Genuine milk storage bags are safe milk storage bags are mainly made of polyethylene, also commonly known as PE, which is one of the most widely used plastics. Some milk storage bags are labelled as LDPE (low density polyethylene) or LLDPE (linear low density polyethylene) which are both types of polyethylene, just with different densities and structures, but without much difference in terms of safety. Some milk storage bags also include PET to make it a little better barrier. There is nothing wrong with any of these materials per se, it’s all about whether the additives are safe or not. Many people are afraid of adding BPA to plastic products. BPA is indeed toxic, and products made from polycarbonate molecules may release BPA under certain temperature conditions, but polyethylene and PET do not have this problem. Nowadays, products are usually marked whether they contain BPA or not.
In fact, the bag is cracked because of the poor performance of the material used in low temperature, low temperature becomes brittle, easy to crack after the force. The reason for the odour of milk storage bags, fresh bags are usually sterilised using radiation, a high-intensity particle beam that kills bacteria while also leaving an odour.
In addition, the oxidation of the surface of PE in order to obtain a sufficient adhesion of the printed ink on the surface can also create an odour. If some of the molecules in the milk have changed, it is possible that some material has entered the milk, such as particles dispersed into the milk, creating a special structure that will give it colour. This type of milk is recommended not to be consumed again.
It is best not to recycle milk storage bags because the molecules of the plastic itself are in motion and have a wide range of movement, so that something can stick to them and these things can change in quality; it is not possible to wash plastic products completely. Therefore the safety risk increases with recycling.
The key to storing breast milk is in the freezing method and not in the milk storage bag. If they are not used properly, breast milk is still at risk of being destroyed.
Once the milk has been placed in the breast milk storage bags malaysia, expel the air from the bag and seal it with a seal. Keep frozen in the fridge for up to 6 months. Before use, thaw in the freezer and warm with warm water. Finally, unseal and pour into a bottle for feeding to the baby. The whole process is free from possible contamination by bacteria in the fridge.
