Product Identity

These Western States open-end mailer envelopes measure 11 x 13.5 inches and come in a box of 100. They are built from 100% recycled board with a pressure-sensitive seal for quick closure. The design suits offices, schools and shippers sending flat documents, photos or certificates that must not be bent.

Thermals Noise Power

As paper envelopes, these items produce no heat, noise or electrical draw during handling or storage. The 28 lb board weight provides rigidity without adding bulk to a shipment. No power source or cooling is involved at any stage of use.

Sustained Load Behaviour

Under continuous mailing cycles the envelopes maintain their structural integrity and the adhesive seal remains reliable across the full box of 100. The centre seam and extended flap resist tearing when packed to capacity. They are not suited for bulky or heavy objects that exceed the flat mailer format.

Questions about this item

How do you seal the pressure-sensitive flap without trapping air bubbles?

Press firmly along the entire adhesive strip from one end to the other, smoothing the flap onto the envelope body so the seal bonds evenly across the 11 by 13.5 inch surface.

When does the recycled board start to weaken if the envelopes are stored in a humid office?

The 28 lb board resists moisture for typical indoor conditions; replace any envelopes that feel limp or show fibre separation before loading them with documents.

At what weight does the centre seam risk splitting during transit?

The 28 lb recycled board and centre seam construction are rated for standard document loads up to the 100-count box weight; heavier inserts should use a reinforced mailer.
