ABSTRACT:
A water-tight and heat-insulating air mattress structure having an air valve and a body made up of upper and lower layers, first and second LLDPE layers, first and second aluminum foil layers, and a nylon layer sandwiched there-between. The upper layer is applied on the first LLDPE layer which can retard the encroachment of water, while the first aluminum foil layer which can prevent the heat from dissipation is laminated between the first LLDPE layer and the nylon layer. The opposite layers, the lower layer and the second LLDPE and second aluminum layers, are applied in the same order as the above layers, and thus laminating and sandwiching the nylon layer there-between to form an air mattress structure with the advantages of both water-tight and heat-insulating.
