Molded bottles and controlled bottles are two main types of glass bottles, and they have significant differences in manufacturing processes, appearance, materials, and applications.
Molded bottles and tubular bottles are two main types of glass bottles, and they have significant differences in manufacturing processes, appearance, materials, and applications.
First, from the perspective of manufacturing processes, molded bottles are formed by processing molten glass using molds, while tubular bottles are made by using flame heating equipment to shape glass tubes into specific shapes and volumes. Molded bottles require a complete set of molds, while tubular bottles mainly rely on mold wheels for shaping.
Secondly, in terms of appearance and materials, molded bottles typically have thicker walls, are heavier, and have a rougher appearance, mainly made of soda-lime glass; whereas tubular bottles have uniform wall thickness, are lighter, and have a more refined appearance, primarily made of borosilicate glass (including low borosilicate, medium borosilicate, and high borosilicate).
Finally, in terms of applications, molded bottles are widely used in industries such as beverages, health products, and cosmetics, with various capacity specifications; while tubular bottles are more suitable for pharmaceutical packaging, especially for small-volume injectables and lyophilized powder medications, which have unique advantages.
In summary, molded bottles and tubular bottles each have their characteristics in manufacturing processes, appearance, materials, and applications. The choice of which type of glass bottle to use should be based on specific needs and product characteristics.
