Glass is a material favored by many brands and consumers. On the one hand, glass looks beautiful with its superior transparency and gloss. On the other hand, glass can be recycled over and over again, making it an environmentally friendly material. Both practical and aesthetic, glass has a certain appeal.

For many families, glass is a particularly suitable container for packaging food. It maintains the quality of food and beverages well and safely in the long run. Common examples include a variety of ready-to-eat deli foods, jams, honey, wine, or catering dishes (ready-to-eat foods, soups, desserts, etc.). Suitable for a variety of scenarios such as homes, shopping malls, and restaurants, Glass Jam Jars, Glass Honey Jars, Glass Wine Bottles, etc. I’m sure you’ve seen them all before.

In fact, the main glass used in the food market is soda-lime glass, also known as Type III glass. Soda lime glass consists of silica, sodium, limestone, and crushed glass. This glass is widely used in the manufacture of bottles and jars. It accounts for about 90% of glass production. So why do many foods on the market prefer glass packaging? There are several common reasons:

Material: Glass packaging is more stable to contents, does not release harmful substances to contaminate food, and does not react with ingredients in food. Barrier properties are better, and with the right fittings, glass can be completely sealed. This means that the glass provides a high degree of safety for the end customer.

Aesthetics: Very popular in the decorative products market. The transparency and brightness of glass enhance the product it contains, allowing consumers to clearly see the contents of the package. Brands also utilize this property to promote their products. In addition to transparency, glass has a shiny appearance and can be presented in different colors.

Positioning: Its neutral texture and aesthetic appearance make it a very popular material for high-end food packaging. It is ideally suited as a closed container and guarantees the quality of all types of food and liquids inside: sauces, canned vegetables, appetizers, honey, ready-to-eat foods, soups, etc.

Heat-Resistant: Glass is a more heat-resistant material compared to plastic. It is easy to clean, can be sterilized at high temperatures, and can be stored at low temperatures, but it should be noted that Type III glass cannot withstand high impact temperatures exceeding 42°C.

Ideal for Extended Shelf Life: Due to its heat resistance, glass packaging can be directly sterilized or pasteurized. The closure effectively blocks the entry of light and oxygen, thus maintaining the freshness, quality, and taste of the food. Both processes extend the freshness of the package contents and guarantee a long shelf life.

Unlimited Recyclability: The process of collecting and recycling glass is always ongoing and highly effective. Because soda-lime glass contains a percentage of recycled glass, like metal, recycled glass retains all its aesthetic and mechanical properties. According to CITEO, the glass recycling rate in France will be 88% in 2021.

Reusable: Glass is a non-porous, completely closed material that is easy to clean. And the properties of glass do not disappear over time. It is recycled as much as possible, whether by ordinary consumers, professionals, or groups wishing to protect the environment. Tip: If professionals are reusing it, they need to choose glass packaging designed for this type of use. Also, to avoid scratching the primer of the glass, try to avoid excessive abrasion (e.g. steel wool balls, green-faced sponges) when cleaning.

In conclusion, the role of glass in food processing and preservation is obvious, and its advantages mainly include stability, safety, aesthetics, environmental protection, and reusability. These characteristics give glass packaging unique advantages and broad application prospects in the food field.
