Here are some common types of glass used for packaging:

1. Sodium calcium glass

Characteristics: Sodium calcium glass is one of the most common types of glass, mainly composed of

sodium silicate, calcium silicate, and silicon dioxide. It has good chemical stability and transparency,

light resistance, heat resistance, and relatively low cost. There are no harmful substances, it is an

environmentally friendly, safe, and reliable container material.

Usage: Widely used for packaging food, medicine, cosmetics and other products, such as common

honey, jam, vinegar, etc.

2. Borosilicate glass

Features: Borosilicate glass has the characteristics of lightweight, high temperature resistance, corrosion

resistance, and good optical properties.

Usage: Commonly used for advanced cosmetics packaging, pharmaceuticals, and foods that require

high-temperature treatment. In addition, borosilicate glass is also commonly used in laboratory utensils

and kitchenware.

3. Lead glass

Characteristics: Lead glass, also known as crystal glass, has a unique luster and transparency due to

the presence of a certain amount of lead. It has a high refractive index, which produces rich color

changes when light propagates through it.

Usage: Mainly used for high-end liquor and luxury perfume packaging to show its noble and elegant

quality.

4. Color glass

Features: By adding different metal oxides (such as cobalt oxide, manganese dioxide, etc.) to glass, various

colors of glass can be produced. These colored glasses are not only beautiful and elegant, but also have

certain shading and protective properties.

Usage: Widely used in pharmaceutical bottles and light resistant cosmetic glass bottles. For example, brown

essential oil bottles are used to block the damage of ultraviolet rays to drugs.

In summary, different types of glass are widely used in the packaging of various products due to their

unique properties and advantages. 

When choosing glass packaging, it is necessary to comprehensively consider factors such as the

characteristics of the product, market demand, and cost.
