Wet Lamination Process

The substrates making up the webs may consist of films papers or aluminum foils.

Wet lamination process. However the material properties in the wet lamination process are not as good as with other processes. Wet lamination showed to have the following advantages. The laminate then passes through the chilled nip of the combiner roll cooling the plastic layer which solidifies. The large proportion of manual production requires well trained specialists and careful quality control.

Particles and other surface contaminants are washed away by water. Laminating is the process through which two or more flexible packaging webs are joined together using a bonding agent. Laminating process laminating is the process through wh laminating process. Laminating machinery can be classified according to the type of bonding agent used to produce the laminates.

Impossible to trap air bubbles. Another lamination process uses a lamination press after materials are combined in a thicker structure than film. The hot melt process is used for high speed lamination since there is no need for a drying stage. For example a foil and paper substrate lamination may be accomplished through a wet bonding process.

No drying is required. It is commonly used to produce a paper aluminum foil laminate that is widely used in flexible packaging. Wet bond lamination is a laminating process used to laminate two substrates one of which is porous such as paper. Where the bonding agent is still in a liquid state when the webs are joined together.

Lamination is the technique process of manufacturing a material in multiple layers so that the composite material achieves improved strength stability sound insulation appearance or other properties from the use of the differing materials such as plastic a laminate is a permanently assembled object created using heat pressure welding or gluing. Water is the source of heat and therefore eliminates the need for a hot roll laminating machine. Drawing 1 illustrates the concept of the wet lamination method described. Cold foil printing also known as cold foil stamping is a modern method of printing metallic foil on a substrate in order to enhance the aesthetic of the final product cold foil printing can be done two ways.

The older dry lamination process common in the offset printing industry or the newer more versatile wet lamination process which is dominant in the flexo label industry. The wet lamination process can be used for the cost effective manufacture of components in simple shapes.
