Resumen de: WO2025080158A1
The invention relates to the field of organic high-molecular-weight products, and more particularly to a film, and can be used as a production material and/or a packaging material. A biodegradable industrial film containing starch, polyvinyl alcohol and calcium carbonate is characterized in that said components are present in the following quantities: 55-59.1 wt.% starch; 40-44 wt.% polyvinyl alcohol; 0.85-0.9 wt.% calcium carbonate. The technical result includes rendering the film less noisy in use, reducing the decomposition time of the film, increasing the strength properties of the film, providing enhanced shock-absorbing properties to protect a packaged object, and achieving an almost complete reduction in moisture permeability.
