FAQ
Q: What’s the difference between tear strip and perforated opening?
A: Tear strip uses an embedded plastic or paper ribbon that cleanly separates the box in one pull. Perforated opening uses pre-cut dotted lines. Tear strips provide a cleaner edge and more premium unboxing feel — recommended for DTC brands.
Q: Can you print inside the mailer box?
A: Yes. We offer full inside printing on the white-top liner — brand messaging, social media handles, discount codes, or return instructions can be printed inside for a complete branded-experience mailer.
Q: What’s the minimum order for custom sizes?
A: MOQ is 500 units for standard BC-flute construction. For custom die-cut shapes, MOQ is 1,000 units. We offer stock sizes with instant availability for smaller runs (100-300 units).
Q: Are these mailers recyclable?
A: Yes. FSC-certified kraft liners with water-based inks and removable tear strips are fully recyclable in standard curbside programs. We also offer 100% post-consumer recycled (PCR) liner options.
Q: How do you test for transit durability?
A: All mailer designs undergo ISTA 3A testing: 10-drop sequence from 760mm, random vibration (truck+air profile), and top-load compression to 200kg. Test reports provided with production lots.
