“The raw material and the fine filament webs are fully biodegradable and compostable,” explained Mike Black, general manager, Food Nonwovens. “An independent LCA (life cycle assessment) carried out to ISO 14040 standards demonstrated that these webs have a lower carbon footprint compared to similar products made of oil-based polymers.” The principal ingredient is PLA (polylactic acid), a biopolymer currently derived from cornstarch. This also means that the raw material for this product is based on 100% annually renewable resources.
Suitable for conversion on tea packing machines that use ultrasonic sealing technology, the new materials complement Ahlstrom’s range of traditional heat sealable and non-heat sealable filter webs for tea and coffee. With manufacturing both in Europe and North America, Ahlstrom now offers a broad range of beverage filtration materials.
Ahlstrom infusion materials are part of the company’s Advanced Nonwovens business area and are sold globally through the Ahlstrom sales network.
