1. Ensuring the safety of commodities and consumers is the most fundamental starting point of packaging design.In the design of commodity packaging, safety protection measures in storage, transportation, exhibition and sale, carrying and use and other aspects should be considered according to the attributes of commodities. Different commodities may require different packaging materials.At present, the material that can choose includes metal, glass, pottery and porcelain, plastic, card paper to wait.When choosing packaging materials, we should not only ensure the seismic, compressive, tensile, extrusion and abrasion resistance of the materials, but also pay attention to the protection of the goods from sun, moisture, corrosion, leakage and fire, so as to ensure that the goods are intact under any circumstances.

2. Promotion concept promoting product sales is one of the most important functional concepts in packaging design.In the past, when people buy goods, they mainly rely on salesmen's promotion and introduction, but now the supermarket has become the most common way for people to buy goods.In the process of consumers opening shopping, product packaging naturally ACTS as a silent advertisement or silent salesman.If the product packaging design can attract the attention of consumers and fully stimulate their desire to buy, then the packaging design truly reflects the concept of promotion.
