Dong Golden Lion: drinking water safety and the environment Packaging Solutions
Water is indispensable to the main body of material, water loss of 20% of people that have life-threatening. 80% of human diseases related to drinking. With the rapid economic, human over-exploitation of water resources, waste and destruction caused by the global water crisis. Increasingly serious water pollution in China has a lot of eating with drinking water, exacerbated the water crisis.
As society progresses, people's living standards improved, increasing water demands, a variety of water followed. However, the water we drink is safe, whether health, whether the standard of science, how to solve drinking water problems in the end, etc., also need further exploration and research.
And water quality and safety are closely related to the various chemical substances and the safety of packaging materials, resources and environmental issues and other issues require careful thought and scientific research. Food Packaging Equivalent to the concept of security has gained recognition for food safety, water, and the fate of the future will be packing interests and the community should attach great importance.
Tap water may be present in our lives most of the water used. As the quality of our water, transportation pipelines and storage tanks there are many problems and so I turned on the tap water faucet can not be directly consumed, must be boiled or treated before drinking, which promoted the huge China market structure changes to drinking water , various water-related equipment, technologies, products and concepts highly popular and hot copy. However, in the long run, Drinking water Issue should be resolved through the protection of water sources, the update of public drinking water facilities, upgrading of water treatment technology and the concept of drinking water to achieve the proper guidance, by drinking bottled water, packaged water, bottled water, etc. can not fundamentally solve the daily drinking water, they might bring drinking water health, social harmony and environmental issues, multiple disasters.
A drinking water safety and the environment Packaging
Regardless of what kind of water is inseparable from the packaging, whether it is bagged, bottled, bottled or bowl, box, therefore, directly affect the safety of packaging by the packaging of water safety. A variety of packaging waste will bring a range of resources and environmental issues, if they can not reasonably resolved, will affect the development of enterprises of various drinking water.
(A) qualified water packaging may be a problem.
The current bucket and a variety of mineral water and pure Beverages Most bottles are manufactured from food grade PET. PET, learn the name of poly ethylene terephthalate, in English called Polyethyleneterephthalate, colorless, transparent, room temperature, odor, widely used in beverage, food, Cooking oil Area. Formal enterprises in the bottom of the bottle or the barrel will have a code "1" logo.
PET bottled water is water, PET bottles and Plastic cover Composition. Of water, colorless and tasteless, slightly soluble in which some element of smell, it'll not drink tastes. A lot of research and testing to prove: water odor is coming from the packaging materials, mainly:
1, high temperature odor. Although the packaging material at room temperature, and tasteless, but higher than 38 in long cases, packaging materials easy to volatile odors small molecules, migration into the water, odors.
Formed by the polymer material and HDPE PET materials are sensitive to temperature, typically the higher the temperature, the greater the odor. As a part of residual polymer in low molecular weight substances, at high temperatures, it volatile odor greater than the polymer. Should be avoided in the high temperature transport and storage, effectively prevent odor generation.
2, in the sunlight odor.
Packaging materials has joined the anti-UV substances, but under the conditions of exposure, some residues in the polymer chain end groups of low molecular weight substances can easily be activated to produce small amounts of degradation products, soluble in water, odor, if coupled with high temperature, smell more noticeable.

This is a strangely written article. However, I use filtered tap water which I drink out of a Stainless Steel Water Bottle.
