adhesive tape

Adhesive tape is composed of two parts: substrate and adhesive, which connect two or more disjoint objects together by bonding. Its surface is coated with a layer of adhesive. Earlier adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; in modern times, various polymers are widely used. Adhesives can stick to things because their own molecules form bonds with the molecules of the object to be connected, and this bond can firmly bind the molecules together. The composition of the adhesive, according to different brands, different types, there are various polymers.

The tape can be used for packaging or temporary fixing of objects. It can be easily torn without any tools. There is no glue residue on the adhered surface after tearing off. It is a single-sided tape with embossed PVC as the base material, which is easy to tear without knife and leaves no glue residue. The new product S8855B has been developed. Functionally, it can partially replace the existing waterproof cloth-based single-sided tape S9522R or 4701, and the price is more competitive. The tape has been tested in the Beijing East Road store. The color is earth brown in the early stage, and it can be cut and produced according to customer specifications.

seal tape

Also known as bopp tape, packaging tape, etc., it is based on BOPP biaxially oriented polypropylene film, and is uniformly coated with pressure-sensitive adhesive emulsion after heating to form an adhesive layer ranging from 8 μm to 28 μm. It is an indispensable product in the life of light industrial enterprises, companies and individuals. The country does not have a perfect standard for the tape industry. There is only one industry standard "QB/T2422-1998 BOPP Pressure Sensitive Adhesive Tape for Box Sealing" to put BOPP original film. After high-voltage corona treatment, the surface of one side is rough. After applying glue on it, the mother roll is formed first, and then it is cut into small rolls of different specifications through a slitting machine, which is the tape we use every day. Pressure sensitive adhesive emulsion, the main component is butyl ester. High-quality and high-performance tapes perform well even in harsh climates, suitable for sealing goods in warehouses, shipping containers, and preventing cargo theft, illegal opening, etc. Available in up to 6 colors and different sizes. Neutral and personalised sealing tape.

Scotch tape

The transparent tape is based on the original BOPP film, after high-voltage corona, the surface is roughened, then coated with glue, and then divided into small rolls by slitting, which is the tape we use every day. On May 30, 1928, applications were made in the United Kingdom and the United States, and Drew developed and produced it.

Dip a sufficient amount of 95% alcohol with a soft cloth or the like, and then gently wipe the sticker. But sometimes it is found that alcohol is not very effective for some stickers. This is to use a soft cloth dipped in a little gasoline to wipe the sticker. At this time, it should be noted that because gasoline has a "dissolving" effect on certain plastics or paints, So be careful to use it: either rub it in an unimportant place first, and use it if there is no problem; but be careful not to use too much gasoline, and keep the time as short as possible. Generally speaking, wiping with gasoline on the surface of the car body for a short time has no obvious effect on the paint film on the surface of the car body. In this way, the sticker can be easily removed.

sealing tape

In daily life, ordinary sealing and packaging tape (BOPP biaxially oriented polypropylene) is an indispensable daily necessities in any enterprise, company, and personal life. However, compared with the current domestic situation, although there are many manufacturers, the technology is uneven. . Moreover, the technical content of the domestic tape industry is still at a very low stage, and the country does not have a clear choice for this. People often have a very ignorant understanding of tape. They think that the price is low and the stickiness is good. In fact, these are all wrong understandings and judgments.

So how to choose the quality of tape? In fact, there are two standards for the quality of the adhesive tape in use, one is the initial adhesion, the other is the holding force, and the two are inversely proportional. Under normal circumstances, the adhesive tape with a viscosity lower than No. 10 is less glue-coated, generally only about 20 microns, such as stationery tape, tape for general promotion and bundling. The initial adhesion of normal sealing tape is between 15-20, and the thickness of this tape glue is generally 22-28 microns. is a standard thickness. However, most of the tapes on the market are mixed with impurities, so the thickness increases. In order to cover the impurities, the glue is also mixed with toner, so the transparent tape appears egg-yellow and light green. This tape is generally inferior.
