Abstract

The physical characteristics of bioplastic packaging can be influenced by variations in the duration of gelatinization and the type of plasticizer. This research was conducted to obtain the effect of variations in the duration of gelatinization and the type of plasticizer on the physical characteristics of bioplastic packaging films and to obtain the treatment that produces the best physical characteristics of the packaging. The experimental design used was a Randomized Block Design (RAK) with the first factor being the treatment, namely, the duration of gelatinization (D) which consisted of 3 levels of duration: 3 minutes, 5 minutes, and 7 minutes, and the second factor was the type of plasticizer (P) consisting of 3 types: 2 g of castor oil, 0.5 g of stearic acid and 1.5 g of glycerol with three repetitions resulting in 27 experimental units. The data obtained were analyzed using variance and if the treatment had an effect on the observed parameters, it was continued with Duncan's test. The results showed that the variation in the duration of gelatinization and the type of plasticizer of the bioplastic packaging film had a significant effect on the value of tensile strength, elongation at break, elasticity, water absorption, on and thickness of the bioplastic packaging film. The treatment of gelatinization duration of 7 minutes and the type of stearic acid plasticizer produced a bioplastic packaging film with the best characteristics, namely the tensile strength value of 18.28 MPa, elongation at break 7.34%, elasticity 255.52 MPa, water absorption 0.8%, and a thickness of 0.25 mm.
