Nylon bagging filmis a very tough film with good transparency, good gloss, high tensile strength and tensile strength, good heat resistance, cold resistance, oil resistance, organic solvent resistance, wear resistance, puncture resistance is good and relatively soft, oxygen resistance is good. To make sure nylon bagging film works, here are a few things to keep in mind when shopping:

1. Nylon bagging film's moisture absorption

Nylon bagging film when moisture absorption reaches 3%, the film will turn a light yellow color, and more than 3% will wrinkle. Therefore, nylon bagging film with low moisture content and slow moisture absorption must be used in ink printing. However, not all nylon bagging films have the same moisture absorption, with the same production process, thickness, time, and environment (same temperature and humidity), different nylon bagging film moisture absorption situation is not the same as yours, this time needs specific analysis of specific issues.

2. Thickness

Considering that when printing patterns, there is often a large area of field printing, if the material film surface average thickness tolerance is too large, easy to produce moisture absorption and drying inconsistent situation, thus affecting product quality, therefore, the average thickness tolerance of nylon bagging film should be under 6%.

3. Contraction rate

Nylon bagging film is smaller in longitudinal and transverse contraction, the difference between longitudinal and transverse contraction should not be more than 0.5%.

4. Film surface roughness (Surface finish)

Film Surface roughness is a hidden indicator of packaging film. Surface roughness is a comprehensive evaluation of the microscopic size characteristics of the thin film surfaces with small peaks and valleys at small distances.

Nylon bagging film is now widely used in the packaging market and is used in many industries. If you want to know more, please feel free to contact us.
