How about the price of tape?
- Each tape price calculation method: the tape industry usually use "yuan / square meter" to calculate the price of adhesive tape, calculate the price of adhesive tape formula: "each tape price = width (m) * length (m) * square price"". The price of the adhesive tape needs to be variable according to the cost, because the BOPP film and glue belong to the petroleum products, and the price is uncertain.s
How does the electrician use waterproof insulation tape?
- First, open the package and uncover and remove the insulating layer (layer of film) of the waterproof tape. Take the waterproof tape at the exposed 2CM of the conductor, lengthen 200%, and use the semi winding (half pressure half)s

Selection of tapes
- So how do you choose the tape? In fact, the adhesive tape in the use of good and bad there are two criteria, one is the initial viscosity, one is to maintain the force, the two are inversely proportional. Under normal circumstances, adhesive force less than 10 adhesive tape is glue coated, teach less, usually only about 20 microns, such as stationery, tape, ordinary promotion belt used adhesive tape. The initial adhesive force of the normal sealing tape is between 15-20. The thickness of the adhesive tape is 22-28 microns. Is the standard thickness. But the tape on the market are mostly mixed with impurities, so the increase of the thickness of shielding impurities, the glue is also mixed with the toner, so transparent tape appeared egg yellow, light green, this tape is generally inferior.s

What are the tapes for packing tape?
- There are many kinds: packing tape series: transparent adhesive tape, color adhesive tapes
The production of transparent tape material is what to do
- The base material of the sealing adhesive tape is BOPP film.BOPP is a very important flexible packaging material, and has been widely used. BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency. It is a high quality substrate for making transparent sealing tape. BOPP film has low surface energy, and it needs corona treatment before gluing or printing. However, the BOPP film has good printing adaptability after corona treatment. It can be printed by printing and has a beautiful appearance, so it is often used as the surface material of composite films. BOPP film is also inadequate, such as easy accumulation of static electricity, no heat sealing and so on. In the high-speed production line, BOPP film is easy to generate static electricity. Electrostatic eliminator is necessary. In order to obtain the BOPP heat seal film, can be on the surface of BOPP film after corona treatment coating heat sealing resin glue, such as PVDC, EVA latex latex, can also be coated with solvent glue, coating or extrusion method can be applied to the production of extruded composite heat sealing film BOPP. The film is widely used in bread, clothing, footwear and other packaging, and cigarettes, books cover packaging. The tear strength of BOPP film increases after stretching, but the secondary tearing strength is very low. Therefore, no cut can be left at the ends of the BOPP film, otherwise the BOPP film is easy to tear when printed and compounded. BOPP coated self-adhesive, we can produce our commonly used sealing tape, tape sealing tape, is a larger amount of BOPP market.s
