Air Filled Cushioning Material, Structures and Properties
(0) Air inflated cushion using pre-sealed two-layer plastic films forms air filled structural cushionwhen compressed air is charged to pre-sealed airtight chambers during packaging operation. The plastic filmsare made by co-extrusion of polyethylene/polyamide/polyethylene (PE/PA/PE) to keep required strength,permeability of the cushioning materials and easy production of the cushion. The air filled cushion structure iswhen regulated compressed air is charged into the chambers using controlled pressure gauge duringpackaging performance. Uniquely designed charge port to each chamber provides individual chamber withthe ability to work independently, hence ensures the protective function of packaging and allows the air cushionsto be easily manipulated to a given product to be packaged. Static cushioning performance tests to airfilled cushion materials at desirable air pressures showed that minimum cushion factor was about 4, and appearedat compressive strain of the materials from 55-80%. Dynamic impact to the samples with dimension of180 by 180cm at drop height of 76cm demonstrates relationship between impact mass and acceleration levels,indicating the suitability of the materials for a wide range of packaging application to electronic products anddevices. Overall packaging properties of the material relating to co-extruded film strength, permeability, sealingstrength of the plastic films were discussed.
