Problems solved by technology
At present, with the development of social economy, people's awareness of environmental protection is getting higher and higher, and the problem of white pollution caused by plastic waste is getting more and more attention. It is difficult to be degraded by microorganisms and can exist for hundreds of years, causing great damage to the ecological environment
[0003] At present, in order to solve the environmental pollution problems caused by traditional plastic packaging films, many packaging films with biodegradability have been developed. However, many packaging materials used to replace traditional plastic films only show good degradability. Water resistance, oil resistance, gas barrier and thermoplasticity are poor, and the tensile strength and tear strength of the film are not high, resulting in poor sealing performance, which cannot meet people's needs well; in addition, the preparation method is old and the production efficiency is low. High cost, does not meet production and use requirements

Embodiment
[0020] The specific preparation method is as follows:
[0021] a) Dissolving polyvinyl alcohol, the specific preparation process is: first prepare the dissolving device, the dissolving device includes a dissolving furnace, an electric stirrer and a constant temperature water bath, wherein the dissolving furnace is placed in a constant temperature water bath, the temperature of the constant temperature water bath is 80 ℃, electric stirring The device was installed in the dissolution furnace; then the polyvinyl alcohol was put into the dissolution furnace and dissolved in deionized water to prepare a 6% polyvinyl alcohol solution. The polyvinyl alcohol has excellent transparency and gloss, high tensile strength and tear strength, good oil resistance, gas barrier property, heat sealing property and adhesive property.
[0022] b) Polyvinyl alcohol modification treatment, the specific preparation process is as follows: first, borax, urea and glycerin are sequentially added to the p...

The invention provides a novel packaging film capable of replacing a conventional plastic film and a preparation method of the novel packaging film. The novel packaging film comprises ingredients of polyvinyl alcohol, sodium borate, urea and glycerinum. The preparation method of the novel packaging film comprises steps as follows: a), dissolution of polyvinyl alcohol; b), modified treatment of polyvinyl alcohol; and c), film preparation and aftertreatment. The invention discloses the novel packaging film capable of replacing the conventional plastic film and the preparation method of the novel packaging film. The novel packaging film preparation method is simple, the production cost is low, and the novel packaging film has higher degradation rate, excellent water resistance, higher strength, excellent thermoplasticity and broad application prospect.
Description
technical field [0001] The invention relates to a plastic product, in particular to a novel packaging film which can replace a traditional plastic film and a preparation method thereof, belonging to the technical field of plastics. Background technique [0002] With the advancement of science and technology and the development of the plastics industry, various plastic products are widely used in various fields of social production and life, among which plastic packaging film is one of the most widely used plastic products.
