Storage Jar Industry
Glass food storage jars can be used to store all kinds of food
For dry goods, such as rice, beans, nuts, etc., glass storage jars can effectively prevent moisture, pests and oxidation. Its sealing performance keeps the environment inside the jar dry, extending the shelf life of dry goods. For example, nuts are rich in oil and are easily oxidized and deteriorated in the air. Glass storage jars can isolate them from the outside air and maintain the freshness and taste of nuts.
For pickled foods, such as kimchi and pickles, the chemical stability of glass ensures that it will not react with the acidic substances or salt in the pickled foods. Glass storage jars can maintain the pickling environment well, allowing kimchi and other foods to ferment normally during the pickling process and maintain their flavor during storage.
When storing sauces, such as ketchup and jam, the transparency of glass food storage jars allows users to intuitively see the remaining amount of sauce inside, while preventing the sauce from being contaminated by the outside world and maintaining its original color and flavor.
Glass has extremely low gas permeability and can block the entry and exit of gases such as oxygen and carbon dioxide. This is essential for preventing food from oxidizing and mildewing. At the same time, the sealing design of glass storage jars, such as lids with rubber sealing rings, can further prevent the entry of air and moisture, thereby achieving a good preservation effect.
There are mainly the following types of glass storage jar mouths:
I. Screw mouth
- Coarse thread
- Features: The thread spacing is larger and the texture is coarse. This type of screw mouth is more common on glass storage jars, especially those with larger capacity. The advantage of coarse thread is that it is easier to use force when opening and closing, which is suitable for storing some heavier or frequently used items, such as dry goods such as rice and beans. In addition, coarse thread can provide a better sealing effect to prevent outside air, moisture and impurities from entering the jar.
- Fine thread
- Features: The thread is fine and dense. Fine thread screw mouths are often used in glass storage jars with smaller capacity or for storing delicate items, such as spices, high-grade tea, etc. Fine threads can provide a tighter seal, which is very effective for preventing small particles from leaking or storing volatile items.
II. Bayonet
- Single bayonet
- Features: This jar mouth is connected to the lid through a simple buckle structure. The single bayonet has a simple structure and is easy to open and close. It is often used in some small glass storage jars, such as storing small doses of tasting sauces or medicines. However, its sealing effect may be slightly weaker than that of the spiral mouth.
- Double bayonet or multi-bayonet
- Features: There are two or more buckle structures. This type of bayonet has a better sealing effect than the single bayonet and can provide a more stable seal. It is suitable for storing some foods that have high sealing requirements but need to be easy to access, such as pickled foods or semi-solid sauces.
Glass is a non-toxic, odorless material that does not release harmful substances when storing food like some plastic containers. This makes glass food storage jars safer and more reliable when storing all kinds of food, meeting people’s requirements for healthy food storage.
