简体中文 Have you ever found yourself drowning in a dazzling array of cosmetic jars and beauty containers, wondering which formula is suitable for your creation? Let's take a look at them and categorize them.
Glass containers-they are non-porous and can safely contain almost any ingredient. The challenge is that it is generally more expensive and requires more consideration when packaging, so it will not break during transportation.
Aluminum containers-they are safe for "pure" essential oils. However, be sure to use the type of container that is paired with the airtight lid.
Plastic containers-they have a wide range of prices, some are quite cheap, and are very suitable for samples for promotional purposes. They are also the most commonly used beauty containers in the health and beauty industry.
Polystyrene (PS)-It has excellent transparency and stiffness. It also has a good price point. Very suitable for dry products, such as eye shadow, glitter, perfume, etc. Since it is very hard, the impact resistance will be reduced. Most importantly, it will not hold any formulas that contain oil. The oil in the product will attack polystyrene and break it down. This incompatibility is most often described by users as "My cosmetic jar is broken!
Polypropylene (PP)-It has the ability to withstand higher temperatures during the filling process and the stem disinfection process. It has better chemical resistance, so it can hold a wider variety of ingredients compared to polystyrene tanks. The disadvantage of this tank is that it can handle extremely cold temperatures.
Polyethylene terephthalate (PET)-It has excellent resistance to formulas containing alcohol and essential oils. However, it does not provide resistance to high temperature applications, such as filling processes or sterilization.
