The main characteristics of the glass bottle packaging container are: non-toxic, tasteless; transparent, beautiful, good barrier properties, airtight, abundant and common raw materials, low price, and can be used in multiple cycles. And it has the advantages of heat resistance, pressure resistance, and cleaning resistance. It can be sterilized at high temperatures and can be stored at low temperatures. Because of its many advantages, glass bottle packaging has become a packaging material for many beverages such as beer, fruit tea, and jujube juice. Below, Cosmetic Package Manufacturers introduces the glass bottle production process mainly including:
①Pre-processing of raw materials. Crush the bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.), dry the wet raw materials, and remove iron from the iron-containing raw materials to ensure the quality of the glass.
② Preparation of batch materials.
③Melting. The glass batch material is heated at a high temperature (1550~1600 degrees) in a pool furnace or a pool furnace to form a uniform, bubble-free liquid glass that meets the molding requirements.
④Forming. Put the liquid glass into the mold to make glass products of the required shape, such as flat plates, various utensils, etc.
⑤ Heat treatment. Through annealing, quenching, and other processes, the internal stress, phase separation, or crystallization of the glass is eliminated or generated, and the structural state of the glass is changed.
