 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 foam lamination 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 preparation 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.
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.
PLI can laminate almost any web material
from a filament to a 118" 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.
We specialize in the lamination of
all foam materials like PE polyethylene, PP polypropylene,
EVA, open-cell, closed cell, cross-link foam, rubber materials,
felts, fleece, nonwovens.
