Common questions
What does ECT-32-B rating mean for my shipping needs?
ECT-32-B indicates edge crush test strength of 32 pounds per inch, providing reliable crush resistance for small item shipments. This rating ensures consistent protection across temperature and humidity variations, critical for compliance-sensitive and fragile goods.
How much postage can I save with these lightweight mailers?
Kraft corrugated mailers significantly reduce dimensional weight charges compared to rigid boxes. The fold-flat design minimizes inbound freight costs, and lighter overall weight reduces per-unit postage on parcel carrier networks like USPS, UPS, and FedEx.
Do these mailers require tape or additional sealing materials?
No. The one-piece fold-and-tuck design seals securely without tape, glue, or staples, eliminating material costs and labor time per mailer. Assembly takes seconds, boosting fulfillment throughput in high-volume operations.
What is the environmental impact of ordering in bulk bundles of 50?
These kraft corrugated mailers are 100% recyclable and made from renewable kraft fiber. Ordering in bundles of 50 reduces packaging waste per unit and supports sustainable supply chain practices while lowering per-box acquisition cost.
