What is the difference between thermoplastic PO film and non-thermoplastic PO film?

Thermoplastic PO film and non-thermoplastic PO film are two different types of polyethylene film, they have some differences in physical properties, processing technology, application fields and so on.

First, thermoplastic PO film is a film made from polyethylene by melting extrusion and stretching. This film has good thermoplasticity and can be processed into various shapes, such as films, bags, cups and so on, at a certain temperature and pressure. Thermoplastic PO film has good flexibility and ductility, which is suitable for packaging food, daily necessities, medical products and so on. In addition, because the thermoplastic PO film can be sealed by hot melt adhesive, high frequency welding, etc., it has a wide range of applications in the packaging industry.

Non-thermoplastic PO films, also known as cold plastic PO films, are films made by a special polymerization process. Compared with thermoplastic PO films, the processing process of non-thermoplastic PO films is more complex and requires special cooling and curing processes. Non-thermoplastic PO film has good rigidity and tensile properties, and is not easy to deform, which is suitable for making some packaging containers with special shapes, such as bottle caps and bottle bodies. In addition, non-thermoplastic PO film in moisture, moisture, oxidation resistance and other aspects of the performance is also good, widely used in food, cosmetics, medicine and other industries.

The difference between thermoplastic PO film and non-thermoplastic PO film is not only reflected in the processing technology, but also in the physical properties. First of all, the thermoplastic PO film has good flexibility and ductility, and can be deformed within a certain range without breaking. The non-thermoplastic PO film is relatively brittle and hard, and is not easy to deform. In addition, the thermoplastic PO film has good transparency and gloss, and the surface is smooth, while the non-thermoplastic PO film is relatively cloudy and the surface is rough.

In the field of application, thermoplastic PO film has been widely used in the packaging industry and manufacturing field because of its good flexibility and ductility and wider applicability. Non-thermoplastic PO film due to its better rigidity and tensile properties, suitable for the production of some special shape packaging containers, such as bottle caps, bottles and so on.

In short, thermoplastic PO film and non-thermoplastic PO film are two different types of polyethylene films. Thermoplastic PO film has good flexibility and ductility, simple processing technology and wide applicability. The non-thermoplastic PO film has better rigidity and tensile properties, and the processing technology is complex, which is suitable for making special shape packaging containers. They have certain differences in physical properties and application fields, and different film materials can be selected for use according to specific needs.
