Common questions
Will the self-seal adhesive hold through rough handling and weather?
Yes. The adhesive strip is engineered to create a permanent, tamper-evident bond that withstands moisture, temperature changes, and carrier handling. Once sealed, the mailer cannot be opened without visible damage.
Is 2.5 mil thick enough to prevent punctures during shipping?
Absolutely. The 2.5 mil polyethylene provides excellent puncture resistance for standard e-commerce shipments. For high-value or fragile items, consider adding internal padding or using our 4 mil option for maximum durability.
Can I customize these mailers with my brand logo?
Yes. Packrift offers custom printing on orders of 5,000+ units. Contact our sales team for design templates, lead times, and pricing.
What products fit best in a 39" long mailer?
These mailers are ideal for rolled posters, blueprints, documents, scarves, leggings, and any elongated items up to 39" in length. The 8 1/2" width accommodates standard rolled sizes without crushing content.
