2. Tritan™ Copolyester (Safest Plastic)

Tritan™ Plastic was originally developed for baby bottles and children’s products because it is a non-toxic, shatter-resistant material, making it ideal for young users. It contains no harmful substances or plasticizers, such as Bisphenol A (BPA). As a result, Tritan has expanded into many other products and applications.

Water bottles made from this material are not only lightweight and durable but also easy to handle and dishwasher-safe. They serve as an ideal alternative to single-use plastic bottles. These reusable bottles are perfect for use in offices, sports, outdoor activities, playgrounds, homes, events, or even medical and educational settings.

Chemical Properties:

• 0% BPA, BPS, BPF
• Hydrolytic stability >100°C (212°F)
• Impact strength: 910 J/m

Use Cases:

• Kids’ bottles (CPSIA certified)
• Sports squeeze bottles (shatter-resistant)
• Transparent designer bottles (>90% clarity)

3. Borosilicate Glass (Pure Taste Preservation)

Borosilicate glass was initially developed for laboratory use and has since gained increasing adoption across medical and industrial applications worldwide. In these fields where sterility and hygiene are critical, borosilicate glass has become the ideal choice due to its unique properties and advantages.

This specialized glass is BPA-free, contains no harmful substances, and is chemically resistant. It releases no compounds into liquids, food, or the human body. As a result, it is now widely used in everyday products—particularly for manufacturing bottles and drinking vessels.

5. Copper (Antimicrobial Luxury)

Copper water bottles (especially those made of pure copper or copper alloys) are highly valued in certain markets and cultures due to their unique health benefits, functional properties, and aesthetic appeal.

In Ayurvedic medicine and various traditional practices, copper is believed to balance body constitution, enhance metabolism, and provide antioxidant effects. Storing water overnight in a copper bottle (known as “Tamra Jal”) is thought to release trace amounts of copper ions, which may aid digestion and boost immunity.

Copper bottles also boast a vintage, luxurious handcrafted appeal, developing a distinctive patina over time (which can be restored using lemon juice or baking soda). This makes them ideal as artisanal pieces or premium gifts, often seen in high-end home décor, yoga communities, and traditional ceremonial settings.

Antibacterial Performance:

• 99.9% kill rate (ISO 22196)
• Natural oxidation patina
• Hand-hammered textures

Premium Clients:
