Sequential vs. Simultaneous Biaxial Oriented Nylon Film
Simultaneous stretching The main points of the simultaneous stretching process are the water treatment tank, the primary film after cooling roller passes through water treatment tank before stretching, the film absorbs moisture and forms hydrophilic bond in 6 molecules, this weakens the hydrogen bond energy, making synchronous stretching possible. The structure of the water tank […]
What is Sequential Stretching?
Sequential stretching involves two steps: the first uses a machine direction oriented (MDO ) to stretch the material in the machine direction over a series of rollers, effectively increasing the length and decreasing the thickness of the web. In the second step, a transverse direction oriented (TDO) stretches the film or sheet perpendicular to the […]
