The process is shown in the figure below. Because the single -layer stream cannot make a single -sided sticky, the application field is limited.In the early stage, LLDPE stretching membranes are mostly blowing membrane, from single layer to two and three layers; mainly the production of LLDPE stretching membranes based on the flow method.Today, I want to share with you to distinguish whether the tape in daily life can tolerate higher temperatures.

You can also take out a small cut of the tape for buing and check. . It can also allow the tape to be in a high temperature environment of about 260 ° C to see if there is a gel. The three points mentioned above are the way to distinguish whether the tape can resist high temperature. The first is its appearance, check whether its surface is smooth. Please visit the film information .

It is non -toxic and pollution, which is harmless to people's health! PE stretching film has high strength, abrasion resistance, corrosion resistance, rain resistance, beautiful color, convenient use and other information. It uses Wholesale Bopp Stretch Film PE plastic materials with synthetic fiber with telescopic performance.

The wound film is divided into: PE entangled membrane, stretching membrane, machine -entangled film, handwing film, color -colored winding film, black wound film, small film [product use]: suitable for daily hand packaging and machine packaging packaging and machine packaging.

Items are widely used for various products such as bundling packaging.The company's entangled film is made of polyethylene as the raw material. Packaging, bundle, binding, gardening, shopping mall supermarkets, and daily life are also used for cardboard, carton, color boxes, wooden support packaging and reinforcement, printing and other industries

Keep the tape roller, the roller is flexible, and the tension is moderate. Find the damage of the tape. The storage time should be tued over once a quarter; Do not allow the tape to make a c Japanese or snake. Do not fold the rubber paper and place it in rolls.

Find the cause and repair it in time to avoid the occurrence of adverse consequences. Keeping the cleanliness of the surrounding gum's environment is the basic condition for good use of rubber paper. Select the type of tape according to the needs of the tape.Foreign material will affect the bias, different tension, and even break.

The tape should be stored in the paper clear packaging tape suppliers warehouse to avoid sun exposure and rain; It is found that the room temperature is between -15 ° C ~ 40 ° C outside of 1M; This is to ensure that the tape surface is dry and clean. Also, when buying tape, do not blindly pursue cheap prices, but ignore the quality of the tape, which will cause upside down.

First of all, when using tape, you must not use sharp metal tools to rub on the surface of the tape. Do not pour acid and alkali on the surface of the tape, organic chemical solvents. And in order to ensure that the tape can be used, it often needs to be regularly used to wipe the surface of the tape with a wet cloth.Generally speaking, before using tape, you first understand some knowledge points about tape.

It is actually helpful for us to use tape.The following editors will take you to understand that when storing the stretching membrane, there are usually any problems worth noting. When storing the stretching film, the form of storage must be paid attention to, such as the folding situation cannot be folded.

Let ’s take a look together!The three points described above are issues that must be paid attention to in the process of storing the stretching membrane.When there are a large number of stretching membranes that are not sold, it is necessary to do it. 

The structure of the polymer will change, and such an extreme stretching rate will be changed. Therefore Non -stick layer adds an appropriate medium -density linear polyethylene (LMDPE). These stretch membranes are full of calcium carbonate and other minerals. Generally, the stretch membrane is generally not tensile. Because the wide molecular measuring distribution makes it worse.

Material density also affects the performance of the wound film. Adding LMDPE can reduce the non -adhesive friction coefficient and avoid the packaging tray and the tray sticking together. Therefore, the performance of the stretch membrane is enhanced, and the longitudinal stretching can open the pores that given the product's breathable performance.

If the PIB or the mother material is used as the adhesive layer, it will also affect the movement of the PIB and reduce the final viscosity of the wound film. The China custom Hand Stretch Film PP stretching rate can reach 8: 1. The stretching rate is limited by the polymer to use a cluster or mix with some luminous metal PE.1. The temperature of the cooling roller increases, the yield strength increases, but other performance decreases, so the temperature of the general cooling I roller is controlled at 20 ° C ~ 30 ° C.

As the density increases, the orientation is increased, the flatness is good, the longitudinal extension rate is increased, and the yield strength is increased, but this makes the horizontal tear strength, puncture strength and light transmission rate of the wound film. The tension is generally not greater than 10kg, which is too large to survive in the membrane roll, which reduces the performance of the elongation rate, which is likely to cause the broken membrane phenomenon
