Common questions
Are these mailers suitable for fragile items?
These poly mailers provide excellent protection against moisture, punctures, and tearing, making them ideal for apparel, soft goods, and non-fragile items. For breakable products, we recommend adding interior padding or selecting rigid box alternatives.
Can I print directly on these mailers?
Yes. The white outer surface accepts labels, stamps, and ink applications well, allowing you to add branding, tracking info, or shipping labels. The silver interior also accommodates printed messaging.
How secure is the self-seal closure?
The integrated self-seal strip provides a tamper-evident, secure closure with high-strength seams that keep contents intact even if the mailer is overpacked. Once sealed, it creates a permanent bond that won't open during transit.
What's the shelf life of these mailers, and do they store well?
Polyethylene mailers have no expiration date and maintain integrity indefinitely when stored in cool, dry conditions away from direct sunlight. The flat-pack design makes them space-efficient for warehouse storage.
