How to Identify The Quality of Colored Tape?

For colored tape, it is used for marking and masking purposes, generally beige and khaki are more common. Many people think that colored tape is the color of the film, but the color is actually the color of the glue. Pinch the glue tightly and pull it apart quickly, you can tear off the glue on one side, and you can see the purity and transparency of the original film. It is important to look at the thickness of the glue. If no glue is pulled apart or pulled apart in dots, there are a lot of impurities in the glue, and the glue has no cohesion. Second, too much water has evaporated. At this time, the initial adhesion of the tape has dropped a lot, and the feel can be distinguished. Attach the yellow tape to the object, the better the concealment, the thicker the glue, the better the quality. Another important condition for distinguishing between good and bad tapes is not to feel the viscosity with your hands, because the initial adhesion of the doped tape is very high when it is not volatile, so stick the tape to the object and then quickly pull it away to see the retention. Repeatedly pasted several times, and then touched with hands, the sense of elasticity decreased significantly. Doped tapes are often dissolved in gasoline and acid when formulating the glue, so the smell is very strong. Regular large enterprises use toluene to dissolve, and are volatilized by the fan during the coating process. Having said all this, you may ask, is there a difference in the quality of the tape used? In fact, the purpose of using tape is not to stick the problem, but to stick firmly instead of separating. Most of today's doped tapes will collapse after a period of time (between 20 minutes and 1 hour) and cannot be reapplied, especially in the cooler and windie

What Are The Main Functions Of Stretch Film?

The main function of stretch film is to protect the product stacked on the pallet and prevent the goods from collapsing during the transfer or storage of the pallet as a unit. Usually at the time of receipt, the item appears to be protected with a stretch film, and when shipped in bulk, the stretch film is removed. There are two main ways of winding, one is machine winding and the other is manual winding. Both methods have their own advantages and disadvantages, which need to be selected according to the actual situation. If it is a machine coating, the action is set in advance and is more standardized. However, the packaging of offline products in non-production factories usually requires the cooperation of forklifts and forklift drivers (some use artificial cattle, and use slopes to push up), mainly placing stacked products on film wrapping machines using forklifts. Manual dressing is not easy to standardize because there are many operators, especially the strength of the dressing. For warehouses, stretch film is a non-reusable material. When receiving, please use stretch film for protection. When shipping in bulk, you will need to remove the stretch film from the cargo. In addition, if the roll is shipped, it also needs to be protected with a stretch film.

Repair the scratches of the blanket Regarding the repair of blanket dents, it was introduced as early as 2003 in the "Printing Technology" magazine, and two methods of blanket reducing agent and double-sided tape paper can be used. The above two methods will affect the quality of goods to varying degrees. Then came a good way to replace them with Scotch tape. In practice, the same is to first remove the rolled blanket, mark it, and then use scissors to cut a small piece of scotch tape slightly larger than the rolling mark and stick it directly at the mark. Because the transparent tape is very thin, the thickness is only about four wires. If one layer is not enough, you can add another layer or two layers, but you should cut small points in order so that there are no hard openings on the edges, and then install the blanket. . The advantage of choosing this method is that the size and shape of the transparent tape are determined by the rolling marks, and it will be s

The Thicker the Wrapping Film, the Better the Quality?

Stretch film is widely used in the packaging of food, medicine, and sterilized tableware in our daily life. According to the difference in packaging methods, its application fields will also be different. As a packaging material, stretch film can be transported and used better. It not only has the actual effect of wear-resistant, dust-proof and anti-theft, but also avoids loosening. Therefore, the thickness of the product is very important. Its thickness is mainly used to ensure its safety when it is packaged. Does that mean that the thicker the wrapping film, the better? 1. If the thickness of the wrapping film is relatively large, it is not easy to stretch, especially the hand film, which will reduce the work efficiency. 2. The thicker the film, the lower the viscosity. The viscosity of the film is its own property. In production and processing, excessively thick films produced by adding plasticizers such as DOV have different requirements in the production process, and the production and processing formulations will also change, thus reducing the self-adhesion and overall quality of the film.

Is It Safe to Use Scotch Tape to Patch Tangled Wires?

Scotch tape is used very frequently in life, such as: sealing and packaging, pasting items, bundling items, etc. The editor found a phenomenon that many people use scotch tape instead of electrical tape to wrap and repair damaged wires. So, does scotch tape have an insulating effect? Is it safe to use scotch tape to patch tangled wires? Using scotch tape to repair broken wires is a very dangerous thing. Scotch tape is not insulating. On the contrary, the adhesive on scotch tape has a conductive effect, which poses a great safety hazard. There may be a short circuit in the line, causing a fire, burning the line and equipment, and in severe cases, it may endanger human life and the consequences are unimaginable, so it is not advisable to use transparent tape instead of electrical tape. If the line is damaged, in the process of self-repair, it is recommended to use insulating electrical tape, which has good insulation, voltage resistance, flame resistance, weather resistance and other characteristics to prevent the wires from being exposed to achieve insulation. Suitable for wire connection, electrical insulation protection, etc. In the whole process of electricity consumption, although we have noticed that the size of the cross-section of the raw material of the power plug has an impact on the safety application of electrical equipment, we usually attach great importance to the insufficient application of insulating tape to the connector. The laying of switching power supply routes is becoming more and more complicated, including under wooden floors, walls, baffles, and wet ground or water. If the insulating tape is improperly operated, electricity will be generated, which will seriously endanger life safety. Therefore, we need to properly apply insulating tape, and the power plug connector is divided into "+" wiring method, "-" wiring method, and "T" wiring method. The connection head should be tightly wrapped, smoot

How to Test the Breathability of Stretch Film?

How to test the air permeability of stretch film? What is the test method? The air permeability of the stretched film is mainly expressed by the gas permeability and the gas permeability coefficient. The gas permeation rate refers to the volume of gas permeating the unit area of the tested film in unit time under the action of constant temperature and unit pressure difference when permeating stably; During stable permeation, the gas volume per unit thickness and unit area of the detected film per unit time is permeated. The air permeability test of the stretched film is carried out on a special instrument. The method is to separate the high pressure chamber and the low pressure chamber in the instrument with the film to be tested and seal it well. There is a test gas of about 105Pa in the high-pressure chamber, and the volume of the low-pressure chamber is known. At the beginning of the test, the air in the low-pressure chamber is pumped out with a vacuum pump, and the pressure is close to zero; The following points should be paid attention to when doing the air permeability test of thin stretch film: 1. The temperature should be strictly controlled during the test. 2. It takes a long time for degassing and ventilation during the stretch film test. The detection of the pressure in the low pressure chamber should be recorded after the stable penetration is achieved. 3. The test inspection process is carried out under the pressure difference between the two high and low pressure chambers. Therefore, in order to ensure the accuracy of the test data, we must pay attention to the tightness of each system in the working instrument.

Talking About the Stickiness of Stretch Wrapping Film

The stickiness of the stretch wrapping film is really important. Good stickiness makes the packaging film layers outside the goods stick together to make the goods firm. There are two main ways to obtain stickiness: one is to add PIB or PIB to the polymer. Its masterbatch; the other is blending VLDPE. PIB is a translucent viscous liquid. Direct addition requires special equipment or equipment modification. Generally, PIB masterbatch is used. There is a process for PIB to move out, which usually takes three days. In addition, it is also affected by temperature. When the temperature is high, the viscosity is strong; when the temperature is low, it is not too sticky, and the viscosity is greatly reduced after stretching. Therefore, the finished film should be stored within a certain temperature range (recommended storage temperature is 15 ℃ ~ 25 ℃). Blending VLDPE, the viscosity is slightly worse, but there is no special requirement for the equipment, the viscosity is relatively stable, not controlled by time, but also affected by temperature, when the temperature is higher than 30 ℃, it is relatively viscous, When the temperature is lower than 15°C, the viscosity is slightly poor, and the desired viscosity can be achieved by adjusting the amount of LLDPE in the adhesive layer. This method is mostly used in three-layer co-extrusion.

What Should You Pay Attention to when Choosing Tape Products?

First, smell it. Qualified tapes produced by regular manufacturers have no odor. If you find a sour smell when you buy tape, don't buy it. Because the holding power of this kind of tape is very poor, especially in a low temperature environment, the tape is easy to crack, and it will soon lose its adhesiveness. This kind of tape must be an inferior product. Second, look at the brightness of the film and touch the thickness of the film. Generally speaking, the color of inferior tape products will be much darker than that of qualified tapes, and if you touch them by hand, generally inferior tapes will be harder, and because the film is thicker, the actual number of meters will definitely be reduced. The films of good tapes are relatively soft and have good tensile properties. Therefore, the brightness and thickness of the tape film are two very important indicators, which must be observed carefully. Third, look at the color of the tape. Under normal circumstances, the whiter the color of the transparent tape and the less impurities in the tape, the normal adhesiveness can be ensured. The tape products below 100 meters have a certain transparency and the paper tube can be seen. The inferior tape is generally yellowish, and the surface is also distributed with irregular white spots. If you press it with your hand, there will be imprints of impurities or glue that cannot be wiped away. There is no doubt that the production process of inferior tape must be very rough, so the color of the tape will definitely be yellowish and there are impurities on the surface.

Where Are the Details of How the Stretch Film Protects the Goods?

Today, stretch film has been widely used in China's industrial production. Stretch film is an important material for protecting goods. It is no exaggeration to say that if the stretch film does not have a reliable protective effect on the packaged goods, then it will lose its use value as a packaging material, and it will fail in material selection. The protective function of stretch film on cargo is varied. Different commodities and different packaging methods have different requirements for the protection function of stretch film. Described here are just some of the main features to consider in general. So what are the details that reflect the good protection of the goods by the stretch film? The specific contents are as follows: 1. Reliable mechanical maintenance effect Reliable mechanical maintenance effects include avoiding cargo damage and contamination caused by leakage of goods in the package or foreign objects entering the package. The functional indicators that directly reflect the mechanical maintenance function of the stretch film are mainly the mechanical strength of the stretch film, such as tensile strength, tear strength, drop impact strength (drop impact), puncture resistance, etc. The larger the strength value, the better the curing effect. 2. Adhesion strength Good bond strength is also a necessary condition for the stretch film to reliably maintain goods. If the adhesive strength is insufficient, the gap will become the fatal defect of the stretch film, and the stretch film will lose its maintenance effect on the goods due to the damaged packaging. Ordinary biaxially oriented polypropylene film has good mechanical strength, but due to its poor adhesion function, biaxially oriented polypropylene monolayer film is generally not used for bag making. When bag making is required, a composite stretched film based on a biaxially oriented polypropylene film containing a heat-sealing layer (Xing
