Glass cosmetic containers are catching on in popularity, because of their low MOQ availability, expensive look and feel, and eco-friendliness. But how much do you actually know about glass cosmetic jars?
Strap in - it's time for a crash course in three easy steps:
ONE: Material Classification
Here are your glass choices: Quartz glass, silicate glass, soda lime glass, fluoride glass
TWO: Shape Classification
1. Round: Circular cross-section of the bottle - the most widely used shape
2. Square: Difficult to make, but seems like more and more beauty companies are starting to use square glass jars.
3. Curved: It also has a circular cross-section, but a curve in the y-direction (height).
4. Oval: Has a unique shape, but smaller capacity.
THREE: Advantages of Glass Packaging
1. A glass material has good barrier properties, and can prevent oxygen or other gases from reaching the inner contents.
2. Glass bottle can be recycled, thereby reducing packaging cost and opening up the ability to have a "customer recycling" program.
3. Easy to check the packaging color and quality.
4. In health and safety terms, glass has a good corrosion resistance, making it suitable for acidic substances.
Last piece of advice: For oils, use a darker colored glass; it can be reduce exposure to ultraviolet radiation by 90%. In addition, plastic material can destroy oil qualities and/or leech harmful chemicals into the oil base.
