PP packaging ban Strapping with appearance: semi-transparent to bright, bright texture film. Incineration: Flammable in flames. After escaping the flame, slowly calm down or continue to burn. When the PP strap is burned, the top of the flame is yellow and the bottom is blue; there is a melting and dripping appearance. White scent can be smelled.
Since its establishment, the company has been committed to high-end research and development of the packaging industry for 25 years. It has always adhered to the operating philosophy of "high-quality industrialization, professional service," and cooperated with many world-class packaging companies to introduce leading-edge equipment and technologies. A variety of specifications of PP Plastic Strapping, PET plastic steel belt, automatic, semi-automatic, hand packer and spare parts.
25 years of packaging materials production experience, we created a "Yongning packaging" this brand! We produce high-quality packaging materials that meet environmental requirements. "Quality first, customer first", we follow this one operation theme, continuous innovation, rapid development.
Pp Strapping production technology:
The first is that the temperature control of the extruder is usually in the range of 250°C to 280°C. The next step is cooling, after the material is brought out of the head, the temperature is very high, and it should be immediately cooled in water. Since the isotactic polypropylene simply generates a twin structure in the case of quenching, the twin crystal structure is loose. Simply stretch the orientation to obtain high quality products. This is followed by stretching. The purpose of the stretching is to increase the longitudinal strength of the strap and reduce the elongation. Stretching must be done in boiling water, usually using one stretch. The last is embossing. After the stretched PP Strapping belt is pressed by two striped pressure rollers, it is pressed with a stripe. The PP strapping function is to increase the conflict in use, not to slip, and to look beautiful from the outside.
The PP strapping belt is made of polypropylene, which has been heated, melted, stretched, and cooled to produce packaging materials with net-like structure. The basic parameters that affect the quality of the strapping are the tension, length, bending, and elongation. In the case of the same pulling force and other parameters, the PP strapping tape has a longer length and lower cost. Introduced four of the world's leading packaging belt production lines, using processing technology, production of high-strength, high-quality, environmentally-friendly new material packaging belt 3000 meters, the price per meter of packaged price quoted far lower than the domestic return tape and similar imports With the unit price of the belt, the cost decreased by 120%.
