Solve the traditional packaging film can not have both high temperature and high strength problems

<

Recently, the Ningxia Science and Technology Achievement Management Center organized relevant experts to carry out scientific and technological achievements appraisal of the “New High-Strength, High-Temperature-resistant Polyethylene Packaging Intima” project completed by Ningxia Runlong Plastic Chemicals Co., Ltd.

The project has solved the problems that the traditional packaging intima cannot have both high temperature resistance and high strength by improving the polyethylene packaging film production formula and blow molding process parameters. The product quality is superior to the GB/T4456-2008 technical standard and meets the requirements for hazardous chemicals packaging standards. Among them, high temperature resistance 110°C, longitudinal tensile strength ≥ 35MPa, transverse tensile strength ≥ 40MPa, longitudinal elongation at break ≥ 656%, transverse rupture elongation ≥ 64%, film impact test (90g) does not rupture, sample impact 10 The sheet is crack-free.

At present, enterprises have formed 40 million sets of polyethylene intima production capacity. The products are sold to large enterprises such as metallurgy, chemical engineering and building materials in our district and surrounding provinces and districts. These products meet the high temperature resistance, corrosion resistance, and high strength properties of polyethylene inner bag products in the production, packaging, and transportation of these industries. The request. Since the company began mass production in June 2012, it has realized a sales income of 20 million yuan and a profit of 2.3 million yuan, which has achieved remarkable economic benefits and a good application prospect. The implementation of the project has played a positive role in promoting the upgrading of the packaging materials industry in our district and stimulating the local economic development.
