prospect of biodegradable pet bottles is widely used in daily necessities and easy to use. Do you know the production process of prospect of biodegradable pet bottles? The following Xiaobian will give you a simple explanation, let's have a look.

prospect of biodegradable pet bottles has the characteristics of unbreakable, low cost, high transparency and food raw materials. prospect of biodegradable pet bottles are mainly made from materials such as polyethylene or polypropylene and add a variety of organic solvents. prospect of biodegradable pet bottles widely used polyester (PET), polyethylene (PE), polypropylene (PP) as raw materials, after adding the corresponding organic solvent, after high temperature heating, through the plastic mold after blow molding, extrusion blowing, or injection molding plastic containers. So how exactly is the prospect of biodegradable pet bottles produced?

One is the extrusion and blowing process, which is to add the plastic raw materials to the extruder, melt and plasticize and extrude the molten billet, and then put it into the bottle mold to blow and form, and remove it from the mold after cooling and fixing the waste edge to get the finished product. This process is mainly used to produce polyethylene, polyvinyl chloride prospect of biodegradable pet bottles, such as milk bottles, soy sauce bottles and so on.

The prospect of biodegradable pet bottles with one-step blowing method has the advantages of less mechanical scars, good air tightness between bottle mouth and bottle cap, small air leakage and water leakage ratio, high transparency and beautiful appearance. The technical problem is that it is not easy to control the uniformity of the bottle wall, the thickness difference is large, and it is easy to produce convex deformation.

There is also a process of injection drawing and blowing, which means that the plastic raw materials are injected into the tubular blank by the injection molding machine, and then put into the bottle mold by stretching and blowing molding, and the finished product is obtained after cooling. This process is mainly used to produce PETprospect of biodegradable pet bottles, such as mineral water bottles.

The prospect of biodegradable pet bottles produced by two-step blowing method has more mechanical scars and less transparency than that by one-step blowing method. The prospect of biodegradable pet bottles is firstly prefabricated and shaped by injection molding, and then sent to the next process for secondary heating and blowing. In the process of hopper transfer and storage, it is inevitable that the mechanical trauma and the damage of the bottle and the mouth caused by the friction between the bottle and the mouth, so the air tightness of the bottle cap and the mouth is poor, and the air leakage rate is higher than that of one-step blowing. Its advantage is that the bottles blown out by this technology are tested by ultrasonic thickness meter, and the walls of these bottles are uniform, the thickness error is small, and it is not easy to produce convex deformation after filling beer beverages.

When processing the specified prospect of biodegradable pet bottles, the manufacturer shall follow the appropriate treatment methods and means during the working period. To ensure the quality of production and good performance in the processing process.

The above is about the prospect of biodegradable pet bottles of the production process to explain, read everyone know, I hope to help you.
