Glass Jar Energy Saving And Environmental Protection

Oct 24, 2017

Glass jar is a commonly used in food packaging, gift packaging, medicinal packaging of chemical containers.

Glass jar production process:

The production process of glass jar mainly includes raw material pre-processing. The lime raw materials (quartz sand, soda ash, limestone, feldspar, etc.) crushed, so that the wet raw materials dry, iron-containing raw materials for iron treatment to ensure the quality of glass. Preparation of mating materials. Glass batch material in the pool kiln or pool furnace for high temperature 1550 ~ 1600 degrees, heating, so that the formation of uniform, no bubbles, and meet the molding requirements of liquid glass molding. The liquid glass into the mold made of the required shape of glass products, such as flat, various utensils and other heat treatment. Through the annealing, quenching and other processes to eliminate or produce glass internal stress, phase or crystallization, and change the structure of the glass state.

recycle and re-use

The recovery of glass jars is increasing every year, but the amount of this recycling is huge and immeasurable

According to the Glass Packaging Association, the energy saved by a glass jar can be saved by about 100 hours of light bulb for 4 hours, allowing a computer to run for 30 minutes and watch a 20-minute TV show, so the recycled glass is A matter of great significance.

Glass jar recycling saves energy and reduces landfill waste capacity, can provide more raw materials for other products, including glass jars. According to the National Council for Chemical Products, the national consumption of plastic bottles reported that in 2009 about 2.5 billion pounds of plastic bottles were recovered, the recovery rate reached only 28%.

The main features of glass packaging containers are: non-toxic, tasteless; transparent, beautiful, good barrier, airtight, rich raw materials, low prices, and can be used many times. And has the advantages of heat, pressure, resistance to cleaning, both high temperature sterilization, but also low temperature storage. It is because of its many advantages, so become beer, fruit tea, jujube juice and many other preferred packaging materials.

71% of the world's beer filling in the glass beer bottles, and China is the world's largest proportion of glass beer bottles, accounting for 55% of the global glass beer bottles, each year more than 50 billion, glass beer bottles as beer packaging Mainstream packaging, after a hundred years of beer packaging changes in the vicissitudes of life, still its stable material structure, pollution-free, low prices by the beer industry's favor, "when the business want to have a beautiful appearance of packaging, but also give people cold The glass jar is still the preferred packaging for the beer business. "For the beer packaging made a great contribution, most people love to use it.

Energy saving and environmental protection

In the past decade, the practice of technological transformation in glass furnaces in the world has shown that the whole oxygen combustion technology has significant advantages such as low investment, low energy consumption and low pollutant discharge. In the United States, Europe, lightweight bottles are the leading products of glass jars, small mouth blowing technology (NNPB), hot and cold side of the bottle spray coating technology, are lightweight production of advanced technology.

German company has been able to produce 1 liter of concentrated juice bottles, weighing only 295 grams, glass tank wall coated with organic resin, can improve the bottle pressure intensity of 20%. In modern factories, the production of glass jars is not easy, there are a lot of scientific problems need to be resolved.

In our daily life, everywhere can see the glass jar figure. Whether it is drinks, drugs, or cosmetics, etc., glass jars are their good partners. These glass jars, because of its transparent beauty, good chemical stability, the contents of non-polluting, high temperature heating, the old bottle can be recycled and other advantages, has been considered the best packaging materials.
