PRD purchase packing belt supplier FOSHAN GUANGCUN packing belt factory
1, polypropylene (PP) as the main raw material, material: polypropylene drawing grade resin, because of its good plasticity, breaking pull. Strong strength, resistance to bending fatigue, low density, good tensile impact properties, ease of use, etc., are now widely used in various fields. 2. Applicable to all kinds of packing machines (semi-automatic, fully automatic, manual packing machine) for all walks of life. 3, strong adhesion force, large pulling force, light weight, corrosion resistance, beautiful appearance, high grade 5, bright color, yellow White ink and other colors, you can choose 6, you can according to customer requirements and samples, production and printing, printing icons, and other special packaging belt 1. Polypropylene raw materials for the production of packing is transparent granular, so PP packing belt can be classified as: Transparent PP straps Translucent PP straps Color PP straps 2. According to the proportion of polypropylene used to produce the packaging tape, PP straps can be divided into: New pure PP strapping pure material (recycled material) PP strapping Ordinary sandwich PP strap 3. According to the use of the use can be divided into automatic PP strapping; semi-automatic PP strapping; manual PP strapping; flexible PP strapping. The use of PP straps: used for carton packaging, with the use of automatic balers. PP packing color: white, red, yellow, blue, and other colors. PP packing material: Polypropylene drawing grade resin, because of its good plasticity, strong breaking tension, bending fatigue, low density, good tensile impact properties, easy to use, etc., has now been widely used in various fields. PP strapping production process: The first is the extruder temperature control is generally 250 °C ~ 280 °C. The next step is cooling. After the material is brought out of the head, the temperature is very high, and it is necessary to immediately enter the water to cool, because the isotactic polypropylene easily generates a twin structure in the case of quenching, and the twin crystal structure is loose. Easy to stretch orientation, to obtain high quality products. This is followed by stretching. The purpose of stretching is to increase the longitudinal strength of the strap and reduce the elongation. Stretching must be carried out in boiling water, and one stretch is generally used. After embossing, the stretched straps are pressed onto the pattern after two patterned press rollers. Their effect is to increase the friction in use, not to slip, and to look beautiful from the outside. Pull-out force parameter and elongation of PP strapping belt: 1.12mm wide and 0.6mm thick pure PP strapping tape with breaking force> 1000N Elongation: <20% 2. 13.5mm wide and 0.6mm-0.8mm thick Specification of pure material PP strapping with its breaking tension: 1000N-1500N Elongation: <20% 3, 15.5mm width 0.6mm-0.8mm thick gauge and pure material PP strapping with its breaking tension: 1500N -2000N Elongation :<20% 4,19mm width, 0.6mm-0.8mm thick gauge and pure material PP strapping tension: 2000N -3000N Elongation: <20% PP strapping production process PET strapping production process: plastic pellets Melting --- pressure belt ---- molding ---- cooling --- winding --- packaging --- storage. The PET strapping tape is made of polypropylene, which has been heated, melted, stretched, and cooled to produce a net-like structure of packaging materials. The basic parameters affecting the quality of the strapping tapes are tension, length, bending, and elongation. In the case of the same pulling force and other parameters, the longer the length, the lower the cost. PET packing belt has introduced four world advanced packing belt production lines and adopts processing technology to produce high-strength, high-quality, environment-friendly 3000 meters of new packing materials. The unit cost per meter is far lower than the domestic return tape and similar imported belts. unit price. The packaging belt is made of polypropylene, which has been heated, melted, stretched and cooled to produce a net-like packaging material. The basic parameters affecting the quality of the packaging tape are tension, length, bending and elongation. In the case of the same pulling force and other parameters, the longer the length, the lower the cost. Hangzhou Yongchuang has introduced four world-leading packing belt production lines and adopts processing technology to produce high-strength, high-quality, environment-friendly 1,000 meters of new material packing belts. The unit cost per package is much lower than the domestic return belts and the like. With the unit price of imported belts, the cost is reduced by 120%.
