Why stretch film standard width is generally 500 mm; thickness is generally from 0.015-0.05 mm(10-30 mic) range. Machine stretch film not more than 25kg, hand stretch film not more than 5kg. Core diameter and core length should meet the requirements of the corresponding specifications and need to be determined through consultation. The standard width of the stretch film is 50cm, the general manufacturers have this width of the stock, as for the other width can rarely do stock, this is why?
The width of 50cm is the most suitable width according to the operation habit of the Packer and the working efficiency in the process of winding the film, 50 cm is the optimal width, if too wide will be difficult to operate, and some people will think, then the width is not as narrow as possible?
The labor-saving point of view can be considered, but there is another problem, that is, work efficiency. For example, to pack a one-meter high carton, if you use 50 cm wide stretch film three or two times, if you use 20 cm, you need to wrap more than 5 times to pack. Therefore, the words of this calculation of packaging efficiency are much lower. Therefore, the width of 50cm is the best width for labor-saving and efficiency improvement, which is why the factory only uses this size to stock the most.
