Relatively speaking, nylon film is stronger than polyethylene film and can be printed without surface treatment. Resistant to dilute acids and most solvents, resistant to oils, esters, boiling water, odorless, non-toxic , impermeable to bacteria.
It has low air permeability, moisture permeability and odor permeability, and the moisture permeability is better than that of polyethylene film. When it is above -50C, it is soft, does not contain plasticizer, and is very stable under normal temperature and humidity.
Nylon film has relatively good insulation and is suitable for use at medium and low voltages. It melts at 215C, resists high temperature of 180C, does not soften, and can be heat-sealed at high temperature. Therefore, high-frequency .
It is generally used for heavy-duty, durable packaging and hot-boiled packaging (food reheating).
