Abstract
The invention relates to film production equipment and a preservative film. The film production equipment comprises a conveying device, a coating device, a leveling device, wherein the conveying device comprises a unwinding mechanism and a winding mechanism which are arranged at intervals; the coating device is arranged between the unwinding mechanism and the winding mechanism and comprises a feeding mechanism provided with a discharging opening and a coating roller, and the discharging opening of the feeding mechanism communicates with the roller surface of the coating roller; and the leveling device is arranged between the coating device and the winding mechanism and comprises at least one leveling roller, and the surface of the leveling roller is provided with a brush-like structure. The unwinding mechanism, the coating roller, the brush-like structure and the winding mechanism jointly form a coating channel used for conveying a film base layer. By means of the film production equipment, after a mould-proof preservative coating material is coated on the surface of the film base layer, the brush-like structure of the leveling roller is further used to evenly level the mould-proofpreservative coating material, the uniformity and density of the mould-proof preservative coating material are effectively improved, and defects such as hole shrinking, coating leakage or uneven coating caused by coating material leveling are avoided.
Description
technical field [0001] The invention relates to the technical field of films, in particular to a film production equipment and a fresh-keeping film. Background technique [0002] The storage conditions for fresh foods such as fruits and meat with a short storage period are relatively harsh, otherwise they will become moldy due to the proliferation of microorganisms, making them no longer fresh and losing their original value. The traditional method in the industry is to use desiccants and strong oxidants to achieve freshness preservation, create a relatively water-deficient environment through desiccants, inhibit the growth of mold, and kill mold with strong oxidants. However, strong oxidants are not friendly to the human body and the environment. While desiccant absorbs moisture in the air, it also absorbs moisture in the food, which in turn causes the problem of food dehydration. [0003] Therefore, in the field of food packaging in family life, supermarkets, hotels and r...
