Infant water

It is inapposite for infants to drink pure water and filtered water from a water purifier. This type of water is clean, but it lacks trace elements that the body needs and long-term drinking will affect the growth and development of infants. Also, because of their weak digestive systems and inability to absorb many nutrients in mineral water, infants would better not drink mineral water. Therefore, infants are suitable for drinking high-quality mountain spring water with low mineralization and sodium, and high-quality tap water.

The elderly, patients water

We do not recommend for the elderly or patients to drink filtered and purified water from a water purifier. The old have a poor ability to absorb nutrients, and drinking water to supplement nutrients is one of the main ways. The elderly and patients have weak immunity and poor physical function, drinking water should be nourishing, healthy, and nutritious, suitable for drinking high-quality mineral water. High-quality mineral water can not only boost immunity and improve physical fitness, but it can also help with nutrition.

Tea water

In the long history of tea drinking, people summed up several criteria to judge good water: first, clear, that is, colorless and transparent, clear can see the bottom. Second, live water should flow. The third is light, which means soft water, because the magnesium and calcium ions in hard water are high, which leads to tea being dark and tasting bitter. The fourth is sweet, with sweet water quality. The fifth is cold, the ancient people advocated snow water to cook tea and believed that tea made with water that has gone through severe cold weather is more delicious.

The water for cooking tea

The essence of tea brewing is the chemical reaction between water and substances released by tea leaves, that is, the release of theanine, tea polyphenols, and other flavor substances.

When the water of small-molecular groups fuse with the tea leaves, can stimulate the sense of hierarchy of tea, making tea soup richer, tea flavor more mellow, taste more extreme, and lock fragrance sweeter, etc. Tea plants thrive in an acidic environment and are suitable for brewing with slightly acidic water. We recommend brewing tea with metasilicate natural mineral water rich in selenium, strontium, low deuterium, small molecular groups, vanadium, lithium, and low sodium.

Water quality requirement for different tea

Black tea is fermented tea. To make tea bright red, we recommend using water with a high TDS value (120-200).

Oolong belongs to semi-fermented tea, between green tea and black tea, so its mineral content can be slightly higher than green tea’s, a TDS of about 120 is better.

Green tea belongs to non-fermented tea, with high fragrance, mellow taste, beautiful shape, and brewing resistance. High mineral content will affect the color and aroma of tea soup. Water with a TDS of about 50 can better reflect the aroma and green color of the tea.

Which machines we need to produce large-size packaging water

Bottle preform is formed by an injection molding machine, which fills plastic particles into the mold at a specific temperature and pressure. Instead of purchasing injection molding equipment to produce bottle preform, new investors typically buy ready-made bottle preform. The weight of the bottle preform determines its costs. For instance, the 48mm caliber 5L bottle preform typically 90-100 grams. Bottle preform is an international standard part, that can buy locally or from other countries. At present, the price of bottle preform in China is. The cap price is per

Bottle design for large-size packaging water bottle

According to the shape of the bottle, the bottles have round and square bottles. According to whether there is a handle, bottles have handled bottles and ordinary bottles. In general, the square bottle requires a heavier bottle preform. The bottle preform is the main material cost of the beverage factory. How to reduce the weight of the bottle preform without affecting tee firmness of the bottles? When we design the bottles, in addition to selecting round bottles as far as possible, we can also use a short mouth and reinforcing ribs to achieve this.
