The Following Is The Production Process Of Bubble Film Manufacturing

First, raw material preparation
The main raw material of bubble film is polyethylene, and various additives need to be added. These raw materials need to be prepared before making bubble film. Under normal circumstances, manufacturers will buy polyethylene particles and additives, after measurement, mixed products.
Second, extrusion molding
The core of making bubble film is extrusion molding. The extruder processes raw materials into continuous bubble film through three processes of plasticizing, extrusion and cooling, the process is as follows:
1. Plasticizing: the polyethylene particles are added to the hopper of the extruder, and the particles are molded into extrudable melt under the condition of high temperature and pressure.
2. Extrusion: the plasticized melt extrusion machine head, driven by the die head, extrusion molding bubble film.
3. Cooling: the extruded bubble film is cooled by the cooling roller at a certain speed.
Third, finished product production
After extrusion and cooling, the finished bubble film is ready for production. The production process is as follows:
1. Cutting: the wide bubble film will be cut into the required size and quantity according to the customer's order requirements.
2. Composite: the bubble film and other materials are composite, such as PE film, mesh cloth, etc.
3. Processing: The bubble film is processed, such as folding, embossing, punching, etc.
Iv. Summary
The production process of bubble film manufacturing includes raw material preparation, extrusion molding, cooling, finished product production and other links, of which extrusion molding is the core link of making bubble film. Through careful operation and continuous technological innovation, the bubble film manufacturing process has become more and more mature and can meet the various needs of customers.
