<p>PURPOSE:To obtain a shock-absorbing material, encapsulating a high pressure and capable of being bent or deflected, by a method wherein two sheets of composite films are put together to form pouched parts and flat parts alternately. CONSTITUTION:A shock-absorbing material 1 is formed by using two layers of plastic films. High-pressure pouched parts 4 are formed by an upper layer film 2 with a predetermined space from one side S1 of a material sheet to the other side S2 thereof so as to have semi-cylindrical shape. An lower layer film 3 is bonded to the film 2 by heat seal except the high-pressure pouched parts and thus the flat parts 5 are formed. High-pressure air, having the pressure of 1kg/cm<2> or higher, is encapsulated in the high-pressure pouched parts 4, therefore, the material 1 stands well against a high external load and developes a shock-absorbing effect. It is easy to bend the material sheet 1 in parallel to the length of the sheet at the flat parts 5. The material 1 is wound around a glass bottle A and is accommodated into an outer box B. The flat parts may be bent along the corner of the box.</p> |
