Manufacturing method and characteristics of baby bottle
1. One-step plastic bottle feeding system for pediatric baby bottles , small mechanical trauma, good air tightness of bottles and caps, high leakage rate, high transparency, and beautiful appearance. The biggest technical doubt is that it is not easy to uniform the wall thickness of the bottle, large control, and easy to mutate.
2. Two plastic blow bottles, the mechanical scar line spans a step, transparency. Two-step foamed plastic baby bottle, preform injection molding and shaping, two heating and blowing in the next process. Preforms and warehouses in the hopper are stored to avoid mechanical hazards and preforms caused by conflicting preforms and damage to the preforms, which cause sealed bottle caps and poor households. Utilizing the advantages of this technique to blow bottles and inspecting them with an ultrasonic thickness gauge, the bottle wall thickness is uniform, the errors are small, and beer drinks are not prone to convexity.
3, the characteristics of disposable milk bottles , plastic, plastic milk bottles for beer and beverages, especially pay attention to whether all the lubricants meet the operating specifications, just maintain the specifications of the plastic milk bottles according to the lubricant is not caused by chemical hazards, otherwise, plastic bottles When filling and packaging, due to ultrasonic thickness lubricants with chemical hazards of high acid or high alkali, the storage bottle bursts or leaks or is transported together. This appearance is especially common in filling soda.
4. Pay attention to the baby bottle caps. The sealed metal cap is the most well-known metal cover information, such as the bottle seal is the use of metal aluminum caps, tight sealing, there will be no doubt about the seal. When the sealing cap is iron, it is particularly important to pay attention to the crown cap bottle and the red claw of the pressure-sealed metal cap. The metal cap is removed from the metal material due to mechanical rebound. If there is a rebound position, the sealing effect of the package is of course poor, but the light and heat and sensation of their packaging bottles will shorten or swell under the effect of external forces, which will cause the sealed place to leak the bottle and cap. Air formed by the filtrate leaked.
Is a disposable bottle safe?
The raw materials for disposable bottle manufacturers are PP (polypropylene) and polyethylene. PP (polypropylene) has high impact resistance, strong mechanical properties, and resistance to a variety of organic solvents and acid-base corrosion. It is widely used in industry and is one of the common polymer materials. Polyethylene has outstanding heat resistance and cold resistance, good chemical stability, high rigidity and resistance, and good mechanical strength.
Most of the disposable liners of disposable bottles are made of polyethylene, and the other parts are made of PP. PP raw materials are recognized in the world as safe materials for making food containers. They do not contain carcinogen bisphenol A.
Ensure the safety of raw materials.
The temperature resistance of disposable milk bottles is between minus 20 degrees and 110 degrees, and the brewing temperature of baby milk powder is in between, which is also suitable. Disposable liners have been sterilized and can be discarded after use without repeated use, reducing the possibility of bacterial growth.
Therefore, disposable bottles produced and tested by regular brands can be used safely and securely.
