From the supermarket to buy bottles of mineral water and beverages, placed in a closed car in high temperature exposure over four hours, the results show, on the front windshield glass bottled water at the highest reaches 63 ℃, plastic bottles deformation. And on the car front, rear, rear windscreen place, such as the location of the trunk and drink water, the temperature is generally in the 40 and 50 degrees Celsius.

Car in summer temperatures and insufficient to cause the plastic to break down, the normal on the car does not pose a security hazard. In contrast, the high temperature to promote the propagation of microorganisms but easily overlooked by owners. Bottle deformation occurs, in fact, the processing residual stress release, the destruction of the microstructure is not, there is no decomposition of the plastic polymer.

According to reports, the International Bottled Water Association, the U.S. Food and Drug Administration (FDA) had also issued a corresponding statement explaining bottled water container in a variety of environmental conditions are safe, the so-called "Place in a hot car will precipitation of carcinogenic chemicals "argument and unfounded.

Kero to  Throttle Body   , although the car put the bottled water is not so terrible, do not panic, but it does not encourage people hoarding large amounts of water in the car. Because the general requirements of food from light as much as possible to avoid heat, light and high temperatures will accelerate the deterioration of the food quality and shorten the shelf life. Put bottled water in the car can only respond to emergency needs, but the amount is not large, often for new, sugary drinks, especially, to avoid deterioration.

Experimental sample: 330ml Blue Stream 2 bottles of drinking natural mineral water, 550ml Nongfushangquan natural drinking water 2 bottles of Minute Maid orange lemon flavored ice drink a bottle, unified Jasmine green tea drink a bottle, Minute Maid excellent milk Fruit drinks a bottle of milk, a bottle of Coca-Cola plastic bottles, cans of Coke a tank, were placed at the front of the car windshield, the car front seats, rear seat, rear windscreen place, trunk five different positions. These Bottled Water and Beverages on the packaging are labeled "avoid direct sunlight and high temperature, or placed in a cool dry place" and so prompt.

Plastics are polymeric materials, small molecule compounds that decompose to release temperatures of at least about 120 ℃, while the inside temperature is also not so far produce significant decomposition of the plastic bottle temperature.

In addition, even taking into account the synthesis in plastics processing residual impurities, the problem is not large. Qualified plastic bottle must comply with the mandatory standards "GB 13113-1991 food containers and packaging materials polyethylene terephthalate molding health standards", the standard on the water environment 60 ℃ soaking 0.5 hours leaching may substances in the presence of small molecules made limited, the regular manufacturers of PET bottle products, its residual few possible leaching of harmful substances is very small, is within the acceptable range.

And a packaged beverage filled with water at high temperatures does the bottle different, but this difference is not from the plastic bottle, but from the loaded things. Beverages can not be completely sterile, just put the number of bacteria at an acceptable level, high temperature environment conducive to the propagation of bacteria, easily lead to deterioration.

Sugary drinks and juices, there are a large number of bacteria necessary nutrients, but also easy to breed bacteria, so we want to avoid prolonged storage after opening. We sometimes feel a little bitter to drink these beverages, not because of the plastic, but the relationship between bacteria.

The label is to recycle PET labeling, the purpose is to facilitate the collection and sorting of plastics, because in our country is not mandatory labeling, so some do not bottle it is understandable, but the reality is that most plastic bottles are marked. It is emphasized that, PET plastic bottles are not heat-resistant limit temperature 70 ℃, PET material due to temperature changes in the crystal structure at least to above 130 ℃. Bottle experiment slight deformation appears, in fact, the processing of the release of the residual stress is not the destruction of the microstructure, there was no decomposition of the plastic polymer.

According  Throttle Body   to the throttle body Kero introduction, the car bottled water is not so terrible, is for the public to panic, said plastic bottles, but it does not encourage people to hoard a lot of water in the car. General food storage requirements from light as much as possible to avoid high temperature, because light and heat for the food quality is not good, but may accelerate deterioration, shortened shelf life. From this perspective, bottled water can be put in the car, to prepare for contingencies, but should pay attention to the amount not to big, shorten the storage time, often for new and avoid deterioration of the situation, especially sugary drinks.
