What is Thermal Film Lamination?

Question

I have seen photo albums which is said laminated with thermal film for greater protection

Answer 1

THERMAL LAMINATION (ENCAPSULATION):

Traditionally applied two sides at once. The films used are generally polyester based, and commonly available in a variety of film thickness from 33 micron up to 250 micron, with 75 micron being the most common. (1000 microns = 1mm). The polyester outer layer of the film has a heat activated resin coating - hence the term Thermal Lamination. The thickness of the polyester determines the stiffness of the film, and the quality of the polyester usually determines the clarity.
Thermal Lamination is generally short run, often 1 or a few items are processed. There are higher volume jobs where automated trimming is brought in to reduce unit costs.
The materials used in laminates can be the same or different. An example of the type of laminate using different materials would be the application of a layer of plastic film — the "laminate" —on either side of a sheet of glass — the laminated subject. On the other hand, plywood is a common example of a laminate using the same material. Examples of laminate materials include Formica and plywood. Formica and similar plastic laminates (such as Pionite, Wilsonart or Centuryply Mica) are often referred to as High Pressure Decorative Laminate (HPDL) as they are created with heat and pressure of more than 5 lbf/in² (34 kPa). A new type of HPDL is produced using real wood veneer or multilaminar veneer as top surface. Alpikord is one of these laminates produced by Alpi spa.

Laminating paper, such as photographs, can prevent it from becoming creased, sun damaged, wrinkled, stained, smudged, abraded and/or marked by grease, fingerprints and environmental concerns. Photo identification cards and credit cards are almost always laminated with plastic film. Lamination is also used in sculpture using wood or resin.
Laminate film is generally categorized into these five categories:

Standard thermal laminating films :

Low-temperature thermal laminating films ,
Heatset (or heat-assisted) laminating films ,
Pressure-sensitive films ,
Liquid laminates ,
PET Thermal Film ,
Bopp(BI-AXIALLY ORIENTATION POLY PROPELENE) Thermal Lamination Film.

Answer 2

Thermal lamination is a process, where an extrusion coated biaxially oriented polypropylene (BOPP) film, is laminated to printed paper by the application of heat & pressure. CFL’s unique thermal lamination film is made by extrusion coating of LLDPE or EVA or a blend of these polymers. Thermal lamination process is an effective alternative to the conventional wet lamination, where printed paper & plastic web are laminated together with the help of water based adhesive.

However the most important aspect of this innovation is the low melting thermoplastic that is extrusion coated on BOPP film. This thermoplastic has got to have excellent optics, very good flow ability, low melting point.
