Thermal File Lamination

THERMAL FILM adheres to the substrate when the adhesive is activated by heat. With a few exceptions – we only use thermal film on paper substrates and offset inks.

FINISHES are usually either gloss or dull.

Glueable, foil stampable, scratch resistant, UV inhibited, layflat, dry erase and even microbial films (films that inhibit germ growth) can be applied.

FILM THICKNESSES are: 1.2 mil, 1.7 mil, 3 mil, 5 mil and 10 mil.

Each mil is a point. 1.2 and 1.7 mil are usually the maximum thickness used for 1 sided applications (unless the substrate is at least 18 pt) due to curling issues. But – all thicknesses can be applied both sides.

We can laminate from business card size up to 38” width and to just about any length (depending on paper thickness) with thermal film.

FLUSH TRIM – The piece is printed multiples up on a larger sheet and will be trimmed to size once the sheet is laminated. This is usually the least expensive way to laminate a high volume piece job.

We require a minimum of 1/2” of gripper/guide space on all 4 outside edges of a sheet. The film will go past the image area but not all the way to the edge of the sheet. This way, there is no film hang off to impede good registration when trimming.

Flush trims can be done on one sided or two sided lamination.

EDGE SEALED OR HEAT SEALED – The piece can be printed multiples up on a larger sheet but must be trimmed to size prior to lamination. Typical edge seals are 1/8” to all 4 outside edges although special size edge seals can be done (for example – leaving 3/4” on the left hand side for holes).

Paper thickness is important for edge seals because it is difficult to get a good seal on paper that is too thick.

We can do an edge seal with 1.5 mil, 3 mil, 5 mil and 10 mil laminates. Edge seal lamination is always 2 sided.

If a powder is used, use a small granular powder and dust both sides of sheet before laminating.

If a coating is used, use a coating recommended by your manufacturer for thermal lamination. Also, most coating manufacturers recommend a 72-hour curing time prior to laminating.

DIGITALLY PRINTED SHEETS – tests need to be done on the inks and papers intended to be used on the live job. Film manufacturers are working on different adhesive formulations, but so far, not all digital inks work with the new formulas. It’s always a good idea to make sure adhesion will not be a problem before you’re given a price to your client. Pressure sensitive film is an alternative that works – but it is more costly.
