Why choose borosilicate glass containers instead of plastic containers?

In modern life, containers are everywhere. Whether it is kitchen storage, food takeout, drinking cups, or laboratory utensils and maternal and child products, the material of the container is directly related to the user experience and health and safety. At present, there are two main types of materials popular on the market: plastic containers and glass containers. In particular, "high borosilicate glass containers" have gradually become the first choice to replace plastic containers due to their superior performance. So, why do more and more people choose high borosilicate glass containers instead of plastic containers among many options? This article will analyze in depth from multiple angles.

1. Material advantages of high borosilicate glass

High temperature resistance and not easy to burst: high borosilicate glass is a special glass containing silicon dioxide and boron trioxide, with an extremely low thermal expansion coefficient and a heat-resistant temperature difference of up to 150°C or even above. This means that it can be directly put from the refrigerator into a microwave, oven or electric stove for heating, without being as easy to burst or deform as ordinary glass or plastic.

In contrast, most plastic containers soften, melt, and even release toxic substances (such as BPA or phthalates) at high temperatures, posing potential health risks.

No harmful chemical ingredients: borosilicate glass is natural and environmentally friendly, and does not contain any heavy metals, plasticizers or harmful additives. It does not release any harmful substances when exposed to heat or in contact with acidic and alkaline substances, so it is widely used in maternal and child products and medical containers.

Many plastic products (even if they are labeled "food grade") are difficult to completely eliminate harmful residues, especially when exposed to high temperatures, strong acids or alcohol, which are more likely to release trace chemical components, and long-term use may have an impact on the human body.

Not easy to change color or absorb odors: The surface of borosilicate glass is smooth and dense, and it is not easy to absorb liquids, grease or odors. Even if it is used to hold heavy-tasting foods such as curry and soy sauce, it will not stain or leave odors. The surface of plastic containers is mostly porous, which is very easy to absorb food odors and is not easy to clean. After long-term use, it will turn yellow, smelly, and discolored.

2. Better use experience

Aesthetics and transparency: borosilicate glass containers have excellent optical transparency, which is transparent and bright. Not only can people see the state of the food in the container at a glance, but also enhance the overall beauty of life. Especially in the fields of beverage bottles, food boxes, storage jars, etc., glass containers are not only practical, but also have high visual beauty.

Plastic containers are prone to yellowing and scratching over time, affecting the appearance, and the sense of grade is far inferior to glass.

Easier to clean: The smooth surface of glass makes it difficult for oil and residue to adhere, and it can generally be restored to a new state by washing with warm water + detergent. However, due to the insufficient surface structure of plastic containers, it is easy to breed bacteria or produce scratches, and it is difficult to clean thoroughly over time.

Can be used in a variety of heating equipment: high borosilicate glass can be used safely in microwave ovens, ovens, and dishwashers. It is not easy to break due to thermal expansion and contraction, and is suitable for a variety of needs in modern kitchens. However, most plastic containers are extremely sensitive to high temperatures and cannot be put into ovens. Some cannot even be put into microwave ovens or dishwashers, which limits the use scenarios.

3. Environmental protection and sustainability

With the increase of global environmental awareness, people pay more attention to sustainable consumption. High borosilicate glass containers are the representative of green consumption.

Reusable and long life: High borosilicate glass containers can be used repeatedly for a long time under correct use, and their service life is often several times that of plastic, and can even reach more than 5 years without deformation or deterioration. Plastic containers are prone to aging, cracking, and discoloration, and often need to be replaced, generating a large amount of plastic waste.

Recyclable and degradable: High borosilicate glass is a 100% recyclable material that will not pollute soil and water bodies, and is an ideal choice for achieving "zero waste life". The degradation cycle of plastic is very long, and some can reach hundreds of years, which not only causes environmental burdens, but also harms wildlife ecology.

Reduce the use of disposable plastics: Choosing high borosilicate glass containers can greatly reduce the frequency of use of disposable plastic bags, plastic cups, and takeaway plastic boxes, and contribute to environmental protection. It is especially suitable for daily portable products such as coffee cups, water bottles, and lunch boxes.

4. Health and safety are key considerations

Modern consumers are paying more and more attention to health issues, especially the selection of food containers for mothers and babies, the elderly, and special groups must be cautious. The food-grade safety performance of high borosilicate glass makes it the first choice for families:

Baby food boxes and baby bottles: Many maternal and child brands have fully adopted high borosilicate glass to replace traditional plastic baby bottles.

Medical equipment and laboratory utensils: Laboratory beakers, test tubes, medicine bottles, etc. are almost all made of high borosilicate glass because of its high chemical stability.

Health pots and glasses: Long-term contact with hot water, tea, and Chinese medicinal materials to avoid health risks from plastic precipitation.

Plastic products have many health concerns, especially when heated, in contact with oils or acidic substances, the risk of chemical migration increases.

5. Cost-effective choice

Although the initial cost of high borosilicate glass is slightly higher than that of plastic containers, it is more cost-effective in the long run:

One-time investment, can be used for many years;

Reduce replacement frequency and save costs;

Can be used in multiple scenarios, with storage and heating functions;

Beautiful and durable, improve the quality of the family.

In contrast, plastic containers are used frequently but replaced frequently. Repeated purchases, pollution of the environment, and health effects are not cost-effective or environmentally friendly.

6. Precautions for use

Although borosilicate glass has excellent performance, you still need to pay attention to the following points to extend its service life:

Avoid strong impact. Although it is more resistant to falling, it is still made of glass;

Avoid extreme temperature changes, such as heating immediately after taking it out of the refrigerator;

Use with a silicone protective cover to further improve the shock resistance;

If there are fine cracks or bump marks, it is recommended to replace it to prevent the cracks from getting worse.

In terms of environmental protection, health, safety, aesthetics and economy, borosilicate glass containers are undoubtedly a wiser choice in modern life. It not only solves the health concerns brought by plastic containers, but also responds to the concept of environmental protection and improves the quality of life. In the future, as people's requirements for quality of life increase, choosing borosilicate glass containers will no longer be an "alternative solution", but will become a symbol of the mainstream lifestyle.
