Common questions
Will these mailers work with UPS, FedEx, and USPS?
Yes. These #4 self-seal bubble mailers meet standard carrier requirements for all major shipping platforms including USPS, UPS, and FedEx. The tamper-evident peel-and-stick closure is carrier-approved and provides proof of security.
How much shock protection does the 3/16" bubble lining provide?
The 3/16" bubble lining offers reliable cushioning for lightweight to medium-weight fragile items such as electronics, cosmetics, and glassware. For heavier or extremely fragile items, consider layering with additional void fill or upgrading to mailers with thicker bubble.
Can I apply custom labels to these kraft mailers?
Absolutely. The recycled kraft paper exterior accepts shipping labels, printed branding, and custom stickers without adhesion issues. The neutral kraft tone provides professional appearance and excellent label contrast.
How many items per case, and what's the coverage per roll equivalent?
Each case contains 100 mailers. At standard packing volumes of 50-100 shipments per day, one case provides 1-2 days of supply for mid-sized e-commerce operations, making bulk ordering cost-effective for recurring shipping needs.
