LAMINATING

Laminating is the process of bringing two or more materials together and bonding them.  There are many variations on the methods for bonding the materials:

The most common is with the use of PSA (pressure sensitive adhesive) as a bonding agent.  The adhesive can be applied as 'transfer tape' which is adhesive precoated onto a release liner (with or without a carrier) or coated directly onto one of the surfaces.

Heat activation is often used to melt the surfaces or thermoplastic adhesive that was previously coated and get the materials to bond under the pressure of the lamination rollers.  Heat is the method of choice for selective lamination such as sealing bags.

Other forms of surface activation such as flame treating or corona treating can be used to bond materials. At this time, we do not offer corona treating or flame lamination.

Some materials such as filter papers respond to 'knitting' which involves passing the layers between rollers with a raised pattern that forces the fibers together and makes a bond.

CRC can laminate almost any web material from a filament to a 60" wide web with many of the processes mentioned above.  For webs wider than 10", we can combine adhesive coating, lamination, and slitting.  In the narrower widths, we can combine any number of processes such as multiple lamination, stripping, die cutting, embossing, and coating.
