Chris Heiland, sales director at Teknipure, says: "The process is unique in that we use pressure and heat to create a 4mm border, and then we add an ultrasonic seal to the edge to provide a double seal with no fibres at the edges, which addresses loose fibre problems other manufacturers have with border-sealed wipers."
The wipers are available in two sizes of 9x9in (23x23cm) and 12x12in (30x30cm) in dry and pre-saturated versions.
All packaging is vacuum purged with nitrogen and labelled with solvent safe, cleanroom-compatible labels. The company says the packaging materials are compatible with the most demanding cleanroom environments. Bags are available in standard cleanroom grade LDPE. A reusable pail is also available for the pre-saturated wipers. For static-sensitive applications, a static shielding bag with ziplock seal is available, which eliminates tribo-charging of the wiper and the need for ‘hot plastic’ packaging in ESD regulated production areas. All packaging, cleanroom laundering and converting are done in a Class 10 cleanroom.
