Production and development of various special shrink films and wrapping films to meet the different needs of customers
In the production process, accurate control of key process parameters such as temperature, pressure, speed, etc. is the core link to ensure the stable performance of low-temperature shrink film (such as JT04 low-temperature shrink film). Our company, as a leader in the industry, is well aware of the importance of this and has formed a set of scientific, sophisticated and efficient control systems in practice to ensure that each batch of low-temperature shrink film can achieve optimal performance.
1. Technical details: Accurate control of process parameters
For low-temperature shrink film, temperature is the key factor affecting its shrinkage performance, sealing and appearance quality. JT04 low-temperature shrink film uses special formulas and raw materials to achieve excellent shrinkage effect at lower temperatures. To achieve this goal, we use an advanced temperature control system, including intelligent thermostats and precision temperature sensors for heating elements. High-precision temperature sensors are installed at various key nodes of the production line, such as extruders, heat setting areas, cooling areas, etc., to monitor and feedback temperature data to the control system in real time. The system automatically adjusts the heating power according to the preset process curve to ensure that the temperature fluctuation range is extremely small, so as to ensure that the JT04 low-temperature shrink film is processed within the optimal temperature range, which not only ensures the shrinkage performance, but also avoids the aging or deformation of the film material caused by overheating.
Pressure control is also very important, which directly affects the uniformity of the extrusion thickness, tensile strength and flatness of the film after shrinkage. We use a closed-loop pressure control system to accurately control the pressure distribution of the film material during the extrusion and stretching process by adjusting the extruder screw speed, die gap and the pressure setting of the subsequent traction and stretching equipment. Especially in the extrusion stage, through precise screw speed control combined with advanced pressure sensor monitoring, the pressure of the molten material at the die outlet is ensured to be stable, so as to obtain a film material with uniform thickness and excellent mechanical properties.
Speed control covers multiple aspects such as extrusion speed, stretching speed and winding speed, which together determine the production efficiency and final performance of the film material. We use advanced PLC (programmable logic controller) and servo motor technology to achieve precise control of the speed of the entire chain from extrusion to winding. Through the preset program, PLC can dynamically adjust the speed of each section according to the actual production situation, ensuring that the film material maintains the best speed matching during extrusion, stretching, shaping, cooling and winding, avoiding the problem of unstable film performance caused by speed fluctuations.
2. Quality control system: comprehensive control from source to terminal
In order to ensure the stable performance of JT04 low-temperature shrink film, we have established a full range of quality control systems from raw material procurement to finished product delivery. First of all, we strictly screen suppliers and only use imported advanced raw materials. These raw materials have undergone strict performance testing and batch tracking to ensure their stable and reliable quality. In the production process, each process has a quality inspection point, including but not limited to extrusion thickness monitoring, tensile strength testing, shrinkage testing, sealing testing, etc. All tests are carried out in accordance with international certification standards such as ISO, BRC, SGS, and FDA. In addition, we have also implemented BRC certification to ensure that each step of production meets the highest standards of food safety and quality management, making each batch of products traceable and more stable.
3. Company advantages: technical strength and production capacity guarantee
As a leading company in the industry, we have a strong technical R&D team and advanced production equipment, which is the basis for us to achieve precise control of process parameters and ensure stable product performance. We continue to invest in research and development, optimize formulas and processes to adapt to the market's growing and diversified demand for low-temperature shrink film. At the same time, our production capacity is sufficient, and we have a high degree of control over the price, quality and stable supply of raw materials. This not only lays the foundation for our continued production of high-quality products, but also ensures that we can flexibly respond to changes in market demand and provide customers with stable and reliable product supply.
Through fine technical control, a comprehensive quality control system and strong company advantages, we ensure the precise control of key process parameters such as temperature, pressure, and speed during the production process of JT04 low-temperature shrink film, thereby achieving long-term stability of product performance. Whether it is from raw material selection, production process control, or final product testing and certification, we strive to do our best to provide customers with high-quality and high-performance low-temperature shrink film solutions to help customers stand out in the fierce market competition.
