Dears,
In BE airport health authorities deliver laissez-passer for coffins following the agreemenst fo Strasbourg, which include some criteria regarding the coffin, one being a zinc inner coffin.
Would your authorities agree for a funeral compagny tu use, instead of such an zinc inner coffin, a flexible matal conatiner (aluminium roll), sealed by heat, claiming to be airtight and watertight, without any leakage (odor, liquids) and claiming to provide a level 4 biohazard containment for human remains?
