Promote environmental protection packaging film application to reduce white pollution

[China Packaging Network News] With the development and progress of society, people are paying more and more attention to protecting the environment that we depend on. The “white pollution” caused by non-degradable plastic waste is still severe. In this regard, Qingdao CPPCC members, Qingdao University of Science and Technology doctoral tutor, Professor Li Shaoxiang proposed to accelerate the application of environmentally friendly PVA water-soluble packaging film, so that Qingdao is more ecological and more environmentally friendly recommendations. It is understood that the water-soluble film is a water-soluble, biodegradable and novel green packaging material that uses a water-soluble polymer material that dissolves rapidly in water and is produced through a specific film-forming process. In addition to water solubility, polyvinyl alcohol (PVA) is characterized by good compactness, high crystallinity, and strong adhesion. The film made from it is not only flexible, smooth and non-chargeable, but also resistant to oil, solvent, and wear. Good gas barrier properties. PVA film is a product with high technological content and high added value. No matter whether it is raw material selection, processing or consumption process, it has no or no toxic or harmful substances, which is conducive to environmental protection and green consumption. It is an environmentally friendly product. Li Shaoxiang told reporters that water-soluble PVA films have received widespread attention from the developed countries in the world, and Japan, the United States, and France have produced and sold such products in large quantities, such as the American WTP company, CCLP company, France’s GRENSOL company and Japan’s synthetic chemistry, Cola Lee and so on. And its main market is also abroad. India is a big embroidery country. The demand for water-soluble films is concentrated in the embroidery industry; the demand for water-soluble films in Europe and the United States is mainly concentrated in the industries of isolation packaging, machine packaging, and release film, and the market is relatively mature, especially hospital laundry. Bags, chemicals and pesticide packaging bags, pet feces bags, "machine-coated" and other large quantities; protective foaming products and small electrical appliances bags are still in the promotion period, but the prospects are excellent. The annual growth rate of PVA film in the world is 8% to 10% in the next few years. Therefore, the entire water-soluble packaging film market is very large. “In China, the water-soluble film market is just starting to flourish. China's medical, chemical, electrical, and toy industries are all well-developed. The market for water-soluble packaging films has broad prospects.” Li Shaoxiang said that Qingdao is a fast-growing city, especially for tourism and tourism. Mainly in home appliances manufacturing, medical, food, mold, and other industries have also developed rapidly. In order to reduce white pollution and improve Qingdao's urban environment, it is recommended that supermarket shopping bags, hospital laundry bags, chemical and pesticide packaging bags, small electrical appliance packaging bags, machine packaging film applications, protective foaming products, and release film applications Other areas focus on the application of water-soluble PVA films.
