Summary
In the entire packaging process of skin film manufacturers, the static electricity of plastic film consists of two parts: the static electricity inherent in the plastic film itself and the static electricity generated by friction during the packaging process. The static electricity inherent in the plastic film is easy to control, but the static electricity generated during the packaging process is more difficult to control.
Food skin film. The static electricity of plastic film can cause electrostatic adhesion, which negatively affects laser cutting, transportation, and stretching of plastic film, leading to common malfunctions during machine operation. Therefore, if only the static electricity value of the plastic film itself is focused on while ignoring the static electricity generated during the packaging process, the plastic film may have excellent inspection characteristics but will frequently malfunction during machine operation.
Anti-static properties are one of the basic standards to ensure smooth packaging. The vast majority of food skin films require excellent anti-static properties to avoid electrostatic adhesion caused by the unwinding of plastic film (thin and soft transparent sheets) and friction with machinery. Therefore, anti-static is one of the basic characteristics required for purchasing skin film.
Purchasing skin film. Generally, on automatic packaging machines, static electricity can migrate quickly through metal or static eliminators. In addition, environments with high humidity are also beneficial for removing static electricity from the surface of plastic film. When encountering plastic film with relatively high static electricity or during dry (low moisture) seasons, manufacturers can pre-place the plastic film in the packaging workshop, adjust the humidity of the packaging workshop, or choose to spray water on the factory floor or place wet cotton towels inside the film roll core to increase environmental humidity, which helps remove static electricity from the surface of the plastic film. Purchasing skin film.
Skin film manufacturers know that the greater the direct reflection of light on the surface of the plastic film, the higher the glossiness. High-gloss surfaces concentrate the light source and can clearly reflect images; low-gloss surfaces scatter light in all directions, reducing image quality. Therefore, the surface of food skin film should have a high surface flatness, and higher glossiness can create a beautiful visual impact on cigarette packaging. Purchasing skin film.
Skin film manufacturers define haze as clarity, which accurately measures the percentage of scattered light deviating from the direction of transmitted light beyond a certain viewing angle. At small viewing angles, the packaged contents are clearer; large and inconsistent transmission angles cause reduced saturation.
