How to use

Insert the document or flat item centrally into the carton mailing bag so edges are aligned and the content sits flat. If needed, add a thin protective layer such as tissue or a cardboard insert to fill gaps and prevent movement. Close the bag following the manufacturer's closure method (fold and seal or adhesive strip if present). Apply address labels and postage on the flat surface, ensuring any seams or seals are secure before dispatch.

Usage recommendations

For best results, use the ColomPac B5+ carton mailing bags for single-sheet documents, thin booklets and prints. When shipping multiple items, add additional internal support and avoid overfilling to maintain rigidity. Store packs in a dry environment to preserve cardboard strength and ensure reliable protection during transit.
