Common questions
How does Redi-Seal technology work and how much time does it save?
Redi-Seal envelopes feature a pressure-sensitive adhesive strip pre-applied to the flap. Simply fold down the flap and press firmly to seal, no water, sponges, or moisture required. Users typically save 3-5 seconds per envelope compared to traditional gummed sealing, translating to 25-40 minutes saved per 500-envelope case in high-volume operations.
Are these envelopes compliant with USPS and shipping standards?
Yes. These 9 1/2 x 12 1/2" Kraft envelopes meet USPS size requirements for standard mail and flat-rate shipping. The durable 28 lb. paper stock provides adequate protection for documents and light materials during transit, and the secure Redi-Seal closure prevents accidental opening.
What makes 28 lb. Kraft paper better than lighter weights?
28 lb. Kraft paper offers durability, puncture resistance, and tear strength compared to lighter 24 lb. alternatives. This heavier stock protects contents during sorting, handling, and transport while projecting a more professional appearance, critical for business correspondence, invoices, and formal documents.
Can bulk orders be customized or do you offer volume pricing?
Yes. Packrift offers competitive volume pricing on cases of 500 and larger quantities. Contact our sales team to discuss bulk orders, custom printing options, and volume-based discounts for ongoing mailroom supply contracts.
