Common questions
How do Ship-Lite® envelopes compare to standard kraft paper envelopes in durability?
Ship-Lite® envelopes are six times stronger than traditional paper envelopes due to their reinforced construction with mesh screen poly fibers. This tear and puncture resistance reduces damage claims, decreases product loss, and improves customer satisfaction while maintaining competitive shipping costs.
Are these envelopes compliant with major shipping carrier requirements?
Yes. The 26 lb. reinforced paper construction and self-seal closure meet standard carrier specifications for flat-rate and priority mail categories. The moisture-resistant properties ensure contents remain protected during multi-leg shipping routes and varying weather conditions.
What is the self-seal closure, and how does it compare to tape?
The integrated self-seal closure (press-and-seal design) eliminates the need for additional tape, reducing assembly time by up to 30% and lowering per-unit packaging costs. Simply press the adhesive strip to create a tamper-evident seal that meets USPS and carrier standards.
Can I order partial cases or bulk quantities for volume discounts?
