Common questions
How much stronger are Ship-Lite® envelopes compared to standard paper mailers?
Ship-Lite® envelopes are six times stronger than traditional paper envelopes due to reinforced mesh screen poly fiber construction. This durability significantly reduces in-transit damage, tear-open incidents, and associated replacement costs.
Do these envelopes require tape or additional sealing supplies?
No. The self-seal Redi-Strip closure eliminates the need for tape, glue, or adhesive. Simply press and seal for consistent, tamper-evident closure that saves labor time and material costs.
Are 10 x 13" Ship-Lite® envelopes compliant with USPS and carrier shipping standards?
Yes. The 10 x 13" flat format meets USPS, UPS, and FedEx size and weight specifications for expedited and standard ground shipping, ensuring no surcharges or delivery delays.
What protection does the moisture-resistant design provide?
The reinforced material with poly fiber mesh resists moisture and humidity, protecting document integrity and product condition during storage and transport. Ideal for temperature-variable warehousing and humid shipping environments.
