Board Backed Envelopes & Hard Backed Envelopes — Durable Mailing Protection

Discover our premium board backed envelopes, engineered for strength and reliability. Also known as hard backed envelopes, these rigid mailing solutions combine a stiff backing board with an envelope shell to deliver superior protection throughout the the postal journey.

Why Choose Board Backed Envelopes?

• Superior protection: The rigid board core resists bending, creasing, and damage. Whether sending important documents, certificates, photographs or prints, hard backed envelopes help ensure your contents arrive unscathed.
• Versatile sizing: Available in a full range of sizes (C3, C4, C5, C6, A-series equivalents, PiP / Royal Mail compliant sizes, and custom formats), so you can match the envelope exactly to your item.
• Professional appearance: The clean, firm structure presents items flat and neat, making a positive impression on recipients.
• Cost-effective in bulk: Ordering in bulk reduces unit cost and helps you maintain margins while providing outstanding value to customers.
• Efficient shipping compatibility: Flat, rigid envelopes ship easily through standard postal systems with less risk of damage or rejection.

Features & Specifications

• Board thickness & grade: We use high-quality rigid board (e.g. solid or reinforced backing) to maintain structural integrity without excessive weight.
• Envelope shell materials: Often kraft, white kraft, or lined paper shell to complement the board and offer a clean finish.
• Seal options: Available with peel & seal, gummed adhesive, or self-seal closures, depending on your preferences and handling needs.
• Custom formats: Windows, coloured shells, or bespoke dimensions can be supplied for special applications.
• Order quantities: From small runs for businesses to large wholesale orders, we cater to all scales.

How to Select the Right Hard Backed Envelope

1. Measure your item — allow a few millimetres of clearance on all sides.
2. Choose the envelope size — C4 and C5 are common for A4 / A5, C6 for postcards, C3 for oversized sheets.
3. Decide board strength — heavier board for delicate or heavy contents, lighter board for general prints.
4. Select closure type — peel & seal or gummed, depending on your packing speed needs.
5. Order margin — it’s better to have slight excess capacity than tight fits.
