FAQ
Questions from buyers
How are flat poly mailers different from bubble mailers?
Flat poly mailers have no cushioning layer. They are thinner and lighter, making them ideal for non-fragile items where padding isn't needed. Bubble mailers provide interior cushioning and are better for items that could be damaged by bending or impact.
What items are best suited for flat poly mailers?
Flat poly mailers work best for soft, flexible, or non-fragile items such as:
- Clothing and apparel
- Accessories (scarves, hats, belts)
- Soft toys
- Fabric and textiles
- Documents and catalogs
- Stickers, posters, and prints (when rigid backing is not required)
- Pharmaceutical products
Are these approved for USPS, UPS, and FedEx?
Yes. Flat poly mailers are accepted by all major carriers. Verify your carrier's weight and size limits before shipping.
Can I reuse a flat poly mailer?
No. The peel-and-seal adhesive is a one-time closure. Once sealed, the mailer cannot be resealed cleanly. Single-use is recommended for all outgoing shipments.
Are these eco-friendly?
Yes, mailers contain 50% recycled content. They are also approved by NexTrex and can be dropped off at grocery store recycling bins, reducing landfill waste.
