Questions about this item

What size documents will the 8.75 x 11.5 inch open side format accept without folding?

The open side measures 8.75 by 11.5 inches, so flat sheets up to that width and height slide in directly; the booklet style opens on the long edge for easy insertion.

How does the 28 lb sulphite weight and vellum finish affect printer feeding and ink holdout?

At 28 lb the stock is stiff enough for reliable laser and inkjet feeding, while the vellum finish gives good ink holdout without feathering on either technology.

What sealing method is used and does the side seam construction allow flat stacking after sealing?

A remoistening gum on the flap seals with moisture, and the two side seams underneath keep the envelope lying flat for neat stacking in trays or boxes.
