was 180 u00b0 c the die temperature was 135 u00b0 c the properties of the net shaped articles 105 made using the combinations of example a through example d were measured and listed in fig5 by adjusting the proportions of components in the compositions and the processing temperatures net shaped articles 105 with various levels of hardness may be made to satisfy different applications of course the application of the net shaped article 105 is not limited and can be formed into any products selected from the group consisting of a bathing ball net a drain strainer a geogrid etc as shown in fig6 the net shaped article has its one end sealed through for example a heat stack process or any usable methods known in the art so as to become a net bag 105 for packaging an agricultural product 106 in addition to well accommodating articles since the net bag 105 has the net structure that supports good ventilation the agricultural products contains therein are unlikely to get rotten referring to fig7 a bathing ball net is made by knotting or otherwise shaping the net shaped article the net structure provides relatively large area for contacting with cleaning agents so is more capable of producing and retaining lather under friction since the biodegradable bathing ball net includes pbs having a relatively high heat deflection temperature it is unlikely to deform when it is brought into contact with shower water at a relatively high temperature referring to fig8 the net shaped article may be configured as a drain strainer 105 in order to prevent a drain outlet from being clogged by food residue the drain strainer 105 is disposed in a sink strainer 107 for catching food residue when the.
