Heavy-duty clasp envelopes

These are heavy-duty clasp envelopes in a 28 lb kraft stock. The open-end style and reinforced metal clasps provide secure closure for documents. Rounded, plated clasps resist rust during storage or transit. Each box contains 100 envelopes.

High-volume mailing and filing

Offices that regularly send or archive bulky paperwork will value the deep gumming and large flap. The reinforced construction protects contents through handling and stacking. Buyers who need self-seal or peel-and-seal closures should consider other styles. Those requiring lighter-weight envelopes for everyday correspondence may prefer a lower basis weight.

28 lb basis weight

The 28 lb paper weight determines how much bulk and rigidity each envelope adds to a mailing. It also affects postage cost and the feel of the package in hand. Match this specification to your shipping requirements and handling expectations before ordering.

Questions about this item

Will the 28 lb Kraft paper hold up if the envelopes sit in a hot warehouse all day?

The 28 lb Kraft stock is heavy-duty and the metal clasp is plated for rust-resistance, so heat and humidity will not weaken the seal or corrode the clasp.

Do I need any special sealer or moistener to close the 100 envelopes in this box?

No. The flaps have deep gumming that activates with a lick or a damp sponge, and the reinforced metal clasp provides a second mechanical closure without extra tools.

Can I run these 6x9 envelopes through an older laser printer that only takes standard letter stock?

These are open-end clasp envelopes, not printer-ready sheets, so they are meant for hand-addressing or labelling rather than feeding through a legacy laser tray.
