Packaging Technology Based on the Architecture of Packaging Engineering

Abstract : It is proposed that packaging technology is a technical science that processes the original elements or semi-finished products of packages into packages in accordance with a defined packaging scheme, and defines its status by analyzing the structure of packaging engineering. At the same time, a new professional curriculum system for undergraduate packaging engineering was demonstrated.

Keywords: technical science; packaging engineering; packaging technology; curriculum system

Packaging science and technology began to form disciplines in the 1950s, and today has developed into a comprehensive cross-science with independent disciplines. This is a highly applied technical science. At present, its structure and connotation still do not form a unified understanding and definition; in general, its theoretical system is called packaging science.

Due to the development of professional education in industrial production and packaging engineering, the development of packaging engineering is fastest, and the structure of the main body is also more clear terrain has become four major areas: packaging principles and materials, sales packaging design, transport packaging design and packaging processes and processes. It can be said that packaging engineering lays the backbone of the discipline of packaging engineering education.

This article through the analysis of the packaging engineering structure, the packaging process and process in this area has a new definition, thus demonstrating the status and connotation of packaging technology.

1 Technological concept and establishment of packaging technology

Technology is a type of technical science that processes raw materials or semi-finished products into the product's work, methods, and scientific theories of technology. There are various products in the society and in people's lives. Their processing technologies form a variety of technological knowledge and constitute a major area of ​​human science and technology civilization.

Packing studies is based on the package of commodity production and logistics process towels and the packaging engineering system formed by them, and studies their functional combinations, formation and development rules. It is a synthesis of both natural sciences and social sciences. Sex cross science. Its towel packaging engineering focuses on the research of packaging parts, and the law of forming packaging parts has been appointed; while logistics packaging science focuses on the research of packaging engineering systems to take full play of the rules of packaging functions.

In studying the regularity of the formation of packaging, according to the status of knowledge and the comprehensive characteristics of the discipline, the system is summarized as the above four major areas, the packaging principles and materials form the technical basis of packaging; the sales packaging design and transportation packaging design It is the planning area for package formation and the main body; the packaging process and process are the field of implementation for the formation of packages, followed by the frontiers of various packaging engineering technologies.

In the implementation of the process of forming a package, the packaging process and process theory plays a key guiding role, and its core technical science is packaging technology. This is a technical science that processes the original elements of a package or its semi-finished products into packages in accordance with a defined packaging scheme that is high-quality, efficient, economical, and civilized. In the process engineering technology of all kinds of packages, it plays an important role in guiding and guiding.

The determination of packaging solutions is the core content of packaging engineering and constitutes the field of packaging design. It is the technical science of studying what kind of packaging products form. From the packaging function theory, we can see that transport packages and sales packages are two types of packages that focus on different functional objectives. Therefore, packaging design has established two branches of technology science: transport package design and sales package design. Packaging technology is closely linked to packaging design. The packaging process is based on the design of the packaging program as the goal and basis. The packaging design must be based on the implementation of the packaging process.

2 The establishment of packaging functions and packaging principles

The packaging function is the basis for the existence of packaging and packaging. It is the beneficial effect of the performance of the packaging during its life. These effects are set scientifically by people based on the understanding and analysis of the packaging's life process.

From the functional perspective of packaging, we can see that for the purpose of functions, the packaging functions that people set can now be categorized as storage and transportation functions, sales functions, consumption functions, social functions, and manufacturing functions. Their properties are parallel, but their connotations must be subordinated. For a basic function, the protective function of the package [4]. Through the analysis of the purpose functions of the packaging, the technical science of another important branch of packaging engineering has been established, that is, the packaging principle and technology. This is the knowledge of the "internal correlation" of the package elements that must be taken into account when planning the intended function of the package. From the study of packaging materials, accessories, media, and contents to their interaction analysis, the principles and techniques of packaging become the guiding package design. Foundation. In view of the basic function of the protective function, the core knowledge of the packaging principle is the principle and technology of packaging protection. It contains the protection of physical stability, chemical stability, physiological and biochemical stability protection, structural stability protection and comprehensive stability. Protection and other multi-subject discipline theories and techniques. These basic discipline theories and techniques are often closely related to the related technological theories of food and light industrial products. They are an important area of ​​packaging content, and are therefore easily confused with the structure and system of packaging science and technology itself. Workers value and think.

In the research of packaging principles and technologies, packaging materials are important packaging elements and are the basis for packaging. It is the general name for the materials and accessories that make up the contents of the packaging. It is based on the science of materials and is rooted in the specific fields of packaging science. Its technical form is very active. Research on various packaging functions is directly linked to it. Associated, it is therefore inseparable from the principle of packaging to form the basic field of packaging engineering - packaging principles and materials technology science.

3 Packaging Engineering Knowledge System and Packaging Education

Through the above analysis, the basic framework of the packaging engineering knowledge system can be straightened out. Among them, packaging principles and materials technology science as the basic part of packaging engineering, there are two core courses, namely packaging protection principles and technology and packaging materials science; and packaging design as the main content of packaging engineering, according to the functional characteristics are divided into Sales packaging design and transportation packaging design. The packaging process and process keep close to the forefront of engineering technology. According to the practical application of the packaging industry, many areas of it have developed flexibly. For example, packaging machinery, packaging and printing, packaging automation, packaging materials, and container processing have all developed into relatively independent Branch; and packaging technology is the core of technical science in this area.

Given the current state of packaging education, it is necessary to make necessary adjustments and explanations for its curriculum system, especially packaging technology. Undergraduate packaging engineering major in packaging education, as a major in engineering, is a matter of course for packaging engineering. For some schools, depending on the characteristics of professionalism or focusing on professional sociality, packing school as their main subject may also be the right choice. In any case, the discipline system of packaging science and technology is the basic basis for the setting and planning of packaging engineering.

During the planning and construction period of the third set of textbooks for general higher education, the results and deficiencies of the first two sets of construction were summarized, the experience in long-term teaching practice was refined, and the disciplinary system of packaging science and technology was studied to form a more practical , More scientific packaging engineering courses and their systems. The professional curriculum planning of packaging engineering proposed in [6] should be a relatively scientific curriculum plan for the new century. This redefined the connotation of packaging technology and produced a new course, protective packaging principles and technologies.

As shown in Figure 1, the packaging material science and packaging protection principle and technology set up a solid professional foundation; sales packaging design and transport packaging design separation, enrich the professional knowledge of the packaging process and equipment settings and grasp The width of the professional and appropriate combination [7]. Two special courses, one by one, design and manufacture of packaging containers, and packaging and printing, have become the theoretical cornerstones of today's packaging industry, making the profession closer to reality. Other general professional courses are the nodes of professional knowledge. All institutions of higher learning can arrange courses based on merits and demerits. This cited some of the schools to provide a wide range of features.

4 Basic Connotation of Packaging Technology

The core content of packaging technology is the main packaging process in the packaging process as the main body, such as the container molding measurement, filling, sealing, wrapping, packaging media control, etc.; and talk about many related packaging processes, such as cleaning, drying , sterilization, labeling, printing, shelving, assembly and other processes; also involved in some auxiliary packaging processes, such as supply, selection, positioning, preheating, cooling, demagnetization, etc.; should introduce their basic theory, basic knowledge and Practical skills; and in these technological knowledge systems, closely integrate knowledge in the fields of mechanics, printing, and automation.

It can be believed that with the development of modern science, with the improvement of the degree of civilization of the packaging, this discipline will continue to increase its corresponding technology and level. In the industrialized production of packages, the realization of a defined packaging scheme for packaging design may or may require different packaging processes, packaging processes and technical methods. Therefore, the packaging process design, packaging quality control, and productivity improvement are important areas of research in the packaging process. The development of modern high technology has positively impacted the engineering and technology fields of packaging science and technology, especially the application of a large number of advanced manufacturing technologies in package processing, such as mechatronics, laser technology, digital technology, surface engineering technology, virtual technology, and Flexible technologies, etc., have penetrated or may have penetrated into the packaging industry. Therefore, the urgent task of packaging technology is to actively follow the pulse of the times, reflect the highlights of modern technology in a timely manner, develop the unique theory and knowledge of packaging technology, and provide services for packaging modernization. This is an important part that cannot be ignored in the connotation of packaging technology. .
