Hard Card Backed Envelopes
Packaging Panda's carded envelopes are PEFC and FSC certified and crafted from strong, eco-friendly brown paper that's both reusable and recyclable. Designed for convenience, each envelope includes a secure peel-and-seal strip for quick and easy closure.
These rigid mailers come printed with a clear "Please do not bend" message, making them ideal for protecting delicate contents like photos, certificates, documents, and invitations during storage or transit. The sturdy board backing ensures your items remain flat and undamaged.
Pro tip: Choose a card-backed mailer at least 10mm larger than your contents to allow for a snug yet safe fit.
