Dedicated resin grade for packaging film passes appraisal
The high-viscosity nylon resin specialty compound for packaging film developed by the Research Institute of Hunan Yueyang Petrochemical General Plant recently passed expert appraisal organized by China Petrochemical Corporation (Sinopec).
The high-viscosity nylon resin for packaging film is a specialty resin for producing biaxially oriented nylon
film.
Biaxially oriented nylon
film has good burst resistance as well as advantages such as impact resistance, puncture resistance, flexibility, temperature resistance and gas barrier properties, so it is being used more and more widely as a packaging material. At present, annual output abroad reaches
more than 10,000 tonnes, while China has already reached
tonnes and continues to grow at a relatively fast pace. As a specialty resin for producing this biaxially oriented nylon
film, it has developed rapidly abroad, with Japan, Italy and other countries all having resins of dedicated grades, but it remains a blank in China, which has to spend a large amount of foreign exchange every year to import this specialty compound at high prices. To this end, the Research Institute of Hunan Yueyang Petrochemical General Plant, entrusted by Sinopec Science and Technology Development Company, from
the year, began development and research on specialty resin for biaxially oriented nylon
film. After nearly four years of effort by researchers, using a two-stage continuous polymerization process, they successfully developed a synthesis technology for high-viscosity nylon resin for biaxially oriented film on a tubular continuous polymerization unit, and produced nearly
Experts unanimously agreed that the successful development of the high-viscosity nylon resin specialty compound for packaging film fills a domestic gap, that its process technology has reached the world's advanced level, and that its product performance indicators have reached the advanced level of similar foreign products, fully meeting the requirements of domestic users.
