The choice of pressure sensitive tape

Ordinary packing tape in daily life (BOPP bidirectional tensile polypropylene) is an indispensable daily supplies in any enterprise, company, personal life, but relative to the current domestic situation, although many manufacturers, technology is uneven.

Moreover, the content of the domestic tape industry in technology is still at a very low stage, and the country does not have a clear choice. People’s understanding of tape is often in a very ignorant stage, that the price is low, feel viscosity is good, in fact, these are wrong understanding and judgment.

Chemical flame retardants

So how do you choose good or bad tape? In fact, the adhesive tape is good or bad in use there are two standards, one is the initial adhesive force, one is the retention force, the two are inversely proportional. Under normal circumstances, the adhesive force is less than 10 adhesive tape is coated with glue, generally only about 20 microns, such as stationery tape, ordinary promotional binding tape. The initial adhesive force of normal sealing tape is between 15-20, and the thickness of this adhesive tape glue is generally 22-28 microns. It is the thickness that meets the standard. But most of the tape on the market are mixed with impurities, so the thickness increases, to shield impurities, glue also mixed with color powder, so transparent tape appeared egg yellow, light green, this kind of tape is generally inferior.

How to distinguish good from bad for colored tape?

For colored tape, generally yellow and earth yellow more. The adhesive is pinched and then quickly pulled apart, you can pull out one side of the adhesive, you can see the purity and transparency of the original film. You can also look at the thickness of the glue. If no glue is pulled apart or pulled apart punctually, there are a lot of impurities in the glue, and the glue has no cohesion. Second, the moisture is too much, has been volatilized, at this time the initial adhesive force of this tape has declined very much, feel can be distinguished. In fact, there are many ways to distinguish between good and bad tape, as long as you pay more attention to in life, you can distinguish the good and bad tape.

How to identify the beauty paper pressure sensitive tape true or false

In daily life, how do we distinguish the beauty of paper pressure sensitive tape is true or false?

First, the pair of adhesive pinch and then quickly pull apart, you can pull out one side of the glue, you can see the purity and transparency of the original film. The most important thing is to see the thickness of the glue. If no glue is pulled or punctured, there is a lot of impurities in the glue and the glue has no cohesion.

Two, too much water, has volatilized, at this time the initial adhesive force of this tape has declined very badly, feel can distinguish. The color of the whole roll of good tape is not much different from the color of the last one, because the good tape has a strong shelter, there is no color superposition.

water-based pressure sensitive adhesive

Three, look at the tape surface, tape just after the strip into the finished product when there are bubbles, placed a week after the bubble will basically disperse, pure tincture of grease glue tape surface smooth, without any white spots, mixed with impurities of the tape has a lot of irregular distribution of white spots, hand pressure does not disperse, is not the same as the bubble.

Four, the choice of tape must see clearly the width of the tape and the thickness of the tape, the formal enterprise production of tape paper tube are using a higher density of paper tube, cut without paper, and the thickness of the paper tube below 100 meters of tape is 3 mm, 100 meters above is 4-5 mm, and small enterprises to deceive consumption using thick paper tube, Usually the thickness is up to 5-7 mm thickness, so as to be relatively large in appearance, but the thickness of the glue is obviously compared out.

Five, do not feel the viscosity by hand alone, because the doped tape is very high when there is no volatilization, to paste the object with tape and then quickly open to see the retention force, repeated paste several times and then touch with the hand, it will obviously feel the decline in flexure.

The most important thing is to see the thickness of the glue. If no glue is pulled apart or spot-pulled apart, there is a lot of impurities in the glue and the glue has no cohesion. Second, there is too much water and it has been volatilized. At this time, the initial adhesive force of this sealing tape has been reduced very badly, and the feel can be distinguished. The yellow sealing tape is coated on the object. The better the masking, the thicker the glue and the better the quality.

The best sealing tape adopts the way of soft cutting and transferring glue, and there is no line situation (the ink leakage and less printing of printing sealing tape is related to the printing press).

Look at the surface of the sealing tape, sealing tape has just been divided into finished products when there are bubbles, placed a week after the bubble will basically disperse, pure tincture of glue sealing tape surface smooth, without any white spots. The sealing tape mixed with impurities has a lot of irregular distribution of white spots, which are not dispersed by hand pressure and are not the same as bubbles.

Properties and applications of Acrylic Pressure Sensitive Adhesive

Pressure sensitive adhesive (PSA) is a kind of adhesive that is sensitive to pressure and can be pasted without heating or solvent activation, as long as the contact pressure is slightly applied. Often made of pressure sensitive adhesive tape and adhesive sheet, convenient construction, easy to stick, not difficult to remove, peeling without damage, people commonly used medical adhesive paste and insulation tape is the earliest, the most typical pressure sensitive adhesive products.

pressure sensitive acrylate adhesive

Pressure sensitive adhesive generally has rubber type and synthetic resin two categories, acrylic pressure sensitive adhesive belongs to synthetic resin type. Because of its many advantages, it is in a leading position among pressure sensitive adhesives, and acrylate pressure sensitive adhesives are the most productive ones among acrylate adhesives.
Properties of pressure sensitive adhesives

Acrylic pressure sensitive adhesive is colorless transparent slime. The main difference between it and rubber pressure sensitive adhesive is that it can not add adhesive resin and plasticizer and other components. Its main characteristics are as follows:

(1) Mild pressure or acupressure can achieve effective adhesion.

(2) with oxidation resistance, oil resistance, solvent resistance and other excellent performance; All kinds of materials have a certain adhesive relay; Even difficult materials will stick together.

(3) Good transparency; It has high peeling strength and can withstand shock and vibration.

(4) non-toxic and harmless, no impact on the skin, medical adhesive tape can be prepared.

(5) Various functional groups can be introduced through copolymerization, so that the adhesive force and the cohesion of the glue itself are larger.

(6) The initial adhesion and wettability is not as good as rubber pressure sensitive adhesive. Most of the heat resistance, solvent resistance, durability is poor.

Application of pressure sensitive adhesive

Acrylic pressure sensitive adhesive has been widely used because of its good durability and appearance. Solution acrylic pressure sensitive adhesive is mainly used for making pressure sensitive film with plastic film as the back material, pressure sensitive tape, double-sided pressure sensitive tape and foam material pressure sensitive adhesive processing products, can also be directly coated adhesive paste.

Used for all kinds of plastic film and metal foil paste, metal and non-metal material paste, metal or plastic nameplate paste, label paste, etc. Solution pressure sensitive adhesive contains organic solvents, so it should be stored in a closed container, and pay attention to fire prevention.

pressure sensitive adhesive

The emulsion pressure sensitive adhesive is mainly used to make labels and pressure sensitive film, pressure sensitive adhesive tape, decals and other products with paper as the back material. Compared with solution type pressure sensitive adhesive, it has poor water resistance, moisture resistance, heat resistance, poor wettability of plastic film and other shortcomings. In recent years, a lot of research and development work has been done abroad, such as the use of new monomer copolymerization; Seed emulsion polymerization method was adopted.

The wettability of pressure sensitive adhesive to non-polar substrate and adhesion to difficult material were improved by using adhesive resin emulsion. Using reactive emulsifier or soap-free emulsion polymerization;

Improve the solid content (up to 60%~70%), speed up the drying speed, so that the performance of acrylic emulsion pressure sensitive adhesive has basically caught up with the solution type pressure sensitive adhesive, the product field has been expanded from paper base products to directional stretching polypropylene packaging tape, a variety of difficult to stick polyene substrate products and peeling labels, etc. It is estimated that this kind of pressure sensitive adhesive will have a great development in the next few years.

Why is some BOPP Tape light yellow?

BOPP tape is suitable for ordinary product packaging, sealing and bonding, gift packaging, etc. Depending on the color, there are different uses. Transparent sealing tape is suitable for carton packaging, fixing of spare parts, binding of sharp objects, art design, etc. Colorful sealing tape provides a variety of color options, in line with different appearance, beautiful needs; Sealing tape can be used for international trade sealing, express logistics, online shopping malls and other well-known brands.

BOPP film itself is transparent, and ordinary transparent tape is light yellow, because it uses the glue – pressure sensitive glue, usually orange, beige, if daubed with a small amount, there is no change, but a lot of it, the color will deepen, especially the BOPP tape film layer by layer, will gradually show light yellow. And super transparent tape can do approximately colorless, and will not yellow, in addition to the use of a very good film, high transparency of the glue, after special glue processing, super transparent.

Natural glue

As the industry’s packaging requirements continue to improve, there are many scenes in which super clear tape can present better visual effects. It has the same performance as ordinary transparent tape, but its unique high transparency is not available to other tape.

For example, Raxwell super permeable box sealing tape with bidirectional stretching polypropylene film (BOPP film) as the base material, on the base material side evenly coated with a layer of pressure sensitive adhesive (acrylic glue). BOPP film colorless, tasteless, with excellent transparency, so this kind of tape is also called BOPP tape, transparent visibility is good, low fog point, can clearly see the texture behind.

Of course, poor quality and cheap film transparency is not high, and the glue is easy to yellow, will cause the whole volume looks yellow.

Industrial packaging – BOPP tape

First, the definition of tape

Step 1 Define

Tape is composed of substrate and adhesive two parts, through bonding to make two or more disjointed objects connected together.

The surface is coated with adhesives that originally came from animals and plants. In the 19th century, rubber became the main component of adhesives. Today, a wide variety of polymers are used. Adhesives can stick because their molecules form bonds with the molecules of the object to which they are attached. These bonds hold the molecules together firmly.

Step 2 Sort

(1) According to the base material, it can be divided into BOPP tape, PVC tape, duct tape, kraft tape, American paper tape, fiber tape, PE foam tape, etc.

(2) According to the scope of application, it can be divided into warning tape, carpet tape, electrical tape, protective film paper glue, winding film tape, sealing tape, module tape, etc.

(3) According to the market penetration rate: can be divided into ordinary tape, special tape.

(4) According to the application environment temperature: can be divided into low temperature belt, room temperature belt, high temperature belt.

(5) According to the stickability: single-side tape and double-side tape.

Films

Two, BOPP tape

One，Define

BOPP tape is based on BOPP bidirectional tensile polypropylene film as the base material, after heating evenly coated pressure sensitive adhesive emulsion, so that the formation of 8μm—-28μm adhesive layer, is light industry enterprises, companies, personal life indispensable supplies.

The state has not a perfect standard for the belt industry, only one industry standard “QB/T 2422-1998 BOPP pressure-sensitive adhesive tape for sealing boxes”, the BOPP original film after high voltage corona treatment, one surface formed rough, and then glue coated on it, the first to form a mother roll, and then through the strip machine cut into different sizes of small rolls.

Two，Unit price calculation method

Specifications of BOPP sealing tape are expressed as “width x length x thickness”.

“Width” is the width of the belt, expressed by mm, among which the commonly used specifications are: 50mm, 48mm, 45mm, 40mm, 30mm, etc.;

“Long” refers to the total length of the tape after being pulled apart, which is generally expressed by m or y (1y=0.9144m). Common lengths include 50m, 100m, 200m, 500m, 80Y, 100Y, etc.

“Thickness” refers to the total thickness of BOPP original film + adhesive layer (unit: micron, μm), commonly used 45 ~ 55μm. For example, 50mm x 100m x 50μm.

Calculation method of unit price of each roll of adhesive tape: adhesive tape industry usually uses “yuan/square meter” to calculate the price of adhesive tape, then “price of each roll of adhesive tape = width (m) * length (m) * square price”.

Three, the characteristics of BOPP tape

1. It has strong tensile strength. Due to the directional effect of molecules, crystallinity is improved, tensile strength, impact strength, rigidity, toughness, moisture resistance, transparency are higher, film cold resistance is also higher, can prevent product leakage or damage in transportation.

2. Good printing performance. It can be printed, including monochrome, two-color and three-color, and can also print the trademark logo and the name of the enterprise, so as to play the role of forging and enhancing the visibility of the enterprise.

3. With high transparency, good gloss, high adhesion, smooth sealing, light quality, and non-toxic, odorless, safe, performance price is good.

4. The comprehensive performance is better than moisture-proof cellophane, polyethylene (PE) film, PET film.

pressure sensitive adhesives

Four, the choice of BOPP tape

1. The choice of tape

There are many kinds of tape, and there are many kinds of adhesive on the surface, so the performance and strength of various brands of tape are different, so the following factors need to be considered when purchasing tape:

(1) Microporous adhesive: Due to the adhesive tape action, the adhesive water on the surface of the adhesive tape seeps into the adhesive after the adhesive tape is glued and dries quickly, making the adhesive tape become a part of the adhesive tape. Therefore, the microporous adhesive surface is very important for the selection of adhesive tape. If the microporous or hygroscopic force is larger, it is necessary to use adhesive tape with rapid condensation, otherwise, use adhesive tape with slower condensation speed or tape with more adhesive.

(2) Initial adhesion strength and holding force: there are two standards for the glue quality of adhesive tape in use, one is the initial viscosity force, one is the holding force, the two are inversely proportional. Under normal circumstances, adhesive tape is less than 10 glue coating, generally only about 20 microns, such as stationery tape, ordinary promotional binding tape; The initial adhesive thickness of normal sealing tape is generally 22-48 microns.

2. The choice of colored tape

Generally yellow and earth yellow more. Pinch the adhesive tightly and then quickly pull it apart, you can pull the glue off one side, you can see the purity and transparency of the original film, you can also see the thickness of the glue. If no glue is pulled apart or pulled apart punctually, there are a lot of impurities in the glue, and the glue has no cohesion; Two is too much water, has volatilized. At this time, the initial adhesive force of this tape has fallen very badly, feel can be distinguished.
