In the past, the resin packaging bag production equipment used by domestic petrochemical enterprises was imported from abroad, and the price was extremely expensive. The blown film packaging unit developed by Dalian Rubber & Plastics Co., Ltd. not only completely replaces imported equipment, but also costs one-third of the imported equipment. Its technical performance has reached the international advanced level, and it is the first blow-molding heavy packaging film unit with independent intellectual property rights in China.
The first domestic blow molding heavy packaging film unit was successfully tested in the recent load linkage test. The successful trial run of this blow-molding heavy-duty film unit developed by Sinopec Maoming Petrochemical Co., Ltd. marks the end of the long-term dependence on imports of resin re-packaging film used in China's petrochemical industry.
