As shown in fig. 2 and 3, the sterilization bag 1 is manufactured by respectively covering the edge sealing films 102 on both sides of the reflective film 101, wherein the distance between the edge sealing films 102 covering both sides is the bag width of the sterilization bag 1, cutting the length of the reflective film 101, folding the reflective film 101 back and forth at the middle folding line 103 of the length of the reflective film 101, wherein the upper end or the lower end of the folding line 103 forms the front 104 or the rear 105 of the sterilization bag 1, forming the sterilization bag 1 by performing hot pressing or pressurization on both sides at the front and rear edge sealing films 102, and performing automatic sealing process treatment on the opening part of the sterilization bag 1.
The reflective film 101 is a PET film as a substrate, and one method is a film having a metal reflective effect, that is, a metallized PET film, which is formed by depositing aluminum on the surface of a PET film by using a multi-layer metal sputtering technique, and is also an aluminum-plated film.
The material of the reflective film can also be selected as follows: PMMA, PC and PVC (the reflective membrane is generally divided into six layers, namely a high-permeability membrane layer, a glass bead layer, a focusing layer, a radiation layer, an adhesive layer and a stripping layer, wherein the high-permeability membrane layer determines the service life of the reflective membrane, the layer of the glass beads directly determines the reflective strength of the reflective membrane, and the reflective membrane is provided with glass beads, prisms and diamonds).
The hot-press forming of the PET film into the sterilization bag 1 requires a layer of edge sealing film 102, and usually a PE film or cpp film is coated on the PET film, and the front and back surfaces of the PE film or cpp film are hot-pressed to form a bag edge sealing structure. However, this technique results in a layer of PE film or cpp film and adhesive layer on the front and back inner surfaces of the bag 1, which absorb ultraviolet light with wavelength of 260nm to 280nm, and thus, the power consumption of the sterilizer 2 is seriously affected or the sterilization time is prolonged.
The ultraviolet light source of the sterilizer 2 is 265nm LED or 275nm C-section ultraviolet LED, and the price of each ultraviolet LED is several yuan under the condition of low power. Therefore, the light reflection rate of the light reflection film 101 is improved to the maximum, especially the light reflection rate of ultraviolet light with the wavelength of 260nm to 280nm, the cost can be greatly reduced, and the one-time service time of the battery is prolonged.

The substrate of the light reflecting film 101 is a PET film, and the second method is to form an ultraviolet reflecting film that reflects 80% or more of ultraviolet rays by using a vacuum technique and an ion technique, and to reflect only the ultraviolet rays and partially reflect visible rays.
Similarly, a layer of edge sealing film 102 is required for hot-pressing the PET film to form the sterilization bag 1, and a PE film or cpp film is usually coated on the PET film, and the front and back surfaces of the PE film or cpp film are hot-pressed to form the bag edge sealing structure. However, this technique results in a layer of PE film or cpp film and adhesive layer on the front and back inner surfaces of the bag 1, which absorb ultraviolet light with wavelength of 260nm to 280nm, and thus, the power consumption of the sterilizer 2 is seriously affected or the sterilization time is prolonged.
The ultraviolet light source of the sterilizer 2 is 265nm LED or 275nm C-section ultraviolet LED, and the price of each ultraviolet LED is several yuan under the condition of low power. Therefore, the light reflection rate of the light reflection film 101 is improved to the maximum, especially the light reflection rate of ultraviolet light with the wavelength of 260nm to 280nm, the cost can be greatly reduced, and the one-time service time of the battery is prolonged.
