What is the difference between hand wrapping film and machine wrapping film?

At present, the stretch film on the market mainly uses LLDPE as the raw material, so that the stretch film produced has the characteristics of good tensile properties, strong retraction force, high transparency, good puncture resistance, good self-adhesion and low unit consumption. Whether it is used for product collection packaging or cargo pallet packaging, it can achieve the purpose of preventing moisture and dust, reducing labor, improving efficiency and reducing costs.
At present, the stretch film on the market is mainly divided into two types: hand-use and machine-use. Generally, the stretch film is made of LLDPE and a tackifier, and if machine-use is used, MLLDPE must be added. Therefore, machine-use stretch film is better than hand-use. Stretch film is more expensive, which is also the difference between them! Take a look at the other differences:

Different tensile strength
Most of the stretch film manufacturing process, the machine film is made of polypropylene mixed with metallocene, which has the characteristics of high tensile strength and good puncture performance. The stretching ratio is 2.5-4 times, the stretching ratio is 400%, and the product is stable, especially the film thickness is uniform, so the application of the stretch film can ensure low unit consumption, thereby reducing the overall cost.
The hand film is made of polyethylene raw material or recycled material, which is easy to stretch. The stretch rate of the hand film is 200%-300%. The price difference between machine film and hand film is 0.5-1 yuan per kilogram.
Different packaging
Manual packaging: This kind of packaging is a simple type of wrapping film packaging, suitable for hand stretch film, the film is loaded on a rack or hand-held, and the film is rotated by the tray or the film is rotated around the tray. Mainly used for repackaging after the packaged pallet is damaged, and ordinary pallet packaging. This type of packaging is slow, and the suitable film thickness is 15-20 μm.
Pallet Mechanical Packaging of Stretch Film
This is a common and widespread form of mechanical packaging, where the tray rotates or the film rotates around the tray, and the film is fixed on a support and can move up and down. This packing capacity is large, about 15-18 trays per hour. A suitable film thickness is about 25 μm.
