The cosmetic industry uses a variety of materials in its packaging, including plastic and metal, and glass is one of the oldest packaging materials. The following information provides detailed information on cosmetic packaging materials.
glass container
Sand, known as silica, is the main component of glass, mixed with metal oxides, sodium carbonate and other trace elements. Jars of emulsions made of glass are popular because they are easy to remove with the fingers. The main advantage of glass is its decorative and clean appearance. The three main types of glass are borosilicate, treated soda-lime and regular soda-lime. Each has unique chemical properties.
Borosilicate glass is more chemically inert than soda lime glass because it contains boron and/or aluminum and zinc. The glass contains sodium hydroxide, which is mixed with other ingredients and trace particles into the distilled water in the glass container after one year of storage. Treated sparkling water can be used or stored for long periods of time, while regular sparkling water is more chemically resistant and suitable for general purpose packaging.
Smaller thick-walled 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 in opaque colors. By reducing sodium ions, glass will become a more chemically resistant form in cosmetic packaging.
plastic container
A wide variety of cosmetic packaging is made of plastic due to its convenience and hygienic properties. Unfortunately, plastic tends to create a lot of waste, and once opened, the product often has to be consumed immediately. One of the main reasons why plastic is so popular is its low cost. It's also lightweight, flexible, and durable. Best of all, it's odorless and pleasant-looking.
The main disadvantage of plastic is its physical stability, which makes it prone to absorption, stress cracking and cracking. Resistance to inks and other chemicals can limit its use in certain types of packaging.
The most commonly used plastic in cosmetic packaging is PP. Other plastics include PET and acrylic components. Acrylic plastic has the look of glass, but doesn't crack like glass. From an aesthetic point of view, plastic can be made in a variety of colors or shades, depending on the material.
