Tervis plastic products are BPA-free
Tervis is an American manufacturer of double-walled, insulated tumblers. The company was founded in 1946 and originally sold innovative plastic tumblers as an alternative to single-use products, with better insulation properties. Tervis products are known for their durability and insulation, which keeps beverages hot or cold for extended periods.
In the past, Tervis tumblers were made from polycarbonate plastic, which falls under the "'Other Plastics'" category with a code of 7. This type of plastic includes Bisphenol A (BPA), which has been a concern for health and safety. While some studies have raised concerns about the potential health risks associated with BPA, government and scientific bodies worldwide have examined the evidence, concluding that BPA exposure from polycarbonate products does not pose a risk to human health.
However, Tervis has demonstrated its commitment to product reliability and safety by transitioning to a new generation polymer that is BPA-free. This change was implemented across their entire line of products, including tumblers, mugs, water bottles, wine glasses, and sippy cups, with the process beginning in 2009 and completing in January 2011. The new polymer not only eliminates BPA but also maintains the company's quality standards.
Tervis takes sustainability seriously and has partnered with organisations like prAna to eliminate single-use plastic and virgin forest fiber from their packaging. They also reuse and recycle packaging materials, achieving an impressive 84% recycle rate. Additionally, Tervis participates in company-wide beach cleanups and recycles returned, damaged, and scrapped materials into new products, reflecting their dedication to keeping oceans and the environment clean.
In summary, while Tervis products were previously made with polycarbonate plastic containing BPA, the company has proactively addressed health concerns by transitioning to a new generation polymer that is completely BPA-free. This commitment to safety and sustainability ensures that Tervis customers can confidently enjoy their durable and environmentally-conscious products.

Tervis plastic products are durable
Tervis plastic products are highly durable. The company was founded in 1946 by John C. Winslow, who sold an innovative plastic tumbler with superior insulation properties from dock to dock. Over time, it became a tradition to have a Tervis tumbler on boats. The Tervis Tumbler Company was incorporated in 1967 and has since expanded its product line to include mugs, water bottles, wine glasses, and sippy cups, all with the same durable construction.
The durability of Tervis products is attributed to their double-walled insulation design. This design involves inserting a liner inside an outer shell, creating a layer of air between them, which are then permanently fused together. The double-wall insulation reduces condensation and keeps beverages at the desired temperature for extended periods.
Tervis products are made from polycarbonate, identified as code 7 in the Plastic Coding System introduced by the Society of the Plastics Industry, Inc. (SPI) in 1988. This coding system simplifies the sorting and recycling of plastic bottles and containers but does not indicate health and safety concerns. Tervis has stated that they are committed to delivering safe and durable products and continuously seek improvements in their materials.
In 2009, Tervis began transitioning to a new generation polymer that eliminated a step in the manufacturing process while maintaining quality standards. By January 2011, the company had completed the transition to this new polymer for all its drinkware products, ensuring they were free from Bisphenol A (BPA). Tervis also partners with organisations like prAna to eliminate single-use plastic and virgin forest fiber from their packaging, further demonstrating their commitment to sustainability and the safety of their customers.
The durability of Tervis plastic products is evident in their long-standing popularity and the company's commitment to continuous improvement and sustainability.

Tervis plastic products are safe to drink from
Tervis subjects its drinkware to extensive testing by independent testing facilities to ensure that its products exceed the strictest safety requirements of the FDA. In 2009, the company began transitioning to a new generation polymer that does not contain Bisphenol A (BPA). As of January 2011, Tervis completed the transition of its entire line of products to this new polymer.
While there have been concerns about the safety of BPA, Tervis states that it is committed to the health and safety of its customers and would not offer products that it feels would pose a health risk. The company has studied the reports and assessments conducted by various government and scientific bodies worldwide, which support the conclusion that BPA is not a risk to human health at the extremely low levels to which people might be exposed from using products made from polycarbonate.
In addition to their commitment to safety, Tervis is also dedicated to sustainability. The company partners with marine research labs, recycles its products into other post-consumer goods, and conducts company-wide beach cleanups to protect the oceans and reduce landfill waste. Tervis has also committed to eliminating single-use plastic and virgin forest fiber from its packaging and supply chain.
Overall, Tervis plastic products are safe to drink from, and the company prioritizes both the safety and sustainability of its products to protect its customers and the environment.

Tervis plastic products are double-walled and insulated
Tervis is an American manufacturer of plastic drinkware, including tumblers, mugs, water bottles, wine glasses, and sippy cups. Tervis plastic products are unique in that they are double-walled and insulated. This design feature is not just for show, but serves a practical purpose.
The double-wall insulation is created by inserting a liner inside an outer shell, leaving a layer of air between them. The two layers are then permanently fused together. This insulation helps to maintain the temperature of beverages, keeping drinks hot or cold for longer than non-insulated cups and glasses. The insulation also reduces condensation, preventing the outer surface of the tumbler from becoming too hot or cold, and avoiding the formation of water droplets on the outside of the cup.
The original Tervis tumbler technology was developed in Detroit, Michigan, in 1946 by two engineers, Frank Cotter and G. Howlett Davis. The name 'Tervis' was derived from the last three letters of their surnames. John C. Winslow purchased the Tervis product rights in the 1940s, and the Tervis Tumbler Company was officially incorporated in 1967. Winslow sold the innovative tumblers dock to dock, and having a Tervis tumbler on one's boat became a tradition.
Tervis products are made from polycarbonate, which falls under the 'Other Plastics' category with a code of 7. While some older Tervis products contained Bisphenol A (BPA), the company transitioned to a new generation polymer in 2011, eliminating BPA from their entire line of products. This change upholds Tervis' commitment to delivering high-quality, durable, and safe drinkware that meets or exceeds strict FDA safety requirements.
