Color selection of chemical glass bottles

In the chemical product packaging industry, chemical glass bottles have become one of the core containers due to their chemical stability, barrier properties, and recyclability, and the choice of bottle color directly affects product performance and safety. Color is not only about aesthetics, but also a key means of protecting content and extending shelf life. Chemical glass bottles of different colors can effectively block the damage of chemicals such as ultraviolet and visible light by absorbing or reflecting specific wavelengths of light, thereby maintaining product stability.

Color selection should comprehensively consider the characteristics of the content and the usage scenario. For strongly oxidizing or photosensitive substances such as hydrogen peroxide and certain dye intermediates, dark bottle bodies can significantly reduce photocatalytic reactions, avoiding decomposition or discoloration; Colorless transparent bottles are suitable for products that require frequent observation of liquid level or color, such as laboratory reagents and low sensitivity solvents, but must be stored strictly in the dark. In addition, industrial standards and regulations are also important bases - green or blue bottles are often used for chemical raw materials (such as edible essence) to meet sanitary specifications, while white or transparent bottles are often used for industrial acid-base reagents to facilitate the identification of leakage risks at an appropriate speed. Enterprises also need to evaluate cost and process compatibility: Dark glass requires a balance between performance and economy due to the high cost of adding metal oxides (such as iron and cobalt), which may affect the purity of recycling and reuse.

The color selection of chemical glass bottles is the result of the synergistic effect of technology, economy, and regulations. From the functional requirements of blocking light, to the practicality of matching usage scenarios, and to compliance with industry standards, every step needs to be accurately controlled. Enterprises should establish technical color selection standards based on the chemical properties, storage conditions, and target market requirements of the contents to avoid product failure or safety hazards caused by improper color.
