Reasonable selection and design of plastic packaging containers and structures in cosmetic packaging

In the cosmetics industry, if the quality of cosmetics is the "first life", then the quality of cosmetic packaging is the "second life". Reasonably selecting the packaging structure of cosmetics according to the performance characteristics of cosmetics and consumers' preferences can improve the added value of cosmetics and show their charm.

Functional

Cosmetic packaging containers must have three basic functions: protection, storage, transportation.

First of all, it must be able to reliably protect the contents, and must not deform or deteriorate the contents, otherwise it will lose its function as the most basic protection of goods as a container. Therefore, the packaging material should first have a certain mechanical strength, which can ensure that the content is intact under the action of a certain external force, and has certain compressive resistance, impact resistance, bending strength, etc.; At the same time, it needs to have a certain hardness and stiffness, which can ensure that the overall shape of the product is intact.

The second is to have a certain barrier performance, for this can choose ethylene/vinyl alcohol copolymer (EVOH), polyester (PET) or composite plastic materials, and use aluminum foil for sealing at the mouth of the bottle, in addition to the interaction between fragrance and materials, add a protective coating; Third, it is also necessary to consider the climatic environment and chemical resistance. According to the needs of the actual conditions, optimize the selection.

Hygiene and safety

Since cosmetics are in direct contact with the human body, the requirements for product hygiene and safety performance are high. In order to ensure its health and safety performance, it is necessary to control the source of raw materials, production processes, and the environment of plastic materials.

Operation adaptability

In order to facilitate the packaging and printing of plastic packaging containers for cosmetics and adapt to mechanized operations, its container materials should have good heat sealing performance, printing adaptability and packaging mechanical adaptability. Compared with other materials, plastic materials have poor printing adaptability. Most packaging containers need to be formed before printing, which complicates the printing process. Therefore, it is necessary to select packaging materials with appropriate operability for the structural design of packaging containers. Convenient for printing and packaging operations, mechanized operations.

Artistic aesthetics

Unique packaging container shapes often have a strong appeal to consumers. Through the unique container shape design, the product and packaging create a subtle synergy effect, while creatively reflecting the individuality and characteristics of the product. Our common plastic bottles are mostly square, barrel, or tapered and spherical. Then we evolved into more complex forms within these basic forms. The single basic form often makes people feel monotonous, so it is changed or combined with each other in the design to make the shape more vivid, abundant and dynamic.

At the same time, in order to design a unique bottle shape with personality beauty and shape beauty, it is necessary to change the line, surface and shape of the cap, neck, shoulders, abdomen and other components. Take an example: the overall shape of the skin care body shampoo is designed from bottom to top, from round to oval stretch and extension, smooth and lively shape, according to the principle of ergonomics to design a moderate container size, suitable for grip, convenient for consumers, add wavy curves to the bottle body, produce a bumpy and undulating effect, first increase the friction, so that the product is easy to grasp in the hand, not easy to slip, but also full of dynamics. The color is designed to be clear and transparent, giving people a fresh and natural feeling, full of fashion charm. Well, this must be a container shape designed for young girls.
