Latest company blog about Thermoguard Cups Launch with Ecofriendly Duallayer Insulation

Consumers who have struggled with hot beverage containers that transfer too much heat or require additional sleeves may find a solution in Dart Container's ThermoGuard® line of double-walled paper cups. The product line utilizes proprietary ThermoTouch™ technology to deliver both superior insulation and environmental benefits.

Innovative Insulation Eliminates Need for Sleeves

The ThermoGuard® series features a patented double-wall design that creates an air barrier between the cup's inner and outer layers. This construction prevents heat transfer from hot liquids to the exterior surface, allowing comfortable handling without secondary insulating sleeves. The ThermoTouch™ technology demonstrates thoughtful ergonomic design while reducing potential waste from disposable sleeves.

Extended Temperature Retention and Leak Prevention

Beyond surface temperature control, the dual-layer architecture provides enhanced thermal retention, maintaining optimal drinking temperatures longer than conventional single-wall cups. The interior moisture-resistant lining prevents liquid penetration and cup deformation, minimizing spill risks during consumption. These characteristics make the product particularly suitable for foodservice establishments serving hot beverages.

Environmental Commitments Through ProPlanet™ Certification

Dart Container has incorporated sustainability measures into the ThermoGuard® line, which carries ProPlanet™ certification indicating a minimum 75% renewable material composition. The certification recognizes environmentally responsible material sourcing and manufacturing processes throughout the product lifecycle.

Additional ecological features include:

  • Recyclability in appropriate waste management systems
  • SFI® (Sustainable Forestry Initiative) certification for responsibly sourced paper materials
  • Domestic U.S. production reducing transportation-related emissions for certain products
