II. Symbols

The symbol "/" for lamination, lamination methods include:

--Dry Lamination Dry Lamination Symbol "/dr.".

Dry Lamination, that is, after applying glue, the solvent in the glue will be fully dried by heating and exhausting, and then laminated in a "dry" condition.

--Solvent Free Lamination Symbol "/SF.".

Solvent Free Lamination is a method of laminating two substrates together on a solvent free laminating machine using a 100% solid solvent free adhesive, also known as reactive lamination.
--wet lamination wet lamination symbol "/wt.".

Wet lamination is a method of laminating two substrates together on a wet laminating machine, also known as reactive lamination, after the first layer of the substrate has been glued, without going through an oven.

--Extrusion lamination Symbol "/ex.".

Extrusion lamination, also known as salivary lamination, is the polyethylene, polypropylene and other thermoplastics in the extrusion laminating machine melt, from the flat head in the form of a thin film of uniform outflow, continuously coated on the substrate, by the pressure roller compression and cooling rollers cooled, made of two layers or more than two layers of composite film.

--co-extrusion lamination co-extrusion lamination Symbol "/co.".

Co-extrusion lamination is a process of producing a multi-layer composite film by using two or more extruders sharing a laminating die head.
