| titleOfInvention | Dry-wet separation mask bag and preparation method thereof |
| abstract | The invention belongs to the technical field of facial mask packaging bags, and aims to solve the problem that the existing dry-wet separation facial mask bag is opened only by locking a dry-wet separation port through a plastic buckle and requiring at least 20N of operating force, the invention provides a dry-wet separation facial mask bag and a preparation method thereof, the facial mask bag is prepared by oppositely arranging two aluminum foil bodies and then carrying out heat sealing, wherein the aluminum foil bodies are sequentially provided with a printing material layer, an aluminum foil layer and an inner sealing material layer from outside to inside along the facial mask bag, the inner sealing material layer is made of biaxially oriented polyethylene (PPE), the heat sealing pressure is 0.59N-0.69N, the heat sealing temperature is 140-150 ℃, and the heat sealing rotating speed is 25-27 r/m, the middle parts of the two aluminum foil bodies are heated and pressurized, so that the two inner sealing material layers form a facial mask bag interrupted area, and the pressure of the interrupted area of the obtained facial mask bag is 5-10N, therefore, an operator can, the packaging is convenient to use, and no potential safety hazard exists when the packaging is opened. |
