Description

Technical Field

[0001] The utility model relates to a medical sterilization package, and more particularly to a medical sterilization paper-plastic bag. Background Art

[0002] Currently, medical sterilization paper-plastic bags on the market typically feature medical dialysis material on one side and medical plastic film on the other. Three edges are sealed and bonded together to form a cavity. The fourth edge, unsealed, forms the bag opening, and the sealed area opposite the bag opening forms the bag bottom. Medical dialysis material offers excellent bacteria-blocking properties while facilitating the entry and exit of sterilization media. Once medical instruments and items are sealed, the bags, depending on their material composition, can be sterilized using pressurized steam, ethylene oxide, or other sterilization methods, maintaining the sterilized instruments and items for a specified period of time.

[0003] Medical paper-plastic bags offer numerous advantages, such as excellent antibacterial properties, a long shelf life after sterilization, visibility, and easy packaging, making them highly popular with users. However, after sterilization, these bags must be opened by peeling the plastic film away from the dialysis material. This requires both ease of opening and a lack of fiber and paper debris. Therefore, the peel strength at the seal between the plastic film and the dialysis material must be controlled within a certain range. Excessive peel strength can easily generate fiber and paper debris during opening; too little peel strength can easily lead to bag bursting during loading or sterilization. This is particularly true at the bottom of the bag, which bears the heavy load and is therefore more susceptible to bag breakage. Utility Model Content

[0004] In order to solve the problem in the prior art that the bottom of the bag is prone to breakage due to load bearing, the utility model provides a medical sterilization paper-plastic bag.

[0005] According to the utility model, the medical sterilization paper-plastic bag is composed of a medical dialysis material, a first composite film and a second composite film, wherein the first ends of the first and second composite films are flush and spaced apart to provide a bag opening, the first composite film is folded to provide a bag bottom opposite to the bag opening, the second end of the first composite film is folded over the medical dialysis material and is sealed and bonded to the first end of the medical dialysis material to form a first sealed edge, the second end of the second composite film is located above the medical dialysis material and is sealed and bonded to the second end of the medical dialysis material to form a second sealed edge, and the opposite sides of the medical dialysis material are sealed and bonded to the first and second composite films to form a third and fourth sealed edges respectively.

[0006] In a preferred embodiment, the first composite film is composed of a stacked first temperature-resistant layer and a first heat-sealing layer. The first heat-sealing layer is arranged above the first temperature-resistant layer facing the medical dialysis material. The first end of the first composite film is one side of the bag opening. The second end of the first composite film is folded toward the first heat-sealing layer. The folded first heat-sealing layer is overlapped with the first end of the medical dialysis material and sealed and bonded to form a first sealed edge.

[0007] In a preferred embodiment, the folded width of the first composite film is 20 mm to 25 mm.

[0008] In a preferred embodiment, the second composite film is composed of a stacked second temperature-resistant layer and a second heat-sealing layer. The second heat-sealing layer is arranged below the second temperature-resistant layer facing the medical dialysis material. The first end of the second composite film is the other side of the bag opening. The second heat-sealing layer at the second end of the second composite film is overlapped with the second end of the medical dialysis material and sealed and bonded to form a second sealed edge.

[0009] In a preferred embodiment, the total width of the second composite film is 50 mm to 60 mm.

[0010] In a preferred embodiment, the second end of the second composite membrane reserves a peeling opening edge when overlapping the medical dialysis material.

[0011] In a preferred embodiment, the width of the peeled open edge is 10 mm to 15 mm.

[0012] In a preferred embodiment, the widths of the first, second, third and fourth sealing edges are 6 mm to 10 mm respectively.

[0013] In a preferred embodiment, tear openings are formed on the third and fourth sealing edges.

[0014] In a preferred embodiment, the distance between the tearing opening and the bag opening is 20 mm to 25 mm.

[0015] According to the medical sterilization paper-plastic bag of the utility model, the bag bottom uses a folded plastic film instead of the medical dialysis material and the plastic film sealed and bonded as the load-bearing point, which greatly increases the load-bearing capacity of the paper-plastic bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a top view of a medical sterilization paper-plastic bag according to a preferred embodiment of the present utility model.

[0017] Figure 2 yes Figure 1 Cross-sectional view of . DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings and described in detail.

[0019] like Figure 1-Figure 2 As shown, the medical sterilization paper-plastic bag according to the present invention is composed of a medical dialysis material 1, a first composite film 2 and a second composite film 3, wherein the right ends of the first and second composite films 2 and 3 are flush and spaced apart to provide a bag opening 4, the first composite film 2 is folded to provide a bag bottom 5 opposite to the bag opening 4, the left end of the first composite film 2 is folded over the medical dialysis material 1 and is sealed and bonded with the left end 10 of the medical dialysis material 1 to form a first sealed edge 6, the left end of the second composite film 3 is located above the medical dialysis material 1 and is sealed and bonded with the right end 11 of the medical dialysis material 1 to form a second sealed edge 7, the front and back sides of the medical dialysis material 1 are sealed and bonded with the first and second composite films 2 and 3 to form third and fourth sealed edges 8 and 9 respectively.

[0020] Unlike the prior art where the plastic film and the medical dialysis material are flush, in the medical sterilization paper-plastic bag of the present invention, the plastic film surface of the first composite film 2 is extended and folded, then overlapped with the medical dialysis material 1 and then sealed and bonded. The newly added second composite film 3 overlaps the medical dialysis material 1 and then sealed and bonded. The original plastic film and the medical dialysis material are sealed and bonded together in opposite directions, but are changed to being sealed and bonded together in overlapping directions. The direction of force applied to the plastic film and the medical dialysis material is changed after the plastic film and the medical dialysis material are bonded together, greatly improving the load-bearing capacity of the bag bottom. In particular, the bag opening 4 is a plastic film-to-plastic film seal, making it easier to seal and bond the same material, and also improving the peel strength after sealing. The bag bottom 5 uses a folded plastic film instead of the medical dialysis material-to-plastic film seal as the load-bearing point, greatly increasing the load-bearing capacity of the paper-plastic bag.

[0021] The first composite film 2 is composed of a stacked first heat-resistant layer 21 and a first heat-sealing layer 22. The first heat-sealing layer 22 is disposed above the first heat-resistant layer 21, facing the medical dialysis material 1. The right end of the first composite film 2 forms the bag opening 4. The left end of the first composite film 2 is folded toward the first heat-sealing layer 22, forming the bag bottom 5. The folded first heat-sealing layer 22 overlaps the left end 10 of the medical dialysis material 1 and is heat-sealed to form a first heat-sealed edge 6.

[0022] The folded width of the first composite film 2 is 20 mm to 25 mm, that is, the extended length of the first composite film 2 behind the bag bottom 5 is 20 mm to 25 mm.

[0023] The second composite film 3 is composed of a stacked second heat-resistant layer 31 and a second heat-sealing layer 32. The second heat-sealing layer 32 is disposed below the second heat-resistant layer 31, facing the medical dialysis material 1. The right end of the second composite film 3 is the other side of the bag opening 4. The second heat-sealing layer 32 at the left end of the second composite film 3 overlaps the right end 10 of the medical dialysis material 1 and is heat-sealed to form a second heat-sealed edge 7.

[0024] The total width of the second composite film 3 is 50 mm to 60 mm.

[0025] Among them, the left end of the second composite membrane 3 reserves a peeling opening edge 12 when overlapping the medical dialysis material 1, that is, the left end of the second composite membrane 3 extends beyond the second sealing edge 7, which is convenient for grasping when peeling and opening, and the second composite membrane 3 can be peeled off.

[0026] The width of the peeling opening edge 12 is 10 mm to 15 mm, that is, the distance between the left edge of the second composite film 3 and the second ironing edge 7 is 10 mm to 15 mm.

[0027] The widths of the first, second, third and fourth sealing edges 6, 7, 8 and 9 are respectively 6 mm to 10 mm.

[0028] The third and fourth sealed edges 8 and 9 are formed with tearing openings 13 , so that the composite film sealing the bag opening can be torn off from the tearing openings 13 when the bag is opened.

[0029] The distance between the tearing opening 13 and the bag opening 4 is 20 mm to 25 mm.

[0030] Thus, according to the medical sterilization paper-plastic bag of the present invention, the plastic film surface of the first composite film 2 is extended relative to the plastic film in the prior art. The extended plastic film is folded toward the heat-sealed surface. The folded portion forms the bag bottom 5, which is the primary stress point of the medical paper-plastic bag. The folded first composite film 2 is overlapped, sealed, and bonded to one end of the medical dialysis material 1. The other end of the medical dialysis material 1 is shorter than the plastic film surface of the first composite film 2. The shorter portion is overlapped with the second composite film 3. The overlapped second composite film 3 is flush with the first composite film 2 to form the bag opening 4 of the paper-plastic bag. The two vertical edges of the bag opening 4 are sealed and bonded to form a cavity connected to the bottom on three sides. Furthermore, the opening method of the medical sterilization paper-plastic bag of the present invention can be determined according to actual needs. The plastic film can be peeled off from the breathable material by peeling off the opening edge 12 reserved near the overlap of the plastic film and the medical dialysis material near the bag opening, or the plastic film can be torn off from the tearing edge 13 on the sealed and bonded edge near the bag opening to open.
