White sulphite catalog envelopes

These open end envelopes measure 11.5 by 14.5 inches and use 28 lb white sulphite paper with 92 percent brightness. The centre seam construction and vellum finish suit high volume mailing rooms that need a professional appearance. A remoistening seal keeps contents secure during transit. Condition is new.

Box of five hundred with SFI certification

Each carton contains 500 envelopes weighing 32.5 lbs total, certified by the Sustainable Forestry Initiative for responsible sourcing. The flap down design feeds cleanly through inserters and hand stuffing alike. No window means full face printing or labelling is possible. The bulk pack reduces reorder frequency for busy departments.

Handles standard catalogs and large documents

The generous dimensions accommodate unfolded brochures, reports and catalogues up to the envelope size. Paper weight provides stiffness without excessive bulk for postage calculations. Heavy parcels or rigid items that exceed the flat profile will not fit. Users needing padded protection or expansion gussets should choose a different style.

Questions about this item

Will the remoistening seal on these 11.5 x 14.5 inch envelopes need replacement after long storage?

The remoistening seal is integral to the flap and activates with moisture each time you close an envelope; no separate replacement part exists.

What limit appears first when feeding 500 envelopes through a high-volume inserter all day?

The 28# Western Sulphite paper with vellum finish and centre seam construction determines jam resistance and feed reliability under continuous loading.

How much heat or noise does a box of 500 envelopes add to a mailroom running all day?

The envelopes themselves generate no heat or noise; only the inserting or sealing equipment contributes to the environment.
