With the continuous growth of the stretch wrap film market, more and more products are packaged with stretch film, which is due to the good tensile performance, strong retraction force, high transparency, good puncture resistance, good self-adhesion and low unit consumption of the stretch film.
In general, the stretch film on the market is divided into two types: manual and machine. Generally, the stretch film is made of LLDPE and tackifier, while if it is machine-used, MLLDPE must be added. In addition to the difference in manufacturing materials, let’s take a look at other differences:
Different tensile strength:
Most stretch films are made by cast film manufacturing process, and machine-used films use polypropylene mixed with metallocene, which has the characteristics of high tensile strength and good puncture performance. The stretching multiple is 2.5-4 times, the stretching rate is 300%, and the product is stable, especially the film thickness is uniform, so the use of stretch film can ensure low unit consumption, thereby reducing the overall cost.
Manual stretch film is made of polyethylene raw materials or recycled materials, easy to stretch, and the stretching rate of handmade film is 0-150%. The price difference between machine film and hand film is 0.3-1 yuan per kilogram.
Different packaging methods:
Manual packaging: This packaging is the simplest type of stretch film packaging, suitable for hand-held stretch film. The film is mounted on a rack or held by hand, and the pallet rotates or the film rotates around the pallet. It is mainly used for repackaging after the wrapped pallet is damaged, and ordinary pallet packaging. This packaging speed is slow, and the suitable film thickness is 15-20?m
Pallet mechanical packaging of stretch film: This is the most common and widespread form of mechanical packaging. The object to be wrapped is placed in the middle of the turntable. By starting the turntable motor, the turntable is driven to rotate, and the stretch film is naturally evenly wrapped on the surface of the object. At the same time, the elevator motor is also started, driving the stretch film rack to move up and down, so as to achieve the film wrapping in the height direction of the object, which realizes the wrapping packaging of the entire surface of the object. This packaging capacity is very large, about 15-18 trays per hour. The suitable film thickness is about 15 to 25 μm
Different scopes of use:
Machine-used stretch film is suitable for customers with large usage. It is generally recommended to use machine-used stretch film, which can reduce the labor of workers; and machine-used stretch film is tighter than manual stretch film, and one person can complete all actions using machine-used stretch film.
Hand stretch film is to wrap scattered products firmly into a whole, so as to improve the efficiency of handling and avoid scattering and loss. The advantage of using manual stretch film is that it can be used anytime and anywhere, and there is no need to move it to a certain location for packaging. The use area is small, and it is suitable for customers with small usage and customers with limited production areas.
Whether it is machine-used stretch film or hand-used stretch film to package products, it can achieve the purpose of moisture-proof, dust-proof, improving efficiency and reducing costs. Of course, whether you need machine-used stretch film or hand-used stretch film, you can buy it on Baozheng Packaging.com, and the product quality is guaranteed, and the product after-sales service is more in place!
