1.3 PRINCIPLES OF OPERATION
Pouch Laminating Two sheets of film are put together with thermal adhesive facing
each other and sealed at one edge forming a pouch. An item to be laminated is placed
between these two sheets of film. The pouch with the item to be laminated is placed
on a sled and slid into the pouch laminator. The pouch laminator has one set of rolls.
The bottom roll is cold and driven. The top roll is heated and idles. When the sled with
pouch intact is slid into the laminator, the top and bottom rubber rolls come in contact.
The bottom roll pulls the sled through and the top roll heats the pouch and activates the
thermal adhesive. The film’s adhesive is pressed into the ink and fibers on the surface
of the item being laminated.
Mounting & Laminating One sheet of laminating film is sealed to the lead edge of a
mounting board. The thermal adhesive on the board and the thermal adhesive on the
film, face each other. An item to be mounted and laminated is placed between the film
and the board. When the board is slid into the laminator, the top and bottom rubber
rolls come in contact with the mounting board. The bottom roll pulls the board through
and the top roll heats the film. The film’s adhesive and the board’s adhesive are
pressed into the ink and fibers on the surface of the item being mounted.
Mounting – Only The mounting board has a thermal adhesive on one side. An item to
be mounted is placed on the thermal adhesive side of the mounting board. A release
liner sheet with silicon coating on one side is placed over the surface of the item and
covering the entire board (with the silicon surface facing item and board to prevent
adhesive from the mounting board transferring to the top heated laminating roll). When
the board is slid into the laminator, the top and bottom rubber rolls come in contact with
the mounting board. The bottom roll pulls the board through and the top roll heats the
item to be mounted and the mounting board. The board’s adhesive activates and is
pressed into the ink and fibers of the item being mounted.
