Common questions
Are Ship-Lite® envelopes stronger than standard paper mailers?
Yes. Ship-Lite® envelopes are six times stronger than traditional paper envelopes due to their reinforced 26 lb. paper construction combined with embedded mesh screen poly fibers. This durability protects contents during transit while keeping costs significantly lower than bubble mailers.
Do these envelopes meet shipping carrier requirements?
Absolutely. The self-seal Redi-Strip closure and reinforced construction comply with USPS, UPS, and FedEx shipping standards. No additional tape or fasteners are required, simplifying your fulfillment process and reducing material expenses.
Will moisture damage contents inside these envelopes?
No. The moisture-resistant reinforced paper provides a protective barrier against humidity and light water exposure. This makes Ship-Lite® envelopes ideal for shipping documents, photos, and sensitive materials in variable weather conditions.
How many envelopes come in each case and what's the per-unit cost benefit?
Each case contains 100 ready-to-use flat Ship-Lite® envelopes. Bulk purchasing eliminates assembly time, reduces per-unit shipping costs through flat storage, and provides consistent inventory for high-volume fulfillment operations while maintaining professional presentation quality.
