In the field of industrial packaging, stretch wrap film is a common consumable, and many users often notice the distinction between "hand use" and "machine use" in the product name when choosing. On the surface, the two have the same thickness and similar materials, but it seems that the only difference is in packaging specifications. However, the truly noteworthy technological differences do not lie in common parameters such as thickness or stretch rate, but in the operational methods targeted by product design - manual winding and machine winding pose completely different requirements for the physical properties, dimensional stability, and efficiency of the film. Understanding this design logic is the key to determining the applicable scenarios of the two solutions.

The core feature of PE plastic stretch wrap film is to emphasize the "customizable" width range (10-100cm) and the characteristics of "tear resistance" and "high adhesion, strong toughness, and not easy to break". From the perspective of production technology, this product also adopts extrusion stretching process, with a stretching degree of 500%, which is consistent with the latter. However, it is worth noting that the core material is paper tube core, and the packaging method is cardboard box packaging. This design is usually more inclined to meet diverse packaging needs, especially when users need different widths to adapt to different sizes of goods, customizable width becomes a practical feature. As a roll core, paper tube core is more common in manual operation because of its low cost and relatively low strength requirements for the roll core when manually tearing the film.
