What is Cold Seal? Cold seal allows you to close your flexible package simply by applying pressure when your product is being packaged. A registered pattern cold seal is pre-applied to the substrate, providing an alternative to heat seal on many products such as ice cream, chocolates and candy, to name a few. Not only does cold seal allow you to increase your production speeds, it also allows you to form a finished flexible package without the costs and challenges associated with heat seal technology.

How would it benefit? With Cold Seal you can expect to reduce packaging waste and decrease set up time. Because no heat is needed set up material is kept to a minimum, there is no waiting for heads to heat and no adjusting temperature for speed. From wrapper one to one million your wrappers and equipment are ready. Our process ensures our in-register pattern cold seal adhesive is applied at a consistent coat weight giving the best hermetic seals available in the market. Bar wrappers are high barrier and available in clear, metallized or white structures with a clear or matte finish. 

Product Applications for Cold Seal Adhesives:

  • Heat sensitive products such as chocolate and ice cream
  • Very high speed packaging machines
  • Combination of both: high speed packing for heat sensitive products
  • Medical packaging materials
  • Industrial applications
