Abstract
The invention aims to provide a resin modification and preparation method for producing a wrapping film from a biodegradable material. An industrially applied degradable wrapping film is produced from a biodegradable material, so that the technical problem and the production process problem for producing a wrapping film from a full biodegradable material are solved, and meanwhile, the problem that the environment is polluted by using a wrapping film is also solved. The invention relates to a resin modification and preparation method for producing a wrapping film from a biodegradable material. The used materials comprise the following components in parts by weight: 2-10 parts of polylactic acid (PLA); 90-98 parts of poly (butylene adipate-co-terephthalate) (PBAT); 2-5 parts of nano calciumcarbonate; 0.2-0.5 parts of octadecyl acrylate-maleic anhydride; 0.2-0.6 parts of a chain extender; 0.2-0.8 parts of an antioxidant; and 0.2-0.5 parts of a lubricant. The method has the beneficial effects that firstly, the raw materials are fully biodegradable materials and are environment-friendly; and secondly, part of materials are modified, PBAT on the inner side does not need to be modified again and is directly produced, and damage to the molecular structures of the raw materials can be reduced.
Description
technical field [0001] The invention provides a resin modification and a preparation method for producing a stretch film from a biodegradable material, belonging to the field of packaging materials. Background technique [0002] Stretch film, also known as stretch film and heat shrinkable film, has good tensile, puncture and tear resistance, good self-adhesiveness and high elongation, and is widely used in the packaging field. At present, stretch film is mainly used in the sales and transportation of various products. The raw material is petrochemicalpolyethylene. Polyethylene is a thermoplasticengineering plastic with a linear structure and excellent overall performance. It develops rapidly and has a large amount of use. It pollutes the environment and cannot be degraded for 300 years. In view of this, a resin modification and its preparation method for producing stretch film with biodegradable materials are urgently needed in the industry. The existing stretch film is a...
