Plastic flasks

 

— plastic, on the one hand, is notable for its low cost and light weight, on the other hand, it is quite practical and well suited for creating tourist and sports drinking containers. Such vessels are difficult to break or squash, and even in the worst case, if broken, plastic shards are much safer than glass. Plastic can be elastic and compress somewhat under pressure — this can be useful, for example, to increase the flow of fluid through a valve. In addition, plastic containers can be made transparent — the convenience of such containers is obvious. The disadvantages of this material are sensitivity to high temperatures and poor suitability for acidic and alcoholic drinks — upon contact with them, plastic walls can release harmful substances. In addition, we note that there are many different types of plastic on the market; as a result, some types of plastic may have additional restrictions on the use, and the overall quality of the material often directly depends on the price category of the vessel.

In general, the features of the use of plastic containers in each case should be clarified separately.
