What is the Advantage and Disadvantage of Custom Empty Loose Powder Containers

Glass Containers
Sand known as silica is the main ingredient of glass, mixed with metal oxides, sodium carbonate and other trace elements. Jars made of glass are popular for packaging emulsions, since they provide ease for removal of the product with the fingers. A key benefit of glass is that it has a decorative and clean look. The three main types of glass are borosilicate, treated soda-lime and regular soda-lime. Each one has unique chemical properties. Small thick wall glass jars are used for eye shadow, lip gloss and cream products. Larger glass jars are used for foundations, makeup removers, creams and powders. Amber glass jars are designed for bath and body products that don't have clear colors. When sodium ions are reduced, glass becomes a more chemical resistant form of cosmetic packaging.

Plastic Containers
A wide variety of cosmetic packaging is made from plastic, due to its convenience and hygienic qualities. Unfortunately, plastic tends to contribute to a large amount of waste and once it is opened, products usually must be consumed immediately. One of the main reasons plastic is such a popular material is due to its low cost. It's also lightweight, flexible, unbreakable and durable. On top of that, it's odorless and has a pleasant appearance. The main disadvantage to plastic is its physical stability, making it susceptible to absorption, stress cracking and crazing. Resistance to ink and other chemical substances can limit its use for certain types of packaging. The most common type of plastic used in cosmetic packaging is PP. Other plastics include PET and acrylic ingredients. Acrylic plastic has the appearance of glass but doesn't break like glass. From an aesthetic perspective, plastics can be made in various colors or tints, depending on the material.
