Bespoke Return Packing Boxes

At MTD Ltd, we supply high-quality bespoke mailing envelopes designed to meet the specific needs of medical logistics, sample returns, and healthcare correspondence.

Available in any custom size, our envelopes are ideal for pairing with compliant inner packaging or for use in general medical and laboratory mailing. Manufactured from durable materials, they ensure secure delivery and a professional presentation—whether you're shipping documents, sample kits, or flat medical items.

• Fully customisable sizes to fit your application
   
• Durable, professional-grade construction
   
• Suitable for medical, clinical, and research use
   
• Ideal for pairing with compliant packaging systems
   

While not UN3373-compliant on their own, our envelopes integrate seamlessly into broader compliant transport solutions when used as part of a multi-component system.
