FAQ

Q: Is this mailer suitable for Amazon FBA shipments? A: Yes — our white corrugated mailers meet Amazon FBA packaging requirements when properly sized to the product. Key compliance points: the self-seal adhesive eliminates loose tape that can jam automated sortation equipment; the tear strip provides frustration-free opening that reduces customer returns due to packaging difficulty; and the box passes the 3-foot drop test required for items under 50 lbs. We recommend adding Amazon’s frustration-free packaging certification to your listing after using this mailer.

Q: What’s the difference between B-flute and E-flute, and how do I choose? A: B-flute (3mm thick) provides higher crush resistance and is better for items weighing 500g–5kg. It has 47 flutes per linear foot and excellent stacking strength. E-flute (1.5mm thick) is thinner, lighter (saves on dimensional weight shipping charges), and provides a smoother printing surface for high-quality graphics. It’s ideal for items under 500g like cosmetics, accessories, and small electronics. For very fragile items, we can also offer F-flute (0.8mm) which is nearly as thin as solid board but with cushioning properties.

Q: How does the self-seal adhesive perform in cold or hot climates? A: Our hot-melt pressure-sensitive adhesive is formulated to bond reliably from -20°C to 60°C. For extreme cold-chain shipping (frozen foods, pharmaceuticals), we can upgrade to a specialized cold-temperature adhesive that bonds at temperatures as low as -40°C. For hot-climate shipping (Middle East, Southeast Asia), the standard formulation already maintains bond integrity up to 65°C. We recommend specifying your shipping climate during the quotation stage.

Q: Can the interior be printed with a brand pattern or message for unboxing? A: Yes — we offer interior printing on the white kraft liner. Full-color CMYK offset can transform the inside of the mailer into a branded experience with patterns, social media handles, discount codes for repeat purchases, or assembly instructions. Interior printing adds approximately 2 days to production time and is available on orders of 3,000 units or more. This is a proven strategy for increasing social media unboxing shares and repeat purchase rates.

How the White Corrugated Mailer Compares for E-Commerce Shipping

When the White Corrugated Mailer Wins: For DTC e-commerce brands shipping cosmetics, apparel, or accessories where the packaging IS the brand experience — the white kraft exterior prints full-color CMYK brand graphics that a poly mailer can’t match, while the self-seal + tear strip eliminates the packaging tape that 37% of consumers cite as their top unboxing frustration (DHL 2024 e-commerce packaging survey). The B-flute crush protection means your product arrives in sellable condition — reducing returns and negative reviews.
