Abstract
The most used packaging material was plastic, but can cause environmental problems because it was not easily degraded. Therefore, it was necessary to look for alternative packaging materials that are easily biodegraded including edible film. The main raw materials for edible films were alginates and plasticizers including glycerol and sunflower oil. The objective of this study was to determine the characteristics of edible film composed of alginate, glycerol and sunflower oil. The study was carried out through the manufacture of edible films composed of various alginates concentrations (2, 3, 4, 5 and 6%), 10% glycerol and 0.01% sunflower oil. The characteristics tested included thickness, tensile strength, elongation, solubility, and rate of water vapor transmission. The results showed that all treatments met the edible film standard of the Japanese Industrial Standard. The various alginate concentrations used did not significantly influence the water vapor transmission rate and tensile strength but significantly affected the elongation, solubility and thickness of the edible film.

The rapid development of food products has the effect of increasing food packaging production
The research was conducted by making alginate edible film which refers to the method of Anward et al [6] with modification, namely dissolving sodium alginate in distilled water with variations in the concentration of alginate 2% w / w, 3% w / w, 4% w / w, 5% w / w and 6% w / w based on the volume of 100 ml solution . the solution is stirred until homogeneous at room temperature
Film thickness tended to increase with increasing alginate concentration, this was due to the increasing number of polymers that make up the edible film
Summary
The rapid development of food products has the effect of increasing food packaging production. Synthesis plastic is the most popular ingredient as food packaging material in the world. One effort that can be done is to reduce the use of plastic and replace it using biodegradable materials. Edible films can be used as biodegradable packaging. The use of alginate as a raw material for the manufacture of edible films has a good ability to protect the product against oxygen, carbon dioxide, oil, and improve the unity of the product structure [1,2]. If alginate is used as raw material for edible film, it will produce a neat film, high moisture permeability, and less flexible, so that efforts are needed to fix it, one of which is to add elastic plasticizer [3]
