Degradable biodegradable film and preparation method thereof

Abstract

The invention discloses a degradable biodegradable film and a preparation method thereof. The method includes: a. adjusting the tension adjustment roller to the initial position; b. adjusting the first cylinder and the motor to the initial position; c. switching the state of the switching device; d. , cleaning traction roller and tension adjustment roller; e, hopper loading; f, blown film by blowing up; g, switching winding; h, switching coding. The invention can shorten the production line of the degradable biodegradable film, save the occupied area, and the tension adjustment of the degradable biodegradable film during the winding work and the tension control of the degradable biodegradable film during the coding work are all at the cross The central point of the cross design is convenient for the conversion of the tension adjustment of the biodegradable biodegradable film, which can not only ensure the smoothness of the degradable biodegradable film that is rolled up, avoid the phenomenon of folding, but also ensure the unwinding of the biodegradable biodegradable film. Spread out the whole width at a time, so that the coding is uniform, and the manufacturing quality of the biodegradable biodegradable film is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of plastic films, and in particular relates to a degradable biodegradable film and a preparation method thereof. Background technique [0002] Most of the traditional plastics have stable properties and are not easy to be rapidly degraded by various environmental factors in nature, so that there is a serious harm to the environment caused by waste plastics, that is, the so-called white pollution. Since the beginning of the 21st century, protecting the global environment, building a resource-recycling society, and taking the path of sustainable development have become global hot spots and urgent tasks. Biodegradable plastics can be digested and decomposed into carbon dioxide, water, other biomass and inorganic substances by microbial erosion in a short period of time, and are low-load materials for the environment. At present, the raw materials of biodegradable packaging films used in the market are mainly P...

Problems solved by technology

Generally, an inkjet printer is installed after the winding process, and the winding and inkjet operations are in a one-line design, and there are the following technical problems: (1) the production line for manufacturing the biodegradable film becomes longer and the floor space becomes larger; (2) due to The production line is long, which makes it difficult to control the tension of the film, causing the edge of the film to be folded when the jetting jet codes the film, which in turn leads to uneven coding and affects the manufacturing quality of the film
