Where the bonding agent is still in a liquid state when the webs are joined together.
Wet lamination process.
The laminate then passes through the chilled nip of the combiner roll cooling the plastic layer which solidifies.
Laminating machinery can be classified according to the type of bonding agent used to produce the laminates.
For example a foil and paper substrate lamination may be accomplished through a wet bonding process.
Particles and other surface contaminants are washed away by water.
Once the wet bonding process is applied to each substrate the two substrates will then be combined prior to passing through an.
The large proportion of manual production requires well trained specialists and careful quality control.
As an example azdel a glass reinforced thermoplastic composite made with continuous glass mat is produced using an extrusion lamination operation film continuous random orientation glass mat and molten resin are combined in a lamination process using a sandvik double belted.
Wet lamination showed to have the following advantages.
Water is the source of heat and therefore eliminates the need for a hot roll laminating machine.
When only the two layers are involved the process is known as extrusion coating.
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.
Wet bond lamination is a laminating process used to laminate two substrates one of which is porous such as paper.
Another lamination process uses a lamination press after materials are combined in a thicker structure than film.
No drying is required.
The wet lamination process can be used for the cost effective manufacture of components in simple shapes.
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 hot melt process is used for high speed lamination since there is no need for a drying stage.
Laminating is the process through which two or more flexible packaging webs are joined together using a bonding agent.
The substrates making up the webs may consist of films papers or aluminum foils.
It is commonly used to produce a paper aluminum foil laminate that is widely used in flexible packaging.
Laminating process laminating is the process through wh laminating process.
