The specific embodiments are described in detail below to explain the present invention in detail, and the drawings are used as a supplementary description. The symbols mentioned in the description are referenced to the schematic symbols. It is worth noting that the "include" mentioned in the description is an open term and should be interpreted as "including, but not limited to". In addition, those of ordinary skill in the art should understand that the same component/product often has a different calling party. For example, "inner film" or "inner film tape", it is a matter of course that the components/products of the same kind and functionally similar to those mentioned in the specification are included in the scope of the present specification.

The specific embodiments of the present invention are described below with reference to the drawings; it is to be understood that the elements indicated in the drawings are for clarity and do not represent actual dimensions and proportions, and In order to facilitate understanding, the drawing of conventional components is also omitted in some drawings.

Please refer to the first drawing, which is a top plan view of a specific embodiment before cutting the processed food packaging material of the present invention.

The packaging material 1 for processing food before cutting in the first figure is a long strip shape, and the packaging material for processed food before cutting 1 can be used for automatic packaging machine to automatically process processed food, and the automatic packaging machine can be cut according to the size of processed food. Packaging material for processed food before cutting 1 .

In the specific embodiment of the present invention, the packaged food material 1 for cutting processed food comprises the easy tear strip 5, the inner film strip 6, the inner film strip 7 and the outer film 10. The width of the outer film 10 can be adjusted according to the size of the processed food, and the length of the outer film 10 is adjusted according to the amount of processed food that can be packaged by the processed food packaging material 1 before cutting. The tear strip 5 is joined to one surface of the outer film 10 and extends from one end to the other end in the longitudinal direction of the outer film 10. The inner film strips 6, 7 are joined to one surface of the outer film 10 and extend from one end of the outer film 10 to the other end in the direction of the parallel tear strip 5.

In an embodiment of the invention, the tear strip 5 and the inner film strip 6 and the inner film strip 7 are partially or completely bonded to the same surface of the outer film 10 by heat bonding. The inner film strip 6 and the inner film strip 7 have the same length as the outer film 10, and the inner film strip 6 and the inner film strip 7 have a width smaller than the width of the outer film 10. The length of the tear strip 5 is the same as the length of the inner film strip 6 and the inner film strip 7, and in one embodiment of the invention, the width of the tear strip 5 is smaller than the width of the inner film strip 6 and the inner film strip 7 degree.

In this embodiment, the preferred embodiment of the tear strip 5 is that the outer film 10 is centered to the right or to the left. According to the arrangement, the food can be processed after the consumer uses the easy tear strip 5 to disassemble the packaging material. The outer surface of the packaging material is exposed to prevent the easy-to-tear strip 5 from being disposed in the middle to cause the exposed portion of the processed food to be easily dropped.

In this embodiment, the inner film strip 6 and the inner film strip 7 are preferably disposed at the left and right sides of the tear strip 5 respectively, thereby making the packaged food product 1 having a substantially uniform thickness before cutting. The packaging material 1 for pre-cut processed foods can be uniformly wound, which is convenient for storage and transportation by winding, and can also be used for processing processed foods in the automated production line for packaging processed food packaging materials 1 before cutting. The packaging material 1 can be smoothly wound into the machine. Further preferably, the inner film strips 6, 7 and the tear strip 5 are located on the same surface of the outer film 10. It will be readily understood by those skilled in the art that the present invention may also employ embodiments in which the inner film 6, 7 and the tear-off strip 5 are on different surfaces of the outer film 10, provided that the thickness of the packaging material 1 of the present invention is substantially uniform.

In this embodiment of the invention, the tear strip 5, the inner film strip 6, the inner film strip 7 and the outer film 10 may be formed by using a general-purpose film having thermal properties; wherein the general-purpose film may be polyethylene, A synthetic resin film such as polypropylene.

Please also refer to the second drawing, which is a schematic view of a specific embodiment of the wound state of the processed food packaging material of the present invention.

The second figure shows that the packaging material 1 for processed food before cutting is presented in a wound state, and the inner film strip 6 and the inner film strip 7 can be used to make the packaged food packaging material 1 in the wound state. It is roughly uniform. It can be seen from the second figure that if only the easy-to-tear strip on the packaging material causes the thickness of the columnar intermediate to increase when the packaging material is wound, the thickness of the packaging material in the wound state is not uniform, and the packaging material is loose and cannot be column-shaped, and the packaging is Material cannot be stored and transported by winding At the same time, when using the machine to package processed foods in packaging materials, the thickness of the packaging materials may be uneven due to the easy tearing strips on the packaging materials, so that the machine cannot properly wrap the packaging materials into them.

Referring to the third and fourth figures, the third drawing shows a schematic view of a specific embodiment of the structure of the processed food packaging material of the present invention, and the fourth drawing is a sectional view of the third drawing.

The present invention is passed through an automated packaging machine. The outer film 10 is perpendicular to the first film except that the film 10 is bonded to the sides of the easy tear strip 5 in a manner that the tear strip 5, the inner film strip 6 and the inner film strip 7 are inwardly joined to each other. The upper and lower sides of the easy-to-tear strip 5 are respectively joined to each other, and then cut to a size of the processed food. The packaged food material 1 before cutting is a packaging film 21 for processing food, and a receiving space 30 is formed in the middle of the packaging film 21 for processed food. The processed food can be placed in the accommodating space 30. The packaging film body 20 can be cut into a straight line or a zigzag shape perpendicular to the upper and lower sides of the easy-to-tear strip 5. If the line is cut, at least all the mouths need to be cut at the side of the packaging film body 20 and located on the side of the tear strip 25. The order in which the processed foods are placed in the receiving space 30 can be changed in accordance with an automated packaging process.

In this embodiment, the packaging film body 20 is used to package processed foods and to print a printed graphic 28, which may include product names, product contents, product schematics, and the like. The easy tear strip 25, the inner film strip 26 and the inner film strip 27 are joined to the inner surface of the packaging film body 20 inside the processed food packaging film 21. The tear film mark 29 can also be printed on the packaging film 21 for processed foods for the convenience of the consumer to take apart the packaging film 21 for the processed food using the easy tear strip 25.

By using the packaging material for processed food of the present invention, the packaging material can be conveniently stored and transported by winding, and when the processed food is packaged in a packaging material on an automated production line, the packaging material can be smoothly wound into the machine because of the uniform thickness. The machine automation packaging process is smooth, and the machine replaces the manpower, increasing the packaging material production capacity and promoting the industrial development.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included within the scope of the appended claims.
