Mailers & Envelopes for E-Commerce and Business Shipping
Poly mailers, bubble mailers, kraft mailers, bookfold mailers, and envelopes — 700+ SKUs for every shipping application.
The right mailer protects your products and creates a great unboxing experience for your customers. Material Handling USA carries a complete line of mailers for every shipping need, from lightweight poly mailers to rigid fiberboard mailers for documents and photos.
Poly mailers are the most popular choice for e-commerce apparel, soft goods, and non-fragile items. They are waterproof, tear-resistant, and significantly lighter than boxes — reducing shipping costs. Co-extruded poly mailers offer enhanced strength compared to standard coextruded film.
Padded bubble mailers combine the flexibility of a poly envelope with the cushioning of bubble wrap, making them ideal for small electronics, jewelry, cosmetics, and books. Kraft bubble mailers are available for a more premium look.
For documents, photos, and rigid items, our bookfold mailers and fiberboard mailers provide rigid protection without the bulk of a full carton. Die-cut mailers with side-loading and self-locking designs streamline packing operations for high-volume fulfillment.

Frequently Asked Questions
What size poly mailer should I use for a t-shirt?
A single folded t-shirt fits in a 10×13" poly mailer. For multiple shirts or hoodies, use 12×15.5" or 14.5×19". For jeans or larger clothing items, use 14.5×19" or 19×24". Always fold items neatly to minimize bulk.
Are poly mailers waterproof?
Yes — co-extruded poly mailers are completely waterproof and resistant to tearing, puncture, and moisture. They are not tamper-evident on their own, though self-seal peel-and-seal closures make them tamper-resistant.
Can I print my logo on poly mailers?
Yes — custom printed poly mailers are available with your logo, brand colors, and messaging. Minimum order quantities typically start at 500–1,000 pieces. Contact us at (800) 326-4403 for custom printing quotes.
What is the weight limit for poly mailers?
Standard poly mailers are rated for items up to approximately 5 lbs. Heavy-duty co-extruded mailers can handle items up to 15–20 lbs. For heavier shipments, use corrugated boxes with proper void fill instead.
