The present invention relates to a partly peelable packaging pouch that can be easily opened by pulling only the portion to be opened, and in particular, to improve the opening of the pouch to provide convenience to consumers, and The present invention relates to a packaging pouch that can be easily peeled off only on a necessary part (hereinafter referred to as “easy peel film”) while inserting a sealing film and producing it by sealing, thereby reducing production costs and making it easy to use.

A pouch, which is usually a packaging container, seals the three sides of the front and rear films to form an envelope, seals the upper part after receiving the product therein, and notches or uses scissors on one side of the upper part. To cut it.

In the case of the notched pouch, the thicker the film is, the more the consumer is forced to open by cutting, and the unsealable opening occurs. In addition, the pouch is irregularly cut and caught on the contents by opening. In some cases, it is difficult to open the product. On the other hand, when the product containing moisture is excessively opened, or when the cutting surface is irregular, there is an inconvenience of splashing water and burying it in the consumer. There was also the hassle of having to throw it out twice, once after the product was consumed.

In addition, when a zipper is installed, the zipper may be damaged or fall off when the opening part is cut, and there is a problem in that opening is insufficient due to a lack of catching part when opening the zipper.

Packaging pouches using Easy Peel Film have been provided to alleviate the inconveniences described above. These pouches maintain convenient thermal adhesive strength that can be opened by hand and are convenient with the protection of packaged products. It is possible to satisfy the opening property at the same time.

The principle of the Easy Peel is to control the heat adhesion strength by mixing a special resin to be easily opened, for this purpose is to control the heat adhesion strength by micro-dispersing the incompatible resin in the compatible resin.

The peeling form of the easy peel film is an interlayer peeling type (Delami Type), cohesive fracture type (Cohesive Type), interfacial peeling type (Interfacial Type).

The interlayer peeling type is to be opened while the surface layer of the film is peeled off, and the type to control the thermal adhesive strength by adjusting the strength of the interlayer bonding strength of the center layer and the surface layer, the aggregation breaking type is opened while a portion of the surface layer is broken. When opened, the residue remains in the container and is not clean, which may give me only the image of the product. Currently, products with high refill strength are preferred for retort sterilization, which is why interlaminar peeling and cohesive failure are mainly used.

The interfacial peel type is peeled off at the interface between the film and the container, and since the residue is not left in the container, the cleanest separation results in the advantage of not damaging the product image to the consumers. It has a disadvantage of weak adhesive strength and is not suitable for a product requiring high easy peel strength.

The above easy peel film is a dessert food (jelly, prim, yogurt, jam, etc.), aquatic foods (tofu, tea, seaweed, etc.), confectionery (chocolate, frozen dessert, sandwich, water yolk, etc.), other foods (miban, dairy products ( Butter, margarine, cup noodles, etc.), non-food items (toner, carrier tape, medical sap, etc.) can be variously applied.

Conventional packaging pouch applying the easy peel film as described above can be easily opened regardless of the film thickness when opening, preventing the leakage of moisture due to irregular cutting surface, there is an advantage that only once discarded after product consumption, but easy to fill the whole surface By inserting the film, there is a disadvantage in that the production cost is high, the heat adhesive strength is weak, the problem that is caused by the impact load during the packaging of the product weighed out, such as a problem occurred.

The present invention is to improve the above problems, the object of the present invention is to easily open by pulling only the portion to be opened, first, to provide convenience to consumers by improving the opening of the pouch, and second By inserting the easy-fill film into only the parts necessary for opening, it is possible to provide a packaging pouch that can be easily peeled off to reduce the production cost.
