With the popularization of the concept of healthy living, more and more consumers are beginning to pay attention to the material safety and performance of food containers. High borosilicate glass food containers have gradually become a popular choice in the market due to their excellent characteristics such as high temperature resistance, chemical corrosion resistance, safety and non-toxicity. So, facing a wide range of high borosilicate glass food containers, how should consumers choose scientifically? This article will comprehensively analyze the key points of purchasing high borosilicate glass food containers from multiple aspects such as material characteristics, design structure, usage requirements and brand guarantee, so as to help you buy with peace of mind and use with confidence.
1. Basic characteristics and advantages of high borosilicate glass containers
High borosilicate glass, called "Borosilicate Glass" in English, is a silicate glass containing a high boron element. Its thermal expansion coefficient is extremely low, about 1/3 of that of ordinary glass, so it has excellent heat shock resistance. Common high borosilicate glass is used for experimental utensils, lamps, optical equipment and food containers.
Advantages of high borosilicate glass food containers
High temperature and low temperature resistance: It can be directly taken out of the refrigerator and heated in a microwave oven or oven, and the temperature range is usually between -40℃ and +500℃.
Safe, non-toxic and tasteless: does not contain harmful substances, avoids food contamination, and is not easy to absorb odors or pigments.
Strong chemical corrosion resistance: resistant to acid and alkali corrosion, not easily corroded by food ingredients such as juice and oil.
Environmentally friendly and recyclable: can be used multiple times and easy to recycle, in line with the concept of green environmental protection.
Easy to clean: the surface is smooth and not easy to be stained, and it is easy to clean.
2. Key factors for purchasing high borosilicate glass food containers
Material purity: high-quality high borosilicate glass containers must first ensure the purity of the material. Generally speaking, qualified high borosilicate glass should meet the 3.3 borosilicate glass standard, that is, the boron content and silicon content are strictly controlled to ensure a low thermal expansion coefficient and avoid container breakage due to temperature changes. When purchasing, you can check the product description or consult the seller to confirm whether the material is real high borosilicate glass.
Temperature resistance: The temperature resistance range of different products may vary. High-quality high borosilicate glass containers can usually withstand the test of low temperatures of -40°C and high temperatures of 500°C, which makes the container safe for both refrigerated storage and heating in microwave ovens and ovens. When purchasing, it is recommended to give priority to products marked with clear temperature resistance parameters to ensure safety during use.
Structural design: Moderate thickness: The thickness of the glass container directly affects the impact resistance and heat preservation performance. Too thin and fragile, too thick and heavy and uneven heating. The ideal thickness should achieve a balance between lightness and firmness.
Sealing: If the container has a lid, the sealing performance is very important. A good silicone seal and buckle design can prevent liquid leakage, keep food fresh, and easy to carry.
Practical shape: Choose a suitable container shape according to the usage scenario, such as square for easy storage, round for easy cleaning, and partitions for classified storage.
Capacity: Consider the capacity according to your own needs when purchasing. The commonly used capacity for households is generally between 200ml and 2000ml. The smaller capacity is suitable for small portions of food or condiments, and the larger capacity is suitable for soup and storage of leftovers.
Lid material: The material of the lid has a greater impact on the user experience. High-quality food-grade PP plastic or silicone lids are safe and non-toxic, and have good temperature resistance. Avoid choosing lids containing harmful ingredients such as BPA.
3. Choose the right borosilicate glass container according to usage requirements
Microwave heating requirements: If you often need to put food in the microwave for heating, be sure to confirm that the entire container (including the lid) is suitable for microwave use. Some plastic lids are not resistant to high temperatures and need to be removed before heating.
Refrigeration and freezing requirements: Borosilicate glass containers are very suitable for refrigeration and freezing. When purchasing, pay attention to whether the product supports freezing below -40°C to avoid glass breakage due to sudden cooling.
Portable takeaway requirements: For office workers or students, it is very important to choose a glass portable box with good sealing performance and non-leakage, which is convenient for carrying soup, rice and fruit.
Storing long-term food: Containers used for long-term storage should have good sealing and moisture-proof properties to prevent food from oxidizing and deteriorating.
4. Choose brands and certifications for borosilicate glass food containers
Choose regular brands:
There are many brands of borosilicate glass containers on the market, and regular brands are more guaranteed in material safety and quality control. Well-known brands often provide detailed product test reports and after-sales services.
Pay attention to product certification:
Food safety certification: such as FDA, LFGB and other international food contact safety standards certification.
Environmental certification: The marked container is recyclable and harmless to the environment.
Quality certification: ISO, SGS and other third-party authoritative organizations test and certification to ensure that the material and manufacturing process meet the standards.
5. Maintenance and precautions of high borosilicate glass food containers
Although high borosilicate glass is heat-resistant and cold-resistant, it is still necessary to pay attention to daily use:
Avoid sudden cold and heat: avoid putting the container directly from high temperature into the refrigerator, or from the refrigerator directly into the oven.
Prevent falling impact: After all, glass is fragile, avoid collision and falling.
Reasonable cleaning: Avoid using hard steel wool for cleaning, soft sponge and neutral detergent are recommended.
Check the sealing ring regularly: Replace the sealing ring in time after aging to maintain the sealing effect.
High borosilicate glass food containers have become an indispensable healthy food storage tool in modern kitchens with their unique material advantages. When purchasing, consumers should consider material purity, temperature resistance, structural design, usage requirements, brand assurance and other aspects to ensure that they buy safe, practical and durable high-quality products. At the same time, proper use and maintenance can also extend the life of the container and ensure food safety. I hope that the detailed introduction in this article can help you easily choose a satisfactory high borosilicate glass food container to make your kitchen life healthier and more convenient.
