Sealing & Handle:
Polypropylene film is a high - strength, wear - resistant white smooth film.It has medium permeability to water, gas and smell, but is not affected by the change of external humidity.It has extensibility, but not as good as polyethylene.It is better than HDPE film in blocking, especially in dampness and water resistance, while the peculiar smell and gas (such as oxygen) transmission rate are still larger, and can be improved by uv penetration, composite or coating.It has better tensile strength and rigidity than other films (such as PE and PET) at similar prices.
Polyester (PET) film has high application value in packaging. It is the strongest type of film with excellent comprehensive performance, but its only drawback is that it is expensive and high melting point makes hot sealing difficult.
Polyester (PET) films are rarely used alone on packaging, but are often used in composite substrates, especially those that are stretched or bidirectional, and are ideal for high performance films.
