Glass bottles quality requirements

1.Glass bottle raw materials

Glass bottles in production, the different raw materials will determine the quality of glass products, raw materials are divided into green and white material, general white material, high white material and crystal white material, which are increasingly good quality, he directly affects the transparency and brittleness of the glass bottle, the better the raw materials produced the better the quality of glass products.

• Green and white materials are low cost and cheap, but they are not resistant to high temperature and pressure;
• The cost of ordinary white material is higher, more expensive, resistant to high temperature and pressure, but not high transparency.
• High white material, feel the crystal material feel, looks much worse, but with the general white material is not a class.
• Crystal white material is absolutely high-grade, like jade like smooth, crystal transparent, and crystal white material compared to the general white material, always feel that there are mixed colours.

2.The quality requirements of glass bottles

Glass bottles and jars should have certain properties and meet certain quality standards.

• Glass Quality: pure and proportionate, no sand, patterns, vapor bubbles and other shortcomings.
• Physical and Chemical Properties: with a certain degree of organic chemical reliability, not with the efficacy of the contents. With a certain durability and impact toughness, can withstand cleaning, decontamination and other heating, cooling the whole process and undertake canning, storage and transportation.
• Forming Quality: maintain a certain capacity, net weight and look, with proportionate wall thickness, rounded and flat mouth to ensure convenient filling and good sealing. No distortion and deformation, unevenness of the surface, unevenness and cracks, etc.

3.How are glass wine bottles made?

The first step is to design and determine and manufacture the mould. The glass raw material is made of quartz sand as the main raw material, plus other auxiliary materials dissolved into liquid form under high temperature, then injected into the mould, cooled, cut and tempered, it forms the glass bottle. Glass bottles are generally marked with a rigid logo, and the logo is also made from the shape of the mould. Glass bottles are formed according to the production method can be divided into three kinds of manual blowing, mechanical blowing and extrusion molding. Glass bottles can be divided into the following categories according to their composition: firstly, soda glass, secondly, lead glass and thirdly, borosilicate glass.

　　The main raw materials for glass bottles are natural ores, quartzite, caustic soda and limestone. Glass bottles are highly transparent and resistant to corrosion, and contact with most chemicals will not change the nature of the material. Its manufacturing process is simple, its shape is free and versatile, it is hard, heat resistant, clean and easy to clean, and it has the characteristics of being reusable.
