Belts

Belts are widely used for:

  • Heat sealing belts for: packaging equipment, bagging
  • Industrial belts for: food processing
    (taco belts, frozen foods)
  • Condiment bags
  • Pharmaceutical
  • Conveyor belts
  • Dryer Belts

Performance characteristics:

  • Non-stick
  • Low friction
  • Dimensional stability
  • Chemical resistance
  • High dynamic strength
  • Lightweight
  • Flex fatigue resistance


Fiberglass Industrial Belts and PTFE Heat Sealing Belts

Custom made industrial and heat sealing belts for food processing, packaging equipment, and bagging

Belting materials are based on glass fabric material coated with PTFE or silicone. They are made to your custom width and length requirements. 

BELT OPTIONS

PTFE Heat Sealing Belts– referred to as “endless belts come in 1-ply and 2-ply, are typically 3“ or narrower in lengths of approximately 26” – 126” made to your specifications. Edges tend to be “natural”. They are used for band sealing applications.

Fiberglass Industrial Belting (conveyor belts) 


Fiberglass Industrial Belting– also known as “conveyor belts” are typically 1-ply, in widths of 4” or wider any length. They are joined in many ways including: alligator splice, overlaps, sealed and sewn, grommets, and reinforced. Belt edges can be modified. They are used for mechanical fastener applications.
