Take a rubber band and stretch it a bit longer. From now on, the remaining large amount of glue is related to the resistance of traditional stretch films (called "films" or "traditional films"). Now, stretch the same rubber band to the maximum without breaking-until there is almost no more elasticity-you will understand the advantages of pre-stretched film. There are few leftovers, which means fewer products go further, and the pressure on users is greatly reduced. Before the pre-stretched film is wound onto a roll for final use, it is stretched to near its final breaking point. This means that the film does not require as much user energy as standard films to achieve the same wrapping power. This is the main reason why pre-stretched films are so popular. In fact, with pre-stretched packaging, manual applications can create the same load stability as machine applications. The benefits of this are obvious. The manufacturer makes the pre-stretched film by mechanically stretching the pre-stretched film between 2 film carrier rollers. Since the surface of the second (larger) roller rotates faster than the first (primary) roller, the film is pulled between them and expands. The resulting rolls are generally light in weight and easy to handle, thereby reducing operator fatigue. Since the torque involved is small, users can also benefit from using forward wrapping technology to prevent slips and falls. In terms of material costs, Black Pe Stretch Film pre-stretched films are much thinner than traditional films. In the end, because operators use less materials during use, there is less environmental waste.
