WHAT ARE COLD SEAL ADHESIVES?

Cold seal adhesives are water based natural rubber latex compounds primarily used to seal heat sensitive items such as chocolate bars.

The adhesive is normally applied wet to the substrate by a revolving gravure cylinder, immediately dried in an extended oven before it is reeled up at the end of the press.

The adhesive is usually applied to polypropylene film in a ‘window’ pattern that will allow the wrapper to be sealed adhesive to adhesive on the packaging line, without any heat being applied by the sealing jaws.
