Mailing envelope 265 x 180 mm Polythene with bubble wrap liner printed according to UN3373 regulations for mailing Cat B biological samples

These padded envelopes are ideal for mailing biological category B samples in conjunction with the SpeciSafe mailing packs. The sample container, which must be 95kPa compliant, can be enclosed in the appropriate SpeciSafe mailing pack then placed inside the Mail Tuff envelope. This package then complies with the UN3373 P650 packaging instruction for transport by road for category B biological samples. What's more in most cases the size of the final package is small enough to post at large letter rates thus reducing postage costs by a significant sum.

Full instructions are printed on the envelope and are neatly hidden away once the envelope is sealed. Simply add sender details in the designated space, and your destination address label on the reverse for a quick and convenient outer packaging.

Envelope internal size is 260 x 175mm with a 45mm adhesive strip for closure
