Wet Bond Lamination Process

Wet lamination is best for the production of aluminum foil or paper laminate where the material is also flexible.

Wet bond lamination process. Hot melt lamination uses hot melt adhesives instead of solvent or water based adhesives laminating and coating. Dry bonding wet bonding uv eb curing and hot melt adhesion processes table 4 2 6. Laminating machinery can be classified according to the type of bonding agent used to produce the laminates. The adhesive lamination process utilizes adhesive to bond two substrates.

This process was deemed inconvenient and by 1948 progress was made in dry lamination using polyvinyl acetate plasticized with dibutyl phthalate. Wet bonding refers to any process where a liquid adhesive is applied to a substrate that is then immediately combined with a second ply to create a laminate. The process differentiation is defined by the type of adhesive used and how the adhesive is applied and converted. 10 4 3 hot melt lamination.

Wet bond lamination is a laminating process used to laminate two substrates one of which is porous such as paper. It is commonly used to produce a paper aluminum foil laminate that is widely used in flexible packaging. This practice strengthens the bond of the laminate as well. Where the bonding agent is still in a liquid state when the webs are joined together.

Shim in joining textiles 2013. In the 1930s a wet lamination process with the use of solvents was used to bond shirt collars a woven fabric with cellulose acetate. China water based wet lamination adhesive catalog of waterbrone acrylic dispersion for cold laminating adhesive glue waterborne acrylic laminating adhesive wet glue for bopp to paper provided by china manufacturer anhui elite industrial co ltd page1. For example a foil and paper substrate lamination may be accomplished through a wet bonding process.

One of the first applications was laminating light gauge aluminum foil to tissue using either casein or sodium silicate adhesives. These processes are classified under four categories.
