Common questions
What size items fit in a 4" x 8" bubble mailer?
This size accommodates small to medium items such as jewelry, phone accessories, cosmetics, small electronics, documents, and gift items. The flexible poly material allows slight overstuffing for soft goods without compromising the seal.
Is the peel-and-seal closure UPS/FedEx/USPS compliant?
Yes. The self-adhesive strip creates a secure, tamper-evident closure that meets carrier requirements for USPS, UPS, and FedEx shipping. The white exterior is compatible with printed labels and barcode scanning.
How much bubble coverage does the 3/16" lining provide?
The 3/16" bubble lining covers the interior surface, creating multiple cushioning layers that absorb impact and vibration. This thickness is ideal for fragile items requiring moderate protection during standard ground shipping.
What's the advantage of ordering a case of 500 vs. smaller packs?
A 500-count case offers the lowest per-unit cost and ideal for high-volume shippers, reducing reorder frequency and storage needs. For lower volumes, we also offer 25-pack quantities.
