Effect of Some Production Parameters on Net Wrap Used in Agricultural Products Packaging on the End Use Properties

Abstract

This research is mainly concerned with designing net wrap used for packaging agricultural products. Twenty seven samples were produced using polyethylene yarns. Warp knitted technique was applied to produce all samples under study using different parameters. Different parameters were studied including, inlay tape thickness 20,25 and 30 micron, inlay tape width 1,1.25 and 1.5 mm, pillar blades number 99, 101 and 213, treatment with ultra violet and anti static. Many tests were carried out in order to evaluate the net according to the final product needs such as tensile strength and elongation of net and inlay tape and linear meter tests. Some more results were reached concerning structures and materials. The results showed that there is a direct relationship between tensile strength and number of pillar, the more inlay tape width, the higher tensile strength of the sample become, the more inlay tape thickness per unit area the more tensile strength of the sample become, the more number of pillar yarns the lower elongation the samples become, and the higher pillar yarns per unit area the more linier meter weight the sample become.
