Common questions
How does Tyvek® material compare to kraft paper envelopes?
Tyvek® is ten times stronger than paper, it resists tears, punctures, and moisture penetration while remaining lightweight. This reduces damage claims and returns, lowering your total cost of ownership despite slightly higher per-unit pricing.
Are these envelopes suitable for USPS, UPS, and FedEx shipping?
Yes. Tyvek® envelopes meet all major carrier standards for First Class Mail, Priority Mail, UPS Ground, and FedEx services. They also comply with postal regulations for mailability and hazmat guidelines when required.
Can the expandable design fit items larger than 1.5 inches?
The envelope expands up to 1.5 inches to accommodate bulky contents like documents, disks, or small components. Items exceeding this depth require a larger envelope size to ensure proper sealing and compliance.
Is the self-seal adhesive reliable, or will I need additional tape?
The Redi-Strip self-seal closure is engineered for single-use security and holds reliably for standard shipping environments. No additional tape is required when sealed properly, reducing labor time by 15-20% per shipment compared to tape-sealed alternatives.
