Vacuum food containers are usually made of different materials, such as plastic, glass, and stainless steel. Each material has its advantages and disadvantages, so it's important to choose one that suits your needs.<\/p>\n

Plastic vacuum food containers: Plastic containers are generally lightweight and easy to carry and store. They also have good impact and corrosion resistance. However, some cheap plastic containers may release harmful substances, so it is important to choose high-quality food-grade plastic containers.<\/p>\n

Glass vacuum food containers: Glass containers are generally more durable and won't stain or smell from food. They are also easier to clean and maintain. However, glass containers are heavy, fragile, and not suitable for carrying and storing large amounts of food.<\/p>\n

Stainless steel vacuum food containers: Stainless steel containers have excellent corrosion resistance and high-temperature resistance. They also don't release harmful substances and are ideal for storing acidic foods. However, stainless steel containers are heavier and more expensive.<\/p>\n

2. Container size and shape<\/h2>\n

Choosing the right container size and shape is key to ensuring effective food storage. Here are some considerations:<\/p>\n

Vacuum food container size: The size of the container should be chosen based on the needs of the individual or family. If you frequently need to store large amounts of food, choosing a larger container may be more appropriate. Additionally, the height and width of the container need to be considered to ensure it is suitable for the type of food being stored.<\/p>\n

Vacuum food container shape: The shape of the container is also an important factor. Some containers have a square or rectangular shape, suitable for storing bulk foods such as cuts of meat or vegetables. While other containers have a round or oval shape and are suitable for storing liquid or semi-solid food.<\/p>\n

Stacking and Storage: It's also important to consider the container's stacking and storage capabilities. Some containers have a stackable design to save storage space. In addition, the tightness of the container also needs to be considered to ensure that the food does not leak or become contaminated.<\/p>\n

3. Sealing performance<\/h2>\n

The sealing performance of vacuum food containers is the key to ensuring that the vacuum environment is not destroyed. Here are some sealing performance considerations:<\/p>\n

Sealing device: The sealing device of the container should have good sealing performance to ensure that the inside of the container is isolated from the outside world. Some containers have elastic seals or silicone gaskets that provide a better seal.<\/p>\n

Air extraction device: Some vacuum food containers are equipped with an air extraction device, which can easily extract the air inside the container. These extraction devices can be manual or electric. It is very important to choose an extraction device that suits your usage habits and needs.<\/p>\n

Sealing durability: The sealing performance of the container should be durable and stable to ensure that the vacuum environment will not be destroyed. Some containers have a self-sealing feature that automatically closes the seal after pumping.<\/p>\n

4. Brand and price<\/h2>\n

Choosing a well-known brand of vacuum food containers ensures product quality and performance. These brands usually have good word-of-mouth and customer reviews. However, branded products are usually more expensive. If your budget is limited, you can also choose some cost-effective products.<\/p>\n
