The deceased person must be placed in either a heat-sealed polythene body bag, it should be noted some countries require an inner metal or zinc liner container within the coffin.
A more modern approach is a new material called Bio-seal which is a mixture of both, best described as a metallic body bag. This material melts together when heat is applied creating an air and water tight hermetical seal require for air carriage.
The pleasing nature of Bio seal unlike a metal or zinc coffin liner, is that on arrival it can be opened simply with the use of scissors, making it much easier for the Funeral Director to open and allow the family to see their loved one once they are home.
Once sealed in the manner described the person who has died is placed in the coffin/casket of choice, which is then wrapped for its protection and safety in an outer cardboard coffin. This is generally done to protect the coffin or casket so it may be used on arrival at the destination for the funeral.
This casket is then wrapped in an outer material called sisal craft, which is best described as a waterproof tar paper to keep the coffin protected and dry during air transit.
During air carriage the casket must be identified clearly with the name of the Consignee, the destination and the deceased’s name.
