Benefits of technology

[0007]In view of the disadvantages in the known art, the object of the present invention is to provide a plasticizer added in biodegradable material, to improve the property of the biodegradable material, and facilitate the follow-up processes.

Problems solved by technology

Generally speaking, the treatment and recycling for plastics used in disposable applications after use are not economic and impose greater impact on the environment.
The treatment of contaminated plastics at present is nothing more than combustion or landfill, which invisibly increases the loading to the environment.
Therefore, the development of biodegradable material has become a high-profile issue.
Although the biodegradable material at present is environmentally friendly, the structure of such material is hard to be modified, and their products after different kinds of fabrication processes have disadvantages of fragility, low heat-resistance, insufficient viscosity and so on.
Therefore, the application of biodegradable materials is greatly limited, and the marketing products can only be used at low temperature.

Preparation of Plasticizer

[0034]The present embodiment includes the preparation of four plasticizers, which is described as below:

Case 1

[0035]5 g vegetable gelatin (vegetable hard shell capsule #0 produced by Dah Feng Capsule Industry Co., Ltd.) was mixed with 5 g water, then placed in an environment of 80° C. for 1 hour to obtain the plasticizer of the present invention (A001).

Case 2

[0036]5 g vegetable gelatin (vegetable hard shell capsule #0 produced by Dah Feng Capsule Industry Co., Ltd.) was mixed with 5 g lactic acid monomer, then placed in an environment of 130° C. for 4 hours to obtain the plasticizer of the present invention (A002).

Case 3

[0037]5 g animal gelatin (gelatin 260B sold by Buildmore Enterprise Co., Ltd.) was mixed with 5 g water, then placed in an environment of 80° C. for 1 hour to obtain the plasticizer of the present invention (A003).

Case 4

[0038]5 g animal gelatin (gelatin 260B sold by Buildmore Enterprise Co., Ltd.) was mixed with 5 g lactic acid monomer, then...

Abstract

The present invention relates to a Plasticizer, which is fabricated by mixing monomers of biodegradable polymer with bio-molecules subsequently to deal the mixture with thermal treatment. The Biodegradable material comprising the Plasticizer has high melt index which is contributive for the processing of thermal processing, and the microwave-tolerance and water-resistance of the material makes the material suitable for food packaging.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a biodegradable material, especially a biodegradable material containing a plasticizer.[0003]2. Description of Related Art[0004]The rise of plastic packaging material closely relates to the change of general lifestyle. The use of light, convenient packaging to facilitate food storage and transportation, as well as increasing the shelf life of food has become very important due to the pressure from high population growth rate and food shortage. Although plastic packaging at present can satisfy these demand, the consumption of plastic has exceeded 160 million tons annually, within which 35% is used as packaging material. The treatment of waste from the packaging material imposes huge impact on the environment, so the recycling of plastic and the study of degradable plastic have become more and more important.[0005]Biodegradable material has been generally defined as a material under suffic...
