What is PVC wrapping film?
PVC wrapping film is a special kind of wrapping film. The commonly used width is 3cm, 5cm, 6cm, 8cm, 10cm, 12cm, 15cm, etc. PVC wrapping film is self adhesive due to electrostatic adsorption, so it will not cause secondary pollution to the packaged products. At the same time, due to the high transparency of the products, it can make the packaged products more beautiful . PVC wrapping film is a very excellent material. Characteristics of PVC wrapping film 1. The material is very soft, which can avoid damage to articles during binding. 2. The transparency is very high, which makes the goods look more neat and beautiful. 3. It has strong tensile strength and can save 50% – 80% of the packaging cost compared with other types of films. 4. Good environmental protection. It will not cause any pollution to the goods. 5. It has strong toughness and is not easy to break. Suitable for any shape of goods. Use of PVC winding film 1. Packaging goods PVC wrapping film has a good wrapping effect, and can be used to package electronic parts, building materials, rubber, low bricks, tiles, screws, wallpaper,...

What are the advantages of polyester fiber strapping belt in transportation?
Polyester fiber strapping belt is also called flexible strapping belt. It is a synthetic fiber obtained by spinning polyester polycondensated from organic dicarboxylic acid and diol. The biggest advantage of polyester fiber strapping belt is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery capacity. It is firm and durable, and can be reused for many times. The polyester fiber strapping belt has good mechanical properties. The polyester fiber strapping belt is connected with an M-shaped steel wire buckle. Under a reasonable design, it is not only firmly connected, but also will not fall off under the fastening state, greatly improving the efficiency and safety of the strapping and transportation process. 1. Strong tension: High tensile strength, able to withstand 500N-15000N tension, which can replace traditional steel strapping. 2. Good impact resistance: due to its ductility and good elastic recovery capacity, it can effectively absorb the vibration during transportation, and the goods will not become loose after shrinking or expanding, thus ensuring the goods have excellent impact resistance during long-distance transportation. 3. Safety and environmental protection: polyester fiber strapping belt is very soft and will not harm transport workers and...

How to use the portable electric strapping machine?
The portable electric strapping machine is a very portable machine, and its working efficiency is higher than that of the manual and pneumatic strapping machine. Because of its small size, light weight, convenient operation and carrying, it is widely used. Use Process 1.Put in the strapping belt. Put one end of the PP/PET strapping belt on the goods, lift the handle with the right hand and put the upper and lower strapping belts into the entrance of the electric strapping machine in parallel. 2. Tighten the strapping belt. Press the tension button above the electric strapping machine, and release the switch button after reaching the desired tension strength. 3. Fusion strapping belt. After tightening, press the welding button, and release it immediately after pressing the button. The electric strapping machine will automatically weld and cut off the excess strapping belt. 4. Release the electric strapping machine. After welding, we just need to lift the handle, the welding button will reset automatically, lift the handle to loosen the belt accordingly, and move the electric strapping machine to the right. Use Precautions 1. The width and thickness of PP strapping and PET strapping used should...

What is polyester fiber composite strapping belt?
Polyester fiber composite strapping belt is a new type of environment-friendly strapping belt that can be used to replace steel belt and PET strapping belt. It is widely used in steel industry, chemical fiber industry, aluminum ingot industry, paper industry, brick kiln industry, screw industry, tobacco industry, electronics industry, textile, machinery industry and wood industry. Polyester fiber composite strapping belt can work normally at – 40 ℃ – 130 ℃; Strong linearity and system tension; It can cushion huge impact during transportation, has excellent ductility and tightness, and is soft without damaging the surface of goods. Compared with steel belt or other strapping belts, it has the following advantages: Strong tension: high tensile strength, capable of withstanding 500-8500 kg of tension, which can replace traditional steel strapping. High impact resistance: due to its ductility and resilience after deformation, polyester fiber composite strapping belt can absorb impact energy better than steel belt, and will not become loose after the goods shrink or expand. High buckle strength: the polyester fiber composite strapping belt is characterized by connecting steel wire buckles, which is the strongest connection method, and can be tightened repeatedly and reused. Safe to use: It...

How many production processes are available for stretch film？
Stretch film is a new type of packaging material. The use of stretch film for product packaging can effectively reduce the use cost. The use of stretch film is only about 15% of the original box packaging, about 35% of the heat shrinkable film, and about 50% of the carton packaging. There are many advantages to use stretch film packaging, but do you know what the production process of stretch film is? Casting process First, pour the raw materials into a container, and then use the suction pipe to suck them into the tape casting machine. During this process, the raw materials poured into the container should not be large solids. Make sure that the raw materials are clean, and prevent the produced stretch film from being unqualified due to other particles. Next, the raw materials entering the tape casting machine are processed. The temperature here must be strictly controlled to prevent the production of unqualified stretch film, which is then drawn by cooling with a cold roll. Then, roll up the stretch film produced by the casting machine, and the stretch film roll is completed. In the process of extrusion casting and cooling shaping, there is no...
