Problems solved by technology

However, when using it to package some sharp medical devices, since the packaging film does not have tear resistance, during transportation, the medical device is easy to scratch the packaging film and contact with the outside air, which is unavoidable. Bacteria and viruses from the outside world will be adsorbed on medical devices through the air, causing pollution

Embodiment 1

[0042] refer to figure 1 , is a medical aseptic packaging film with tear resistance disclosed by the present invention, comprising a main body film 1 and a protective part 2 fixed on the periphery of the main body film 1 . Wherein, protective portion 2 comprises tear-resistant buffer layer 21, bacteriostatic coating 22 and release layer 23, and bacteriostatic coating 22 is fixed between tear-resistant buffer layer 21 and release layer 23, the thickness of protective portion 2 greater than the thickness of the main film 1. Further, the bacteriostatic coating 22 is uniformly coated by the SRB antibacterial coating, and the metronidazole bactericide is added in the SRB antibacterial coating, and the metronidazole bactericide SRB antibacterial coating has a strong ability to inhibit SRB bacteria on the coating surface The ability of adhesion and growth has very excellent antibacterial properties. The anti-tear buffer layer 21 is made of aluminum foil. The aluminum foil has good ...

Embodiment 2

[0049] refer to figure 1 , is a medical aseptic packaging film with tear resistance disclosed by the present invention, and its difference from Example 1 is that the tear-resistant buffer layer is made of PVC-UH material, and PVC-UH has high strength, High pressure, good toughness, and good impact resistance can effectively prevent medical devices from being scratched, thereby improving the tear resistance of the packaging film.

Embodiment 3

[0051] refer to figure 2 , a kind of medical aseptic packaging film production process with tear resistance, comprising the following steps:

[0052] S1, preparing the main body membrane 1: soaking the plant fiber powder, chitin, and diatomaceous earth in alkali solution, then filtering to take the filter cake, washing, and drying to obtain the fiber layer 13;

[0053] The ethylene acrylic acid copolymer material is heated and melted to form an adhesive layer 14, and the adhesive layer 14 is evenly coated on both sides of the nylon film layer 12, and then the PE resin film 11 and the fiber layer 13 are laminated on the nylon film layer 12, The thickness range of the nylon film layer 12 is controlled at 0.015-0.017mm;

[0054] S2, preparing the protective part 2: at a temperature of 250-255°C, melt the polyethylene material and evenly laminate it on the tear-resistant buffer layer 21;

[0055] After the side of the tear-resistant buffer layer 21 away from the barrier layer 2...

Abstract

The invention relates to a medical aseptic packaging film with tear resistance and its production process, wherein a medical aseptic packaging film with tear resistance comprises a main body film and a protective part fixed on the periphery of the main body film, The protection part includes a tear-resistant buffer layer, an antibacterial coating and a release layer, the antibacterial coating is fixed between the tear-resistant buffer layer and the release layer, and the thickness of the protection part is greater than that of the main film. The antibacterial coatings on the edge of the main film are attached to each other to ensure that the medical devices are not easily attacked by bacteria when they are stored, and have a good antibacterial effect. The anti-tear buffer layer increases the anti-tear performance and shock resistance of the packaging film, making it difficult for medical devices to pass through the packaging film and be polluted by the outside world. The protective thickness of the main film is greater than the thickness of the main film itself, so that its tear strength is increased several times or even dozens of times, thus effectively improving the overall tear strength of the medical aseptic packaging film.

Description

technical field [0001] The invention relates to the technical field of packaging films, in particular to a medical aseptic packaging film with tear resistance and a production process thereof. Background technique [0002] Medical plastic packaging film is widely used, not only for tablet, powder, granular medicine packaging, but also for paste, liquid and medicine carton packaging inner lining and medical equipment packaging, commonly used films include shrink film, winding Thin films, multilayer composite films, etc. In pharmaceutical packaging, glass bottles and plastic bottles used in the past are gradually being replaced by plastic films, especially plastic flexible packaging for medical liquids such as infusion bags, blood plasma bags, etc. are developing more rapidly. [0003] In the prior art, the Chinese patent with the authorized announcement number CN207791610U discloses a high-barrier antibacterial food packaging film. The high-barrier antibacterial food packagi...
