Hot Melt Pressure Sensitive Adhesive Production Line

Video

1. Hot melt pressure sensitive adhesive is a kind of hot melt adhesive with long time surface adhesion or long open time.

Hot melt pressure sensitive adhesive packaging than the general plastic rubber or no surface adhesion of the hot melt adhesive is much more difficult, there are factories will directly reactor mixing good pressure sensitive adhesive discharge directly into the metal hard disk coated with Teflon or silicone. After waiting for the hot melt pressure sensitive adhesive to cool down, it will be peeled off the metal disk, and then packaged with release paper or film, either directly or after cutting into small pieces. The common packaging weight is about 500g to 5000g per piece.

2. Barrel packaging When a large amount of adhesive is used or a faster melt speed is required, it can be considered that the molten hot melt pressure sensitive adhesive will flow directly into a silicone-coated 55-gallon paper drum with a top opening lid or a metal drum coated with epoxy resin. Packaging weight per pail is approximately 150 to 200 kilograms. The use of pail packaging must be accompanied by a pail melting system. The melting system consists of a disk with finned heating elements, which are inserted directly into the drum, leaving the unglued space.

The disk heats up and melts the adhesive side while pressing down, and the melted hot-melt pressure-sensitive adhesive is pumped through a gear pump into the tubes and back section of the gluing equipment.

3. The way of using hot melt adhesive film wrapping: Jiji film wrapping machine or Jiji pressure sensitive adhesive wrapping machine.

Pillow or sausage wrapping is a thin plastic film with no adhesive on the surface of the hot melt pressure sensitive adhesive. Pillow or sausage-shaped packaging is marketed in two common packaging systems.

The Fargo wrapper is a direct wrapping of a molten hot melt pressure sensitive adhesive and a plastic wrapping material through a co-extrusion die at high temperatures. The wrapped product is then cooled in a waterway after the adhesive strip has been crimped into small segments by a cyclic die press.

After the strip has cooled down, the strip is blown dry by air, and then each small piece of pillow or sausage-shaped hot-melt pressure-sensitive adhesive on the strip is ripped off by two rotating wheels at unequal speeds to obtain a single pillow or sausage-shaped piece of adhesive. The Jiji packaging machine pours the molten hot melt pressure sensitive adhesive directly into a preformed PE/EVA co-mingled plastic strip, seals it, and then cools it directly into an ice water channel.

After cooling, it forms a single pillow or sausage-shaped adhesive strip with no sticky surface.
