what is packaging tape

the packaging tape material is BOPP (biaxial tensile polypropylene) film and glue, which is an indispensable article in the life of any enterprise, company and individual. The country has no perfect standard for the tape industry, only one industry standard, "BOPP pressure-sensitive adhesive tape for qb/t sealing". Production method of packaging tape: the packaging tape is based on the original BOPP film. After high-voltage corona, the surface of one side is rough, then coated with glue, and then divided into strips and small rolls. It is the tape we use daily. Adhesive tape glue is acrylic glue, also known as pressure-sensitive adhesive, and its main component is tincture grease. Classification of packaging tape: transparent packaging tape, color packaging tape and printing packaging tape. History of packaging tape: in 1928, transparent tape Richard drew, St. Paul, Minnesota, applied in Britain and the United States on May 30, 1928. Drew developed a very light, one press adhesive. The initial attempt was not sticky enough, so drew was told: take this thing back to your Scottish bosses and ask them to put more glue! (Scotland means stingy. However, during the great depression, people found hundreds of uses for this kind of tape, from mending clothes to protecting broken eggs. The principle of packaging tape: why can packaging tape stick? Of course, it is because it is coated with a layer of adhesive on the surface! The earliest adhesive came from animals and plants. In the 19th century, rubber was the main component of adhesive; in modern times, it is widely used Apply various polymers. The reason why an adhesive can stick to things is that its own molecules form a bond with the molecules of the object to be connected. This bond can firmly bond the molecules together. The components of adhesives are different polymers according to different brands and types. The material of packaging tape: 1. Backing is mainly OPP, PVC, pet, PE, etc. in China, it is mainly BOPP 2. Adhesive is the main material is natural (synthetic) rubber, and acrylic. What is pearl cotton? Pearl cotton, commonly known as EPE, is a new environmental protection packaging material with high cushioning, shock absorption and seismic resistance. It is flexible, light and elastic. It can absorb and disperse the external impact force through bending, so as to achieve the cushioning effect, and overcome the shortcomings of EPS (styrofoam), paper and plastic products, such as fragile, deformation, poor resilience and poor shock resistance. At the same time, EPE has a series of superior use characteristics, such as heat preservation, moisture-proof, anti friction, corrosion resistance and so on. After adding antistatic agent and smoldering agent, it shows its excellent performance. EPE has a unique molding process and does not need to use molds. In the process of sample preparation, it can not only change the design freely according to the requirements of customers, but also greatly reduce the mold cost of customers. In particular, under the special circumstances of large variety and small quantity of customers' products, it can better show the benefits brought by EPE, such as the comprehensive cost of optimized design is lower than the cost of styrofoam, paper plastic and other products; The sample preparation and production cycle is short, which can greatly shorten the delivery cycle; The shape design of the finished product is novel, beautiful, practical and efficient. At present, it is widely used in the packaging of it, electronics, electrical appliances, hardware, electromechanical, high-end audio-visual, precision instruments, high-end furniture and other products. Its excellent anti-seismic protection performance guarantees your product confidence. What is sponge rubber? Sponge rubber is a kind of porous elastomer material, which is usually called foam rubber, foam rubber or microporous rubber. It is the general name of various rubbers with pore structure. Astmd1055 and ASTM d1056 define and classify latex sponges and dry rubber sponges respectively, and formulate conventional physical property measurement methods. The standard defines that the pores of such porous materials should be throughout the whole material. According to the different pore structures, they can be divided into closed pores (pores are not connected with each other), open pores (pores are not completely separated from each other by the hole wall, and have a certain degree of connectivity) and mixed pores (both open and closed structures). Accordingly, microporous rubber mainly includes expanded rubber and sponge rubber. Due to different usage habits, the meaning of sponge rubber in the domestic scientific and technological literature does not distinguish the opening of bubbles. These devices give a certain play space to the materials that extend the outdoor aging from the closed hole mechanism. Sponge rubber has a wide variety of classification methods: 1. Classification of bubble mechanism: closed cell microporous rubber and open cell microporous rubber; 2. Classification of foaming ratio: low foaming (apparent density 0.5g/cm2) and high foaming (apparent density <0.5g/cm2); 3. Classification of rubber matrix: NR rubber, SBR rubber, DPDM rubber, NBR rubber, silicone rubber sponge, rubber and plastic sponge, etc Performance and performance classification: soft sponge, hard sponge, microbubble sponge, conductive sponge, magnetic sponge, water expansion sponge, composite sponge, etc. Compared with solid rubber, sponge rubber has many special and valuable properties because of its structural particularity, that is, porosity, such as: (1) small apparent density, light weight and material saving; (2) It is elastic and flexible, and has excellent sealing effects such as dust-proof and water-proof gas; (3) Improve the thermal insulation performance and have low thermal conductivity; (4) It improves the ability of absorbing impact load and has excellent cushioning and shock absorption performance; (5) Improve sound insulation and absorption effect; (6) Improve touch and comfort; (7) Physical properties vary widely. Sponge rubber with corresponding properties can be obtained by changing the apparent density or cell structure. Therefore, sponge rubber products are widely used in many aspects, such as sealing, shock absorption, heat insulation, sound insulation, printing and dyeing and even ion exchange. They are widely used in aviation, automobile, instruments, meters, household appliances and packaging industry. Its shape is plate-shaped, strip-shaped, tubular, roller, gasket, etc., with various specifications and shapes. Different use conditions require different hole structures and hole sizes. Therefore, it is required to make corresponding adjustments in formula design and processing technology to achieve the corresponding performance. What is acetate cloth tape?
