Problems solved by technology

When the sterilization bag is in use, the user needs to cut one end of the sterilization bag with scissors to take out the medical devices inside. However, particles are likely to be generated during the process of cutting the sterilization bag, which will affect the environment of the clean area. Particle pollution is generated. In view of this, it is necessary to improve the traditional sterilization bag and its preparation process

Embodiment 1

[0024] see figure 2 , the top of the connecting strip 4 coincides with the top of the first sheet layer 1, and is used for the preparation process of a sterilization bag for reducing particles in a clean environment, including the following steps:

[0025] S1, the polyethylene material roll and the Dupont Tyvek material roll are respectively cut into the first sheet layer 1, the second sheet layer 3 and the connecting strip 4 of the corresponding size;

[0026] S2. Correspondingly connecting the fourth hot-melt connection part 5 at the bottom of the connection bar 4 with the third hot-melt connection part at the top of the second sheet layer 3 through hot melting, so as to connect the second sheet layer 3 and the connection bar 4 on the Together, a second mixed flake layer is obtained;

[0027] S3. Correspondingly connecting the first hot-melt connection part of the first sheet layer 1 and the second hot-melt connection part 2 of the second hybrid sheet layer through hot mel...

Embodiment 2

[0030] see image 3 , the distance between the top of the connecting strip 4 and the top of the first sheet layer 1 is 5 cm, and the preparation process for a sterilization bag for reducing particles in a clean environment includes the following steps:

[0031] S1, the polyethylene material roll and the Dupont Tyvek material roll are respectively cut into the first sheet layer 1, the second sheet layer 3 and the connecting strip 4 of the corresponding size;

[0032] S2. Correspondingly connecting the fourth hot-melt connection part 5 at the bottom of the connection bar 4 with the third hot-melt connection part at the top of the second sheet layer 3 through hot melting, so as to connect the second sheet layer 3 and the connection bar 4 on the Together, a second mixed flake layer is obtained;

[0033] S3. Correspondingly connecting the first hot-melt connection part of the first sheet layer 1 and the second hot-melt connection part 2 of the second hybrid sheet layer through hot...

Abstract

The invention discloses a sterilization bag for reducing particles in a clean environment. The sterilization bag comprises a first sheet layer and a second mixed sheet layer; first hot melt connectionparts are arranged at the two sides and the bottom of the first sheet layer correspondingly; second hot melt connection parts are arranged at the two sides and the bottom of the second mixedsheet layer correspondingly; the first hot melt connection parts and the second hot melt connection parts are correspondingly connected by hot melting so as to connect the first sheet layer and the second mixed sheet layer together and form an opening inthe top end; the second mixed sheet layer comprises a second sheet layer and a connection strip; a third hot melt connection part is arranged at the top ofthe second sheet layer; and a fourth hot melt connection part is arranged at the bottom of the connection strip and correspondingly connected with the third hot melt connection part by hot melting. The sterilization bag has good puncture resistance, tear resistance and microbial barrier performance, and can effectively avoid particle generation, so that particle pollution to the clean area environment is avoided.

Description

technical field [0001] The invention belongs to the technical field of sterilization bags, and in particular relates to a sterilization bag for reducing particles in a clean environment and a preparation process thereof. Background technique [0002] Bacteria bags can be used for medical or medical disinfection and sterilization. Suitable sterilization methods include EO ethylene oxide sterilization, high temperature and high pressure steam damp heat sterilization, cobalt 60 radiation sterilization, and commonly used medical devices are packed into packages The bag is then sealed and sterilized. Among them, the moist heat sterilization method refers to the method of sterilizing with saturated water vapor, boiling water or circulating steam, using high-temperature and high-pressure steam as the medium, due to the large latent heat of steam and strong penetrating power, it is easy to denature or coagulate proteins, eventually leading to The death of microorganisms, so the ste...
