Triplast A4 Envelopes Board Back Manilla Pack of 10

Ensure your important documents and flat items arrive in pristine condition with Triplast A4 Board Back Manilla Envelopes. Designed for maximum protection, each envelope features a heavyweight 120gsm kraft paper front and an extremely rigid 1000-micron solid board back. This robust construction keeps contents like certificates, contracts, photos, and artwork completely flat and crease-free during transit. A bold red “Please Do Not Bend” warning printed on the front acts as a clear handling instruction for postal workers, helping to prevent damage. These C4-sized envelopes (324mm x 229mm) are lightweight for cost-effective postage yet exceptionally sturdy. The convenient peel-and-seal adhesive strip provides a fast, strong, and mess-free closure, eliminating the need for tape or glue. The smooth kraft surface is perfect for handwritten addresses or printed labels for a professional finish. As an eco-conscious choice, these envelopes are made from 100% recycled material and are fully kerbside recyclable and biodegradable. This pack contains 10 envelopes, offering a reliable and sustainable mailing solution for your most valuable items.
