Glass Packaging Process Innovation And Development Trends 2025

Glass packaging for its environmental protection, chemical inertness and high-end texture, in the food, cosmetics, pharmaceuticals and other fields continue to occupy an important position. The following is the current mainstream glass packaging process and innovation direction, combined with technological breakthroughs and market demand for systematic combing:

I. Core Molding Process
1. Blow Molding (Blow Molding)
Application: wide-mouth bottles, wine bottles, perfume bottles and other hollow containers.
Technology upgrade:
CNC precision blow molding: air pressure and mold temperature are controlled by AI algorithm with error ≤ 0.1mm (e.g. Moutai wine bottle).
Lightweight technology: the thickness of bottle wall is reduced from 1.2mm to 0.8mm with the same strength (EU “Eco-Design” standard). 2.

2. Press & Blow
Characteristics: Suitable for high volume production of standard bottle shapes (e.g. can bottles, medicine bottles).
Innovations:
Multi-cavity molds: press 4-8 bottles in a single run, 300% more efficient.
Ultra-white glass application: light transmittance ≥ 91% (demand for cosmetic bottles is surging).

3. Tube Forming (Tube Forming)
Application: small diameter bottles (e.g. oral liquid bottles, perfume droppers).
Breakthrough: laser cutting instead of traditional mechanical cutting, smoother incision (50% reduction in fragmentation rate).

II. Surface Treatment and Decorative Processes
1. Spraying and Coating
Environmentally friendly water-based paint: 90% reduction in VOC emissions, scratch-resistant (e.g., Starbucks glass cups).
PVD Vacuum Coating: Realize metallic luster (gold/silver/rose gold), replace electroplating process. 2.

2. Screen Printing
High-precision UV ink: supports gradient color and fluorescent effect (e.g. Absolut Vodka Limited Edition).
Tactile Printing: Embossed logo or frosted texture (to enhance the luxury of cosmetic bottles).

3. Laser Engraving (Laser Engraving)
Dynamic marking: Gradient patterns of shades (e.g., commemorative wine bottle numbering) are realized through parameter adjustment.
Anti-counterfeiting applications: micron-level invisible coding (pharmaceutical bottle anti-counterfeiting requirements).

4. Biodegradable Coatings
Innovation Directions:
Plant-based coatings (e.g. corn protein) to replace PE lamination, making glass bottles 100% recyclable.
Self-cleaning coating (titanium dioxide) for outdoor beverage bottles.
