Why are most wine bottles packed in glass bottles

Introduction  

From crisp beers to aromatic Baijiu, glass bottles dominate global beverage packaging, holding 71% of the beer container market and 55% of Chinas production (50+ billion bottles annually). As a leader with 17 years of glass manufacturing excellence, QLT Glass crafts bottles that combine tradition with innovation, ensuring unmatched performance for breweries, wineries, and spirits brands worldwide.  

 

 

 

1. The Unmatched Advantages of Glass Bottles  

 

A. Chemical Resilience & Hygiene  

Glass withstands high-alkaline wash cycles (up to pH 12) without corrosion, critical for reusable beer bottles. QLT Glass enhances this with:  

- Proprietary Surface Treatments: Nano-coatings reduce residue buildup by 40%  

- FDA-Compliant Materials: Guaranteed non-toxic, odor-free performance  

 

B. Pressure & Carbonation Integrity  

With beer bottles containing 34 volumes of CO, glasss structural strength prevents explosions. QLT Glass ensures safety through:  

- Pressure Testing: 15+ bar resistance (exceeding industry standards)  

- Uniform Wall Thickness: ±0.3mm precision via AI-guided IS machines  

 

C. Thermal Stability  

Surviving 150°C sterilization and -20°C storage, glass outperforms plastic. QLT Glass optimizes this with:  

- Borosilicate Formulas: 30% higher thermal shock resistance  

- Annealing Technology: Stress-relieved bottles with <5 μm/cm distortion  

 

D. Superior Sealing & Freshness  

Glasss zero oxygen permeability preserves flavors for 18+ months. QLT Glass offers:  

- Laser-Engraved Necks: Perfect seal alignment for cork/cap systems  

- UV-Blocking Tints: Amber/green glass filters 99% harmful light  

 

 

 

2. QLT Glass: Pioneering Sustainable Packaging  

 

Recycling Impact:  

- Every 6 tons of recycled glass saves 6 tons of raw materials and cuts 1 ton of CO₂  

- QLT Glass amplifies this with 30% recycled cullet in production
