Hot melt adhesive stands out among many adhesives and is widely used in various industries. 

The reason is very simple. Hot melt adhesive has excellent bonding strength, which is difficult to cause harm to human body even if it is exposed for a long time. It has the characteristics of environmental protection, which is unparalleled superiority of other adhesives. 

Hot melt adhesive has made a great contribution to the fight against COVID-19 epidemic. With its excellent performance, it plays a key role in masks and protective clothing. It can not only bond non-woven fabrics, breathable films and other materials, but also meet the use standard of Plastic Polypropylene (PP) Melt-blown Special Material, which can effectively stop the spread of viruses and reduce the harm of toxic substances, and ensure the health of medical staff! So in addition to these two kinds, today we will uncover several common applications in life. 

First, direct contact with the skin, surgical hole towel (high adhesive strength requirements) structure: generally woven cloth and other materials are used as the base material, coated with medical zinc oxide or transparent hot melt adhesive to make it roll, which can be generally divided into three types: ordinary, waterproof and sports. White cotton cloth, non-woven fabric, PE perforated film, cotton paper and artificial silk are often used as the base materials to make corresponding medical tapes. Good adhesion, good skin adhesion, excellent anti-aging performance, moderate unwinding force and no sensitization. In addition, the surface of some substrates will be coated with unwinding agent, which is helpful to reduce the resistance when unwinding. Glue application method: Generally, most of them are directly coated with the substrate, and a few of them are coated with release paper or rubber roller before transfer. Width of base material: mostly between 80cm and 120cm. Production speed: mostly at 20-50m/min. After unwinding, cutting and rewinding, the finished product is obtained. 1. Medical tapes: generally used for dressing and fixing catheters, such as white cotton tapes, sports bandages, silk tapes, PE perforated film tapes and tissue tapes.

2. Wound application is generally composed of medical non-woven fabric or medical PE/PU film coated with adhesive, absorbent pad and isolation film, and is used for fixing surgical wounds or dressings. Commonly, there are infusion patches, band-AIDS, dressing patches, etc.

Second, non-direct contact with skin, medical composite products (ordinary or high-strength structural adhesive) Third, sterile packaging bag "medical paper bag" scope of application: mainly used for sterilization packaging of hospitals, clinics and various medical devices and accessories. Features: Good packaging scheme design, which can provide flat and three-dimensional paper bags with no coating, water-based adhesive coating, hot melt adhesive mesh coating and hot melt adhesive frame coating. Unique easy peeling design can provide obvious visual heat sealing transfer. High-performance heat sealing effect can provide uniform sealing strength and safe and clean peeling effect. Characteristics of medical frame coating products: good bacteria resistance, water resistance, frame gluing design and good heat sealing. Printed with sterilization mark, convenient and safe to use. Material structure: coated paper+coated paper. In the eyes of the public, hot melt adhesive should be used in many industries, but it is not. It is being fully integrated into our lives and applied at all levels. In a word, hot melt adhesive is one of the most widely used environmentally friendly adhesives. In addition to the medical industry, hot melt adhesive also plays its "perseverance" character in other industries.
