Likewise, is it safe to boil plastic?
Yes, boiling water in plastic will introduce toxic chemicals into the water. But these same toxic chemicals are also introduced into the water at room temperature, just at a much slower rate, and no one, including the FDA, is up in arms about it as it just isn't a concern.
Similarly, can you put boiling water in Rubbermaid container? boiling water will definitely not melt your rubbermaid pitcher. Boiling sugar would, or maybe super hot oil, but but certainly not plain old water. If you are concerned, you could always just use a glass pitcher. Just make sure you don't throw something very cold in the pitcher directly afterwards.
Also asked, what happens if you boil plastic?
Plastics do not melt in boiling water however they do soften and form weird shapes. All materials which have Polyethylene (PE) and Polypropylene (PP) soften but materials such as ABS, PS, PC etc are strong even in boiling water. Most of the bottles we see in market are either PP or PE which soften with hot water.
Is Tupperware heat safe?
Tupperware is also generally dishwasher and freezer safe. These containers are convenient, durable and easy to care for. If you're comfortable with microwaving Tupperware or any other plastic containers, you can reduce the risk of damage and staining by stirring the product frequently.
