There are differences between PE film (polyethylene film) and PO film (polypropylene film) in terms of basic composition, physical properties and application.
Basic composition: PE film is mainly composed of polyethylene, which is often milky white and translucent, with certain mechanical strength and chemical stability.
PO films are polymerized from polypropylene monomer with good clarity and are often used in applications that require high light transmission.
Physical properties: PE film has good light transmittance and heat sealing performance, but the infrared transmittance is high, and its thermal insulation performance is weaker than that of some other film materials.
The PO film performs well in terms of transparency and haze, has high greenhouse light transmittance, and provides good defogging and dripping properties.
Applications: PE film is often used in the agricultural field, for example as packaging and covering materials, and its acid and alkali resistance and light transmittance are suitable for agricultural needs.
PO membranes are particularly suitable for the agricultural sector, especially where good light transmission, fogging and dripping capabilities are required, such as vegetable cultivation and flower cultivation.
Service life: PO film uses special antioxidants and light stabilizers, so it has a long service life, usually up to more than 3 years.
PE film also has a relatively long lifespan, but in sun conditions, it may need to be replaced once a year.
In summary, there are differences between PE film and PO film in terms of composition, physical properties and application fields. PE film is suitable for agricultural packaging and mulching, while PO film has better light transmission, anti-fogging and dripping properties in the agricultural field, and is suitable for occasions such as vegetable planting and flower cultivation.
