1, to ensure the reliability of the wrap-around film packaging machine parts.
For key parts, should plan and calculate the central part of the parts subjected to alternating stress of the load, strength stiffness and fatigue limits, and test verification to improve the operational reliability of the winding machine parts.
2, wrap-around film packaging machine cutting and welding parts, and the appropriate addition of cast parts.
3, reduce the wrap-around film packaging machine non-standard parts plan to increase the use of common parts.
4, pay attention to the reliability of the connection between the parts of the wrap-around film packaging machine plan.
5, pay attention to the wrap-around film packaging machine benchmark.
To sum up, stretching the stretch film before the wrapper can not only improve the tensile properties, but also change its puncture resistance and viscosity.
