One of the main products of glass bottle is the familiar and favorite packing container. In recent decades, with the development of industrial technology, a variety of new packaging materials, such as plastic, composite materials, special packaging paper, tinplate, aluminum foil, have been produced. Glass as a packaging material is in fierce competition with other packaging materials. Due to the advantages of transparency, good chemical stability, low price, beautiful appearance, easy to manufacture and recycle for many times, glass products can not be replaced by other packaging materials despite the competition of other packaging materials.
全民彩票In recent years, through more than ten years of life practice, people have found that eating plastic barrels (bottles) of edible oil, wine, vinegar and soy sauce will bring harm to human health:
1. For a long time, use plastic barrels (bottles) to load edible oil. Edible oil will surely dissolve into plasticizers harmful to human body. 95% of edible oil on the domestic market is filled in plastic barrels (bottles). Once stored for a long time (usually more than a week), edible oil will dissolve into plasticizers harmful to human body. Domestic experts have collected different brands of plastic barrels (bottles) of soybean salad oil, blended oil and peanut oil on the market for tests. The test results show that all plastic barrels (bottles) tested contain plasticizer "dibutyl phthalate".
全民彩票Plasticizers have a certain toxic effect on the human reproductive system, and more toxic to men. But because the toxic effect of plasticizer is chronic and hard to detect, it has been widely used for more than ten years, and now it has attracted the attention of experts at home and abroad.
2. The condiments such as wine, vinegar and soy sauce contained in plastic barrels (bottles) are easy to be polluted by ethylene, which is harmful to human body. Plastic barrels (bottles) are mainly made of polyethylene or polypropylene and other materials with a variety of solvents added. Polyethylene and polypropylene are non-toxic materials, which have no effect on human body when used for canned drinks. However, the plastic bottle still contains a small amount of ethylene monomer in the production process. If alcohol, vinegar and other fat soluble organic matters are stored for a long time, physical and chemical reactions will occur, and the ethylene monomer will dissolve slowly. In addition, plastic barrels (bottles) are used to hold wine, vinegar, soy sauce, etc. in the air, plastic bottles will be aged by the effects of oxygen, ultraviolet rays, etc., releasing more vinyl monomers, which will make the wine, vinegar, soy sauce, etc. stored in the barrels (bottles) deteriorate.
Long term consumption of ethylene contaminated food will lead to dizziness, headache, nausea, loss of appetite, memory loss and other symptoms. Severe cases can also lead to anemia. It can be concluded from the above: with the continuous improvement of people's pursuit of quality of life, people will pay more and more attention to the safety of food. With the popularization and deepening of consumers' awareness of the hazards of plastic barrels (bottles) of cooking oil, vinegar, soy sauce, etc., glass bottles and jars are beneficial to human health. Packaging containers will gradually become the consensus of consumers and will become glass New opportunities for the development of glass bottles and jars.
