Q: What makes these bubble mailers more environmentally friendly than standard options?
A: Our mailers are made with 50% recycled content (post-consumer and post-industrial recycled components), are completely recyclable, use Australian-made materials with local sourcing, and support multiple reuses. Our medium black mailers are the sustainable choice compared traditional plastic shipping bags.

Q: How do tamper-evident seals work for secure shipping?
A: The adhesive seal requires significant force to breach, typically requiring scissors to open cleanly. Any forced entry attempts will leave visible damage, providing clear evidence of package tampering.

Q: Can these mailers be reused?
A: Absolutely! The strong triple-layer design and premium materials support repeated usage. Although the security seal can only be used once, standard packaging tape can be used as an alternative for return shipments.
