In modern kitchens, fresh-keeping boxes have become indispensable daily necessities. With the increasing awareness of health and environmental protection, liquid silicone fresh-keeping box has gradually been favored by consumers due to its unique material properties. However, many people still have doubts about whether this fresh-keeping box is suitable for microwave heating.High temperature resistance of liquid siliconeLiquid silicone is a polymer material with excellent temperature resistance. Normally, it can remain stable between -40℃ and 230℃, and will not release harmful substances or deform due to temperature changes. This feature makes liquid silicone products widely used in many fields such as baby bottles, baking molds, and kitchen utensils. Therefore, from the material itself, liquid silicone fresh-keeping box has good heat resistance and can withstand the high temperature environment during microwave heating.Why can it be put into the microwave?In the process of heating food in the microwave, the container needs to withstand a certain amount of heat and electromagnetic wave radiation. Ordinary plastic fresh-keeping boxes are easy to deform and release harmful chemicals such as bisphenol A at high temperatures, posing a potential threat to human health. Due to its stable chemical structure, liquid silicone fresh-keeping box will not release toxic substances when heated in a microwave oven, nor will it soften or melt due to heat. As long as the product is marked with words such as "food grade" and "microwave safe", you can safely put the liquid silicone fresh-keeping box in the microwave for heating.Matters needing attention when usingAlthough the liquid silicone fresh-keeping box can be put into the microwave, there are still some precautions to be observed during actual use. First, it is recommended to open the lid or leave a vent before heating to avoid excessive internal pressure in the sealed state, resulting in bursting or splashing. Secondly, the heating time should not be too long, especially when holding high-fat or high-sugar foods, the heating temperature and time should be properly controlled to avoid local overheating that affects the service life of the fresh-keeping box. In addition, although liquid silicone is resistant to high temperatures, it should still avoid direct contact with the inner wall of the microwave oven or other metal parts to prevent local overheating and damage.Safety performance under multiple usesIn addition to microwave heating, liquid silicone fresh-keeping box is also suitable for refrigerator refrigeration, frozen storage, dishwasher cleaning and other scenarios. This versatility makes it an ideal storage tool in modern families. Especially when food needs to be heated quickly, it can be taken directly from the refrigerator and put into the microwave without changing the container, which saves time and reduces the risk of contamination. At the same time, the flexibility and lightness of liquid silicone also make it more convenient to carry when going out, especially suitable for office workers, students and families with children.Advantages of traditional plastic fresh-keeping boxesCompared with traditional plastic fresh-keeping boxes, liquid silicone fresh-keeping boxes have advantages in safety, durability and environmental protection. Plastic products are prone to aging, yellowing and even releasing harmful substances after repeated heating, while liquid silicone is not easy to age, has stable color, and has stronger compression resistance and resilience. Even if it is folded or squeezed, it can quickly return to its original shape. More importantly, liquid silicone does not contain toxic ingredients such as BPA and phthalates, and is particularly friendly to children and pregnant women.In general, liquid silicone fresh-keeping boxes can be safely put into microwave ovens, provided that food-grade products produced by regular manufacturers are selected and the correct usage is followed. Its advantages such as high temperature resistance, non-toxic and odorless, and reusability make it a trustworthy storage tool in the modern kitchen.
