In recent years, with the development of China's economy and the improvement of people's living standards, China's beverage market has shown a rapid development trend, with various new concept products emerging one after another and diversified packaging methods.

Although the packaging appearance of all kinds of drinking water has its own characteristics, when it comes to packaging materials, it can generally be divided into three types: metal cans, glass bottles and plastic bottles. What kind of packaging is the safest and most reliable for our consumers?

First of all, talk about metal can packaging.

Metal cans are rare in drinking water packaging, and are mostly used for sparkling mineral water or carbonated drinks. Drinking water tanks are mostly made of aluminum, which is more stable and lighter than glass bottles. At the same time, because of its good sealing and thermal conductivity, it is very suitable for foamed drinks that need to be aerated. However, it is inconvenient to carry the cans after opening, and it is also inconvenient to replenish water daily.

Let's take a look at glass bottle drinking water, which is also an uncommon drinking water package in the market.

Glass bottles are clear and transparent, have good visual effect, do not precipitate harmful chemicals, can be recycled, and are environmentally friendly, which is an enduring packaging method in the beverage market. However, the glass bottle is too heavy to stand the impact. Once they are broken, they are in danger of being scratched, which is not convenient for daily carrying. At the same time, some glass packaging materials may have hidden dangers of heavy metal lead pollution in the production process.

Finally, let's learn about the most common plastic bottled water.

Plastic bottles are cheap, light and strong, and are very popular with beverage merchants. At present, most plastic bottled water on the market adopts 1-PET plastic, which has low permeability to gas and water vapor, excellent gas, water, oil and odor resistance, oil resistance, acid resistance and dilute alkali resistance, and is often used in various food packaging. The maximum tolerance temperature of PET is 70℃, which is only suitable for warm or frozen drinks. If it is filled with high-temperature liquid or exposed to heat for a long time, it is easy to deform and there may be substances harmful to human body. However, if PP is used as a plastic bottle, the safety of drinking water after heating or exposure can be well solved. The melting point of PP material can be as high as 167℃, and it has good stability, portability and impact resistance, and can even withstand microwave heating.
