PP packing belt appearance: translucent to opaque, transparent film texture.
Flammability: flammable in flame. Slowly extinguish or continue to burn after leaving the flame. When burning, the upper end of the flame is yellow, the lower end is blue, melting and dripping.
Polypropylene drawing grade resin has been widely used in various fields because of its good plasticity, strong breaking force, bending fatigue resistance, low density, good tensile impact performance and easy to use.
Our workshop has more than ten packing belt production lines in stock to support customers to visit and inspect on site. Buy our packing belt production equipment, we will send professional technical personnel free door installation debugging, teaching operation and formula. Buy equipment, test the machine first, then deliver. Before leaving the factory, the packing belt production equipment of our factory should be debugged and tested in the workshop to ensure the normal production of the machine before delivery. Customers can be assured to buy, test machine can also watch the production site, on-site testing.
The PP strapping production line produced by Qingdao Zhongrui Plastic Machinery Co., Ltd. introduced foreign technology. After painstaking research, a new generation of one-machine double-belt PP strapping production line was developed. This production line can produce ultra-thin straps, original rice straps, and environmentally friendly packaging. Belts, the products produced have neat, uniform and clear patterns, and are lighter than grams. The extrusion host of the one-machine double-belt strapping production line is made of 38 chromium molybdenum aluminum after nitriding, and adopts a new compression ratio that meets the characteristics of PP. Screw barrel, special hard tooth surface reducer for plastic machine, high specification configuration to ensure extrusion effect. The die head of the PP strapping production line adopts a mechanical fine-tuning die head, and the strip blank is formed smoothly and stably. The stainless steel cooling water tank and the new big five-roll traction ensure the stable growth of product forming quality. The new type of coiling technology overcomes the phenomenon that the product has a large skewness and serious bending deformation at the corners after the previous equipment is coiled, and the coiling is flat. Embossing roller embossing, the pattern is clear and uniform, and the appearance of the product is beautiful and high-grade. Dosing and mixing of raw materials. Preheating and drying automatic cycle. Uniform plasticization and stable extrusion, accurate temperature control. The metering pump ensures continuous and stable products. Large traction product stretching device and insulated oven. Large-capacity stainless steel sink with automatic liquid level control. Specially designed than screw extruder. 100% of the recycled material can be used with a powerful vacuum system, which can avoid the dehumidification and drying of the raw materials. Energy consumption is 40% lower than that of raw materials. The company can provide process recipes and turnkey projects.
