Plan folders

Designs for flat items

Plan folders

This design is used for large, flat items, such as artworks and posters. We use our 300 GSM card to create these folders; the lightweight but robust material means that your items are protected against agents of deterioration without adding excess bulk.

How to measure for plan folders

The design includes wings to prevent items from slipping out, and a gummed Tyvek tape hinge, which does not remain sticky when dry, so it will not adhere to your objects.

Our folders use gummed Tyvek tape around all edges to provide a smooth surface for your items.

Our plan folders do not come with stiffener layers except by request. Please include in the notes if you require an additional layer in the base made from Conservation by Design's flute board, glued in with EVA. This added strength makes this folder ideal for holding a greater number of flat plans and reduces bowing of the folder on transport.
