  • Labeling: Commonly used in label manufacturing, allowing for easy peeling and placement.
  • Construction: In roofing and insulation products, release liners help manage adhesive properties during installation.
  • Food Packaging: Employed in food packaging to maintain hygienic conditions while providing options for easy opening.
