Within the delivery of equipment for the restoring workshop room of Cieszyn’s Historical Library, a new roll laminator was purchased in September 2008.
The unit is used for heat-fusing of R laminate films, i.e. acid-free protective tissues, on one side or both sides of treated paper sheets. The tissue laminate is lined with heat curing acrylic adhesive on one side and contains alkali reserve based on magnesium carbonate. Tissue pH – 9,6. The magnesium carbonate is used to neutralize the acid formed in old paper, which may be carried over to the adhesive layer. Additionally, lamination may provide protection against further mechanical damage or even reconstruction of disintegrated parts of paper sheets. It should be emphasized that the process is fully reversible and the removed plastic laminate does not leave any lamination marks on the treated paper.
