core tip: with the development and progress of society, people pay more and more attention to protecting the environment we rely on, while the "white pollution" caused by non degradable plastic waste is still serious. In this regard, Li Shaoxiang, a member of the Qingdao Municipal Committee of the Chinese people's Political Consultative Conference and doctoral tutor and professor of Qingdao University of science and technology, proposed to accelerate the application of environmentally friendly PVA water-soluble packaging film, so as to make Qingdao more ecological and more environmentally friendly after a period of use

[China Packaging News] with the development and progress of society, people pay more and more attention to protecting the environment on which we live, while the "white pollution" caused by non degradable plastic waste is still serious. In this regard, Li Shaoxiang, a member of the Qingdao Municipal Committee of the Chinese people's Political Consultative Conference and doctoral tutor and professor of Qingdao University of science and technology, put forward suggestions to accelerate the application of environmentally friendly PVA water-soluble packaging film and make Qingdao more ecological and environmental friendly

it is understood that the water-soluble film is made of water-soluble polymer materials that can be quickly dissolved in water through a specific film-forming process. It is a water-soluble, degradable and novel green packaging material. In addition to water solubility, polyvinyl alcohol (PVA) has the characteristics of good compactness, high crystallinity and strong adhesion. 1. The equipment should be placed in a special room. The film made of PVA is not only flexible and smooth, non charged, but also oil and solvent resistance, wear resistance and gas permeability. The veil of the "13th five year plan" of new materials is gradually lifted. PVA film is a product with high scientific and technological content and high added value. No matter the selection of raw materials, or the processing and consumption process, it does not release toxic and harmful substances, which is conducive to environmental protection and green consumption. It is an environment-friendly product

Li Shaoxiang told that water-soluble PVA film has been widely valued by developed countries in the world. Japan, the United States and France have produced and sold such products in large quantities, such as w.t.p company and company in the United States, gransol company in France, synthetic chemistry and cola company in Japan, etc. And its main market is also abroad. India is a big country in embroidery. The fair and correct use of fixtures is conducive to the smooth progress of the experiment. The demand for water-soluble films is concentrated in the embroidery industry; The demand for water-soluble films in European and American countries is mainly concentrated in the industries of isolation packaging, machine packaging, demoulding film, etc., and the market is relatively mature, especially the large amount of laundry bags for hospitals, chemical and pesticide packaging bags, pet feces bags, "machine packaging" and so on; The application of protective foaming products and small electrical appliance packaging bags are still in the promotion period, but the prospect is excellent. In the next few years, the annual growth rate of PVA film in the world is 8% - 10%. Therefore, the whole water-soluble packaging film market is very huge. "In China, the water-soluble film market is in the ascendant. China's medical, chemical, electrical, toy and other industries are very developed, and the market prospect of water-soluble packaging film is broad." Li Shaoxiang said that as a rapidly developing city, Qingdao is mainly engaged in tourism and home appliance manufacturing, and its medical, food and mold industries are also developing rapidly. In order to reduce white pollution and improve the urban environment of Qingdao, it is suggested to focus on promoting the application of water-soluble PVA film in supermarket shopping bags, hospital laundry bags, chemical and pesticide packaging bags, small electrical appliance packaging bags, film application for machine packaging, protective foaming products application, demoulding film application and other fields
