As we all know, the
wrapping film is divided into two types: machine and hand. What is the difference between the machine wrapping film and the hand wrapping film?
1, different packaging methods
Suitable for hand stretch film, manual packaging: This package is the simplest one in wrapping film packaging. The film is mounted on a rack or held by hand, rotated by the tray or the film is rotated around the tray. It is mainly used for repackaging after the packaged tray is damaged, and for ordinary tray packaging. This packaging speed is slow, suitable film thickness is 15-20μm
Tray mechanical packaging by rotating the tray or rotating around the film, wrapping the film: This is the most common and widely used form of mechanical packaging. The film is fixed on the bracket and can be moved up and down. This packaging capacity is very large, about 15-15 per hour. 18 disks, suitable for a film thickness of about 15-25 μm.
2, different tensile strength
The
machine film is made of polypropylene mixed with metallocene, and the wound film is mostly a casting process. It has the characteristics of high tensile strength and good puncture performance. The stretching ratio is 2.5-4 times, the stretching ratio is 300%, and the product is stable, especially the film thickness is uniform, so the use of the wrapping film can ensure low unit consumption, thereby reducing the integration cost.
Easy to stretch,
hand-made film is made of polyethylene raw material or recycled material. The manual film stretching rate is 0-150%, and the price of the machine film and the hand film is 1-2 yuan per kilogram.
