What is Lamination
Lamination is the process of manufacturing a material in multiple layers, so that the combined physical and mechanical characteristics of each layer make for a stronger, more resilient composite material.
The earliest examples of lamination made use of natural adhesives such as beeswax, gums, tar and substances derived from animal bones. As technology progressed, we discovered the use of sealing wax as the first hot-melt adhesive. In the 1930s a wet lamination process (with the use of solvents) was used to bond shirt collars (a woven fabric) with cellulose acetate. This process was deemed inconvenient, and by 1948 progress was made in dry lamination using polyvinyl acetate plasticized with dibutyl phthalate.
