Properly purchase and use plastic water bottles to avoid potential hazards.

- Mar 23, 2019-

In some supermarkets, children's plastic water bottles with various colors displayed on the shelves are mostly unmarked, and consumers generally only choose the capacity and style of plastic water bottles. Few people pay attention to the material and safe use of plastic water bottles.

 

In view of the potential hazards of plastic products to human health, a consumer warning is issued for this purpose:

First, plastic water bottles can not be reused for a long time, cautious use of plastic water bottles filled with hot water.

The second is to look at the material of the plastic water bottle. The identification method is to put the bottom of the plastic water bottle up and see a triangle symbol with three arrows. There are 1-7 numbers in the triangle. Each number represents a different material. Although this labeling method is not mandatory, in order to facilitate the recycling of plastic products, large and medium-sized enterprises generally label plastic recycling labels. Therefore, when consumers choose plastic containers, they must choose the products of large enterprises first.

Digital ID 1 indicates that PET (polyethylene terephthalate), mineral water bottles, carbonated beverage bottles are made of this material, heat-resistant to 70 ℃, high temperature liquid or heated easily deformed, harmful substances will dissolve.

 

Digital ID 2 indicates HDPE (High Density Polyethylene), which is often used to produce white medicine bottles, cleaning products and bathing products. At present, most of the plastic bags used in supermarkets are made of this material, which can withstand high temperature of 110 ℃, Plastic bags for food can be used to hold food.

Therefore, consumers are reminded to remove the wrapped film before putting food into the microwave oven.
