The performance of the product itself mainly includes the appearance, physical state, strength, structure, weight, value and danger of the product, which is the first problem to be considered when packaging.

2. Promote ideas

Promoting commodity sales is one of the most important functional concepts in packaging design. In the past, people mainly relied on the sales promotion and introduction when buying goods, but now supermarket self-selection has become the most common way for people to buy goods.

3. The concept of production

While ensuring the beautiful appearance, packaging design must consider whether the design can achieve accurate, rapid and mass production, and whether it can help workers to process, shape, package and seal quickly and accurately.

4. Storage conditions: Stacked storage should be adopted, and the compressive strength of the package should be investigated. In addition, storage can also be divided into indoor storage and outdoor storage. The former should pay attention to moistureproof, mildewproof and waterproof. The latter should pay attention to rain, snow, sunshine and wind.
