In the modern viticulture landscape, the Screw Cap (Stelvin) has transitioned from a convenience feature to a gold standard for wine preservation. As a leading China screw cap wine bottles manufacturer, we understand the chemistry behind the seal. Unlike traditional cork, precision-engineered screw caps provide an airtight seal that eliminates TCA (2,4,6-trichloroanisole) contamination, also known as "cork taint."
For high-turnover varietals and premium aging wines alike, the BVS (Bague Vin Suisse) finish ensures consistent Oxygen Transmission Rates (OTR). This allows winemakers to predict the aging trajectory with clinical precision, a factor that is driving global procurement shifts from Europe to advanced Chinese facilities.
TCA-Free Guarantee compared to traditional corking
Reduction in storage loss through superior seal integrity

Avail yourself of our complimentary glass bottle samples, aiding you in solidifying your decision to invest in our premium selections before bulk purchase.
1. Scale & Supply Chain Integration: China's glass manufacturing hubs offer unparalleled vertical integration. From raw silica sand processing to the advanced metallurgical production of aluminum screw caps, every step is optimized. This allows us to offer factory-direct pricing that European competitors cannot match.
2. Advanced Material Science: Our factories utilize high-flint and extra-flint glass formulations. These provide the structural integrity required to handle the torque of automatic capping machines without risking stress fractures at the neck—a common issue in lower-quality glass.
3. Customization & Branding: Beyond the bottle, we offer "Full-Stack Branding." This includes silk-screen printing, frosted finishes, and embossed logos directly on the glass. The screw caps themselves can be litho-printed with complex brand motifs, providing a premium shelf presence.
4. Rapid Prototyping: Utilizing AI-driven design tools and 3D printing for initial molds, we reduce the "concept-to-sample" time from months to weeks, enabling wineries to react quickly to market trends.

All our glass production meets FDA (USA), LFGB (Germany), and EU food-grade standards. We ensure lead-free composition and rigorous heavy metal testing for safe international export.
We provide palletized or bulk-pack solutions optimized for 40HC containers. Our shock-absorption packaging tech reduces breakage rates to under 0.5% during cross-ocean transit.
Glass is 100% recyclable. We are integrating more cullet (recycled glass) into our melting process to reduce carbon footprints, a key requirement for ESG-conscious global brands.
As a leading Chinese glass bottle manufacturer, we take pride in our ability to produce glass bottles from start to finish. Our integrated processes encompass raw material crushing and mixing, precise batching, melting, shaping, and meticulous annealing, ensuring top-notch quality at every step.
Our facility operates 24/7 with automated inspection systems (IS machines) that detect microscopic flaws, ensuring that every screw cap thread is perfectly calibrated for a leak-proof seal.
Screw caps eliminate cork taint (TCA), provide a more consistent oxygen seal, and offer consumer convenience for easy re-opening and storage.
Yes, we offer Antique Green, Amber, Cobalt Blue, and Flint (Clear). We can also apply custom sprays and coatings for specific brand colors.
For standard models, the MOQ is usually one 20ft container. For custom molds, it typically starts at 30,000 units depending on the design complexity.
We use automated optical inspection machines and conduct manual pressure tests, thermal shock tests, and thread measurement checks every hour.
Our bottles are designed to BVS 30H60 standards, making them fully compatible with high-speed Stelvin and other global capping equipment.
Absolutely. We offer lightweight glass options that reduce raw material use and shipping emissions without compromising strength.
As global consumption habits shift towards convenience and guaranteed quality, the demand for high-performance screw cap wine bottles continues to surge. Our role as a manufacturing partner is to provide the reliability, technical expertise, and cost-efficiency required to help your brand scale globally. Whether you are a boutique winery or a global spirits conglomerate, our China-based facility is equipped to handle your most demanding glass packaging requirements.
