Moisture barriers often force customers to compromise on the productivity of the filling process, but with these new concepts all that has changed."The end customer focus has been the driving force behind the development of Billerud's new sack solutions for products such as construction materials and industrial minerals in powder form," explains Johan Nellbeck, Business Area Director, Packaging & Speciality Paper, Billerud.QuickFill BioTex is one of the paper sack concepts with a moisture protection made from bioplastic from Billerud's subsidiary Billerud Tenova Bioplastics. The moisture protection is manufactured from a renewable raw material derived from cornstarch. All the components of QuickFill BioTex are both biodegradable and compostable."We are very pleased with the tests at Billerud's Sack Lab in Karlsborg and the trial runs and functionality tests at customer sites, which showed that all five of the sack designs offer added value and work extremely well," says Nellbeck.
