Unique petrochemical "polyethylene" sword refers to the field of high-end packaging

[China Packaging Network News] On August 9, Dushanzi Petrochemical Company's metallocene polyethylene product HPR1018HA's heavy packaging film processing trials succeeded at a downstream company and the product was approved by downstream users. Independent Petrochemical made an important breakthrough in optimizing product structure.

Since the beginning of this year, Sinopec Corp. has passed market research and judgment, and began to carry out product upgrades and improvement work on the huge demand for heavy packaging films used to package plastic raw materials and chemical fertilizers.

Although most of the domestic use of PP woven bags and paper bags as heavy bags, but with high performance and high packaging efficiency of heavy-duty film is receiving more and more attention, especially with the success of several petrochemical projects in the country The start of the process will make the prospects for heavy-duty packaging films very promising in China.

HPR1018HA is a metallocene polyethylene product produced by the UNIPOL gas phase polyethylene process. The product has the characteristics of narrow molecular weight distribution, high mechanical strength, and strong puncture resistance.

Downstream users often use it to produce various types of three-layer coextruded inner and outer layers of heavy-duty packaging films, inner layers of flexible packaging films, and inner and outer layers of agricultural films. The market demand is huge.

According to statistics, the current demand for HPR1018HA is more than 200,000 tons per year, and the price is higher than that of ordinary LLDPE. This trial is a field test of Dushanzi Petrochemical's HPR1018HA on the downstream first re-packaging membrane manufacturer. The commissioner formulated the plan and participated in trial production of the product.

After technical cooperation between the Institute of Petrochemical Corporation, Northwest Chemicals sales personnel and downstream users, the Dushanzi HPR1018HA was determined to have the ratio and processing conditions in the heavy-duty film. In order to test the extreme processing performance of Dushanzi HPR1018HA, both testers decided to increase the host extrusion volume to the production limit. After a slow parameter adjustment, the processing parameters and bubble stability.

After testing by the downstream user testing center, Dushanzi HPR1018HA and the benchmarking product ExxonMobil1018HA are all at the same level, which can meet the downstream users' demand for raw materials for heavy packaging films.

In the later period, the Petrochemical Research Institute will continue to conduct in-depth testing of samples to ensure that HPR1018HA will be further promoted in the downstream. The success of the HPR1018HA field test has also made headway for the promotion of Dushanzi Petrochemical Company's HPR series metallocene polyethylene.
