Product description
The HN-650-1250 single and double layer coextruded winding film unit is an advanced film production equipment, which belongs to the category of plastic film production equipment along with stretch film production line, protective film production line, and casting machine. It plays an important role in the production of packaging materials.
The unit uses LLDPE as the main raw material, adopts several different grades of resin, and produces self-adhesive single-sided adhesive or double-sided adhesive stretch winding film through extruder. The film has high tensile strength, puncture resistance and impact resistance. The winding film has good recoil memory and self-adhesive, which can make the goods tightly wrapped into a whole. Prevent the fall and pollution during transportation, and the film has excellent transparency and extensibility, can make the packaging items beautiful, economical and practical. It can be widely used for containerized pallet packaging of bulk goods, and is a better alternative product for heat shrink packaging film in transportation.
◆ HN-650-1250 single and double layer coextruded winding film unit is an advanced film production equipment, mainly used for the production of high-quality composite film and plastic packaging film. The unit adopts advanced coextrusion technology, which has efficient and stable production performance and excellent product quality. This is consistent with the goal of pursuing high-quality films in the protective film production line, and also integrates the advanced technology concept of the casting machine in film forming.
The unit adopts single or double layer coextrusion process, can produce different specifications, different varieties of film products according to customer requirements. Through the use of advanced extrusion systems and control systems, high precision extrusion operations can be achieved to ensure the uniformity and stability of the film.
The main components of the unit include extruder, die head, wind ring, straightening frame, winding machine, etc. The extruder is the core component of the unit, which realizes the production of plastic film by heating, melting and extruding plastic raw materials. According to different product needs, different models and specifications of extruders can be selected to meet the production requirements of different products.This is also a common configuration method in stretch film production line and protective film production line.
The die is one of the important factors affecting the quality of the film. By adjusting the structure and parameters of the die head, the thickness, width and flatness of the film can be controlled, so as to achieve the production of different products. The unit adopts advanced die design and processing technology, which can provide high quality die and ensure the stable quality of film products.
The wind ring is a device that helps the film cool and solidify quickly. By adjusting the wind speed and temperature of the wind ring, the cooling speed and tensile degree of the film can be controlled, thereby improving the physical properties and appearance quality of the film. The wind ring of the unit uses an efficient cooling system and wind speed control device, which can achieve accurate temperature and wind speed control to ensure the cooling effect and stability of the film.
The straightening frame is used to adjust the flatness and flatness of the film. By adjusting the tension and tension distribution of the straightening frame, the deformation and ripple of the film can be eliminated, and the flatness and appearance quality of the film can be improved. The straightening frame of the unit adopts advanced tension control system and straightening mechanism, which can realize high-precision straightening operation and ensure the flatness and stability of the film.
The winding machine is the film is rolled into a drum equipment. By adjusting the tension and speed of the winding machine, the winding tension of the film and the diameter of the drum can be controlled. The winder of the unit adopts advanced tension control system and automatic coiling device, which can realize high-precision coiling operation and ensure the coiling quality and stability of the film.
As an advanced film production equipment, the HN-650-1250 single and double layer coextruded winding film unit has high efficiency, stable production performance, and excellent product quality. The collaborative operation mode of its main components is consistent with the overall process logic of thestretch film production line and protective film production line, and some core technologies also draw on the advantages of the casting machine. By adjusting the process parameters of each component, different products can be produced to meet the diverse needs of customers. This unit is widely used and can serve industries such as food, medicine, chemical, and papermaking, providing customers with high-quality packaging materials.
