As a common material, Velcro is widely used in daily life. It has replaced the functions of many tapes and ropes and is highly suitable for the requirements of high - speed construction nowadays. Small dot - shaped Velcro is extensively used in children's "cutting - fun" toys and quiet books. How is this kind of Velcro made?
Without on - site observation, we won't know the customer's production process. First, the customer coats pressure - sensitive hot - melt adhesive onto the Velcro. After the Velcro cools down, it is sent to a die - cutting machine for die - cutting according to customized specifications. Then, the desired small dot products with pre - applied adhesive are obtained. The quality of the back adhesive determines the quality of the finished product. So, how should this adhesive be selected?
Our company has matched different grades for different customer applications. The requirements for hot - melt adhesives for die - cut Velcro not only include good initial adhesion, but also sufficient bonding strength to prevent the particles from falling off after re - warming. In addition, they should have good waste - stripping performance, making it easy to separate the waste materials. Our company has matched three products according to market demands, which can be accurately matched according to specific needs.
