CPE film is a plastic film made of chlorinated polyethylene (CPE). CPE is a synthetic resin with excellent chemical corrosion resistance and heat resistance, as well as good tensile strength and tear resistance. This makes CPE film an ideal packaging material, widely used in industries such as food, medicine, and cosmetics.
In addition to food packaging, CPE film is also widely used in pharmaceutical packaging. Drug packaging requires good sealing and waterproofing to protect the quality and safety of drugs. CPE film has good sealing performance, which can effectively prevent drugs from being damp and oxidized. At the same time, CPE film also has excellent waterproof performance, which can prevent the drug from coming into contact with external moisture, maintaining the stability and effectiveness of the drug. In addition, CPE film also has good chemical corrosion resistance, which can prevent the interaction between drugs and packaging materials.
Cosmetic packaging is also one of the important application fields of CPE film. Cosmetic packaging requires good moisture and oil resistance to protect the quality and stability of cosmetics. CPE film has excellent moisture-proof performance, which can effectively prevent cosmetics from getting damp and deteriorating. At the same time, CPE film also has excellent oil resistance, which can prevent cosmetics from coming into contact with external oils and maintain the texture and effect of cosmetics. In addition, CPE film also has good transparency and glossiness, which can enhance the appearance effect of cosmetics.
In addition to the main uses mentioned above, CPE films can also be applied in fields such as agriculture and industry. In the agricultural field, CPE film can be used as a preservation film for agricultural products, extending their shelf life. In the industrial field, CPE film can be used as a protective film to protect products from external damage and pollution.
The process of producing CPE films typically includes the following steps:
Firstly, it is necessary to prepare the raw materials. CPE resin is the main raw material for making CPE films, usually mixed with other additives (such as plasticizers, stabilizers, etc.) in a certain proportion.
Secondly, the raw materials need to be processed through melt extrusion. Put the mixed raw materials into the extruder, heat and melt them to extrude them into thin films. The extruder is usually composed of a heating zone, a melting zone, and an extrusion port. By controlling temperature and extrusion speed, the required film thickness and shape can be obtained.
Next, the extruded film needs to be cooled and solidified. Quickly cool the extruded film through a cooling device to cure it. Cooling devices usually use cooling rollers or water cooling systems to ensure the curing speed and quality of the film.
Then, the cured film needs to be stretched and adjusted. By stretching treatment, the thickness and tensile strength of the film can be adjusted to meet different application requirements. Stretching is usually carried out through stretching rollers or stretching machines, with multiple stretches as needed until the desired film performance is achieved.
Finally, the adjusted film needs to be cut and packaged. Cut the film and package it according to the required size and shape for easy use and sales.
In summary, CPE film is a plastic film made of chlorinated polyethylene, which has excellent chemical corrosion resistance and heat resistance, and is widely used in packaging in industries such as food, medicine, and cosmetics. The production process of CPE film includes the steps of raw material preparation, melt extrusion, cooling and curing, stretching adjustment, cutting and packaging. Through these process steps, CPE films with good performance can be manufactured to meet the packaging needs of different industries.
