   We can use the major industries are double-sided tape, in different occasions may use the results, the results are not necessarily satisfied, then why are there double-sided tape such a big gap?
   Double-sided adhesive is the main reason is the use of glue is quite different, the common glue is divided into double-sided adhesive glue and water glue, hot melt pressure-sensitive adhesive, how to distinguish between double-sided adhesive glue and water glue, hot melt Now let's take a brief look at their features.
   Double-sided adhesive glue is a water as a solvent to acrylic or polyurethane resin through a special emulsion equipment, emulsified from its biggest advantage is: variety, environmental protection, low prices, and now there are many coatings are water-soluble glue, for example: The general water-soluble PA, PU water-soluble rubber film, oil sense of sense of color, scraping color paste and other functional slurry water-soluble with its functional, environmental protection, and low prices, will be the future coating. The shortcomings of the direction is poor film formation, washing fastness is poor, PU can not paste hot air plastic, not fit sponge, foam and other foam products.
   Double-sided adhesive rubber is an oily solvent (toluene, DMF, butanone, etc.) as a solvent, acrylic or polyurethane dissolved. Its advantages are good film-forming, good fastness, PU can be hot hot plastic, is currently widely used coating glue. The disadvantage is due to the use of oily solvents, so there is a lack of environmental protection, especially now oil prices, resulting in oil prices all the way Biao lang, most of the coating because of the high cost of the cost, so the use of relatively poor oil solvent Environmental protection is not up to standard, and with the national environmental standards to further improve, so the environmental requirements of the coating glue is getting higher and higher.
   Double-sided hot-melt pressure-sensitive adhesive is a kind of pressure-sensitive adhesive, mainly made of synthetic rubber and resin and rubber oil mixed into a molten state and then coated on the cotton paper, cloth or plastic film and other substrates made Of a new type of adhesive tape, low cost is its greatest advantage, the defect is the viscosity of the temperature by the more obvious. Mainly used for all kinds of sealed, sealed boxes, paper packaging, beverage bottle labels, sealing aluminum foil, flexible packaging and other packaging; green paper pallets, etc., to adapt to all kinds of materials.
