Can wine be packaged in plastic bottles?

China's wine culture has a long history. Many people like to have a drink or two. There is no harm in drinking moderately. Some areas often sell loose wine, which is made by some personal workshops. When buying this kind of wine, in addition to paying attention to whether it is grain wine, you should also pay attention to the packaging. Try not to use plastic bottles. Let's take a look at this aspect.

Can plastic bottles hold liquor?

1. Plastic bottles are mostly made of polyethylene plastic. The monomer of polyethylene is insoluble in water but soluble in alcohol. Experiments have shown that if wine is stored in a polyethylene plastic bottle for one year, the polyethylene can dissolve in the alcohol in large quantities. After people drink this kind of wine, they will experience dizziness, headache, nausea, loss of appetite, memory loss, etc. In severe cases, it can also lead to anemia.

2. Currently, the plastic bottles that can be used to store liquor are PET (polyester) plastics. PET can be used for highly soluble foods and beverages such as wine and cooking oil. Because PET is a new type of high-molecular polyester material with a more stable molecular structure, it has been widely used in foreign countries for packaging of low-alcohol beverages such as beer. However, although this material is harmless, it is not as airtight as glass bottles, so it is not suitable for long-term storage.

3. Therefore, after you buy the liquor home, be sure to store it in a glass bottle or consume it as soon as possible.

Plastic bottles can be used to store liquor for a short period of time.

Liquor in plastic bottles should not be stored for too long, otherwise the plastic will decompose and produce carcinogens. In addition, the plasticizers in plastic bottles can be dissolved in alcohol and are harmful to the human body, so it is best not to use plastic bottles to store liquor.

Baijiu is a slightly acidic alcohol solution beverage. Depending on the percentage of alcohol by volume, it is divided into strong liquor (about 50 degrees or above), reduced-alcohol liquor, and low-alcohol liquor (about 40 degrees or below). It also contains a variety of naturally fermented organic acids. Therefore, as long as the material of the plastic bottle itself can be directly in contact with liquor of different alcohol content without being slowly dissolved by alcohol or corroded by acid, and will not cause the taste of the liquor to change, it can be filled. Otherwise, it cannot be filled. General food plastic bottles, such as mineral water bottles, are mostly made of polyethylene organic material, which can be miscible with organic solvents such as alcohol, but the dissolution rate varies depending on different conditions such as concentration. It can be seen from this that plastic bottles cannot be used to store liquor for a long time. The higher the alcohol content, the less likely it is to be stored for a long time. Even low-alcohol liquor can only be stored temporarily or used for turnover.
