Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that all the directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.
In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
In embodiment 1 of the present invention, referring to fig. 1, fig. 2, and fig. 3, a layered structure for a package jacket is provided, including a PET layer 2 and a PETG layer 6, and an anti-counterfeiting layer is disposed between the PET layer 2 and the PETG layer 6, which can prevent the anti-counterfeiting layer from being damaged by human or external friction, and thus, the stability of the anti-counterfeiting structure is not affected.
In embodiment 1 of the utility model, the anti-counterfeiting layer comprises a laser anti-counterfeiting layer 7 and a picture and text anti-counterfeiting layer 3, and the two anti-counterfeiting structures have good anti-counterfeiting effect and appearance effect.
In other embodiments of the present invention, the anti-counterfeiting layer is only one of the laser anti-counterfeiting layer 7 or the image-text anti-counterfeiting layer 3, and the anti-counterfeiting layer mainly plays a role in anti-counterfeiting.
In order to increase the grade of the layered structure and to be used as a symbol of identity, a gold stamping layer 4 is further included, the gold stamping layer 4 is arranged on the outer surface of any one of the PET layer 2 and the PETG layer 6 and/or between the PET layer 2 and the PETG layer 6, and in order to further protect the gold stamping layer 4, the gold stamping layer 4 is arranged between the PET layer 2 and the PETG layer 6 in embodiment 1 of the present invention.
