Polyprepylene (PP) Lamination for Shopping Bags and Packaging

Lamination:

  • Available in a gloss or matte finish
  • Adds a considerable amount of strength and prevents tearing and cracking
  • Acts as a moisture barrier and prevent inks from rubbing off
  • Adds rigidity
  • Matte lamination scuffs more than gloss
  • Lamination is NOT ENVIRONMENTALLY FRIENDLY mixing two different materials that cannot be recycled
  • When printing on the inside of a bag (sheet) and lamination on the outside bag, certain problems can result
  • There are two basis styles of the laminating process: water process and heat process. Water process takes longer to dry and is not a good system where press approvals are required.
  • Lamination will often change the image color and affects color reproduction, sometimes adding a yellow or blue hue. Care should be used on very sensitive color jobs including four color process. A good pressman can some times compensate for the lamination but this is an art and not an exact process.
