Sanitary and safe materials are harmless to the human body, such as PC materials, PE materials and PP materials. The more common plastic fresh-keeping box material is PP material.
2. Transparency: Plastic fresh-keeping boxes are generally made of transparent or translucent materials. In this way, you can easily confirm the items in the box without opening the box when using it.
3. Appearance: Plastic fresh-keeping boxes with excellent quality have a glossy appearance, beautiful design and no burrs.
4. Heat resistance: Plastic fresh-keeping boxes have higher requirements for heat resistance, will not deform in high-temperature water, and can even be sterilized in boiling water.
5. Durability: Plastic fresh-keeping boxes must have excellent impact resistance, are not easy to break under heavy pressure or impact, and will not leave scratches.
6. Sealing: This is the first consideration when choosing a plastic fresh-keeping box. Although the sealing methods of products from different brands are different, excellent sealing is a necessary condition for the long-term preservation of food.
7. Fresh-keeping: The international standard for sealing is based on moisture permeability test. High-quality plastic fresh-keeping boxes have a moisture permeability 200 times lower than similar products, which can keep things fresh for a longer time.
8. Space saving: With reasonable design, plastic fresh-keeping boxes of various sizes can be placed and combined in an orderly manner, keeping them neat and saving space.
9. Microwave heating: Food can be heated directly in the microwave, which is more convenient.

2. Prevent food from losing its original freshness during storage;
3. Isolate air to prevent food from oxidation (infection);
Different shapes store different things, which is more convenient to use. In addition to the common square, rectangular, and round shapes, there are also sets designed for picnics, etc., making life simpler and more convenient.
Square plastic fresh-keeping box: Excellent sealing performance, suitable for storing food, can prevent odors in the refrigerator, suitable for storing various condiments, leftovers, leftover canned food, fruits, and vegetables. It is convenient to put in refrigerators, freezers, microwave ovens, and can also be used for other purposes.
Rectangular plastic fresh-keeping box: suitable for storing bacon and meat. Because there is a water receiving plate, it is easy to store food with moisture. Large-capacity rectangular plastic fresh-keeping box is suitable for storing fruits, vegetables, seafood, etc.
Round plastic fresh-keeping box: suitable for long-term storage of various condiments, canned fruits, grains, nuts, tea and other foods, and convenient for use in refrigerators, freezers, and microwave ovens. The oblong design is suitable for storing beverages, children's milk and various grains, nuts and tea during outdoor activities.
High-tube plastic fresh-keeping box: suitable for storing long-shaped foods such as noodles and cucumbers. Since the height of the high-tube plastic fresh-keeping box is higher than that of ordinary plastic fresh-keeping boxes, the processing technology has high requirements for mold size and mold removal. Therefore, there are not many manufacturers on the market that can produce high-tube plastic fresh-keeping boxes, and the products are relatively few.
¢±Ordinary plastic plastic fresh-keeping boxes cannot be placed in microwave ovens and ovens, because plastics will produce substances harmful to the human body at high temperatures. If you often use microwave ovens for cooking, it is best to choose plastic fresh-keeping boxes made of polycarbonate (PC); if you use a high temperature of about 70 degrees for continuous sterilization and washing, please do not exceed 20 to 30 minutes. The high-heat part of ordinary dishwashers is at the bottom, and the upper part is relatively indirectly heated, so it is better to wash them in the upper part of the dishwasher. Although plastic products made of polypropylene have high heat resistance, if they are heated for a long time, the products will deform and be elongated. Therefore, after washing, if you want to use it immediately, please soak the plastic fresh-keeping box in cold water before using it. This is a good way to prevent deformation. In addition, tempered glass plastic fresh-keeping boxes may explode when encountering extreme cold and extreme heat.
¢² Different foods have different storage times. Do not rely solely on the sealing ability of plastic fresh-keeping boxes. They should be eaten as soon as possible. PP (polypropylene) plastic fresh-keeping boxes can be heated for a short time when used in a microwave oven, but they cannot be used as cooking containers in a microwave oven. (When heating and thawing for a short time, the time should not exceed 3 minutes.)
¢³ When putting it in a microwave oven, you must first loosen the lid joint device before using it. If the lid is locked before use, the plastic fresh-keeping box may deform or burst due to pressure. When used in a microwave oven, if the food contains a lot of oil and sugar, the plastic fresh-keeping box may deform when the temperature rises rapidly.
¢´ When cleaning the plastic fresh-keeping box, use a softer sponge instead of a hard dishcloth to avoid scratches that may discolor the plastic fresh-keeping box. When cleaning the silicone resin gasket between the lid and the container, do not push or pull it hard, otherwise it may break or lengthen.
¢µ Hot food will cause the air to expand, reducing the sealing performance of the plastic fresh-keeping box, so you should wait until the food cools down before storing it. The bubbles in carbonated drinks (soda, cola, etc.) will cause the plastic fresh-keeping box to lose its sealing ability, so do not store it in a plastic fresh-keeping box.
