As the core carrier of beverage packaging, the quality of glass wine bottles directly affects product value and consumer experience. Wholesale customers should focus on the following professional key points:
1. Material and Safety Standards
The mainstream adopts borosilicate glass (high temperature resistant, impact resistant) and soda-lime glass (cost-adaptive). It is necessary to recognize food-grade certifications (such as GB 4806.5) and focus on checking the lead and cadmium dissolution (≤0.1mg/L) to avoid secondary pollution of beverages, especially suitable for long-term storage scenarios such as red wine and white wine.
2. Process and Cost Control
Automatic bottle blowing technology (output ≥800 bottles/hour) can reduce mass production costs. The uniformity of bottle wall thickness (error ≤0.2mm) affects the transportation breakage rate (high-quality products ≤0.3%), and lightweight design (15%-20% lighter than traditional bottles) can save logistics and storage costs.
3. Customization Adaptability
The bottle mouth specification (such as crown cap and screw cap adaptation) needs to match the filling line. The bottle shape design should consider the convenience of labeling and stacking stability. Processes such as in-mold labeling and decal can be provided to improve product recognition. The minimum order quantity (MOQ) is usually 50,000 pieces, and color customization is supported.
Choosing factories with SGS and ISO9001 certifications can ensure the consistency and delivery stability of mass-produced products and reduce cooperation risks.
