YOUR ITEM
Selecting the right format

Start with the contents, not the envelope.

Consider dimensions, bend sensitivity, surface protection, required capacity, cushioning, presentation and the journey the pack will make.

  • What are the item dimensions?
  • Can the contents bend safely?
  • Do you need cushioning or only rigidity?
  • Is branding or printed information required?
  • What quantity and destination are involved?
Need a variation?

ENVOSOL lists custom manufacturing capability. Share the application and the changes you need rather than forcing the shipment into the wrong standard format.
