Common questions
Do these envelopes require water or moisture to seal?
No. Simply peel back the tear strip to expose the self-sealing adhesive, then press the flap closed. This eliminates water applicators, sponges, and the mess associated with traditional gummed envelopes.
How long does the adhesive stay fresh in storage?
The integrated tear strip keeps the adhesive protected from dust, moisture, and air exposure, maintaining seal quality for extended shelf life. Store in a cool, dry environment for optimal performance.
Will these envelopes meet shipping compliance and carrier requirements?
Yes. The 28 lb. kraft paper stock meets standard mailroom and carrier specifications for flat mail and small parcel sealing. Adhesive creates a secure, tamper-evident seal compliant with USPS, UPS, and FedEx standards.
How many envelopes can one employee seal per hour?
With no water or applicator setup required, employees can seal 300-400+ envelopes per hour, compared to 150-200 with traditional gummed envelopes. This translates to faster mailroom throughput and reduced labor costs per piece.
