In modern kitchens, vacuum glass food containers are loved by consumers for their good sealing, durability, and food safety. However, many users will find that the sealing ring does not seem to be as tight as when they were first bought after long-term use, and may even become hard, loose or cracked. So, will the sealing ring of the vacuum glass food container age? This article will discuss in depth the material, aging reasons, maintenance tips, and other aspects of the sealing ring, and help you extend the service life of the sealing ring.

1. Material of the sealing ring of the vacuum glass food container

The sealing ring is a key component for vacuum glass food containers to maintain good sealing performance. It is usually made of the following materials:

Silicone sealing ring: Food-grade silicone has become one of the main materials for vacuum glass food container sealing rings because of its high temperature resistance, low temperature resistance, good elasticity and non-deformation characteristics.

Rubber sealing ring: Compared with silicone, rubber material may become hard or brittle over time, affecting the sealing effect.

Plastic sealing ring: Some low-end products use plastic sealing rings, but because they are easy to age and not resistant to high temperatures, they are rarely used in high-quality vacuum glass food containers.

2. Reasons for aging of the sealing ring of vacuum glass food containers

Although the sealing ring of vacuum glass food containers usually has a long service life, it will still be affected by the following factors during daily use, resulting in aging or performance degradation:

High temperature effect: Frequent use of microwave ovens, dishwashers or hot water for cleaning will cause the sealing ring to be in a high temperature environment for a long time, which may accelerate the decomposition of silicone or rubber materials and gradually lose their elasticity.

Low temperature embrittlement: The sealing ring tends to harden in a low temperature environment, especially when stored in the freezer for a long time, which may cause embrittlement or even cracking.

Chemical corrosion: Some detergents contain strong alkali or strong acid components, which may corrode the silicone sealing ring, causing it to lose elasticity, or even whiten or crack.

Physical wear: Frequent disassembly and cleaning or excessive pulling of the sealing ring may cause its surface to wear and affect the sealing performance.

Grease and food residue: Long-term contact with grease or certain highly pigmented foods (such as curry, ketchup) may cause the sealing ring to discolor, soften or lose elasticity.

3. How to extend the service life of the sealing ring of vacuum glass food containers?

In order to ensure the sealing performance of the vacuum glass food container and extend the service life of the sealing ring, the following maintenance measures are recommended:

Avoid direct high temperature: Avoid exposing the vacuum glass food container to the sun for a long time or storing it in a high temperature environment (such as near the stove). If you need to use a dishwasher to wash, it is recommended to choose the low temperature mode and avoid high temperature drying.

Correct cleaning method: When cleaning the sealing ring, it is recommended to use warm water and mild detergent, and avoid using detergents containing strong alkali or strong acid such as alcohol and bleach. Dry it after washing or wipe it with a clean cotton cloth to avoid residual moisture from breeding bacteria.

Regular inspection and replacement: Regularly check whether the sealing ring is cracked, deformed or hardened. If any problems are found, it should be replaced in time.

In general, it is recommended to replace the sealing ring of the vacuum glass food container once every 1-2 years to ensure the sealing effect.

Avoid contact with grease and pigmented foods. When storing high-fat and high-pigmented foods (such as curry, sauces, etc.), it is recommended to first lay a layer of food-grade plastic film in the container to reduce direct contact with the sealing ring.

Store in a suitable environment: When not in use for a long time, the sealing ring can be removed separately and placed in a dry and ventilated place to avoid moisture and high temperature.

4. Can the sealing ring of the vacuum glass food container be purchased separately?

Many high-quality vacuum glass food container brands will provide additional sealing ring replacement options, and users can purchase sealing rings of corresponding specifications for replacement according to the model. When purchasing, it is recommended to choose original accessories to ensure sealing and matching. If you can't find original accessories, you can also choose a universal silicone sealing ring that meets food safety standards.

The sealing ring of the vacuum glass food container will indeed age, but through proper use and maintenance, its service life can be effectively extended. High temperature, low temperature, chemical corrosion, physical wear and oil pollution, and other factors will affect the performance of the sealing ring. Therefore, in daily use, you must pay attention to proper cleaning, regular inspection, and replacement of suitable sealing rings. Choosing high-quality vacuum glass food containers and matching them with good maintenance habits can not only keep the food fresh, but also enhance the overall use experience.

I hope this article can help you better understand how to maintain and extend the service life of the sealing ring of the vacuum glass food container. If you are interested in other issues related to vacuum glass containers, please leave a message to communicate!
