14 Feb 2019 --- Two major packaging suppliers are responding to growing demand for plastic-free straws. Beverage carton supplier SIG has launched an FSC-certified paper alternative which can be recycled via existing paper recycling streams. It is made from three layers of paperboard and two layers of adhesive. Food packaging supplier Huhtamaki’s PEFC-certified paper straws, meanwhile, are made of fiber sourced from sustainably managed forests.
