Embodiment 1

[0079] A single-layer polypropylene porous film with a thickness of 120 μm and a porosity of 75% was prepared by the melt stretching method, and it was used as the upper layer 1 and the lower layer 2 of the medical sterilization packaging material at the same time, and the two were sealed by heat sealing. Connect to obtain the airtight cavity 3. The lower layer 2 is provided with a rectangular hole, and the upper layer 1 is provided with an EO sterilization indicator mark 6 . Some polypropylene porous films were selected to measure air permeability, porosity, tensile strength, puncture strength, average pore size and melting point. The results are shown in Table 1.

Embodiment 2

[0081] A three-layer polypropylene porous film with a thickness of 20 μm (total thickness) and a total porosity of 45% is prepared by a melt stretching method, which is used as the upper layer 1 and the lower layer 2 of the medical sterilization packaging material at the same time, and is sealed by heat sealing. The two are connected by means of a closed cavity 3 . The lower layer 2 is provided with a rectangular hole 5 , and the upper layer 1 is provided with an EO sterilization indicator mark 6 . Some three-layer polypropylene porous films were selected for measurement of air permeability, porosity, average pore size, tensile strength, puncture strength and melting point. The results are shown in Table 1.

Embodiment 3

[0083] A polypropylene / polyethylene / polypropylene porous composite film with a thickness of 12 μm (total thickness) and a total porosity of 60% is prepared by a melt stretching method, which is used as the upper layer 1 and the lower layer 2 of the medical sterilization packaging material at the same time, The two are connected by means of heat sealing to obtain an airtight cavity 3 . The lower layer 2 is provided with a rectangular hole 5 , and the upper layer 1 is provided with an EO sterilization indicator mark 6 . Some polypropylene / polyethylene / polypropylene porous composite films were selected to measure air permeability, porosity, average pore size, tensile strength, puncture strength and melting point. The results are shown in Table 1.

Abstract

The invention discloses a medical sterilizing packaging material capable of efficiently sterilizing. The packaging material has high air permeability, relatively high mechanical strength, very high microbial barrier performance and sterilizing agent resolving performance. A polyolefin porous film layer is introduced into at least one layer of the medical sterilizing packaging material, so that theobtained medical sterilizing packaging material has ventilation and bacteria blocking characteristics and superior air permeability; smooth penetration of a sterilizing agent during sterilizing is ensured; and the sterilizing agent can be resolved rapidly at the end of the sterilization. The material used is low in production cost, has relatively high mechanical strength, prevents bag blasting during sterilization, and does not tend to be damaged during storage and transportation. Meanwhile, the medical sterilizing packaging material has very high microbial barrier performance, and prevents sterilized products from suffering from secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of medical sterilization packaging materials, and in particular relates to a medical sterilization packaging material capable of high-efficiency sterilization. Background technique [0002] At present, the commonly used sterilization methods in the field of medical sterilization include EO sterilization, irradiation (gamma ray) sterilization, high-temperature steam sterilization, and low-temperature formaldehyde sterilization. Among them, EO sterilization is one of the most important low-temperature sterilization methods at present. EO sterilization can kill various microorganisms such as spores, Mycobacterium tuberculosis, viruses, fungi, etc. at room temperature. It has strong penetrability and can be used for sterilization of various difficult-to-permeable parts, and is widely used in the field of medical sterilization. When EO is used for sterilization, special medical sterilization packaging materials ...
