When people want a glass water bottle that is safe and can be used again and again, the quality of the material is the most important thing. Most glass bottles on the market look the same, but they are not made from the same kind of glass. We use high borosilicate glass to make our glass water bottles because we want them to last a long time, be safe, and be reliable for daily hydration.
In this article, I will explain why we use this material, how it compares to ordinary glass, and what advantages it brings to users in terms of performance and safety.
Different Kinds of Glass Used in Water Bottles
There are different kinds of glass water bottles. According to research done in the industry and common manufacturing standards in China and around the world, there are two main types of glass used for water bottles:
| Glass Type | Features | Common Use |
|---|---|---|
| Soda-lime glass (ordinary glass) | Cheap, low heat resistance, easy to break | Food jars, normal glassware |
| High borosilicate glass | High temperature resistance, strong durability, safe | High-quality glass bottles, lab glassware |
Soda-lime glass is used in most cheap bottles, but it can break easily when hot water is poured on it or when the temperature changes quickly. That’s why we don’t use it at Diller.
Why Diller Uses High Borosilicate Glass
High borosilicate glass is a high-quality material that is known for being stable at high temperatures and not breaking easily. Because it is safe and pure, it is used a lot in labs and kitchenware.
Key Advantages of High Borosilicate Glass
-
High temperature resistance (from -20°C to 150°C)
-
Thermal shock resistant (can handle boiling water)
-
BPA-free and toxin-free
-
Does not absorb flavors or odors
-
Safe for tea, fruit infusions, and hot drinks
-
Eco-friendly and recyclable material
Boron trioxide is in high borosilicate glass, which makes the molecular structure more stable than in regular glass. Because of that stability, people can safely pour hot tea or boiling water into it without worrying about it cracking.
High Borosilicate Glass vs Ordinary Glass
| Feature | Ordinary Glass | High Borosilicate Glass (Used by Diller) |
|---|---|---|
| Heat resistance | Low | High |
| Durability | Easy to break | Strong against impacts |
| Safety | May contain impurities | Food-grade safe |
| Chemical resistance | Weak | Excellent |
| Suitable for hot drinks | ❌ No | ✅ Yes |
| Price | Low | Higher but worth it |
Are Diller Glass Bottles Safe?
Yes, because we follow international food-grade safety standards, including:
-
FDA (U.S. Food and Drug Administration)
-
LFGB (German Food Safety)
-
BPA-free certification
-
ISO quality control
We also upgrade functional parts like silicone seals, PP lids, stainless steel filters, and protective sleeves, making our bottles practical not just safe.
Why We Prefer High Borosilicate Glass at Diller
As a manufacturer, I focus on material quality first. Price competition in the glass bottle industry is common, but we do not use low-grade glass just to lower production cost. Instead, we produce durable, safe, and healthy bottles designed for daily and long-term use.
At Diller, we choose high borosilicate glass because:
-
It is a safe long-term drinking solution
-
It preserves the natural taste of water
-
It is reliable for customers who use hot drinks
-
It aligns with our environmental values — reusable and recyclable
Final Thoughts
The best material for modern glass water bottles is high borosilicate glass because it is safe, long-lasting, and can handle heat. That’s why we use it as the main material to make our glass bottles. When I design and make bottles at Diller, I always think about how long they will be useful instead of how much they will cost in the short term.
We can make both standard and custom private label glass bottles, as well as OEM/ODM glass bottles, custom glass bottles with your logo, and wholesale high borosilicate glass bottles.
