Do you know how to package stretch wrap film?

Stretch wrap film is also similar to wrap film, but when used, stretch wrap film can be applied to packaging with food. Usually, there is a clear state, and the clear wrapping film can easily distinguish what the packaging is, but if you want to use other colors. Can be customized. Packaging different things with different colors is also quite convenient. Do you know how to package stretch wrap film? Below, the editor of stretch wrap film will tell us about it.
The use of stretch wrap film in packaging is a well-known practice. Basically, it is used whenever goods are packaged. Firstly, due to its convenience, low cost, and good packaging effect, do you know how it is packaged? Generally, there are two methods for packaging: manual packaging and machine packaging. The stretch wrapping film used varies depending on the method used,
Firstly, we need to know that hand wound film is made of LLDPE and tackifier, and if it is used by machine, it needs to be added to MLLDPE. Therefore, in terms of price, machine used film is generally more expensive than hand used film. In addition, we can also explain the differences between them from the following two aspects:
1. Different packaging methods
Handmade packaging: This type of packaging is the simplest type of wrapping film packaging, suitable for hand stretching film. The film is placed on a rack or held by hand, rolled or wrapped around the tray. Mainly used for repackaging damaged pallets and general pallet packaging. This type of packaging is slow, and the appropriate film thickness is 15-20 μ M
Wrapped film tray mechanical packaging: This is the most widely used form of mechanical packaging, which is rotated by the tray or film wrapped around the tray, and the film is fixed on the bracket and can move up and down. This type of packaging has a great capacity, about 15-18 plates per hour. The appropriate film thickness is about 15-25 μ M.
2. Different tensile strength
The winding film is mostly produced by casting process, and the machine film is made of polypropylene mixed with metallocene, which has high tensile strength and good puncture performance. The stretching ratio is 2.5-4 times, the stretching rate is 300%, and the product is stable, especially with uniform film thickness. Therefore, the use of winding film can ensure low unit consumption, thereby reducing the cost of induction. Handmade films are made of polyethylene or recycled materials, which are easy to stretch. The stretching rate of handmade films is 0-150%. The price difference between machine and hand films is 1-2 yuan per kilogram.
