Plastic Tervis Products And Microwaving: A Safety Check

When it comes to Tervis tumblers and mugs, it is important to know the materials they are made of to determine if they are microwave-safe. Tervis products can be made with plastic or metal materials.

  • Plastic Tervis tumblers, plastic water bottles, and wine glasses are usually microwave-safe, allowing you to heat up your beverages or food safely in these products.

Understanding Tervis Labels: Microwave-Safe Or Not?

The labels on the bottom of Tervis products provide clear instructions for microwaving. Understanding these labels is important for safe microwave use and avoiding damage.

The “Microwave Safe” label indicates that the Tervis can be microwaved without its lid for up to 30 seconds. This label assures you that the product is safe for short heating periods.

The “Microwave When Full” label suggests that the Tervis can only be microwaved when it is filled with liquid up to one inch from the top. This label is used for products with design elements or metal accents that may be affected by microwave radiation.

The “Do Not Microwave” label clearly states that the Tervis item should not be microwaved. This cautionary label is likely present on products that have metal components or unsuitable materials.

Always remember to remove the lid before microwaving, regardless of the label indication. This allows heat to escape and prevents potential issues.

Microwaving Tervis Cups: Considerations And Limitations

Most Tervis cups made after 2011, which are made with the new generation polymer, can be safely microwaved for up to 30 seconds. However, it is important to be mindful of any metal accents or design elements on the Tervis cup, as these may affect its microwave compatibility.

When in doubt, it is always best to err on the side of caution. If you are uncertain whether a specific Tervis cup is safe to microwave, it is advisable to reach out to the manufacturer for clarification. They can provide you with accurate information and guidance based on the specific Tervis product in question.

Tervis tumblers and mugs can be made with either plastic or metal materials. Plastic Tervis products are usually microwave-safe, while stainless steel items are not. Determining if a Tervis product is microwave-safe can be done by checking the company’s website or scanning the product description. Additionally, examining the bottom of the Tervis for specific labels is essential to know if it is safe to microwave. However, it is crucial to pay attention to any metal accents or design elements that may affect microwave compatibility. By following these guidelines and precautions, you can safely enjoy your Tervis products while using the microwave.
