More About "Board Envelopes"
Board envelopes — also called all-board or rigid board envelopes — are constructed from board throughout rather than standard paper. This gives a significantly higher level of stiffness than board-back envelopes, making them the choice for contents that cannot flex at all: high-value prints, framed artwork, thick documents, rigid inserts and items where even minor board flex would cause damage.
Board weight typically runs to 350–600gsm depending on the variant. The range covers over 15 products across over 70 sizes. All board envelopes are peel & seal for fast, reliable dispatch.
Board Envelopes vs Board-Back Envelopes
- Board-back envelopes — rigid card backing on the rear panel only; front face is standard paper. Suitable for most photographs, certificates and flat documents.
- All-board envelopes — board construction throughout; maximum rigidity for high-value prints, artwork and rigid inserts where the slightest flex is unacceptable.
Benefits of Board Envelopes
- Maximum rigidity — all-board construction prevents any flex or bend throughout transit.
- 350–600gsm board — substantial construction that protects high-value contents.
- Peel & seal — permanent adhesive strip for fast, reliable closure.
- Size range — over 70 sizes to match your specific application.
- Do Not Bend suitability — the preferred format for artwork, prints and items requiring strict flat delivery.
Frequently Asked Questions
What is the difference between board envelopes and board-back envelopes?
Board-back envelopes have a rigid card lining on the rear panel only — the front is standard envelope paper. All-board (board) envelopes are constructed from board throughout and offer maximum stiffness. For most photograph and document applications, board-back is sufficient. All-board envelopes are used where the very highest rigidity is required, such as for high-value artwork, architectural drawings or thick rigid inserts.
What board weight are board envelopes?
Board envelope weight varies by product — typically 350gsm to 600gsm. Higher board weights provide greater rigidity and crush resistance. Check individual product listings for the specific board weight if this is a purchase requirement.
Are board envelopes Royal Mail compatible?
Yes — board envelopes are posted as standard items. The board construction adds weight, so most packed board envelopes will fall into small parcel rather than large letter. Always weigh the packed item before assigning a postage rate.
