Wanna Kendall’s huge water bottle?Hold on,learn this first
Kendall appeared at the Los Angeles Stadium recently,the perfect figure wrapped in green tights and sweatshirts of the same color is very eye-catching. At the same time, the huge water bottle she carries around her waist also attracts people's attention. This novel and interesting way of drinking water has been longed by many people,hiking with huge bottle will become a new fashion.
There is no doubt about the importance of water. About 50-70% of a person's body weight is water. In the last century, there was a saying that people should drink eight glasses of water per day. In the past two years, FEMA also recommended that people drink 1 gallon of water a day. Outdoor fitness, hiking in the wild, and bringing your own water bottle have been very popular a few years ago, but the mini water bottle sometimes does not meet the demand after a long period of exercise, or lazying to fill water in the bottle. Therefore, the big kettle is needed.
But don’t rush to buy a huge water bottle,let’s learn more about it first.
At present, the most common large water bottles on the market are made of plastic, but the quality of different plastics is also very different. Some plastics may even contain BPA, which can cause breast cancer, prostate cancer, obesity, hyperactivity, Miscarriage, a variety of infertility and other diseases, so when choosing a water bottle, be sure to look at the recycling symbol on the bottom to judge the safety of the raw materials
"01"—PET (polyethylene terephthalate). It is often used to make mineral water bottles and beverage bottles，can resistant heat up to 70°C. so,it’s not suitable for holding hot water, heating or exposing to the sun, otherwise it may precipitate harmful substances to the human body. Recommendation: Throw away these bottles when they are used up, and do not use them as drinking water containers.
"02"—HDPE (High Density Polyethylene). It is often used to make plastic containers for detergent and bath products. Most of the disposable packaging bags used in supermarkets are made of HDPE. Features: It can withstand a high temperature of 110°C, and can be reused after careful cleaning, but it is usually not easy to clean the original detergent, and very easy to germinate bacteria. Recommendation: Don't use it to make water cups, don't use it to hold food.
"03"—PVC (Polyvinyl Chloride). It is often used to make shoes, raincoats, building materials, plastic pipes, etc., but is rarely used to make food packaging. Features: Excellent plasticity, low price, heat resistance up to 81℃. It is easy to produce harmful substances at high temperature, which is difficult to clean and easy to remain. Recommendation: Do not use this kind of plastic packaging for food, and it cannot be reused. If you need to use it, you should avoid it to be heat , and never use it as a drinking cup.
"04"—LDPE (Low Density Polyethylene) is often used to make cling film. Features: Not strong heat resistance. Generally, qualified PE cling film will melt when the temperature exceeds 110°C, leaving some plastic preparations that cannot be decomposed by the human body. In addition, when food is wrapped with plastic wrap and heated, the fat in the food can easily dissolve harmful substances in the plastic wrap. Recommendation: When using a microwave oven to heat food, first remove the wrapped plastic wrap.
"05"-PP (polypropylene). Often used to make microwave lunch boxes and water cups. Features: It is resistant to high temperatures of 130°C and has good thermal stability. It is the only plastic box that can be placed in a microwave oven and can be reused after careful cleaning. Suggestion: PP cups are already very reliable plastic cups, so you can use them with confidence. However, the body of some microwave lunch boxes is made of PP, but the lid is made of other materials, so special attention should be paid to remove the lid if necessary and then use the microwave to heat it.
"06"—PS (polystyrene). It is often used to make bowls of instant noodle boxes and foaming snack boxes. Features: Heat-resistant and cold-resistant, but cannot be placed in a microwave oven to avoid the release of chemicals due to excessive temperature. It is not resistant to acid and alkali substances. Polystyrene which is harmful to the human body will be decomposed in an acid and alkali environment, which is easy to cause cancer. Recommendation: Try to avoid using fast food boxes to pack hot food, do not use fast food boxes to hold acidic beverages such as orange juice, and do not heat the fast food boxes directly in the microwave.
"07"—PC and other categories. Commonly used to make milk bottles, space cups, etc. However, it has been controversial due to the presence of bisphenol A. The higher the temperature, the more bisphenol A remaining in the PC will be released. Recommendation: try to don’t use plastic cups made of PC.
So when choosing a water bottle, try to avoid choosing a PC material water bottle, but a lot of water bottles are not marked with material, or the markings are too complicated to easily distinguish whether it is safe or not. At this time you can take a look at the water flexible packaging.
The water flexible packaging is a stand up pouch, usually with a spout, so that it can be easily filled and poured. Although the water in the flexible packaging is also made of plastic, its safety is much higher than that of a water cup made of a single plastic injection.
The water spouted pouch is laminated of multiple layers of plastic, and each layer of plastic is responsible for different functions, so as to ensure both firmness and safety. General water spouted pouch is made of PA and PP. PA is a material with high mechanical strength. It is resistant to stretching, falling, high and low temperature, and puncture. Packaging made of this material can hold products up to 10KG or even 100KG. The PP materials are FDA-approved materials that can be directly contacted with food and will not cause toxicity, are colorless, odorless, and have excellent barrier properties that can block external oxygen and water vapor. , Bacteria, odor, etc. to keep the water pure. PP material is more transparent and more resistant to high temperature. PA is used on the outside to ensure firmness, and the inside is made of PP to ensure food safety. Such packaging bags are the most reassuring packaging.
The spout on the spouted pouch is also made of food-grade PP, which is safe and practical, and can facilitate the filling and pouring of water. The use of screw-on cap guarantees the reusability of the packaging bag. The bottom is a gusset that can be folded or unfolded. When you are not using it, fold the bottom, and the spout bag will become very flat. It does not take up space at all and is very convenient for storage. When you pour water into it, The bottom will unfold and you can stand on the table by its own, which is super convenient and beautiful.
And the plastic material used in flexible packaging is much less than that in rigid packaging. To make a package with the same volume of water, rigid packaging will use tens of grams or even hundreds of grams of plastic, but flexible spout bags only need to use a few grams, which greatly reduces the use of materials.
And rigid plastic bottles are not only heavier, but also take up a lot of space. When you go out, if you want to put a 1-gallon water bottle in your backpack, you don’t have to think about it. Since the flexible packaging is very soft, it can be transformed into various shapes with the surrounding environment, and it can be easily put into the backpack. And when you finish drinking the water inside, fold up the bottom, and the whole package will become as flat as paper, so you can easily take it back to free your hands.
If you are worried about the clumsy appearance of the flexible packaging and not fashionable enough, don't worry at all. Flexible packaging can be made into any shape that you think is interesting. Unlike rigid packaging, which can only be made into one shape, the expensive mold building fee also limits the development of packaging shapes. However, there is no need to worry about flexible packaging. Flexible packaging can be designed into any shape as long as you want, and you do not need to pay a high mold fee, the flexible packaging can be interesting and personalized.
All in all, the flexible packaging of water really achieves reduce, reuse and recycle.
