A Film, Not Just a Gloss Coating
At a retail counter, a printed tube may pass through several customers' hands before someone purchases it. The lid is removed, the package is turned to inspect the label, and the finished surface repeatedly contacts neighboring products.
Those interactions can leave scratches, fingerprints and rubbing marks on an unprotected printed wrap.
Custom Laminated Tubes use a protective film bonded to the exterior paper wrap of a rigid cylindrical package. The film changes the surface's appearance, feel and resistance to certain types of wear.
The important distinction is between the laminated outer wrap and the structural paperboard beneath it. The film protects the printed surface; the wound paperboard body provides the main cylindrical structure.
Lamination is also different from applying a liquid varnish or aqueous coating. Both can affect the finish, but they have different constructions and performance characteristics.
Film Lamination
Film lamination involves bonding a thin protective film to the printed paper surface.
Depending on the specified material, the film may create a matte, gloss, soft-touch or other specialized finish.
The laminated paper can then be applied as the outer wrap of the tube, subject to the manufacturing process.
This construction can protect the printed artwork against certain handling and abrasion conditions. Actual performance depends on the film, adhesive, underlying paper and quality of the finished bond.
It does not make the entire paperboard tube waterproof or eliminate the possibility of surface damage.
Aqueous Coatings
An aqueous coating is a liquid-applied surface treatment rather than a separate laminated film.
It can produce different levels of sheen and offer some protection against rubbing, depending on the coating specification.
For relatively straightforward retail packaging, a suitable coating may be sufficient.
However, film lamination and aqueous coating should not be treated as identical merely because both can produce a matte or glossy appearance.
The differences between lamination and coating matter when approving the manufacturing specification, particularly when surface protection is an important purchasing requirement.
The packaging supplier specification mistakes that affect finished products often begin with apparently interchangeable finishing terminology.
