11. MANUFACTURER'S RECOMMENDATIONS
11.1

Film Types

This machine has been specifically designed to run the low temperature co-polymer films.
WARNING :
It is strongly advised that lower quality monomer (Regular) grades of laminating films are not used.
The excessive temperatures, high tensions and pressures these low quality films require to produce a
result will produce excessive wear and tear on your laminator.
11.2

Film Gauges

Your CRL40 has been engineered to use 1.5, 3 and 5 mil film.
Lighter gauges i.e. 1.5mil require greater heat input as their lighter bulk does not retain heat well
between the heat shoe and the laminating rollers. This requires evenly heated nip rollers to
compensate. They are very sensitive to temperature fluctuations and cold climatic conditions
especially when starting from cold. For best results use the following precautions:
- Allow a much longer warm up period.
- Lift temperature to 270 - 280 o F.
11.3 Stock Weight
Minimum weight of stock to be comfortably laminated is 50lb, lighter stock weights may
be laminated successfully but may begin to crease or exhibit "cockling" along the trailing edge.
Maximum recommended laminating gauge is 1/8", laminating heavier stock weights may cause the
nip rollers to come in contact with the heat shoes and upset the pressure settings of the laminating
rollers or damage the gearbox. Do not attempt to alter the factory set pressure settings.
