film tension in wrapper
At present, one of the methods to improve the performance of fpc1 is metallic resin. Because it is a multi-layer film combining lower cost and higher level metal layers, the competitive high performance stretch film can be created.
Fpc1 application also has two basic methods to apply fpc1 to load. Hand stretch film rolls are lighter and shorter than machine rolls, and are more convenient for users to use. In high-volume computing, the preferred method is the machine film, where fast and consistent packaging is needed. Machine wrapping with stretch film
Fpc2 requires an operator to complete the process, and the first thing he needs to do is fix the film on the load and then expand the fpc1 when he turns around. The tension required to apply the tension to the film also needs to be done by the operator so that sufficient packaging force can be ensured to accommodate and unify the load. Since the operation of the stretching film must be performed by the operator, the size and weight must be limited, which is limited to ease of use. Therefore, the width and length of the handbag are generally shorter, so that the weight can be limited. This approach is usually used only in low-volume applications
