Envelope polyethylene C5 size 175 x 240mm with UN3373 compliant labelling for transport of category B biological samples to P650 packaging instruction

These flexible envelopes are made from lightweight polyethylene and together with a rigid secondary can help to minimise postage costs enabling many sample packages to be mailed at large letter rather than parcel rates. They are available in C4 or C5 envelope sizes, supplied in packs of 500 or 100 envelopes and are pre-printed with appropriate UN3373 packaging instruction requirements. They can even be customised for repeat mailing to the same address if required. Please enquire for further details. NOTE: minimum ordering quantities will apply.

UN3373 Standard – Key Requirements
The P650 packaging instructions for liquid substances state:-
a. The primary receptacle(s) shall be leak proof;
b. The secondary packaging shall be leak proof;
c. The primary receptacle or the secondary packaging shall be capable of withstanding, without leakage, an internal pressure of 95 kPa (0.95 bar);
d. If multiple fragile primary receptacles are placed in a single secondary packaging, they shall be either individually wrapped or separated to prevent contact between them;
e. Absorbent material shall be placed between the primary receptacles(s) and the secondary packaging. The absorbent material shall be in quantity sufficient to absorb the entire contents of the primary receptacle(s) so that any release of the liquid substance will not compromise the integrity of the cushioning material or of the outer packaging;
f. Either the secondary or outer packaging must be rigid.
The packaging must be of good quality and strong enough to withstand the shocks and loadings normally encountered during transport. It must prevent any loss of contents that could occur due to vibration or changes in temperature, humidity or pressure.
