Blister packaging is a packaging method that seals the product between a blister formed by a transparent plastic sheet and a bottom seal (made of cardboard, plastic film or sheet, aluminum foil, or a composite of these). Double aluminum foil is widely used in the pharmaceutical packaging industry.

[0003] However, the existing pre-packaged double aluminum foil has the following problems when used:

[0004] When the double aluminum film is pressed open to remove the tablet, the lack of a guide results in small portions of the double aluminum film remaining at the opening, causing unevenness and affecting the user's perception. Therefore, this application proposes a pharmaceutical packaging composite film. Utility Model Content

[0005] The purpose of this invention is to provide a pharmaceutical packaging composite film to solve the problem mentioned in the background art that when the double aluminum film is broken open by pressing and the tablets inside are taken out, the opening is not guided, resulting in a lot of residue at the opening and affecting the appearance.

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0028] like Figures 1-3 As shown in the figure, the pharmaceutical packaging composite film provided by this utility model includes an outer film 1 and an aluminum film. The outer film 1 is provided with a printing layer, which is printed by ink using a thin film printing machine. It is mainly used to print the name of the tablet, manufacturer information, etc. The outer film 1 is made of polyethylene film. In a specific embodiment, the outer film 1 can be made of LDPE film. LDPE film is a low-density polyethylene film that is produced by polymerizing ethylene and then blowing it.

[0029] It should be noted that the outer film 1 and the aluminum film are pressed together using a hot press. The temperature during the hot press is 120–180℃ and the pressure is 0.5–1 MPa. After hot pressing, cooling and shaping are required.

[0030] To facilitate the identification of the tablet's location, an identification line 2 is provided on the outer film 1. The identification line 2 can be printed by a printing press, and its size is larger than that of the tablet storage area 14.

[0031] The composite film is provided with an easy-tear line 3 and a pressing protrusion 4. The easy-tear line 3 is arc-shaped and consists of multiple spaced separation holes that penetrate the aluminum film. The pressing protrusion 4 is located on one side of the easy-tear line 3. The pressing protrusion 4 then presses the aluminum film. The pressing protrusion 4 needs to be pressed after the first aluminum foil 6 is pressed with the outer film 1. Pressing the pressing protrusion 4 with a finger can cause the composite film to tear along the easy-tear line 3, thereby exposing the tablet storage area 14 in the composite film. In this way, the tablets between the composite film and the blister pack can be taken out, making it more convenient to remove the tablets.

[0032] It should be noted that the composite film has corner through holes 5 at its corners. When using it, you can hold the corner through holes 5 located on the side and then pull up the composite film to allow the composite film to be quickly separated from the blister pack.

[0033] In a specific embodiment, the aluminum film includes a first aluminum foil 6 and a second aluminum foil 7, which are attached one on top of the other. Specifically, the first aluminum foil 6 and the second aluminum foil 7 are pressed together by a hot press. An adhesive area is provided between the first aluminum foil 6 and the second aluminum foil 7, and PE adhesive is evenly applied to the adhesive area. The temperature of the hot press when pressing the first aluminum foil 6 and the second aluminum foil 7 is 130-180°C, and the pressure is 0.3-1.0 MPa.

[0034] For reference Figure 3 The aluminum film has a sterilization layer 8, a heat insulation layer 9, a separation layer 10, an inner film 11, and an adhesive coating area 12 arranged sequentially on its underside. The sterilization layer 8 can be made of PTFE film, the heat insulation layer 9 can be made of polyester film, the separation layer 10 can be made of silicon oxide film, and the inner film 11 can be made of polyethylene film. The adhesive coating area 12 is applied to the inner film 11 to bond the composite film to the blister pack. The adhesive used in the adhesive coating area 12 can be CT880 series adhesive. The upper end of the sterilization layer 8 is pressed and connected to the aluminum film using a hot press. The sterilization layer 8 and the heat insulation layer 9 are pressed together using a hot press. The heat insulation layer 9 is pressed onto the separation layer 10 using a hot press, and the separation layer 10 is pressed onto the inner film 11 using a hot press. The specific temperature and pressure can be adjusted according to the melting temperature and thickness of the films to be connected, and the combination order can be adjusted according to the melting temperature of the materials.

[0035] In a specific embodiment, a corner notch 13 is provided at the position of the corner through hole 5 corresponding to the glue application area 12. No glue is applied to the corner notch 13, so that the composite film is easier and more convenient to peel off.

[0036] For reference Figure 2 A tablet storage area 14 is provided at the composite membrane, and the end of the tablet storage area 14 coincides with the end of the heat insulation layer 9 away from the aluminum film. The tablet storage area 14 is used to store tablets.

[0037] In summary, this utility model provides a pharmaceutical packaging composite film with an easy-tear line 3 that penetrates the aluminum film but not the sterilization layer 8 or the heat insulation layer 9. Pressing the raised dots 4 and then the aluminum film causes the composite film to tear along the easy-tear line 3 under pressure, thus exposing the tablet storage area 14 within the composite film. This allows for easy removal of the tablets from the blister pack. Additionally, a corner notch 13 is provided at the bottom adhesive area 12 of the outer film 1, and corner through holes 5 are provided at the corners of the composite film. The composite film can be torn open from the corner notch 13 where no adhesive is applied, making separation easier. Furthermore, if misalignment is detected at the joint between the composite film and the blister pack before the adhesive dries, the composite film can be quickly torn off.

[0038] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
