Before You Order

Custom Printed Poly Mailer FAQ

Practical answers on choosing the structure, avoiding common problems, and confirming the right specification for your product.

Where should graphics stop near seams and the closure?

Supply the bag dieline showing seams, folds, flap and shipping-label area. Keep essential wording out of distorted or sealed regions and review a filled mockup. Full coverage needs approval on the complete parcel because folds can obscure artwork that looks clear when flat.

Technical references
How can the shipping label coexist with full-color artwork?

Reserve a practical, low-interference label area and test its adhesive on the final print finish. Place barcodes on a smooth part of the filled parcel with clear margins. Check readability after handling so branding does not compromise dispatch scanning.

Technical references
What should we check for heavy print coverage?

Evaluate ink rubbing, blocking during storage and appearance at folds using production-equivalent printed samples. Share storage and packing conditions as well as artwork. Approval should include a filled bag and normal label application, especially where operators rub or bend the surface.

Technical references
Which specification prevents inconsistent repeat orders?

Record the film construction, bag dimensions, flap geometry, approved color reference and print position with the signed sample. Identify any critical shipping-label zone. Review changes to film or closure separately because a matching graphic does not ensure identical loading and sealing behavior.
