One or a plurality of them are arranged in parallel in the plastic film 1. [Selection] Figure 2

Description

  This proposal relates to a single-shaped tearing composite membrane.

  Conventionally, many packaging in the market adopts plastic film, which is clean and convenient to use. The most new function is the PE ziplock bag, which becomes a straight line after tearing the package, and the inner seal in the package can be opened and closed repeatedly. In this way, it is airtight and guarantees food safety and cleanliness. However, if the configuration loses the inner seal, the plastic film cannot be torn into a single straight line

  Compared to products such as PE ziplock bags or traditional “one-shaped tear” membranes, it does not require increased functional assembly, while at the same time it seals well and is united together, traditional products require assembly Overcoming the problems that are or are not sealable.

  The purpose of this proposal is to provide a one-shaped tearing composite membrane, the plastic film itself has the effect of being able to tear in one straight line, and by tearing the packaging of this composite plastic film, it is always one complete straight line .

  In order to achieve the above object, the present plan provides the following technical solutions. The one-shaped tearing composite membrane has a structure in which notches or holes in the plastic film a are sharp at one end and wide at the other end, that is, in the form of “<”, “>” that are continuously arranged in the plastic film a. The plastic film b is a complete plastic film, and is combined with the plastic film a to form a single composite film. The notches or holes in a are arranged in a straight line and have a constant spacing, and the arrangement method is that the sharp end is directed to the wide end.

  Further, when the plastic film a is used for one package, one or a plurality of parallel cutout bars having a “V” shape in the horizontal direction or a hole bar having a triangular shape and a bullet shape in the horizontal direction. Have

  Furthermore, one notch is provided on the outer edge, which is used to guide the tearing of the composite membrane.

  Furthermore, when used in packaging, one or more parallel cutout bars or hole bars coincide with the tear direction with the cutouts at the outer edges.

  Further, the outer edge notches are directed to the wide ends of the “<” and “>” shaped notches, triangular holes, and bullets in the lateral direction.

  Furthermore, the “<” and “>” cutouts are arranged so as to form one straight line continuously arranged in the horizontal direction “>>>>” from left to right.

  Furthermore, the one-shaped tearing composite film may be used in combination with other single or composite plastic films, or may be used alone as a packaging film.

  Furthermore, the plastic film a can be used as a plastic film with a guiding function.

  Furthermore, the plastic film b is a single plastic film or a composite packaging film with functionality, for example, an aluminum vapor deposition film.

  Further, the plastic film a and the plastic film b are usually bonded as a composite film by an adhesive.

  Further, after one surface of the plastic film a is bonded to the plastic film b, an effect is achieved in which a coating film is further applied to the other surface of the plastic film a and completely wrapped.

  Further, usually, plastic films need to be color-printed, but it is necessary to perform process operations such as multi-layer composite or vacuum aluminum plating as food packaging.

  Furthermore, in the industry, plastic films have a production method of rolling and an extrusion method, and the extrusion method is divided into an extruded inflation film.

  Furthermore, rolling methods such as extrusion casting and extrusion tension (also referred to as secondary forming) are mainly used for the production of polyvinyl chloride films.

  Further, common plastic films include polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), polyester film (PET), polypropylene (PP), nylon and the like.

    A good effect of this proposal is that the one-shaped tearing composite film has an effect of maintaining a single straight line when it is torn by improving the structure. By performing a composite treatment on the membrane, the plastic film has good sealing properties, and since there are holes, the sealing properties of the membrane are not reduced. The letter-shaped tearing composite membrane can be used in conjunction with the composite membrane in the package as a functioning auxiliary membrane, or it can be used as an independent plastic film packaging. It is low in production cost, easy to process and has good sealing properties.

  Hereinafter, the present plan will be described in more detail with reference to the drawings and specific embodiments.

  As shown in FIGS. 1-6, the 1-shaped tearing composite film includes a plastic film a1 and a plastic film b2, and the plastic film a1 and the plastic film b2 form one composite film 3 by adhesion. The plastic film a1 has “<” and “>” cutouts 11, triangular holes 12, bullet holes 13 in the lateral direction, and a sharp end 14 arranged sequentially toward a wide end 15. In the middle, there is an interval 16. One or a plurality of them are arranged in parallel in the plastic film 1.

  When the composite film 3 is used as an auxiliary film with a function, it synthesizes another film 4 and a new composite multi-functional composite film 5, for example, the composite film 3 and the aluminum vapor-deposited film are combined again, and the functionality The composite aluminum deposition film, that is, the multifunctional composite film 5 is formed.

  When the composite membrane 3 wraps one packaging bag 6, an outer edge notch 61 is provided at the opening position of the packaging bag 6. The outer edge notch 61 is directed toward the wide side 15 of the “<”, “>” shaped notch 11, the triangular hole 12 or the hole 13 having a bullet shape in the lateral direction, and the tearing direction thereof is Is a match. The outer edge notch 61 is located at the top position of the packaging bag, and usually only one notch is located on the left or right side.
