What is a packing tape? Nmousewheel="return bbimg(this)" alt="" hspace="" onload="resizepic(this)" border="0" src="" class="lazy" original="" />
The packaging tape material is BOPP (biaxially oriented polypropylene) film and glue, and it is an indispensable item in any company, company and individual life.
The country does not have a perfect standard for the tape industry, only one industry standard, "QB/T 2422-1998 BOPP pressure sensitive adhesive tape for sealing."
Packaging tape production method:
The packaging tape is based on the original film of BOPP after high-pressure corona, after roughening one surface and applying glue, it is divided into small volumes after being divided into strips.
We use daily tape. Adhesive tape glue is acrylic glue, also called pressure-sensitive adhesive, the main ingredient is blusher.
Packaging Tape Category:
Transparent packaging tape, colored packaging tape, printing packaging tape three categories.
Packaging tape history:
1928 Scotch Tape Richard Drew, St. Paul, Minnesota, USA
Apply on May 30, 1928 in the United Kingdom and the United States, Drew developed a very light, compact adhesive, an initial attempt
Not sticky, so Drew was told: "Take this thing back to your Scottish boss and ask them to put some more gum!" ("Suge
"Blue" means "Hey." However, during the Great Depression, people found hundreds of uses for this tape, from making up clothes to protecting broken eggs.
It is very useful.
Packaging tape principle:
Why can packaging tape stick? Of course because it is coated with a layer of adhesive on the surface! The earliest adhesives came from animals and plants.
In the 19th century, rubber was the main ingredient of adhesives; modern polymers were widely used. Adhesives can stick things because of themselves
The molecules form bonds with the molecules of the objects to be connected, and the bonds can firmly bind the molecules together. Adhesive ingredients, according to different
Brands, different types, there are a variety of different polymers.
Packaging tape material:
1 Backing is mainly opp, pvc, pet, pe and other domestic mainly bopp
2 Adhesive The main materials are natural (synthetic) rubber, and Acrylic
What is pearl cotton?
EPE, commonly known as EPE, is a new type of environmentally-friendly packaging material with high-strength shock-absorbing and shock-resisting capabilities. It is flexible, light and flexible, and it can absorb and disperse external impact forces through bending.
To achieve the effect of buffering, it overcomes the disadvantages of fragile, deformed, poor recovery and poor shockproof performance of EPS (styrofoam), paper and plastic products. At the same time, epe has insulation, moisture, abrasion, corrosion resistance
Such as a series of superior use characteristics. Add anti-static agent, smoldering agent, it shows its excellent performance. EPE has a unique molding process and does not require the use of molds. In the process of sample preparation, not only can it be completely pressed
The customer's requirements are free to make design changes, and the customer's mold cost is greatly reduced. In particular, in the special case of a large number of customer products and a small number of products, epe can better show
Benefits, such as optimized design, lower overall cost than styrofoam, paper and plastic products; short sample preparation and production cycle, can greatly shorten the delivery cycle; finished product design is novel, beautiful, practical and efficient.
Now it is widely used in the packaging of IT, electronics, electrical appliances, hardware and electrical machinery, advanced audio-visual, precision instruments, high-grade furniture and other products, and its excellent seismic protection performance, so that your products can gain confidence.
What is sponge rubber?
Sponge rubber is a porous elastomeric material, often referred to as foam rubber, foamed rubber, or microporous rubber, which is a generic term for various rubbers having a perforated structure. ASTM D1055 and ASTM
D1056 defines and classifies latex sponges and pectin sponges, respectively, and formulates methods for determining physical properties. The standard defines that the pores of such porous materials should cover the whole material
Body, according to the different pore structure, can be divided into closed-cell (holes and holes do not communicate with each other), open-hole (holes and holes are not completely separated from the wall of the hole, with a certain degree of concomitant)
And mixed holes (both open and closed-cell two structures) three. Accordingly, the microporous rubber mainly includes two types of expanded rubber and sponge rubber. Due to different usage habits, the domestic scientific and technological literature "sponge
The meaning of "rubber" does not distinguish the open and closed cell structures of the cell. There are many varieties of sponge rubber and there are various classification methods. 1. Classification of cell mechanisms: closed cell microporous rubber and open cell microporous rubber
Glue; 2, expansion rate classification: low foaming (visual density â‰¥ 0.5g/cm2) and high foaming (visual density <0.5g/cm2); 3, rubber matrix classification: NR rubber, SBR rubber, DPDM
Rubber, NBR rubber, silicone rubber sponge, rubber sponge, rubber and sponge, etc.;
Performance and performance classification: soft sponge, hard sponge, micro bubble sponge, conductive sponge, magnetic sponge, water swelling sponge, composite sponge and so on.
Compared with solid rubber, sponge rubber has a lot of special valuable properties due to its structural speciality, ie, porosity, such as: (1), low apparent density, light weight material; (2), rich in
Elasticity and softness, excellent sealing effect such as dust-proof, waterproof, etc.; (3) Improved thermal insulation performance and low thermal conductivity; (4) Improved ability to absorb shock loads.
Excellent cushioning and shock absorption performance; (5) Improve sound insulation and sound absorption; (6) Improve touch and improve comfort; (7) Large range of physical properties, change in apparent density or cell structure
Corresponding properties to the sponge rubber. 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. In aviation, automobiles, instruments, instruments
There is a wide range of applications in the home appliance and packaging industries. The shape of the board, strip, tube, roller, washers, etc., a variety of specifications, different shapes. Different conditions of use require different holes
Eye structure and aperture size. For this reason, it is required to make corresponding adjustments in formula design and processing technology to achieve corresponding performance.

What is conductive cloth tape
Conductive fabrics were originally developed for the purpose of preventing the erroneous work of aerospace equipment by the United States Aeronautics and Space Development Agency (NASA). They are now widely used in the entire industry and not only protect the human body, but also
And can prevent the loss caused by the misuse of industrial equipment. The conductive cloth is composed of a metal surface layer (gold-silver-copper-nickel) covered with a surface composed of a chemical fiber, a natural fiber, and the like.
Metal fibers are woven to impart electrical conductivity without any change to the fiber's intrinsic properties. This ensures cutting and sewing processability, air permeability, flexibility, and comfort. Conductive cloth encountered
In the case of radio waves, reflections are made according to the nature of the object, absorbing, transmitting, and providing an excellent shielding effect.
What is 3MVHB Tape
3MVHB adhesive tape is an all-acrylic structure with super strong adhesive double-sided tape. It not only can seal off moisture and most solvents, but also can resist long-term ultraviolet and hot and cold cycles. The unique foam can be used as a pole.
