How strong are your boxes? Our material is rated at 32 ECT strength. The materials we use to create your custom box are rated to carry up to 50 lbs of materials.  If the contents of your box are over 50 lbs, we would recommend a double-wall or triple-wall constructed box. Currently, we don't offer double/triple wall boxes. We would recommend contacting a box manufacturer in your city/state to inquire about their availability.  - [Artwork Guidelines](https://support.fantastapack.com/artwork-guidelines?hsLang=en) - [Ordering Packaging](https://support.fantastapack.com/ordering-packaging?hsLang=en) - [Products & Materials](https://support.fantastapack.com/products-materials?hsLang=en) - [Production & Shipping](https://support.fantastapack.com/production-shipping?hsLang=en) - [Customer Account](https://support.fantastapack.com/customer-account?hsLang=en) - [Default HubSpot Blog](https://blog.fantastapack.com/) [![Chill listening crop-3](https://support.fantastapack.com/hs-fs/hubfs/fpk%20logo.png?width=102&height=50&name=fpk%20logo.png "Chill listening crop-3")](https://www.fantastapack.com) Thanks for Visiting the Fantastapack Support Center.
