Material affects taste, durability, temperature control, and environmental impact.
Material Comparison Guide:
| Material | Best For | Key Advantages | Considerations |
|---|---|---|---|
| Stainless Steel | Active users, temperature control | Excellent insulation, durable, no taste transfer | Heavier, can dent, higher cost |
| Glass | Home/office, taste purists | No chemical leaching, easy to clean, eco-friendly | Fragile, requires protective sleeve, heavier |
| Tritan Plastic | Lightweight needs, budget-friendly | Lightweight, durable, BPA-free | Less insulation, can absorb odors over time |
| Silicone | Travel, space-saving | Collapsible, extremely lightweight, flexible | Less durable, can retain folded shape |
| Aluminum | Lightweight active use | Very lightweight, affordable | Usually lined (check lining safety), dents easily |
Health & Safety Checklist:
✅ BPA-free, phthalate-free certification
✅ Food-grade materials clearly labeled
✅ Non-toxic coatings (if applicable)
✅ Easy-to-clean surfaces that resist bacteria
✅ Reputable manufacturer with transparency
Environmental Considerations:
- Recycled material content
- End-of-life recyclability
- Manufacturing sustainability
- Durability (long lifespan reduces waste)
