FIELD: sealing for nozzle holes.
SUBSTANCE: invention relates to thermoplastic polymer films, which close nozzle holes for ejecting liquids. Cartridge 220 for injecting liquids has head 222 of ejector, which head has at least one nozzle hole 224 and container 228 for liquid, which container has liquid to be ejected connected together though at least one nozzle hole. Cartridge for ejecting liquid has tape 200 which has film 202 made of thermoplastic polymer being in contact with nozzle holes. Method provides high strength of film, resistively to influence of liquid media. Film doesn't contain impurities, it has low speed of passage of water vapors and smoothly cover roughness on the liquid ejecting device. The film also provided ability of adjusting of adhesion properties due to application of different temperatures of sealing, pressure and time, which allows optimizing strengthening properties of protection films for different cartridges for liquid ejection.
EFFECT: higher degree of optimization.
