Advantages of Using Glass Food Storage Containers
No Chemicals
Glass is the new wave of the chemical-free movement. It doesn’t have dyes or chemicals like BPAs, BPSs, or lead that could leach into your food. Glass can handle high heat, including the microwave, without ever having to worry about warping or leaching chemicals. It is a safer alternative to the increasingly common plastic storage containers.
Recyclable
Glass is the perfect option for an eco-friendly mind. Plastics end up in landfills, and in our water supply, leaching out chemicals and toxins as the sun and ozone slowly break them down. Glass is 100% recyclable. It is eco-friendly and responsible, having many advantages over plastic.
Easily Cleaned
Glass is better than plastic, not only because it lasts longer, but because it is so easy to clean. You never have to worry about foods staining the sides or making your tupperware stink. Plastic tupperware has this problem because plastics naturally absorb colors, odors, and flavors. But glass tupperware is always clean and will never absorb the colors or odors of your food because it is non-porous.
Flavor Protection
Over time plastic tupperware can absorb flavors and smells of the food that sits inside it. This means that the next meal you put in that container could absorb those same old flavors and odors, ruining your good meal. The advantage of glass is that this never happens. It will never absorb and odors or flavors of your food, no matter how long they stay in the container.
Things to Consider Before Buying Glass Tupperware
Type of Glass
The glass you choose for your food storage containers matters. The glass that is used will determine the strength of the container, as well as whether or not it can handle being used in the oven or the microwave.
It is imperative that you choose glass containers that can handle your needs. Some types of glass are not as strong or thermal shock resistant as others so make sure that you do your research and choose wisely.
If your glass containers just store food, then any old container will do. But if there are going to be storing food in the freezer or cooking meals in the oven, they’ll you’ll want something a bit more robust.
Strength of the Seal
The seal on your glass food storage container is essential. If it is a container that is used in your refrigerator, then a pressure or friction seal might do the job, but if this glass tupperware is ever going to go in a lunchbox or a backpack, then you want to make sure that you have something with an airtight seal so that it doesn’t spill.
Clamp
Much like the seal the clamp is an important design feature. Not all tupperware has clamps. Clamps are the wings on the sides of the lid. They hook under edge on the body of the tupperware and hold the lid firmly in place. Like the seal, a strong form-fitting clamp is essential for any tupperware that is going to leave the house. You don’t want your meal accidentally opening up in your purse or bookbag.
Heat Management
You may think of these glass containers only as a receptacle to hold food. But many people reheat their food in the microwave or the oven while it is still in the container. In this case, you need to make sure that your glass tupperware can handle high heat. This is when the structure and material of the glass come into play. You want a glass that is high heat and microwave safe.
For this, we recommend borosilicate glass. Not only is borosilicate on of the strongest, most durable glasses out there, but it is also one of the most thermal shock resistant.
Thermal shock is what happens when glass goes from one extreme to another, usually causing it to crack under stress. Borosilicate glass, however, is lab-grade quality, so it is extremely resistant to temperature changes.
This is a vital feature to have in a glass food storage container that will frequently be going form the refrigerator or freezer straight into the oven or microwave for reheating.
Eco-Friendly
Glass tupperware is naturally eco-friendly and environmentally safe. But if you really want to check all of the environmental boxes, then you may want to look into a glass container with a bamboo lid. Perhaps considering what the seals and clamps are made of, to ensure that every piece of your tupperware is biodegradable or recyclable.
