The Renz Aquarelle Colour Thermal Binding Covers are made of a coloured linen structured cardboard (240 gr/m] and the front with a matte transparent plastic.
All covers come with a strip of glue pre-attached to the spine and also pre-scored hinges both in front and back of the cover. As a rule of thumb, 10 sheets of 80 gr/m2 paper can be bound for each mm of spine width.
A4 Heat resistant Polyester Fastback covers are specially formulated to not buckle or bend when bound using the Fastback thermal binding machines. The A4 Clear Polyester covers are supplied tissue interleaved between each sheet to prevent scratching that cannot be avoided with clear PVC covers. The anti static tissue interleave also makes them very easy to use during application
