Quality Park No. 10 Single Window Security Tint Envelopes: reflex blue security tint protects contents

Security tint keeps client details private even when envelopes are held to light.

Product Overview:

You need mail that does its job without drama. These No. 10 single window envelopes pair a reflex blue security tint with a self-adhesive commercial flap, so sensitive documents stay unreadable and mailing goes faster. They work in automated inserters because of a traditional diagonal seam, come in sturdy twenty-four-pound white wove stock, and the window is positioned to align reliably with addresses. If you handle invoices, statements or client notices, this box of five hundred cuts down fiddling and rework. Picture a quieter mailroom and the relief of knowing details stay private when the light hits the paper.

Key Features:

• Security Tint: Reflex blue interior pattern blocks readable details even when you hold an envelope to the light.
• Window Size & Placement: Single window is one-and-one-eighth-inch by four-and-a-half-inches, set to align addresses reliably in inserters.
• Closure: Moisture-seal commercial flap gives a clean, fast seal so envelopes ship without extra tape or fuss.
• Paper Weight: Twenty-four-pound white wove stock feels substantial and feeds smoothly through folding and inserting equipment.
• Seam & Automation Compatibility: Traditional diagonal seam is compatible with automated inserting and folding equipment, reducing jams and delays.
