Reasonable selection and design of plastic packaging containers and structure in cosmetic packaging
In the plastic bottle suppliers of the cosmetic industry, if the quality of the cosmetic is the first life, then the quality of the cosmetic packaging is the second life. According to the performance characteristics of the cosmetic and the preferences of consumers, a reasonable selection of the packaging structure of the cosmetic can improve the quality of the cosmetic. The added value shows its charm even more.
The functionality of plastic packaging
Cosmetic packaging containers must have three basic functions: *protection, *storage, and *transportation.
First of all, it must be able to reliably protect the contents, and the choice of container materials and the contents must not be deformed or deteriorated. If the color that people love cannot effectively protect the product, it is just a display for consumers, and it also damages the interests of consumers, and may even harm consumers, which violates the primary purpose of design to serve people.
Therefore, the packaging material should first have a certain mechanical strength, which can ensure that the contents are intact under the action of a certain external force, and have a certain compression resistance, impact resistance, bending strength, etc.; at the same time, it needs to have certain hardness and stiffness. degree, so that the overall shape of the small plastic bottle product is in good condition.
Second, there must be a certain barrier to performance. For this purpose, ethylene/vinyl alcohol copolymer (EVOH), polyester (PET), or composite plastic material - HDPE bottle can be selected, and aluminum foil is used to seal the mouth of the plastic spray bottle. In addition, the interaction between fragrance and material should also be considered, and a protective coating should be added.
Third, it is also necessary to consider the climatic environment and chemical resistance and optimize the selection according to the needs of actual conditions.
