Common questions
What is the bubble cell size and how much protection does it provide?
These mailers feature a 3/16" bubble cell height that provides excellent shock absorption for lightweight to moderately fragile items. The slip-bubble design allows products to shift slightly within the bubble layer, distributing impact energy and protecting contents during transit.
Is the self-seal closure strong enough for USPS, UPS, and FedEx shipping?
Yes. The peel-and-stick adhesive creates a secure, tamper-evident seal that meets carrier requirements. The closure is reusable if needed and doesn't require additional tape, reducing labor costs and packaging material waste.
How much coverage per roll do I get, and what's the cost per unit?
You receive 500 mailers per case, delivering substantial coverage for mid-sized e-commerce operations. Ordering by the case ensures consistent pricing and reduces per-unit costs compared to smaller quantities.
Can I use these mailers for items larger than 8" x 4"?
The 8" x 4" (#000) size is optimized for small, compact products like jewelry, small electronics, and cosmetics. For larger items, consider larger sizes in the bubble mailer line. The interior space accommodates snug fitting to maximize protection and minimize shipping weight.
