Description

Technical Field

[0001] The utility model relates to the field of medical sterilization packaging, and more particularly to a foldable medical sterilization paper-plastic roll bag with reinforced sealed edges. Background Art

[0002] Currently, medical sterilization paper-plastic roll bags on the market have a transparent plastic composite film on one side and medical dialysis paper on the other. They are also called paper-plastic bags. The two edges are connected by heat sealing and then rolled up to present in roll form. During use, the paper-plastic roll bag can be conveniently cut into any required length according to the length requirements of different items. After cutting, one end is sealed and hot-stamped to form a cavity with three sealed edges. After loading the items, the other end is sealed and hot-stamped. The transparent plastic composite film is airtight and has good antibacterial properties, while the medical dialysis paper facilitates the entry and exit of sterilization factors such as steam or ethylene oxide sterilization methods, while also preventing the invasion of microorganisms. Medical sterilization paper-plastic bags are popular among users due to their good visibility, strong antibacterial properties, long sterile validity period after sterilization, and ease of use.

[0003] However, the peel strength of traditional medical sterilization paper-plastic roll bags can only be controlled within a certain range due to the limitations of the performance of transparent plastic composite film and medical dialysis paper materials, as well as the requirement that no fiber paper scraps should be generated when peeled and opened for use. As a result, it is impossible to avoid the situation where the sealed edges of relatively large devices are prone to bursting during sterilization after packaging. In addition, the width of the paper-plastic roll bags is also greatly increased, which is not convenient for subsequent transportation and sterilization operations, resulting in certain restrictions on their application. Utility Model Content

[0004] The utility model aims to provide a foldable medical sterilization paper-plastic roll bag with reinforced sealed edges, thereby solving the problem that the sealed edges of traditional large medical equipment sterilization paper-plastic roll bags are prone to bursting during sterilization, making it inconvenient for later transportation and sterilization operations.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] Provided is a foldable medical sterilization paper plastic roll bag with reinforced sealed edges. The foldable medical sterilization paper plastic roll bag is formed by sealing and connecting a transparent plastic composite film and medical dialysis paper along both side edges and then winding them. A sealing adhesive strip is sandwiched between the transparent plastic composite film and the medical dialysis paper at the sealed connection. The width of the transparent plastic composite film is larger than that of the medical dialysis paper, thereby forming foldable portions on both sides for easy opening.

[0007] Preferably, the hot-sealing adhesive strip is hot-sealed and bonded to the medical dialysis paper to form a first hot-sealing and bonding connection portion, the width of which is equal to or slightly narrower than the material width of the hot-sealing adhesive strip; the transparent plastic composite film is hot-sealed and bonded to the hot-sealing adhesive strip to form a second hot-sealing and bonding connection portion, the width of which is smaller than the width of the first hot-sealing and bonding connection portion.

[0008] Preferably, the width of the transparent plastic composite film is 100 to 300 mm larger than the width of the medical dialysis paper.

[0009] Preferably, the width of the heat-sealing adhesive strip is 30 to 50 mm.

[0010] Preferably, the heat-sealing adhesive strip is made of a CPP film with a thickness of 40 to 60 μm.

[0011] Preferably, the transparent plastic composite film is formed by compounding a PET film with a thickness of 12 μm and a CPP film with a thickness of 35 to 55 μm.

[0012] Preferably, the medical dialysis paper has a gram weight of 60 g / m 2 ~80g / m 2 .

[0013] Preferably, the folded medical sterilization paper-plastic roll bag is rolled and stored around a roll core.

[0014] Preferably, according to the length requirements of different articles, the foldable medical sterilization paper-plastic roll bag is cut into required lengths and ironed along the bottom edge to form a foldable medical sterilization paper-plastic bag with reinforced sealed edges.

[0015] According to the utility model, based on the traditional medical sterilization paper plastic roll bag, a sealing adhesive strip made of the same material as the heat-sealed layer of the composite film is added to the sealed connection points along the edges of the transparent plastic composite film and the medical dialysis paper. After the sealing adhesive strip is sealed to the medical dialysis paper, the transparent plastic composite film is then heat-sealed and bonded to the sealing adhesive strip. Since the sealing adhesive strip has a large sealing surface with the medical dialysis paper, it prevents the transparent plastic composite film and the medical dialysis paper from bursting during sterilization of the medical sterilization paper plastic roll bag. In addition, in order to accommodate relatively large instruments in the sterilization paper plastic roll bag, only the width of the transparent plastic composite film material is increased, while the width of the medical dialysis paper material is not increased. The extended portion of the transparent plastic composite film forms a foldable portion that is easy to open, which can be folded and stored during sterilization and opened during use.

[0016] After the entire width of the hot-sealing adhesive strip is hot-sealed to the medical dialysis paper, the transparent plastic composite film is then hot-sealed to the hot-sealing plastic film of the medical dialysis paper. Because the heat-sealing layer of the transparent plastic composite film and the hot-sealing adhesive strip are made of the same material, the bond is extremely strong after hot-melt. The hot-sealing adhesive strip and the medical dialysis paper are also widened, significantly reducing the risk of bursting. Furthermore, the widened transparent plastic composite film is folded over before being rolled up, increasing the internal space within the medical sterilization paper-plastic roll bag, making it easier to load relatively large instruments.

[0017] The utility model provides a foldable medical sterilization paper-plastic roll bag with reinforced edges, i.e., a medical sterilization paper-plastic roll bag with reinforced edges and a folded portion, which has the following beneficial effects compared to the prior art:

[0018] 1) The sealing and bonding width of the two edges of the medical sterilization paper-plastic roll bag is increased, and the force direction during sterilization is also changed, reducing the risk of the sealing edge bursting due to sterilization;

[0019] 2) The transparent plastic composite film is widened, while the medical dialysis paper is not widened, which can improve visibility, increase the space for contents, and facilitate transportation and sterilization operations.

[0020] In summary, the foldable medical sterilization paper-plastic roll bag with edge reinforcement provided by the utility model has the advantages of not being easy to burst during sterilization, being convenient for later transportation and sterilization operations, through edge reinforcement and the addition of folding parts. It is particularly suitable for the sterilization of large-sized medical devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Combine Figure 1 、 Figure 2 As shown, a foldable medical sterilization paper-plastic roll bag with edge sealing and reinforcement is provided according to a preferred embodiment of the present invention, which is composed of medical dialysis paper 1, a transparent plastic composite film 2, and a sealing adhesive strip 3.

[0028] The foldable medical sterilization paper plastic roll bag is formed by sealing and connecting a transparent plastic composite film 2 and a medical dialysis paper 1 along the edges on both sides and then winding them up. The sealing adhesive strip 3 is sandwiched between the sealed connection between the transparent plastic composite film 2 and the medical dialysis paper 1. The width of the transparent plastic composite film 2 is larger than the width of the medical dialysis paper 1, thereby forming folding parts 41 and 42 on both sides for easy opening.

[0029] Medical dialysis paper 1, with a weight of 60g / m 2 ~80g / m 2 French medical dialysis paper.

[0030] The transparent plastic composite film 2 is composed of a heat-resistant layer 21 of PET (polyester film) and a heat-sealing layer 22 of CPP (polypropylene film), i.e., a PET / CPP transparent plastic composite film. The heat-resistant layer 21 is a 12 μm thick PET (polyester) film, and the heat-sealing layer 22 is a 35-55 μm thick CPP (polypropylene) film.

[0031] The sealing adhesive strips 31 and 32 are made of 40-60 μm CPP (polypropylene) film. Since they need to be heat-sealed and bonded to the medical dialysis paper and the transparent plastic composite film respectively, it is preferred to use a film made of the same material as the heat-sealing layer 22 of the transparent plastic composite film 2.

[0032] The heat-sealing adhesive strips 31 and 32 have a width of 30 to 50 mm. One side of the heat-sealing adhesive strips 31 and 32 is aligned with the two edges of the medical dialysis paper 1 and then heat-sealed to form first heat-sealing adhesive connection parts 51 and 52, respectively. The width of the first heat-sealing adhesive connection parts 51 and 52 is equal to or slightly narrower than the material width of the heat-sealing adhesive strips 31 and 32.

[0033] The width of the transparent plastic composite film 2 is 100 to 300 mm greater than that of the medical dialysis paper 1. The heat-seal layer 22 of the transparent plastic composite film 2 is heat-sealed and bonded to the heat-sealed adhesive strips 31 and 32. The edges are aligned and heat-sealed with the medical dialysis paper 1, forming second heat-sealed and bonded connecting portions 61 and 62, respectively. The width of the second heat-sealed and bonded connecting portions 61 and 62 is 8 to 15 mm. The portion of the transparent plastic composite film 2 that extends beyond the medical dialysis paper 1 forms folded portions 41 and 42 on either side. After heat-sealing and folding the transparent plastic composite film 2, it is then rolled onto a reel core 7 to form a medical sterilization paper plastic roll bag with reinforced edge sealing.

[0034] The medical sterilization paper-plastic roll bag with reinforced sealed edges provided in the above preferred embodiment is suitable for steam sterilization or ethylene oxide sterilization, and is particularly suitable for packaging and sterilizing relatively large devices of different specifications.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Various modifications are possible to the above embodiments of the present invention. Any simple, equivalent changes and modifications made in accordance with the claims and description of the present invention fall within the scope of protection of the present invention.
