Folabase H45

The classic, best-practice self-adhesive underpacking foil   – discontinued –

The self-adhesive polyester underpacking foils of the Folabase range are characterised by high resistance to swelling in the presence of damping solution and washing agents. They are used to adapt the cylinder circumference and printing length on sheet-fed and web presses. The self-adhesive versions support automation, particularly on presses with automatic plate changers, and simplify subsequent handling.

The microgrooves created by fine lines in the adhesive surface simplify mounting on the cylinder and, if necessary, also facilitate re-mounting during application. The adhesive coating is protected by release paper. Folabase adhesive systems are characterised by high thermal stability up to 60 °C.

In contrast to paper-based underpacking sheets, the tear-resistant, dimensionally stable polyester does not suffer any reduction in thickness when exposed to excessive pressures. Since they contain no PVC, used foils can be disposed of without difficulty.
