Research On Straw Packaging Container Design

At present, all countries in the world are actively engaging in expolring the green packaging material and packaging design research. Packaging industry in China also enters a new period of development. Based on the sustainable green packaging design concepts, this thesis made a deep research on the straw packaging container design, which featured by solving the dry forming technology application in straw packaging container.Through the study towards material properties and hot dry-forming mechanism, this thesis gave the complete process parameters and process formula in order to perfect the form design.Combining the artistic design theoretical approaches with wood science and packaging technology, this thesis developed the straw packaging container design. This research applied the morphology transformation law into the straw packaging design and explored the feasibility as well as establishing the system composed by structure, material and process integration. Particularly, this thesis focuses on the innovative research and development of the straw packaging container, featured by the realization of the technology innovation in the green packaging design.This thesis also made a research of the factors contributing to the molding of the packaging container, which includes components of straw, particle size, sizing amount, molding temperature, molding pressure, molding time, performance (waterproof, anti-oil, anti-alcohol, etc.) as well as the impact of the parameters. It analyses the rational molding pressure, temperature, control parameter in industrilization and requied strength and stiffness in the packaging. The experienment, with the straw debris as material added green additives, developed the straw pakaging container which has uniformed thickness, dense, smooth surface in order to meet the the green, environmental protection and biodegradable performance requirements.On the experiment approaches, this thesis made an experimental research of dry-form technology, additives and process technology. By the single-factor test of several additives on the primary test, it identifies the use of various additives on the performance of packaging container law, as well as the additives'effect on the performance of the packaging container. Through experiments to determine the main factors and their range in straw containers forming. Utilizing the orthogonal experiment to make a range analysis of the results. Getting the conclusion of the optimum molding process parameters.Designing by performance testing and compression properties of materials, this thesis explores the mechanical properties of straw on plant containers modeling effects. Using finite element software simulation and analysis of packaging containers, this thesis improve the straw packaging design and shed a light into improvement of container structure and development of mold.This thesis achieved the innovations not only in theoretical aspect but in applied aspects. Combing the material science theory, packaging engineering theory with arts design theory together, which involved in the straw packaging design. Thus forming the merge of multi-disciplines and creating the innovative theoretical system. Complied design, process with material together as the guidance of the research, straw as basic material, added the green biodegradable additive, this research using the approaches such as high pressure and high temperature, dry form to produce the straw packaging container.
