Glass bottles are packaging containers made from raw materials such as quartz sand, soda ash, feldspar, and limestone through high-temperature melting, molding, annealing, and other processes. In the field of packaging, glass bottles occupy an important position with numerous advantages. Below is a detailed introduction from the aspects of chemical stability, barrier properties, transparency, shape and decoration, recyclability, etc.:
Good chemical stability: The main component of glass is silicon dioxide, which has good chemical inertness. This makes glass bottles less prone to chemical reactions with the contents when storing various items, ensuring that the quality and characteristics of the product remain stable during the shelf life. For example, when used to hold acidic beverages such as orange juice, cola, etc., they will not spoil due to the erosion of acidic substances; When storing alcoholic beverages, they will not react with alcohol, ensuring the flavor and quality of the wine.
Excellent barrier performance: Glass bottles have high barrier properties against gases (such as oxygen, carbon dioxide), water vapor, etc. This feature effectively prevents the contents from deteriorating due to external environmental factors such as oxidation and moisture. Taking food packaging as an example, such as bottled jam, good barrier properties can prevent oxygen from entering the bottle, prevent the components in the jam from oxidizing and spoiling, and extend its shelf life; For carbonated beverages, it can prevent carbon dioxide from escaping, maintain the bubbles and taste of the beverage.
High transparency: Glass bottles have extremely high transparency, allowing consumers to directly observe the appearance, color, and condition of the products inside the bottle, making it easy for consumers to choose products. Like cosmetics packaging, consumers can directly see the texture and color of lotion and face cream; In drug packaging
