Kraft Clasp Envelope 10 x 13 32Lb 100/Box

These envelopes use heavyweight Kraft stock measuring 10 by 13 inches with a 32 lb basis weight. The reinforced eyelet and two-prong metal clasp allow repeated opening and closing without tearing. A gummed flap provides a secure seal when moisture is applied. The box contains 100 light brown envelopes suitable for office filing and shipping.

Practical limits of clasp closure and gummed seal

The metal clasp is designed for manual fastening and may not withstand automated sorting equipment. Gummed adhesive requires moisture to activate and can lose tack in very dry or humid conditions. Heavyweight 32 lb stock adds rigidity but increases shipment weight compared to lighter paper grades. Users needing tamper-evident security or machine-processable mail should consider alternative closure methods.

Questions about this item

Should I pick the 10 x 13 size or a smaller envelope for my documents?

The 10 x 13 envelope fits letter-size pages flat without folding, while smaller sizes would require creasing documents.

How does the 32 lb Kraft stock perform when the envelope is fully loaded?

The heavyweight 32 lb Kraft material resists rips and tears even when stuffed with up to 100 sheets, and the reinforced eyelet with two-prong clasp holds securely through repeated opening and closing.
