Food-Safe TPE Materials for Nutrition Bottles

Nutrition bottles are specialized containers to hold liquids for hydration, wellness beverages, or infant formula. Because they come into direct contact with products for human consumption, manufacturers must use food-safe materials and ensure the bottles are sturdy enough to withstand handling, dispensing, and repeated use across different settings and consumers. KRAIBURG TPE, a global manufacturer of thermoplastic elastomers (TPEs) and customized solutions for various industries, addresses these needs with its THERMOLAST® K series TPE compounds, specifically designed for nutrition bottle applications. This series enhances the functionality of nutrition bottle solutions by imparting the properties necessary for functional reliability and long-term performance, while assisting manufacturers with efficient processing, regulatory compliance, and consistent product quality.

Soft touch feels and consistent form
THERMOLAST® K series in nutrition bottle applications exhibits an optimized compression set, ensuring that components such as sealing cups, bottle caps, and flexible grips retain their form and usability even with frequent use.

Seamless part integration and multi-component efficiency
THERMOLAST® K series demonstrates excellent adhesion to polypropylene (PP), a commonly used polymer in nutrition bottles, allowing seamless integration of soft functional elements with rigid bottle components. Its excellent processability in multi-component injection molding further improves manufacturing efficiency and scalability, making it a significant advantage in production. The materials also facilitate optimized demolding, in-process recycling, and compatibility with HDPE and PP recycling, making them practical for sustainable production.

Versatility in design and appearance 
THERMOLAST® K series is colorable and available in translucent formulations, providing clear visibility of liquid levels and permitting aesthetic customization. The smooth touch material features low surface friction and abrasion resistance, making these nutrition bottle materials suitable for a wide range of bottle components, including sealing cups, caps, handles,and protective sleeves.

Compliance with global material standards
THERMOLAST® K series meets international food-contact compliance and standards, including Regulation (EU) No 10/2011, US FDA CFR 21, GB 4806.7-2023, MERCOSUR (GMC Res. No. 03/92, 02/12, 39/19), and EN71-3, and is also ISCC PLUS certified for material sustainability and circularity.
