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...

How to distinguish the quality of PVC electrical tape?
PVC electrical tape has the characteristics of waterproof, strong viscosity, high temperature resistance and excellent electrical insulation. PVC electrical tape is often used for the insulation of wire wrapping and wire ends, which involves the safety of electricity use. Therefore, it is an important choice for every power company and electrician to choose a roll of high-quality PVC electrical tape. How do we judge that the PVC electrical tape we buy is a high-quality tape? First of all, we should start from the appearance of PVC electrical tape. A good electrical tape should have uniform color, flat cross section, and no protrusion or glue overflow. If the glue overflows, it proves that the glue of this roll of electrical tape has been aged. Wrap the film wire head with this aged tape, and the connection will loosen after a short time, causing electric leakage, which is a very dangerous consequence. Secondly, we can pull off the electrical tape and feel the peeling force and adhesion of the tape surface with our hands. Generally speaking, the peeling force of the tape is moderate. If it is too light, it is difficult for us to wind the wires. If it...

What is the function of sealing tape?
The sealing tape is mainly made of BOPP biaxially oriented polypropylene film as the base material. The sealing tape has the advantages of high tensile strength, non-toxic and tasteless, environmental protection, strong viscosity, low cost, and is also very useful in industry. The sealing tape can fix the product and reduce the loss caused by product scattering. The use of sealing tape can also play a role in anti-counterfeiting and anti-theft. It can also print the company’s name, logo and the company’s activity date on the sealing tape. This can not only promote the company’s activities, but also help make the company famous. It is an indispensable packaging product for industrial production. It is also an indispensable article in life. Next, we will introduce the use of sealing tape in life. 1. Sealing tape sticking to hair: It is difficult for us to clean the hair falling on the floor or carpet. We just need to find a roll of packaging tape, cut a section, and stick it on the floor or carpet. Even the dust on the floor can be stuck off without leaving any trace. 2. Sealing tape instead of binding rope: sealing tape can not...

How to deal with the used stretch film?
As the stretch film has a good effect as a packaging material, it can be seen in packaging places in all walks of life. Stretch film is a kind of plastic packaging material. Plastic is difficult to be degraded for a long time. If it is thrown about, it is easy to pollute the environment. But what should we do with the stretch film after use? In fact, as a manufacturer, when we were initially approved by the state for production, we had taken into account the environmental pollution caused by the stretch film. In order to create more renewable resources and promote the sustainable development of resources, plastic packaging products need to be recycled and utilized again. As a recyclable plastic film, stretch film can be recycled after we use it, which can not only protect our environment, but also create secondary value for us. The demand for stretch film packaging continues to grow. At present, the world’s production capacity can reach several million tons. The treatment technology of stretch film packaging waste is very mature at present. If we recycle the stretch film, after crushing and safe treatment, a ton of plastic stretch film can bring...

How to use polyester composite packing belt and steel wire packing buckle together？
Polyester composite packing belt and steel wire buckle are used together, which is a very efficient packaging method. The connection success rate of polyester composite packing belt and steel wire packing buckle can reach more than 90%, and the operation is very easy without too much skill. Next, we will introduce the steps of using polyester composite packing belt and steel wire packing buckle together: Step 1: Fold the polyester composite packing belt outward in half, leaving a space of about 10cm at the fold. Step 2: Insert the folded polyester composite packing belt into the middle of the steel wire packing buckle. Step 3: Then align the middle gap of the folded polyester composite packing belt with one end of the steel wire packing buckle and insert it. Step 4: After plugging, pull the polyester composite packing belt backward. Step 5: Perform the same operation at the other end, and fold the polyester composite packing belt outward. Step 6: Thread the folded polyester composite packing belt into the middle of the steel wire packing buckle. Step 7: Pass the clearance of polyester composite packing belt through the steel wire packing buckle. ...

What is the difference between Pof shrink film and PVC shrink film？
POF shrink film and PVC shrink film are both popular shrink films in the packaging industry. What’s the difference between the two shrink films? 1. Different materials and production processes POF heat shrinkable film is a kind of heat shrinkable film with high transparency, high shrinkage and good heat sealing performance, which is made by extruding the inner, middle and outer layers of linear low density polyethylene (LLDPE) as the intermediate layer and co polypropylene (PP) as the inner and outer layers in special equipment. PVC heat shrinkable film is made of ethylene PVC resin mixed with more than ten kinds of auxiliary materials and then blown twice. 2. Different physical characteristics POF shrink film is thin and tough, with uniform thickness, excellent moisture resistance and soft texture The tensile strength is high, the tear resistance is high, and the shrinkage is adjustable. The PVC shrink film is thick and brittle, uneven in thickness, poor in moisture resistance, hard and brittle in texture, low in tear resistance, low in shrinkage, and poor in rubbing resistance. 3. Different cold resistance POF shrink film has excellent cold resistance. It is not hard, brittle and easy to...
