原则是普遍真理,基本准则,遵循的宗旨,和法。它们的主要作用是指导行动。包装科学应该有自己的学术理论体系。其它科学如会计学、物理学、工程学等都有自己的理论,何况包装呢? 包装是多种学科的综合。它包括种类繁多的产品、材料、容器、工艺、技术以及一定方面与包装有关的工作。同时,人们提出的任何包装理论都自然会遇到在相互联系的各个领域中如何应用的复杂课题。 The principle is universal truth, basic norms, the purpose followed, and the law. Their main function is to guide the action. Packaging science should have its own academic system of theory. Other sciences such as accounting, physics, engineering, etc. have their own theory, not to mention packaging? Packaging is a multidisciplinary synthesis. It includes a wide range of products, materials, containers, processes, technologies and packaging aspects of a certain area of ​​work. At the same time, any packaging theory put forward by people will naturally encounter complicated problems that are applied in various fields of interconnectedness.
