Why clothing brands ship in poly mailers

Most apparel orders do not need a box. A folded shirt or pair of leggings travels well in a flexible mailer, and the low weight and slim profile help keep shipping costs down. Custom poly mailers are made from co-extruded polyethylene film, often with a gray or black inner layer that keeps contents private, and a peel-and-seal adhesive strip that shows if the mailer has been opened.

Choose the size from your most common order rather than your largest, and add a second size for bulkier items. Matte films look modern and photograph well for unboxing posts, while gloss gives bright colors more punch. Custom poly mailers for clothing brands often add a second adhesive strip so customers can reuse the mailer for returns. Ask about recycled-content films if that matters to your customers, and note that recycling access for film varies by area.

The mailer travels through sorting centers and doorsteps, so treat it like a small billboard. A bold logo or pattern on the front, a short message on the back, and space left clear for the shipping label work well. Custom poly mailers with logo wholesale orders can share one design across sizes. For brands shipping across the USA and Canada, keep any required return address area easy to find.

Printing

FAQ

Custom Poly Mailers: questions answered

Still unsure? Ask a packaging specialist.

Are custom poly mailers good for shipping clothing?

Yes. Folded clothing is light and does not crush, so a flexible mailer protects it from dirt and moisture while keeping weight and size low. For fragile or structured items, such as shoes or boxed gifts, a mailer box or padded mailer is safer.

Can I get custom poly mailers with my logo?

Yes. We print your logo, pattern or full design on the mailer in one or several colors. The digital proof shows the artwork, the seal flap and the area kept clear for shipping labels, so you can check everything before production.

What size poly mailer do I need?

Fold your most common order the way you pack it, measure it, and add a little room for the seal and thickness. Send those measurements and we suggest a size. Many brands use two sizes to cover single items and bundles.

Can poly mailers be reused for returns?

Yes, if you add a second adhesive strip and a tear line. The customer opens the mailer along the tear line, places the return inside and seals it with the second strip, which makes exchanges simpler for apparel brands.

How do I get pricing for custom poly mailers wholesale?

Send the sizes, film color, print design, closure type and quantity per size through the quote form. A specialist replies with pricing for each option, and you approve a digital proof of every size before production begins.
