Issue 48/2014 - Industrialization of POF special resin for Tianjin Petrochemical Small Ethylene Plant

A few days ago, Tianjin Petrochemical Small Ethylene Plant successfully completed the industrial production of POF special resin, breaking the monopoly position
of imported products in the domestic market.

POF film is an environmentally friendly multi-layer co-extruded polyolefin heat shrinkable film, which is a heat shrinkable film
made by using linear low-density polyethylene as the middle layer and co-polypropylene as the inner and outer layers, and extruding the inner, middle and outer layers together by a special process.
Because of its good transparency, the product is widely used in the packaging field of beverages, convenience foods, daily chemical products, audio and video products, books and periodicals, medicine, electronic components and other special-shaped products, and is currently widely promoted and used internationally and recognized by the European and American markets as environmentally friendly heat shrinkable packaging materials
.

Tianjin Petrochemical found that the market capacity of POF membrane is large, about 180,000 tons / year
.
Among them, linear low-density polyethylene as the middle layer, the dosage is about 130,000 tons / year, and the annual growth rate
is 20%~30%.
Due to technical limitations, the raw materials of high-carbon linear low-density polyethylene (LLDPE) resin, which are the intermediate layer of this product, are all dependent on imports
.
Tianjin Petrochemical successfully developed an environmentally friendly polyolefin heat shrinkable film DFDA-6010 through the selection of molecular design, catalyst system and auxiliary system, and successfully developed an environmentally friendly polyolefin heat shrinkable film DFDA-6010 through the adjustment and optimization of polymerization process, and realized industrial continuous production
