F-217 Foam Primary Liners

As the inventors of the industry-standard F-217 closure liner, the three-layer coex with solid skin and a foam core, Tri-Seal knows what it takes to engineer foam-based liners that deliver critical performance attributes. For example, Tri-Seal offers a variety of liners that are ideal for continuous thread or child-resistant closures where resealability is important. These are also the liners of choice for minimizing leaks in dispensing closure applications, such as trigger sprayers.

With its three-layer coex with solid skins and a foamed core, these primary liners offer smoother contact surfaces for improved sealing and are recommended for a broad range of products including:

  • Pharmaceuticals (over-the counter medication)
  • Chemicals (household, industrial and agriculture)
  • Cosmetics

Available in rolls or die cut pieces.

Here are just some of the features and benefits of F-217 Liners:

  • Tri-Seal is the manufacturer of the industry standard F-217 primary foam liner
  • Wide range of foam densities to meet performance objectives
  • Polyolefin foam options: LDPE, HDPE, LDPE/EVA, PP
  • Compatible with PET, PE, PP, PVC, PS, glass, aluminum and steel containers
