In 2010, Changzhou Hefeng Packaging Materials Co., Ltd. introduced a 3500 type large-scale blown film machine for the production of outer packaging film for sponge materials and large products, in the process of continuously promoting production capacity improvement and technological upgrading. This equipment investment not only expands the wide specification capability of membrane materials, but also further enhances the supporting manufacturing capability of the enterprise in the field of foam packaging materials.
It is reported that this model of blown film machine has high production stability and film thickness control accuracy, supports co extrusion processing of various raw materials, and is suitable for producing packaging films with large format, high toughness, and strong dust and moisture resistance, meeting the packaging needs of lightweight and large materials such as sponges, foam, and home parts.
Industry observers believe that with the increasing demand for diversified packaging specifications and functional requirements from customers, wide blown film equipment is becoming an important tool for packaging material manufacturing companies to expand their business capabilities. The introduction of 3500 type equipment by Hefeng this time is another key action to improve its product system and enhance production flexibility.
The enterprise side stated that the equipment has been officially put into operation and will cooperate with multiple existing film and bag making production lines to continuously optimize product delivery cycles and application performance, providing more process support for subsequent material function expansion.
