Wet Bond Lamination Process

Once the wet bonding process is applied to each substrate the two substrates will then be combined prior to passing through an.

Wet bond lamination process.

In this process the combining agents are kept in liquid form when substrates are needed to be combined. In the 1930s a wet lamination process with the use of solvents was used to bond shirt collars a woven fabric with cellulose acetate. Flexible future 2002 they are 100 solid materials that melt to the liquid phase when they are heated to the temperature ranges of 80 200 c and solidify to form bonding when they cool glawe et al 2003. Hot melt lamination uses hot melt adhesives instead of solvent or water based adhesives laminating and coating.

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. Dry bonding wet bonding uv eb curing and hot melt adhesion processes table 4 2 6. It is commonly used to produce a paper aluminum foil laminate that is widely used in flexible packaging. Wet lamination is best for the production of aluminum foil or paper laminate where the material is also flexible.

10 4 3 hot melt lamination. Where the bonding agent is still in a liquid state when the webs are joined together. This process was deemed inconvenient and by 1948 progress was made in dry lamination using polyvinyl acetate plasticized with dibutyl phthalate. Wet bond lamination is a laminating process used to laminate two substrates one of which is porous such as paper.

One of the first applications was laminating light gauge aluminum foil to tissue using either casein or sodium silicate adhesives. Shim in joining textiles 2013. These processes are classified under four categories. This practice strengthens the bond of the laminate as well.

The adhesive lamination process utilizes adhesive to bond two substrates. The process differentiation is defined by the type of adhesive used and how the adhesive is applied and converted.
