Affect the packaging with uneven thickness

If you pack, the phenomenon of the thickness because of what? We are in the process of production how to avoid the occurrence of this kind of phenomenon? To introduce below: 1, packaged with uneven thickness mainly raw materials melting state not average, resulting in the density and hardness is not the same, in the process of extrusion is prone to the status of the uneven thickness, if you want to avoid this situation, in the process of raw materials processing, completes the time and temperature control, ensure the melting of the raw materials are exactly the same. 2, also may be due to a machine, film extrusion machine production pressure cannot be stable, or the feed port and discharging port is the presence of foreign bodies, these will result in a high thickness uneven phenomenon. If you want to take quality guaranteed, the production check things out before you pack each item of equipment, in strict accordance with the standard to carry out, reduce mistakes.
