<p>PURPOSE:To increase an adsorbing function of juice from meat and fish, by heat-sealing or sticking a highly water adsorbing resin on the surface of a low fusing point synthetic resin layer in the inner face of a tray. CONSTITUTION:The inner face of a tray, which comprises one or more high fusing point synthetic resin layers and one or more low fusing point synthetic resin layer, is made of a low fusing point synthetic resin. On the surface thereof highly water-adsorbing resin powders are heat-sealed or stuck and on the further surface a water-permeable material is applied. This water-permeable material comprises one or more high fusing point synthetic resin layers and low fusing point synthetic resin layer. At least, the low fusing point synthetic resin layer is of defibration threads or complex fibers forming one surface and it is webbed and the web or a non-woven cloth heat-treated of the web is stuck on the tray. A water-adsorbing ratio of 500-1,000 times is preferable for a highly water- adsorbing resin, bridged material of sodium polyacryl acid and potasium polyacryl acid, etc. for example.</p> |
