 22% recycled content on the new sack conversion line ad*starKon SXneo on display at the company’s stand at the K 2022 trade fair in Düsseldorf/Germany from October 19-26, 2022. In this way, Starlinger & Co. Ges.m.b.H., Vienna/Austria, wants to show that it is possible to use recycled material in woven plastic packaging, which is manufactured in a complex process, without having to accept a loss of quality.
In addition, Starlinger’s new, patented gripTec technology, which will also be on show at the trade fair stand, can increase the coefficient of friction on the bag surface to significantly reduce slipping of stacked bags. This lowers the risk of personal injury from bags slipping down and saves tons of bulk material and packaging. Furthermore, the CO2 generated during replacement production is eliminated.
Starlinger lines can produce and process woven fabric not only with recycled polypropylene (rPP), but also with recycled polyethylene terephthalate (rPET).  
The circular packaging concept paves the way for a closed packaging cycle in the industrial sector. Industrial packaging such as big bags made of woven PP are equipped with a material passport that allows their life cycle to be traced from production and use to return and recycling. This means that new big bags can be made from used big bags without quality loss, and the packaging cycle can be closed. Big bags with rPP content produced by Starlinger customers will also be on display. The initiative “Verpackung mit Zukunft” (Packaging for the Future) will also be represented at the Starlinger stand, providing information to interested parties on the topic of circular economy.   
PET tape fabric is high-strength, food grade, has very good creep resistance and can be made from 100% recycled material. As with bottle-to-bottle recycling, this enables “bag-to-bag” recycling and closes the packaging cycle. This not only lowers raw material requirements, but also CO2 emissions and energy consumption. Both PET and rPET tape fabrics have already been used successfully in the production of big bags. Due to their very good dimensional stability, PET big bags are ideal for long-term storage of bulk goods and provide a cost-effective alternative to octabins and cardboard cylinders. As a mono-material solution, they can be recycled easily after use and can be reprocessed as often as desired.
