INTRODUCTION OF GLASS BOTTLE
FEATURE AND ADVANTAGE OF GLASS BOTTLE
1. Glass materials have good barrier properties, which can prevent the invasion of oxygen and other gases on the inner contents, and prevent the volatile components of the inner contents from volatilizing into the atmosphere.
2. Glass bottles can be used repeatedly to reduce packaging costs.
3. Glass can easily change its color and transparency.
4. Glass bottles are safe and hygienic. They have good corrosion resistance and acid resistance. They are suitable for packaging acidic substances (such as vegetable, juice, beverage, etc.).
5. Glass bottles are suitable for automatic filling production line
ENERGY SAVING AND ENVIRONMENTAL PROTECTION
Over the past decade, the practice of technological renovation in glass melting furnaces around the world has shown that oxy-fuel combustion technology has remarkable advantages such as low investment, low energy consumption and low pollutant emissions. In the United States and Europe, lightweight bottles and cans have become the leading products of glass bottles and cans. Small mouth pressure blowing technology (NNPB), cold and hot end spraying technology of bottles and cans are all advanced technologies of lightweight production.
The German company has been able to produce a 1 liter concentrated juice bottle, weighing only 295 grams. The glass bottle wall is coated with organic resin, which can increase the pressure strength of the bottle by 20%. In modern factories, it is not easy to produce glass bottles. There are many scientific problems to be solved.
In our daily life, glass bottles can be seen everywhere. Whether it is beverages, drugs, cosmetics, etc., glass bottles are their good partners. These glass bottles, because of their transparent aesthetic feeling, good chemical stability, no pollution to the contents, can be heated at high temperature, recyclable old bottles and other advantages, have been considered as the best packaging materials.
PRODUCTION PROCESS OF GLASS BOTTLE
Firstly, the blowing mold should be designed and manufactured. The raw material of glass polyurethane is quartz sand as the main raw material, and other auxiliary materials melt into liquid at high temperature. Then, the glass bottle can be formed by feeding machine to drop into the mold, air-jet, air-pouring, pressing, annealing and other processes. Glass bottles usually have rigid marks, which are also made from the shape of the mould.
APPLICATION OF GLASS BOTTLE
Glass bottles as packaging materials are mainly used in food, oil, alcohol, beverages, condiments, cosmetics and liquid chemical products, etc. They are widely used.
HOW TO CHOOSE GLASS BOTTLE
There are many kinds of glass bottles, ranging from small bottles with 1ML capacity to large bottles with dozens of liters, from round, square, shaped and handle bottles, from colorless and transparent amber, green, blue, black shading bottles and opaque opaque glass bottles, etc. As far as manufacturing technology is concerned, glass bottles are generally divided into two categories: moulding bottles (using model bottles) and control bottles (using glass bottles). Molded bottles can be divided into two categories: large-mouth bottles (with a diameter of more than 30MM) and small-mouth bottles. The former is used to hold powdery, massive and pasty articles, while the latter is used to hold liquids. According to the form of bottle mouth, it can be divided into cork bottle mouth, thread bottle mouth, crown cap bottle mouth, rolled bottle mouth grinding bottle mouth, etc. According to the usage situation, it can be divided into "one-time bottle" which is discarded once and "recycling bottle" which is used many times. According to the classification of containers, it can be divided into wine bottles, beverage bottles, oil bottles, canned bottles, acid bottles, medicine bottles, reagent bottles, infusion bottles, cosmetic bottles and so on.
