ABSTRACT:
A raft apparatus having inflation flotation structures which are capable of heat sealing for assembly thereof wherein one or more flexible buffer members of not heat sealable material are adapted to shield portions of the panel members of the flotation raft from heat sealing to surrounding areas to thereby form an effect seal particularly by allowing heat sealing operations to be formed upon already assembled sections. At least one of the two panel members will be inflatable and will include a buffer member positioned therein to shield the heat sealing point thereof from the remaining portion of the inflatable structure member to prevent undesired heat sealing thereof during heat sealing of the interconnection between the two main panel members.
