Eco-friendly double-sided sealing tape

1 min read

Steratape has launched BioTape which, says commercial director Carl Morris, is believed to be the world's first biodegradable and compostable double-sided sealing tape.

The product is made from two distinct functioning parts: First, the adhesive is a modified acrylic copolymer that has been formulated to include a high content of renewable (non-fossil derived) material. The company reports that trials have shown that good performance is achieved when used on existing biodegradable filmic bags. Second, the film that carries the adhesive is made from polylactic acid. The raw material for making this is corn starch and it is, therefore, a fully renewable resource. Trials have indicated that the film will heat-cut without difficulty in the bag-making process. The adhesive has accreditation to the international standard for biodegradability/compostability - EN13432. The film holds the accreditation to EN13432-2000-12 at 58ºC. Polybag manufacturers have been able to develop films that are biodegradable based on natural substances such as cellulose, Carl Morris points out. "However, until now it has not been possible to offer a self-seal bag since the adhesive tapes available have never been biodegradable. "Now the new Steratape product makes it possible for this fast-growing market to have a truly ecologically-friendly range of flexible packaging products for the first time."
