Here are some things to look out for when choosing bottled water:
Observe the appearance of the barrel: First, observe the appearance of the barrel and check whether the wall of the barrel is free of bubbles, whether the color is uniform, and whether the outer wall is smooth. The barrel (bottle) with better quality should be made of PC material (polycarbonate), with high transparency and smooth and clear surface, while the barrel made of waste garbage plastic is commonly known as "black barrel", which is black, dark and poor in transparency. In order to reduce costs, some manufacturers are still using this kind of packaged bottled water, which is expressly prohibited.
Check the bottom of the barrel mark: Manufacturers of regular barrels mostly write the name and logo of the manufacturer, material number, production date, etc. on the bottom of the barrel, but the "garbage can" does not. Special attention should be paid to two QS marks: one is that the label of bottled water must be affixed with the QS mark that conforms to the beverage market access system, and the other is that the bucket used must also have the QS mark of the bucket manufacturer, both of which are indispensable.
Check the seal: The heat shrinkable film at the fake water seal is generally thin, mostly blown by hair dryer, and the folds are uneven. The film of the real bottled water seal is thicker, the color and luster are strong, tight and smooth.
Check the color of the water in the bucket: Qualified drinking water should be colorless, transparent, clear, odorless, odorless, and not visible to the naked eye. Aquatic products with yellowish color, turbidity, flocculent precipitation or impurities, and peculiar smell must not be drunk.
Check the product label: The qualified product label should clearly indicate its product name, net content, ingredient list, manufacturer's name, address, production date, shelf life, product standard number, etc.
Choose a reliable brand: When buying bottled water, try to choose a reliable brand and distributor to ensure the safety and quality of the water source.
The above are the things you need to pay attention to when choosing bottled water, I hope it will help you.
