We're expert at impulse heat sealing thermoplastic films into complex shapes.

Our proprietary heat sealing technology produces seals that are stronger than the film components, and can seal films from 0.05 mil to 20 mil plus. We can achieve perfect seals in a fraction of the time other sealing technologies require.

Interested in replacing PVC, vinyl and other materials with greener, more sustainable choices? Trlby's design and impulse heat sealing expertise allows customers to update existing products with more advanced, less expensive materials.

Our technology heat seals without sacrificial layers / buffers or special coatings.

Trlby heat seal technology creates prototypes and pilot runs cost-effectively. No major investments in capital equipment are required.


Our skill and proprietary techniques create Heating Elements that can cut seal, make curvilinear seals, seal around ports, tubes and fitments, seal discrete areas in multiple layers of material, and seal dissimilar materials. Trlby Heating Elements can create thin seals that are stronger than the much thicker seals produced by other sealing processes. We have methods to maximize seal area, useful when strong seals are required in a confined space, and ways to balance seal strength with peelability.

Trlby technology is ideal for making products that require:

  • Air Cells
  • Bladders
  • Curved shapes and surfaces
  • Cut seals
  • Fittings, ports, and valves
  • Inflatable bladders

We can impulse heat seal all thermoplastics including:

  • Nonwovens
  • Polyesters
  • Polyethylene
  • Polypropylene
  • Polyurethane
  • Polyvinyl (PVC)
  • Laminates

Trlby precision Heat Sealing Elements are one of the technologically sophisticated components that differentiate our custom equipment from off-the-shelf machines. We use advanced analytical tools such as Finite Element Analysis to design every element.
