Rare Document Binders with Polyester Inserts – #MRDP-7-9-10-11-12-15-13

These are ideal for storing rare pamphlets, magazines, folded maps or other items which are up to 1/4″ thick. They feature .060 board backs and .004 polyester L-seals held in place using archival polyester-based tape. The L-seals offer the advantage of easy insertion, with the opening facing toward the spine of the binder for secure storage. Polyester L-seals offer two further advantages over traditional binders with archival paper envelopes mounted inside. In the first place, crystal-clear polyester allows immediate visual recognition of the item inside; furthermore, unlike envelopes with flaps and center seams, the L-seal places no pressure points against the material stored within it. Offered in your choice of Lig-free I or MicroChamber. Bear in mind that items should be somewhat smaller than the insert size indicated below to accommodate the thickness of the item while allowing the binder to close completely.
