What are the commonly used plastic films?

Plastic granulator manufacturers provide: the commonly used plastic film is 1. Polyethylene film (PE), 2. Polyvinyl chloride film (PVC), 3. Polystyrene film (PS), 4. Polyester film (PET), 5. Nylon, 6. A polypropylene film (PP), etc.

PE film is a colorless, odorless, odorless, translucent non-toxic insulating material, used in a large number of bags; food bags can also be made into a variety of containers. It is an inert material, so it is more difficult to print and must be processed before it can print better results. For this PE film, Puri uses a horizontal water ring pelletizing system that is easy to operate. Compared to several other plastic films, this PE film is easier to recycle after all.


PP film has good gloss and good transparency, heat-resistant acid and alkali, solvent resistance, friction resistance, tear resistance, and gas permeability. It cannot be heat sealed when it is lower than 160 °C. Puri uses a vertical water ring pelletizing system.

PVC film has good light resistance and aging resistance and has good tear resistance. It is breathable. It is a clean, colorless and transparent film. It is usually added with a plasticizer. It is soluble in acetone and ring. A solvent such as a ketone. Therefore, it can be printed with an ink made of a polyvinyl chloride resin. Suitable for packaging bags, book covers, etc.

PS film is a soft and tough film, clean, colorless and transparent. When it is free of plasticizer, the film is always soft, resistant to freezing, and stored without aging. The oxidative polymerization of synthetic binder ink can be used for printing. Good degree.

PET is colorless, transparent, moisture-resistant, air-tight, soft, strong, acid-base oil ester and solvent, and is not afraid of high and low-temperature materials. After EDM treatment, it has better surface fastness to ink. Used in packaging and composites.

Nylon film is stronger than polyethylene film, odorless, non-toxic, impervious to bacteria, oil, ester, boiling water, and most solvents. It is generally used for load-bearing, wear-resistant packaging, and retort packaging (reheating of food) It can be printed without surface treatment.

The performance of various plastic films is different, the degree of difficulty in printing is also different, and the use as a packaging material is also different. If you want to know more about plastic machinery, you can log in to the following website.
