A toast to the bright moon and the shadow into three people. However, have you ever wondered why all beer is sold in glass bottles or cans? Plastic bottles, what is the enemy with beer?

Plastic this material has changed our lives: not only cheap, but also change, as you how to pinch, is a good temper. What's more, it can be easily recycled. In this case, why do we still use glass bottles and cans for beer? Is it because of beauty? Taste? Or is there some other reason?

Many people do not know that in some places beer is sometimes packed in plastic bottles, such as the UK, in some celebrations or similar occasions, plastic bottled beer is very common. In fact, alcohol in plastic bottles is mandatory at particularly grand events in the UK.

For example, during the 2012 London Olympics, Heineken, the official beer sponsor of the Olympic Games, placed many refrigerators throughout London, containing more than one million bottles of plastic-packed beer specially designed for the Olympics. Although they claim to be environmentally friendly, they are still concerned about safety. Because every place you go there are thousands of people who are drunk. Although they have different cultural backgrounds, they are all sports enthusiasts. It is wise not to give them glass bottles or anything that can be used as a murder weapon. Otherwise, once the team fan's people accidentally step on the feet of the supporting B team fans......

Plastic bottled beer, easy to "no gas"

At this time, some people ask, why not promote the use of plastic bottles around the world? The answer is from our own point of view, with plastic bottles of beer will affect the taste of beer. Plastic is more permeable than glass (glass itself is impermeable to oxygen and carbon dioxide). In other words, beer (or other soft drinks) is more likely to "empty" and taste bland in plastic bottles than in glass bottles, because the carbon dioxide that can make beer bubble is more easily lost. Glass has another advantage. It has no taste and will not react chemically with what is inside. To quote the Glass Life: "Eating and drinking in glassware gives you the most authentic taste of food and drink-no more, no less."

Plastic, on the other hand, is full of chemicals, and it's very likely to seep into your drink and ruin your beer or something.

For example, when polyester plastic containers are manufactured, antimony is often used as a catalyst, and residual antimony may penetrate into the beverage. At room temperature or below room temperature, the antimony content in the beverage is harmless to the human body. Once the temperature rises, the antimony content will also increase. Therefore, if the beverage is kept in an unsealed warehouse for several months in summer or other warm places, the antimony content in it greatly exceeds the standard.

"Avoiding light" is their storage nirvana.

As for aluminum cans, like glass, aluminum is not very permeable, so it has also become an excellent material for storing beer. Interestingly, the inside of the aluminum can is coated with a special polymer coating to inhibit the penetration of aluminum into the beverage, making the can safer to store; because excessive aluminum content in the body can lead to Alzheimer's disease and Parkinson's syndrome.

Incidentally, the first Parkinson's doctor to discover and report on Parkinson's syndrome was also involved in the assassination of George III.

In any case, aluminum cans can fully protect beverages from light and protect them better than other types of packaging.

In fact, we store beer in glass, specifically colored glass, because it protects the beer from the sun. In fact, plastic can also be made of the same color, but it may disturb the existing order of the plastic recycling system. If plastic beer bottles are made amber like glass bottles, they need to add an additional layer of coating to protect the beer in the bottle, which is more difficult to recycle than the transparent plastic bottles favored by the soft drink industry.

Another problem with plastic bottle packaging is that they cannot be pasteurized. After the beer is brewed, it is usually sent to a machine where it is sprayed with boiling water to heat the liquid and kill bacteria that may have survived the brewing process. This will ensure the quality and safety of beer and extend the shelf life. Glass bottles and aluminum cans can easily do this procedure, while plastic bottles are likely to deform. This means that this sterilization procedure needs to be omitted, or a more resistant (harder plastic container, but this will raise costs and companies can avoid it.

However, there are indeed beer manufacturers trying to make the popularization of plastic bottled beer a reality (and to convince the public to accept such a change), but for now, it seems that glass and aluminum cans can still dominate the business, plastic bottles? Or play with the drinks.
