Abstract
The invention discloses an outer packaging film for an instant noodle bowl and relates to the technical field of plastic films. The outer packaging film is prepared from, by weight, 40-50 parts of low-density polyethylene, 15-20 parts of polypropylene, 10-15 parts of medical stone powder, 8-12 parts of hydrogenated castor oil, 6-10 parts of microcrystalline cellulose, 6-10 parts of polyvinyl alcohol, 5-8 parts of casein-soybean glue, 4-6 parts of flexibilizer, 4-6 parts of sodium polyacrylate, 3-5 parts of carnauba wax, 3-5 parts of lauric acid monoglyceride, 2-3 parts of sorbitol, 2-3 parts of stearyl citrate and 1-2 parts of sodium stearyl fumarate. The packaging film is remarkable in mechanical performance, high in using safety, capable of externally packaging the instant noodle bowl after being stretched and excellent in sealing performance and weather resistance, the phenomenon that the quality of instant noodles is affected due to the fact that water and oxygen in air penetrate through the packaging film in the storage and shelf life is prevented, printing ink can be effectively attached to the packaging film, and therefore product information such as production dates and batches can be conveniently displayed.
Description
Technical field: [0001] The invention relates to the technical field of plastic films, in particular to an outer packaging film for an instant noodle bowl. Background technique: [0002] On the outermost layer of the instant noodle bowl, there is usually a layer of plastic film. The batch number and production date of the product are generally printed on this layer of plastic film. This layer of plastic film mainly plays the role of protecting product packaging. It meets the requirements of food grade, and there is no regulation in the national standard. As for paper cups, paper bowls or plastic cups, plastic bowls and other packaging materials that come into contact with food, the AQSIQ strictly requires that all materials and additives, including outer bags, must be It is food grade. In addition, white pollution still exists at present, and how to achieve biodegradability after use under the premise of ensuring the normal packaging performance of the film is still a rese...
