Novel low-carbon degradable sheet material and product thereof

Abstract

The invention discloses a novel low-carbon degradable sheet material, thickness of which is within 0.01-0.15 mm. the sheet material is composed of 20-80 wt% of a plastic material, 10-70 wt% of a biobased material and 1-10 wt% of a biodegradation aid. The plastic material is a petrifaction- or plant-source plastic material. The biobased material contains starch, plant fiber powder or a composition of starch and plant fiber powder. The biodegradation aid contains polyolefin resin, ferment or microbes and related nutrient composition. Degradation rate of the novel low-carbon degradable sheet material is at least 90%.

Description

technical field [0001] The invention relates to a degradable sheet, in particular to a degradable sheet with low carbon production after degradation. Background technique [0002] Although plastic materials from petrochemical sources are widely used in daily necessities, with the gradual reduction of petroleum raw materials, the enhancement of the greenhouse effect, and the fermentation of environmental pollution caused by plastic materials that cannot be decomposed, the use of petrochemical plastics should be reduced or the development of degradable plastics Plastics have become a new development trend of plastics, and bioplastics have also emerged as the times require. At present, bioplastics can be divided into two categories, one is bio-based plastics, and the other is biodegradable plastics, which means that some or all of the plastics are obtained from renewable biological sources, and the other is biodegradable plastics. The purpose is to replace or reduce the use of...
