Borosilicate Double-wall Glass Cups Wholesale

As a star product that has attracted much attention in recent years, high borosilicate double-wall glass cups have quickly become the first choice for families, businesses, and the catering industry due to their excellent performance, diverse styles, and flexible customization services. This article will deeply analyze the core advantages, design diversity, and factory strength of high borosilicate glass cups, and show you why it can become an "all-round player" in the market.

Advantages of borosilicate glass cups:

Safe and durable ultimate material
The silicon dioxide content of borosilicate glass is as high as 80%, and the boron element accounts for 12%-15%, which is far higher than ordinary soda-lime glass (containing only 70% silicon dioxide). This special ratio gives it three major characteristics:

Strong resistance to temperature difference: It can withstand instantaneous temperature difference from -20℃ to 150℃. There is no risk of bursting when directly injected with boiling water or taken out of the refrigerator, and it completely bids farewell to the hidden danger of "thermal expansion and contraction".

Impact resistance upgrade: The hardness is twice that of ordinary glass, and it is not easy to break in daily bumps, and the service life is significantly extended.

Pure and pollution-free: It does not contain heavy metals and chemical coatings, and there is no odor precipitation for hot and cold drinks. It has passed FDA and SGS food safety certification, and mothers and babies can also use it with confidence.

Double-wall insulation design
Traditional single-layer glass cups are easy to burn when holding hot drinks, and cold drinks are easy to condense and slip. The high borosilicate double-layer glass cup perfectly solves the pain points through vacuum interlayer technology:

Insulation and anti-scalding: The double-layer structure blocks heat transfer. Even if 98℃ hot water is injected, the cup body feels gentle and does not require a cup sleeve.

Anti-condensation water: When drinking cold drinks, the outer glass isolates the temperature difference, avoids condensation of water droplets on the cup wall, and keeps the table dry.

Comfortable grip: The curvature of the cup body fits the hand shape, and is matched with frosted, threaded and other surface treatment processes, which is non-slip and ergonomic.

Balance between transparent aesthetics and diversified design
The light transmittance of high borosilicate glass is as high as 92%, and the crystal clear texture can clearly show the color of the drink (such as coffee latte art, fruit tea layering), enhancing visual enjoyment. At the same time, through hot melt shaping and cold processing carving technology, the cup body can be created:

Simple straight cup: suitable for office and home scenes, versatile and practical.

Retro coffee cup: The narrow mouth design locks in the aroma, and it is matched with a wooden cup holder, which is full of ritual sense.

Creative shaped cup: star pattern, faceted cutting, streamlined cup body, satisfying the young group's pursuit of "Internet celebrity hits".

Easy to clean and long-term use
The surface of high borosilicate glass is smooth and non-porous, and it is not easy to leave tea stains and coffee stains, and it can be cleaned by rinsing with clean water. At the same time, its acid and alkali resistance is far superior to ordinary glass, and there is no risk of corrosion even if it is in contact with lemon juice and carbonated drinks for a long time.
Environmental sustainability
As a 100% recyclable material, high borosilicate glass cups can be used repeatedly, reducing the consumption of disposable plastic cups, which is in line with the global environmental protection trend.

We can customize a variety of high borosilicate double-layer glass cups, which can cover multi-dimensional scenarios such as home, business, and catering, including business gift series, catering industry series (coffee shops, bars), offline supermarket series, etc.
