    With the advent of renewed and better technology, industrial development has changed in today's society. Recently, conventional adhesives for industrial purposes have been replaced by hot melt adhesives. Hot melt technology is widely used in packaging materials, diapers, medical pads, sanitary napkins, cardboard boxes of non-woven processing and manufacturing, as well as more than 10 kinds of such things. The following are different applications of hot melt adhesive technology.

    In the package, the adhesive should not be so strong as it will be removed after the product is removed from the package. You do not want to permanently seal the product in the box (or use any container). However, the adhesive should be strong enough to keep the product in the package in a completely safe and dry state (especially if it is food). There are specially designed industrial hot melt adhesive technology for packaging. These hot melt adhesive technology can be used for carton sealing, bag sealing, box sealing, tamper cover, box, tray manufacturing and so on.

    The use of nonwovens in clothing and other furniture is widely accepted because of its strength and elasticity. Hot melt technology has a certain effect in achieving these properties of nonwoven fabrics. Nonwovens are non-woven fabrics. The fibers used in the nonwoven fabric are bonded by heating and pressing. A special resin, called a binder, is used to hold the fibers together. The most common fibers used in the manufacture of nonwovens are cotton, rayon, polyester, wool, acetate and acrylic. Some of the binders for nonwoven fabrics are acrylic acid, vinyl acrylate, vinyl acetate and styrenated acrylic resins.

    The hot melt adhesive technology allows the molten thermoplastic resin to be used as an adhesive for assembly equipment. The strength of the adhesive will be achieved when the flexible resin is cooled, which is a good time-saving method for the manufacturer.

    For what we know, advanced technology always comes from the traditional practice. The conventional adhesives used (except for sticks, other thermoplastic resins that are conventionally used) are limited. They tend to melt at high temperatures and become brittle at low temperatures, thereby losing the strength of adhesion. In order to solve the temperature sensitivity of traditional adhesives, hot melt adhesive technology has been developed.
