Abstract
The development of edible films has been widely applied in recent years as an environmentally friendly food packaging, increasing shelf life and improving food quality. One of the biggest challenges in the process of making edible films is the printing process. The resulting edible uniformity level can reduce the main function of the edible film as a food packaging. Therefore in this study the design of edible film printing machine was carried out using knife casting and can adjust the height of the edible solution automatically. The printing machine was composed of 3 main components namely plate, pouring and automatic casting knife. It was also designed for laboratory scale with the dimension of 1200 cm length, 50 cm width, 30 cm height, pouring speed of 28 ml/sec, plate speed of 20 mm/sec and the accuracy of knife casting thickness of 99.3%. By the uniform thickness and shorter processing time for printing, this machine was expected to be the solution for the realization of Indonesian green packaging in industrial revolution 4.0.
