On July 7, the bidirectional stretch polyethylene (BOPE) special materials and film products independently researched and developed by ZGSH Petrochemical Group Chemical Research Institute reached the world's leading level through various performance indicators and filled the domestic gap. BOPE film is widely used in rice vacuum packaging, quick-frozen food packaging, beverage transparent flexible packaging and other fields. Compared with traditional polyethylene film, it can reduce the amount of material used by 30%, and is economical and environmentally friendly.
BOPE film is made of polyethylene resin with special molecular structure design into a high-performance film product through a special bidirectional stretching process. Compared with traditional polyethylene film, BOPE film not only has better toughness, stiffness, puncture resistance and low temperature impact resistance, but also has better transparency, printing performance and higher production efficiency. Packaging with BOPE film can effectively reduce the thickness of plastic packaging and reduce the use of packaging materials by about 30%. In addition, the “BOPE+CPE” all-polyethylene packaging products made of cast polyethylene (CPE) special materials and films that also have ZGSH's independent intellectual property rights also have significant advantages of recyclability and recycling, in line with the country's development of circular economy The strategy and the "14th Five-Year Plan" require the recycling of plastic products to meet the market's demand for green packaging.
Wu Changjiang, the project leader of the "Key Technical Problem of Functional Polymer Membrane Materials" and the president of the Chemical Research Institute, a major project of ZGSH, introduced that the domestic BOPE special materials and film products introduced to the market this year are the results of the company's intensive research and development and successfully broken Foreign monopoly.
BOPE film with excellent optical properties
This BOPE product has broad application prospects in the fields of rice vacuum packaging, quick-frozen food packaging, beverage transparent flexible packaging and other fields. Taking only China's high-end rice in 2019 as an example, the annual sales volume was about 1 million tons. If all domestic BOPE products are used instead of traditional rice packaging materials, the packaging cost can be saved by about 60 million yuan, and the plastic consumption can be reduced by about 5,500 tons. The new packaging can also reduce the breakage rate and better maintain the quality of rice.
