Sihaiwang: for pregnant mothers, I believe that many expectant mothers have prepared baby bottles in advance. For a baby, a milk bottle is a very important thing, because it's a guy for babies to eat. If the milk bottle is not selected properly, it also has a certain impact on the baby's milk, so what kind of material is it? How to choose a suitable baby bottle? Let's take a look at it with Xiaobian~
Characteristics of glass milk bottle
The characteristic of glass milk bottle is that the glass milk bottle is safe, without bisphenol A, and has high corrosion resistance and heat insulation performance. Glass milk bottle has good transparency and wear resistance. Even if it is permanent, the scale and bottle body will not be blurred.
However, there are two disadvantages of glass milk bottles, that is, they are heavy and fragile. Glass milk bottle has a certain thickness and weight, so the baby can't grasp stably, and it's easy to break compared with plastic milk bottle. At the same time, it should be noted that the expansion and contraction of heat will cause the glass to burst.
Characteristics of plastic milk bottle
There are many kinds of plastic materials, but PC (polycarbonate), PP (polypropylene), PES (polyethersulfone) and PPSU (polyphenylsulfone) are generally used to make milk bottles. Once PC material became the most popular material in plastic milk bottles because of its low price, good heat resistance and light weight. However, since the news that BPA in PC milk bottle is not good for baby's health appeared, PC can no longer be used as the material of milk bottle, instead of the safer PP, PES, PPSU and other new materials of milk bottle.
PES and PPSU are absolutely non-toxic, and they will not release toxic substances in the process of use. However, in terms of repeated disinfection capacity, PES and PPSU are about 100 times and 2000 times respectively, so PPSU is generally recommended, and the milk bottles of these two materials have honey color, which is their natural color, so there is no need to worry about the addition of colored powder. But the price of this material is too high.
However, the service life of PP milk bottle is only ten times. After more than one week, there will be problems. Because the maximum use temperature of PP is 107 ℃, long-term cooking and disinfection will reduce its use ability, but its price is cheaper, so there are still many people to choose.
Performance comparison of glass and plastic milk bottles
Heat resistance (deformation resistance): Glass & gt; PPSU = PES = PC & gt; PP
Washability: Glass & asymp; PPSU = PES & gt; PC & gt; PP
Strength: Plastic & gt; glass
Transparency: Glass = PC & gt; PPSU = PES & gt; PP
Characteristics of silicone rubber milk bottle
Silica gel milk bottle is made of liquid silica gel (LSR). It does not contain bisphenol A, does not break, and is soft. It is popular with parents. The silicone milk bottle has good stability and good elasticity between - 60 ℃ and 200 ℃. It can be placed for at least 1 year without deterioration under the conditions of room temperature 25 ℃, sealing, moisture free and high temperature free.
In addition, the silicone milk bottle has good chemical resistance, acid, alkali and a variety of chemicals, even if any disinfection method is used, it is not easy to deform, and it does not contain any harmful substances such as environmental hormones.
Moreover, the silicone rubber milk bottle is safe and non-toxic. Even if the silicone is placed at normal temperature, breast milk is not easy to deteriorate. If it is refrigerated or frozen, it can better maintain the freshness of breast milk. It can be used for a long time without changing the bottle, but it is difficult to clean the silicone bottle.
Characteristics of ceramic milk bottle
Among the numerous milk bottle materials, ceramic milk bottle is the healthiest, safe and non-toxic among the tableware materials, and has a certain thermal insulation effect compared with glass milk bottle. In addition to poor light transmittance and easy to break, other quality of ceramic milk bottle is better than other milk bottle materials. Ceramic milk bottles belong to the new product launched, which is not very popular, and the price is not cheap. Compared with other milk bottles, there are fewer parents who choose ceramic milk bottles.
Characteristics of stainless steel milk bottle
The advantage of stainless steel milk bottle is durable. As a durable material, stainless steel will not be broken or broken due to heat expansion and cold shrinkage. It can be used for 8-10 years generally. Moreover, it is easy to control temperature and contain no harmful ingredients such as BPA. In addition, stainless steel milk bottles are easy to clean, and milk stains on milk bottles are easy to wash.
As a common synthetic metal, stainless steel is also cheap. At the same time, it is also one of the recyclable metals, which is very environmentally friendly. However, as a relatively new member of the bottle material, stainless steel bottle, like ceramic bottle, is not the mainstream material at present.
Summary: glass milk bottle and ceramic milk bottle are more suitable for newborn use. The price of ceramic milk bottle is more expensive, and the difference between glass milk bottle and ceramic milk bottle is not very big, so it is enough to choose glass milk bottle. Plastic milk bottle is suitable for babies over three months. If possible, it is suggested to choose PPSU. Stainless steel milk bottle is suitable for babies over 1 year old, and the price is cheap. But because the stainless steel milk bottle is not transparent, we can't see how much milk is left in it, which is troublesome. Silicone milk bottle is suitable for babies of all ages. It has high cost performance and is suitable for mothers who are not afraid of trouble in cleaning.
