New Green Packaging Material——High-tech Water-soluble Plastic Packaging Film

October 05, 2019

As a novel packaging material, high-tech water-soluble plastic packaging film is widely used in Europe, the United States and Japan, and is widely used for packaging of products used in water, such as pesticides, chemical fertilizers, pigments, detergents, and water treatment agents. In order to fully understand the material composition, characteristics and application prospects, this article will briefly introduce this. 

The high-tech water-soluble packaging film mainly uses polyethyl alcohol as the main raw material, and adds various additives such as surfactants, plasticizers, anti-sticking agents, etc., and the process is different from the traditional plastic film forming process. The process is as follows: the raw material is first made into a water-soluble adhesive with a solid content of 18-20%, and then flowed onto a mirror stainless steel belt, dried and peeled from the steel belt, and then dried in a drying chamber. After prescribed moisture, cut the roll to obtain a finished film. Its main features are: environmental protection and safety, complete degradation (10%), and the final products of degradation are CO 2 and H 2 O, which can completely solve the problem of disposal of packaging waste; it is safe and convenient to use, and prevents users from directly contacting the packaged materials. It is suitable for the packaging of human body harmful substances, can accurately measure and prevent waste; it has good mechanical properties and high heat seal strength; it has anti-counterfeiting function, and is the best weapon for anti-counterfeiting of high-quality products, and can prolong the life cycle of high-quality products.
As a green packaging material, the film has been recognized in Europe, America and Japan. At present, BOD and COD are used as environmental protection indicators at home and abroad. Japan's relevant departments to determine the biodegradation of polyethylene acid 5 can be measured after the BOD amount is less than 1% of the initial total BOD. Through biological tests, it has been shown that polyvinyl alcohol is neither toxic nor inhibits the growth and reproduction of microorganisms, and has no effect on wastewater treatment and environmental hygiene. The study of microbiological decomposition of the relevant departments also showed that the polyvinyl alcohol was almost completely decomposed and the COD was lowered to a very low level.
As far as the degradation mechanism is concerned, polyvinyl acid has both water and biological degradability. It is first dissolved in a water-like glue solution and penetrates into the soil to increase the stickiness and air permeability of the soil, and is particularly suitable for the sand soil transformation. The PVA in the soil can be decomposed by bacteria isolated from the soil, ie strains of the genus PSEUDOM ONAS. A symbiotic system composed of at least two bacteria can degrade polyvinyl alcohol: one is an active bacterium of polyvinyl alcohol, and the other is a bacterium that produces substances required for PVA-active bacteria. The oxidation of secondary alcohol catalyzes the PVA, and then the hydrolase cleaves the oxidized PVA backbone, further degrades, and eventually degrades to CO 2 and H 2 O.
The water-soluble film has a wide range of uses, a very broad market, and environmental protection, and has therefore received wide attention from developed countries in the world. For example, Japan, the United States, and France have mass-produced and marketed such products, such as the United States’ W. T. P company, France's GREENSOL company and Japan's synthetic chemical company, its users are also some well-known large companies, for example, BAYET, H ENKEL, SHELL and other large companies have begun to use water-soluble film to package their products.
In China, the market for water-soluble thin films is on the rise. In terms of the domestic market, according to relevant statistical data, it is currently required that packaging films account for 20% of Plastic Products, which amounts to approximately 30.9 million tons per year, even if the market share is 5%. The annual demand is also 15,000 tons. In terms of economic benefits, it is also very significant, the cost of water-soluble film is about 2.9 to 32,000 yuan / ton, the current market price: US products for 130,000 yuan ring / ton, Japanese products for 20-25 Ten thousand yuan / ton, domestic product sales price is only 40% of the United States, the average selling price of 60,000 yuan / ton, but its profit rate of more than 50%.

In addition, the main raw material of water-soluble film is polyvinyl alcohol, China is a big raw material producer, which is extremely beneficial to the market development of the application prospect of high-tech water-soluble packaging film, and with the development and progress of society, people pay more and more attention. To maintain the environment in which we live, especially as our country is about to integrate with the international developed countries, and the environmental protection requirements for packaging are increasing. Therefore, the application prospect of water-soluble films in China must be very broad.
