How to choose and apply machine wrapping film correctly

1、 Selection criteria for machine wrapping film
1. Material and thickness: Machine wound film is usually made of polyester (PET) or polypropylene (PP) material, which has good stretchability and tear resistance. When selecting, the appropriate thickness of wrapping film should be chosen based on factors such as the type of goods, weight, and transportation distance. Generally speaking, for heavy goods or goods that require long-distance transportation, thicker wrapping film should be selected.
2. Viscosity: The viscosity of machine wrapping film directly affects its effectiveness in fixing goods. Excessive stickiness may make it difficult for the film material to peel off, affecting packaging efficiency; If the viscosity is too weak, it may cause the goods to loosen during transportation. Therefore, when choosing, appropriate adhesive wrapping film should be selected according to actual needs.
3. Stretching rate: Stretching rate is one of the important indicators for measuring the performance of wrapping film. High stretch wrap can reduce the amount of film material used and lower costs while ensuring packaging effectiveness. Therefore, when choosing, attention should be paid to the stretch rate of the wrapping film and the selection should be based on actual needs.
4. Width and length: The width and length of the machine wrapping film should be selected according to the specifications of the packaging equipment and the size of the goods. Too wide or too long wrapping film may lead to waste, while too narrow or too short wrapping film may affect the packaging effect.
2、 Application scenarios of machine wrap film
1. Logistics transportation: Machine wrap film plays an important role in logistics transportation. It can tightly secure multiple goods together, preventing them from shifting, scattering, or being damaged during transportation. At the same time, the wrapping film can also prevent dust, moisture, and pollution, ensuring the safety of goods during transportation.
2. Warehouse management: In warehouse management, machine wrap film also plays an important role. It can be used to secure goods on pallets and prevent them from shifting or collapsing during storage. In addition, wrapping film can also be used to package scattered goods for convenient storage and handling.
3. Product packaging: Machine wrap film can also be used for product packaging. By wrapping the product in wrapping film, it can be protected from external environmental erosion, while increasing the product's aesthetics and attractiveness.
3、 Tips for using machine wrap film
1. Pre stretching: When using machine wrapped film, the stretching rate of the film can be increased by pre stretching, reducing the amount of film material used. Pre stretching can be achieved through specialized stretching mechanisms or manually operated.
2. Appropriate tension: When winding goods, appropriate tension should be maintained. Tight wrapping may cause the film material to break or the goods to deform; Loose wrapping may cause the goods to loosen. Therefore, the tension should be adjusted according to the actual situation during operation.
3. Cross wrapping: To improve the wrapping effect, cross wrapping can be used. First, wrap several layers of film material in one direction, and then wrap several more layers of film material in another direction. This can increase the friction between the film material and the goods, and improve the fixing effect.
4. Timely cutting: After winding is completed, the film material should be cut off in a timely manner. Excessive film material not only wastes materials, but may also affect the packaging effect. Therefore, during operation, it is necessary to ensure that the cutting position is accurate and neat.
