Glass packaging materials and containers offer numerous advantages:

  1. Excellent Barrier Performance: Glass provides effective protection against oxygen and other gases, preventing their invasion into the contents. It also prevents the volatile components of the contents from escaping into the atmosphere.
  2. Reusability: Glass bottles can be reused, reducing packaging costs and promoting sustainability.
  3. Versatility: Glass can be easily colored and made transparent, allowing for a variety of options in terms of appearance and design.
  4. Safety and Sanitation: Glass bottles are safe and hygienic, exhibiting good corrosion and acid resistance. They are suitable for packaging acidic substances such as vegetable juice drinks.
  5. Compatibility with Filling Technology: Glass bottles are well-suited for automatic filling production lines. The technology and equipment for automatic filling of glass bottles are mature, particularly in China, making glass bottle packaging advantageous for fruit and vegetable juice beverages.

Glass bottles possess several characteristics, including good chemical stability, easy sealing, excellent airtightness, and transparency for external observation. They offer efficient storage capabilities, have a clean surface that is easy to disinfect and sterilize, and come in attractive shapes with various decorative options. Glass bottles exhibit sufficient mechanical strength to withstand internal pressure and external forces during transportation. Raw materials for glass bottles are widely available and cost-effective.

Although glass bottles have drawbacks such as weight and brittleness, advancements in technology, such as thin-wall lightweight designs and physical and chemical tempering, have significantly improved these limitations. Consequently, glass bottle production continues to grow in competition with plastic, tin, and iron containers.

Glass bottles come in various types, ranging from small 1ml bottles to large containers exceeding ten liters. They can have different shapes, including round, square, and custom designs, and are available in colorless, transparent, amber, green, blue, black, and opaque variations. Manufacturing techniques for glass bottles include molding (using model bottles) and tube forming (using glass tube bottles). Molding bottles are further categorized into wide-mouth and narrow-mouth bottles, serving different purposes. The bottle mouth can be designed as cork, screw, cap, roll-on, or grind types. Glass bottles are used across multiple industries, including wine, beverages, oils, medications, reagents, infusions, cosmetics, and more.
