Envelopes with New Improved Side Seam Design
Ivory coloured envelopes are excellent acid-free and lignin-free storage device for all types of documents, pamphlets, clippings, etc. Buffered with approximately 3% calcium carbonate. Each is constructed using a neutral pH adhesive and includes an ungummed flap to help out dust and light. We have eliminated the center seam which could mar the contents if too much pressure or weight is applied. Instead we have incorporated two side seams that are not only safer, but provide more even stacking and filing in large groups. No adhesive on flap. Price per 100 envelopes.
