Hot melt adhesive film is a widely used product in the industry nowadays. Still, people often confuse it with pressure-sensitive adhesive tape, but they are different.
Hot melt film is a kind of adhesive that needs to be heated to produce stickiness, but the pressure-sensitive tape is different. It has a certain initial stickiness, as long as applying a certain pressure can produce a certain bonding effect.
Hot melt films and pressure-sensitive tapes are completely different in terms of the raw materials used. The common hot melt adhesive film is usually made of EVA, TPU, PES, PA. Pressure-sensitive adhesive tapes are made from SBS and SIS elastomers, so they are completely different in terms of raw materials.
From a morphological point of view, hot melt adhesive films are generally packaged in rolls or slit into fixed-width tapes. The pressure-sensitive adhesive tape is more common in tape, commonly double-sided tape, or transparent tape.
Therefore, hot melt adhesive film and pressure-sensitive adhesive tape are completely different in the raw material formula, product form, usage, and occasion. However, a hot melt pressure-sensitive adhesive product combines the advantages of hot melt adhesive and pressure-sensitive adhesive. It can be used on some occasions with high requirements for adhesive strength while having initial adhesion.
