The performance of packaged products: mainly including the physical state, shape, strength, weight, structure, value and danger of the products. This is the first consideration when packing.

Product status: mainly solid, liquid, gas, mixed state and so on. Products in different states have different packaging containers.

Product appearance: mainly square, cylindrical, polygonal, irregular and so on. The packaging should be designed according to the appearance characteristics of the product, and the packaging should be small in size, good in fixity and stable in storage, which meets the requirements of standardization.

Product strength: For products with low strength and easy damage, the protective performance of packaging should be fully considered, and there should be obvious signs on the outside of packaging.

Product weight: For heavier products, special attention should be paid to the strength of packaging to ensure that it will not be damaged during circulation.

Product structure: Different products often have different structures, some are not resistant to compression, and some are afraid of impact. Only by fully understanding the product structure can different products be properly packaged.

Product Danger: For inflammable, explosive, toxic and other dangerous products, in order to ensure safety, there should be precautions and special signs on the outside of the package.

The influence of environment on products, products will encounter different environments in the circulation process, which will have different effects on packaging, so corresponding measures should be taken.

Transportation conditions: products will be affected by shock and vibration during transportation, and different transportation modes will have different effects on packaging. Mainly consider product fixing and buffering.

The choice of packaging method is very important for product protection. Only by fully understanding the product performance and circulation conditions, making several plans and making economic evaluation can we find a suitable packaging method.
