Custom Poly Mailer Bags Promotional Products.

Plain film for soft goods, a heavier gauge where a hard edge or a corner is the risk, and bubble lining for anything breakable. Custom poly mailers come in all three, and the table below sets out which contents take which.

Folded apparel absorbs the handling itself, so plain film does the job and keeps the cost down. A binder corner presses through thin film in a sorting machine, so that's where you want the heavier gauge. Thicker film stops a puncture but passes the impact straight through to the item, so breakable contents get bubble lining instead of more thickness. Personalized bubble mailers keep your print on the outer face and the cushioning on the inside.

Size the bag against the contents laid flat, plus clearance for the seal flap. The flap isn't usable space inside the bag, so a bag picked off how the item sits on a desk usually arrives one size too small.

Opaque film stops the contents showing through and gives your brand color a neutral background to print against, while clear or translucent film is right when the contents are the point. A permanent self-seal strip is the standard closure, and a second peel-and-seal strip lets the recipient close the same bag and send it back to you.

Your logo goes out on every parcel you send rather than once, and the whole shipment looks deliberate instead of thrown together. Kits for new hires mailed to home addresses, client welcome packs and closing gifts, conference materials sent ahead to a venue, sample and clinic packs, loaner hardware that goes out and comes back.

Cushioning on an apparel shipment buys you nothing, so plain film is the right call there and the cheaper one, and when that's the answer we'll say so. If the item needs structure, has to stack, or it's a gift where the unboxing is the moment, our custom mailer boxes cover that instead.

Bold, solid shapes are what print cleanly on poly film, and your logo sits inside the bag face, clear of the seal strip and the flap. The adhesive strip and the folded flap aren't print surface, so the print doesn't run right across the bag.

The same ink looks different on white, colored and metallic film, because the film color underneath it changes your brand color. White gives you a neutral background, so your brand color prints closest to your brand book. That's why we usually start you on white, and it isn't the expensive one either.

Hairlines and gradients break up on film, and a bubble-lined face dimples over the air pockets, so fine detail loses its edges there. A logo file that's low resolution, the kind that goes blurry when you enlarge a photo, prints with soft edges at bag size, while vector art stays sharp at any size.

Send us what you have. Any common logo file format is enough for the team to get going, and we check it and fix anything that needs it before your proof.

Decoration fit is the thing nobody can judge from a screen on this product, so a physical sample is worth asking for: printed color and how the film catches light only settle once the bag's in your hand. A digital proof still comes first, minimums start as low as 1 unit and vary by bag, and our team picks up your inquiry and puts it right if anything's off.

Still deciding? Start with a standard poly mailer sized to what you're shipping now, printed one color, centered. From there the two calls most buyers make are film weight (lighter for soft goods, heavier for anything handled more) and finish, matte or glossy, both narrowed with the filters above.
