I saw the researchers put white plastic in ordinary cold water, more than ten seconds later, the plastic completely dissolved in water. Then, put a kind of plastic in the cup of hot water, just a few seconds, plastic completely melt. This is the morning of June 20, a reporter in lanzhou high-tech zone a high-tech enterprise witnessed a magical situation.

Called "full biodegradable environmental protection packaging materials polyvinyl alcohol (PVA) membrane" project, is developed by lanzhou transit key environmental protection packaging materials technology co., LTD., after many years of research and development, its core technology won two national invention patents, its production process and production equipment, the department of science and technology novelty search results for "no" at home and abroad. Patent Zhang Jiancun introduction, we have developed two kinds of cold water soluble film and hot water soluble film, a total of five varieties of PVA film, compared with other plastics, its biggest characteristics is a fully biodegradable and nontoxic, by two kinds of bacteria to eat off plastic chain, thin film is a new generation of environment friendly materials, can be widely used in clothing Embroidery, hospital, packaging and other industries. Most importantly, by the authoritative department detection show that the "full biodegradable environmental protection packaging materials polyvinyl alcohol (PVA) membrane" melted water, soil, water does not cause any pollution hazard, and the effect on soil and osteoporosis.

At present, China's demand for polyvinyl alcohol film is increasing at an annual rate of 8% to 10%, mainly relying on imports, from Japan import a ton of about 200,000 yuan. Due to advanced technology, lanzhou zhongtianjian has an average cost of just over 30,000 yuan to produce a ton, and the market price is between 60,000 and 80,000 yuan. Therefore, the market potential is huge. However, due to the lack of funds, the project in lanzhou can't start the production, the east, some enterprises of fujian after we received the information of lanzhou has a good project, inviting patent Zhang Jiancun to them factory production, requires the order even more. Zhang jian on principal think oneself is lanzhou people, expect the project to blossom in lanzhou, but with the reporter's persuasion, he has changed his mind, factory production, investment to where you can go abroad is better.
