How does express bag film blowing machine improve the toughness of film?
Publish Time: 2025-03-20
When express bag film blowing machine produces two-layer co-extruded tube film or monolithic film, it is crucial to improve the toughness of film.1. Optimize production processPrecisely control temperature: The heating system of the film blowing machine needs to be carefully adjusted to the best state. If the temperature is too high, the film is easy to deform and become brittle; if the temperature is too low, the film thickness will be uneven and even break. The toughness of the film can be significantly improved by carefully controlling the extrusion, cooling and stretching links.Optimize the blowing ratio and traction ratio: Moderate blowing can ensure uniform expansion of the film, while precise traction gives it a stable size and shape. The optimization of the blowing ratio and traction ratio helps to improve the toughness and overall performance of the film.2. Choose suitable raw materialsSelect high-quality resins: The purity and stability of the raw materials directly affect the transparency, strength and durability of the film. Choosing raw materials suitable for your own production process, such as adding toughening agents, can significantly improve the toughness of the film.Use of additives: Using appropriate amounts of toughening agents, antioxidants, anti-ultraviolet agents and other additives can further improve the toughness, weather resistance and service life of the film.3. Adjust machine settingsAdjust the extrusion speed: The speed of extrusion directly affects the extrusion quality and toughness of the film. By adjusting the extrusion speed, the extrusion process of the film can be optimized, thereby improving its toughness.Adjust the cooling temperature: The cooling temperature has an important influence on the crystallinity and toughness of the film. By adjusting the cooling temperature, the crystallization process of the film can be optimized, thereby improving its toughness.4. Increase processing technologyUse composite technology: By compounding films of different materials, a multi-layer composite film can be formed, thereby improving the toughness and other properties of the film.Coating technology: Applying a special coating on the surface of the film can enhance the toughness, wear resistance and weather resistance of the film.5. Strengthen quality controlEstablish a complete quality control system: Strictly test and control the procurement of raw materials, production process, and factory products. Through regular testing and analysis of performance indicators such as the toughness of the film, timely discover and solve problems.Regular maintenance of equipment: Clean screws, precise die heads, stable cooling systems and other equipment conditions are the key to ensuring stable film quality. Regular maintenance and care of the film blowing machine can extend the service life of the equipment while ensuring the production quality of the film.In summary, by optimizing the production process, selecting suitable raw materials, adjusting machine settings, increasing processing technology and strengthening quality control, the express bag film blowing machine can significantly improve the toughness of the film. This will help produce higher quality express bags and other film products to meet the diverse needs of the market.
