PMMA square airless pump jar 50g High-end luxury cosmetic packaging

A square airless jar is a container design commonly used to store and distribute cosmetics and skin care products. It combines a square look with airless technology.

Airless technology is designed to minimize the contact between the product and the outside air and prevent the product from oxidation, contamination or deterioration. This technology uses a special design that does not introduce outside air into the container when in use, but through a special push rod or pump system to push out the product.

Compared with the traditional round container, the square cylinder has a more modern and special appearance. They may be made of a variety of materials, such as plastic or glass, and often have a variety of capacities to suit the needs of different products. This design also makes the product easier to pack, transport and display.

This container design is often used in high-end skin care or makeup products because they offer a longer shelf life and better protection, while also looking attractive.
