As one of the main glass products, bottles and cans are familiar and favorite packaging containers. In recent decades, with the development of industrial technology, a variety of new packaging materials such as plastics, composite materials, special packaging paper, tinplate, and aluminum foil have been manufactured. The packaging material of glass is in fierce competition with other packaging materials. Because glass bottles and cans have the advantages of transparency, good chemical stability, low price, beautiful appearance, easy production and manufacturing, and can be recycled and used many times, even if they encounter competition from other packaging materials, glass bottles and cans still have other packaging materials that cannot be replaced. specialty.
In recent years, through more than ten years of life practice, people have discovered that edible oil, wine, vinegar and soy sauce in plastic barrels (bottles) are harmful to human health:
1. Use plastic buckets (bottles) to store edible oil for a long time. The edible oil will definitely dissolve in plasticizers harmful to the human body.
95% of the edible oil on the domestic market is packed in plastic drums (bottles). Once stored for a long time (usually more than a week), the edible oil will dissolve in plasticizers harmful to the human body. Relevant domestic experts have collected soybean salad oil, blended oil, and peanut oil in plastic barrels (bottles) of different brands and different factory dates on the market for experiments. The test results show that all tested plastic barrels (bottles) contain edible oil. Plasticizer “Dibutyl Phthalate”.
Plasticizers have a certain toxic effect on the human reproductive system, and are more toxic to men. However, the toxic effects of plasticizers are chronic and difficult to detect, so after more than ten years of their widespread existence, it has only now attracted the attention of domestic and foreign experts.
2. Wine, vinegar, soy sauce and other condiments in plastic barrels (bottles) are easily contaminated by ethylene which is harmful to humans.
Plastic barrels (bottles) are mainly made of materials such as polyethylene or polypropylene and added with a variety of solvents. These two materials, polyethylene and polypropylene, are non-toxic, and canned beverages have no adverse effects on the human body. However, because plastic bottles still contain a small amount of ethylene monomer during the production process, if fat-soluble organic substances such as wine and vinegar are stored for a long time, physical and chemical reactions will occur, and the ethylene monomer will slowly dissolve. In addition, plastic barrels (bottles) are used to store wine, vinegar, soy sauce, etc., in the air, plastic bottles will be aged by the action of oxygen, ultraviolet rays, etc., releasing more vinyl monomers, making the wine stored in the barrels (bottles) , Vinegar, soy sauce and other spoilage.
Long-term consumption of food contaminated with ethylene can cause dizziness, headache, nausea, loss of appetite, and memory loss. In severe cases, it can also lead to anemia.
From the above, it can be concluded that 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 popularity and penetration of glass bottles and cans, glass bottles and cans are a kind of packaging container that is beneficial to human health. It will gradually become the consensus of the majority of consumers, and it will also become a new opportunity for the development of glass bottles and cans.
