1 Introduction

After 20 years of continuous exploration and practice, China's advanced packaging education has made great progress. The packaging discipline system and packaging education system that have been developed in parallel with the national packaging industry have become increasingly sophisticated. More and more universities and colleges have started packaging education. Universities and colleges have done a lot of work in exploring the concept of packaging higher education, packaging personnel training specifications, packaging education and the development of the industry, and achieved great results [1]. Packaging higher education provides a large number of high-quality talents for China's packaging industry, which greatly promotes the development of China's packaging industry.

With the rapid development of the socialist market economy in our country, a large number of products have flocked to the market and have gone abroad. The demand for packaging scientific and technological achievements and advanced packaging products has been increasing. This has created a huge impact on China's packaging industry, which has a weak foundation and has lagged technology. Pressure, therefore, in the development of advanced packaging education, requires the extensive application of modern scientific and technological achievements to meet the needs of high-quality talents for the development of packaging industry.

As the discipline of packaging engineering is an interdisciplinary, marginal, and rapidly developing emerging discipline, its service targets all industries in the production of industrial products. At the same time, conditions, backgrounds, and graduate services for packaging schools are established across the country. There are differences in the regions, and it is very important to study the specifications, models, and training methods for the undergraduate talent training [1]. For a long time, we have combined the “Research and Practice of Modern Packaging Talent Cultivation” project of the World Bank Loan Higher Education Reform Project of the 21st Century attended by Beijing Institute of Graphic Communication and Tianjin University of Science and Technology (formerly Tianjin Light Industry College). The professional social needs, industry development and personnel training have made some useful explorations. This article mainly describes the training mode, teaching methods and practice of packaging engineering undergraduate.

2 Requirements and Quality Requirements for Professionals in Packaging Engineering

2.1 Characteristics and Talent Requirements of Packaging Industry in East China

East China is one of the more developed regions in China. The packaging industry in the region is of the same class, high level, and wide range of radiation. Take the carton industry as an example. According to statistics, the sales volume of the carton industry in Shanghai was RMB 1 billion in 1990. The sales volume in 2002 increased to RMB 6 billion, with an average annual growth rate of 30%. There are 120 production lines for corrugated board and annual sales. There are nearly 10 companies with a total amount of 100 million yuan. Of the nearly 100 carton factories in Wuxi City, 6 have sales of more than 50 million yuan. The strong development momentum of the corrugated paper box industry in Shanghai, Zhejiang, and Jiangsu is mainly due to modern production technologies, including township enterprises with modern production levels that have gradually grown, and large-scale international paper companies that invest in China and bring high technology. They give The industry brings new ideas and new technologies in production and operation. At present, China National Packaging Technology Association's national China Paper Packaging Development and Production Base (Shengda Group Co., Ltd.), China Paperboard Development Base (Zhejiang Jingxing Paper Company), China Paper Products Nanotechnology Application Research Center (Shangfeng Packaging Group), etc. The large-scale packaging professional production bases and centers all settled in the Zhejiang area; at the end of 2002, the world's carton giant Japan Teijin Wang Co., Ltd. purchased Changzhou Changfeng Packaging Co., Ltd., which ranks first in Jiangsu Province, and tried to make it into China's carton packaging. The most powerful companies in the world [2]. In 2003, Asian Packaging Center and Asia Pacific Center Manufacturing Center were established in Hangzhou and Jiangyin respectively, injecting new vitality into the East China packaging industry. In addition to the paper and packaging industry, the development of plastic packaging, metal packaging, glass packaging, packaging machinery, and packaging printing has also been rapid.

The rapid economic growth in the Yangtze River Delta and more and more international investors are driving the rapid development of the packaging industry in this region. Only from January to April in 2004, Shanghai, Suzhou, Wuxi, Hangzhou, and other places have reached the number of companies that have recruited packaging and printing talents in our university. We also conducted surveys for graduates from 1996 to 1999. It was found that 53.5% of the graduates in recent years chose the Yangtze River Delta as the preferred working area, and 17.8% chose the Pearl River Delta.

According to statistics, in recent years, enterprises in need of packaging professionals in East China are packaging design (including packaging structure, packaging and decoration and advertising design, etc.), carton (carton), product sales, quality control, packaging production management, quality inspection, and packaging. Materials, packaging equipment and machinery and electronic products production companies. A certain percentage of students chose non-packaging industries.

2.2 The technical quality requirements of packaging practitioners

As mentioned before, the packaging industry covers a wide area and has a higher requirement for student ability. To this end, we have conducted surveys on the employment experience of employed students. Among the various factors related to the teaching process, the most valued by companies are: learning experiences (including curriculum setting, practice, minors, school performance, etc.) Graduation colleges (including school reputation, professional advantages, teaching and experimental conditions, etc.); professional knowledge (usually through packaging design example assessment); practical experience; comprehensive ability; Certificate) and so on. Therefore, in addition to the learning experience and school factors that cannot be controlled by oneself, the basic qualities students should possess include:

(1) Professional basic knowledge and professional knowledge Employers often send cadres in the personnel department to perform assessments at the recruitment site. The questions raised are not very professional, and more students are required to solve specific packaging design cases. This requires students to have a solid academic foundation, rich professional knowledge, but also need a certain degree of comprehensive analysis and engineering training background.

(2) Practical experience Many students mentioned in the questionnaire the requirements of the company for practical experience. Specifically, it is to see if the students have carried out related practical activities, especially packaging design training, research training and so on.

(3) Comprehensive ability is the ability to comprehensively use the learned knowledge to analyze and solve professional and technical problems. This profession involves a wide range of courses, and many kinds of miscellaneous courses, such as the lack of a strong comprehensive analysis and problem-solving ability, will not be able to effectively use the knowledge of the classroom to face the total packaging enterprises and the packaging needs of major companies.

(4) Expression skills include written expression and verbal communication skills. Modern packaging companies not only require engineers and technicians to have strong analytical and engineering design skills, but they also need to be able to skillfully use scientific and technical languages ​​to write various scientific and technical styles, and be able to express themselves accurately and sell their products in a verbal language.

(5) Computer application ability (6) Foreign language level Computer application ability and foreign language level are two basic requirements for modern enterprises for talents. For the packaging engineering students, the computer application ability is particularly important, mainly including packaging CAD technology and development, packaging design visual communication computer-aided design and other capabilities.

3 Exploration of training mode and training methods for packaging engineering professionals

3.1 Training mode

Packaging project is a combination of "work (process)", "art (surgery)", multi-disciplinary application of technology disciplines. For the four-year undergraduate education, it is unrealistic to let students master all the knowledge in the subject area. The purpose of the undergraduate training should be to cultivate students' abilities and to adapt to the needs of the market. In teaching practice, we set up two types of orientation courses (modules) according to the professional characteristics and the needs of the talent market[3]: First, the direction of "packaging technology and equipment", including the main courses of packaging technology research, packaging machinery and automation, etc. The curriculum group is mainly engineering courses. The second is the direction of "packaging system design." The curriculum is mainly focused on packaging design, management, and art courses. Students can choose according to market demand or personal interests, and can also be determined through relevant ability tests.

When it comes to "patterns," people often give the impression of "restrictions." The training mode mentioned here does not mean restricting students' development direction blindly, but refers to setting up a number of directions (modules) on the basis of forming the basic specifications of the packaging engineering profession. This is also a training mode for adapting the characteristics of the packaging engineering profession. Reflects a kind of flexibility. According to school conditions and industry needs, more or less unnecessary directions can be set in the future. In order to meet the requirement of "wide-caliber", the crossover and integration of each module should be reflected in the configuration of engineering elective courses.

From the perspective of curriculum system, the packaging engineering major should have the following six types of courses: wide-caliber engineering foundation courses, packaging technology foundation and professional courses, art courses, computer and test technology courses, related engineering elective courses and related humanities and social sciences Elective classes and so on. These six types of courses constitute the main framework for cultivating knowledge and intelligent structure of packaging engineering professionals. In teaching, we must implement the principle of unification of requirements in combination with teaching students in accordance with their aptitudes. On the one hand, we must adhere to the unified specifications of human resources, and on the other hand allow students to use their advantages to fully display their abilities, and also take into account the characteristics of each school. The content of compulsory courses should be small, precise, focused, and lay a good foundation. At the same time, it will appropriately increase elective courses and series of academic lectures in order to facilitate the expansion of knowledge and allow students to selectively take courses according to their director. To facilitate the cultivation of talented packaging talents under the same professionalism.

3.2 Teaching Methods Teaching methods are very personal things. Combining with the teaching practice of packaging engineering discipline of Jiangnan University in recent years, the author conducted a preliminary exploration of the undergraduate education and teaching methods of this major.

3.2.1 Classroom Teaching Classroom teaching is one of the main links in undergraduate teaching. The curriculum characteristics of the packaging engineering subject are: more hours (about 2650 in our school's packaging engineering); more courses (about 50 in our school); curriculum covers a wide range of subjects and involves many disciplines [4]; major professional foundations and professions The course materials update faster.
After understanding these characteristics, you can improve in the following ways to improve classroom teaching effectiveness:

(1) Straighten out the content of professional courses to avoid repetition and disconnection. Under the instruction of the syllabus, the teaching content was seriously discussed, and the curriculum of each course was introduced, which was used as the basic teaching document.
(2) Improve teaching methods, implement multi-media teaching, arrange self-study or extra-curricular reading, etc., to solve the contradiction of less contradiction between the less class hours and more content, the contradiction between the obsolete teaching materials and the rapid update of teaching content, and the backwardness of teaching methods.
(3) Major assignments or course design should be arranged for conditional courses. This is the necessary teaching link for comprehensive use of the learned knowledge to solve practical problems.
3.2.2 Practice Link As with the general application technology profession, practical teaching is an important part of the packaging engineering discipline system, and it is also the key to cultivating students' abilities. The practical teaching of packaging engineering generally includes teaching experiment, curriculum design, professional internship, skill training, graduation practice and graduation design. We highlight skills training and graduation assignments (including graduation internships and graduation design) to develop students' abilities.
(1) Skills training This practical module includes computer intensive training, packaging and decorating design, and product packaging design and practice. After five weeks, computer application capabilities, packaging and decoration, and software applications for packaging engineering are oriented toward The product packaging design process has a more comprehensive understanding.
(2) Graduation assignments Due to the severe employment situation in recent years, the employing units have also assessed graduates through trials, internships and other measures, which have a great influence on the graduation operations of the eighth semester of the major. In order to cope with this situation and ensure the quality of teaching as much as possible, we practice guidance, practice arrangements, school-enterprise agreements, and design process control.
