Different formulations for each compound were made into polybag used for cultivation of oil palm seedlings for strength and mechanical properties studies. One group of sample was exposed under normal sunlight to initiate degradation and another group of sample was placed under shaded area for five months. All samples were tested for tensile strength to determine the degradation effects. The tensile strength of directly exposed sunlight samples and shaded area showed up to 50% and 25% degradation respectively. However, similar reduction of Young's modulus for all samples was found for both exposures. Structural investigations were done using FTIR to detect deformation. The natural additives that were used in the studies were all natural and environmental friendly

The photodegradable polyethylene (PE) mixtures were formulated with added polypropylene (PP) and photodegradant (RM master batch) and tested in oil palm seedlings cultivation. PP is known to have photodegradable ability and RM master batch is proven to induce photo degradation of polyethylene. Thus, the mixture of these three components according to different ratios was processed into agricultural plastic films. There are four formulations that are tested in this study, namely T1 (80% PE:20% PP:5% RM master batch), T2 (70% PE:30% PP:5% RM master batch), T3 (80% PE:20% PP:3% RM master batch) and T4 (70% PE:30% PP:3% RM master batch). All formulations except control sample were added with photodegradant to impart degradation reaction and compatibiliser w...

Additional of PP into PE could impart extra mechanical strength of the final products. This study analysed the mechanical strength and structural changes of different six PE/PP blends with oxidative photodegradant. Miscibility of PP into PE resin during compounding process was made possible with acid compatibiliser (C1). Objective: In order to induce degradation of the blends, the compounded materials were added with oxidative photodegradant. Different percentages of photodegradant were added into PE/PP composite to test its ability to induce photodegradation upon weathering. Results: In this study, it is proved that by blending PE with minor percentage of PP have contributed to the incremental of mechanical properties on the product before being weathered. The PE/PP blend samples were tested and it was found that by adding 20% and 30% of PP into PE during compounding resulted in increased tensile strength and elongation at break with lesser effect on Young's modulus. After weathering for one and two months, it is shown that tensile strengths of samples were decreased.
