Problems solved by technology

The existing technology includes coating hot melt on the paper, which avoids direct heat sealing between the plastic film and the paper, but the air permeability of the paper coated with hot melt is greatly affected
Then change to grid-shaped glue; but this kind of hot melt has poor temperature resistance, and the bag may burst in the general sterilization process; later, water-soluble glue appeared, which has a certain effect on the application of temperature. greatly improved
But whether it is hot-soluble glue or water-soluble glue, there are certain residues

Embodiment Construction

[0011] Below, according to the accompanying drawings, preferred embodiments of the present invention are given and described in detail, so that the functions and features of the present invention can be better understood. The disposable medical sterilization packaging ziplock bag of the present invention is a packaging product used for one-time sterilization, is suitable for sterilization methods such as ethylene oxide and formaldehyde, and can play a protective role after sterilization.

[0012] Such as figure 1 As shown, the disposable medical sterilization packaging ziplock bag is composed of two layers of materials, the upper and lower sheets, including the upper plastic film 1 and the lower plastic film 2. The three side edges of the upper plastic film 1 and the lower plastic film 2 are ironed together. Its opening 3 is not ironed on the side.

[0013] Wherein upper strata plastic film 1 is punched with air vent in advance, and the purpose that has air vent on the plasti...

Abstract

The invention relates to a disposable medical sterilization packaging self-sealing bag, which comprises an upper layer plastic film and a lower layer plastic film which are sealed together by heat, and one side is provided with an opening, wherein, the upper layer plastic film is provided with air holes, the outer surface of the upper layer plastic film is also provided with a layer of creped paper, and the lower layer plastic film is a stripping composite film of epoxy polyester (PET) plus polyethylene (PE). The disposable medical sterilization packaging self-sealing bag has better packaging bearing effect and no paper scraps in the opening process of the package, thus achieving more secure opening. The packaging self-sealing bag can be widely used for sterilization anti-virus packaging of medical instruments, and provide protection after sterilization.

Description

technical field [0001] The invention relates to a ziplock bag, in particular to a disposable medical sterilization packaging ziplock bag. Background technique [0002] The sterilization ziplock bag used for packaging medical devices must meet the air permeability of the packaging material so that the sterilization medium can penetrate the packaging material. At the same time, it must have a biological barrier function, withstand its sterilization conditions and ensure the sterility of the packaged items. In addition, during the sterilization process, the packaging material should not release any harmful substances, the packaging material should have sufficient strength to prevent damage during sterilization, it must be able to prevent the possibility of being re-contaminated, and the sterilized item must comply with the aseptic method when it is opened. After opening, the article should not be contaminated by the non-sterile outer surface, or by the release substances (fiber...
