They found paper products didn’t offer enough protection and would tear, cardboard was too thick and abrasive, whilst plastic and polystyrene retained dirt and grit on the surface so scratched the glass. Films offered the right level of protection and prevented scratching and cracking, however they restricted sliding making it difficult to separate the panes when stacked.
The customer couldn’t risk a new product development being unsuccessful, so they contacted Lesterdale to discuss the possibility of sourcing an existing technical fabric that had the protective qualities of a film with the added properties of a smooth non-abrasive finish for easy separation.
Lesterdale took the time to understand the application and the processing environment and established the following requirements:
- Supplied in mill rolls
- Ding protection
- Smooth finish
- Tear resistant
- Water resistant
- Repels dust and grit
