- To create
a moisture barrier for refrigerated and/or dairy product labels that
protects the paper from absorbing excess moisture and becoming wet.
- For additional
strength and stability. (Makes labels more durable and tear-resistant.)
- For added
body and gloss on prime labels.
- To replace
costly pressure-sensitive stocks with a more economical paper/lamination
construction that does not sacrifice strength.
- To protect
expiration dates or data from being tampered with.
LAMINATING
MATERIALS MOST COMMONLY USED:
1. Non-pressure sensitive films that are glued in-line and on-press.
- Biaxially
oriented polypropylene (OPP) is economical and the most commonly used
laminating film. Available in thicknesses of .00050, .00075, .001.
- Polyester
films can be used for extra strength. Common thicknesses include
.00048, and .0092.
2. Self-wound,
pressure sensitive adhesive films without release liner.
- primarily
OPP, some polyester
- Moderate
to expensive in cost
3. Pressure-sensitive
adhesive films with release liners.
(Liners usually removed during laminating and discarded.)
- Materials
are intended to be primary face stocks for printing.
4. UV
Varnish
- Gives
laminated look, but has no extra body.
- Provides
less moisture protection than lamination.
TYPICAL
APPLICATIONS FOR LAMINATED LABELS:
- Dairy
or juice labels, bottled water, regional and specialty beverages (glass
or plastic containers). Any refrigerated product label.
- Meat
product packaging labels (lunchmeats, sliced meats, etc.)
- Specialty
tape or label constructions.
- Prime
labels (for added body, gloss, scuff resistance).
- Original
Equipment Manufacturers (OEM) product label.
