Abstract

A paper packaging bag with a paper-plastic separation structure, comprising: a paper outer layer bag, the mouth of the paper outer layer bag is provided with a flap for sealing the mouth of the bag, and the inner wall of the paper outer layer bag is lined with The flexible cushioning layer is characterized in that: the periphery of the flexible cushioning layer is adhered to the inner wall of the paper outer layer bag. Compared with the prior art, the utility model has the beneficial effects that the paper packaging bag with the paper-plastic separation structure has a scientific design and a simple and reasonable structure. The peripheral adhesion between the flexible cushioning layer and the paper outer bag makes it easier to peel off the paper and plastic during the recycling process of such waste packaging bags, which greatly facilitates the recycling of packaging bags and is conducive to environmental protection .

Description

Paper packaging bag with paper-plastic separation structure

technical field

The utility model relates to the improvement of the packaging bag structure, in particular to a paper packaging bag with a paper-plastic separation structure.

Background technique

At present, in order to prevent items from being damaged due to road bumps or handling bumps during transportation, paper packaging bags compounded with plastic buffer bubble films are usually used for packaging. This kind of paper packaging bag with cushioning air bubble film can avoid the damage of packaged items caused by bumps and bumps during transportation. This kind of packaging bag has become the most widely used item packaging method in the logistics industry. Existing paper packaging bags compounded with plastic buffer bubble film usually consist of a paper outer layer that is convenient for writing, a PE film layer compounded on the inner wall of the outer paper layer, and a PE film layer that is hot-melt pasted on the inner wall of the outer paper layer. Made of PE bubble film layer, its structure is very strong and durable. However, when recycling waste paper air bubble film composite packaging bags, since the PE air bubble film layer is completely thermally melted and compounded on the PE film layer on the inner wall of the paper outer layer bag, the PE air bubbles firmly adhered to the inner wall of the paper outer layer bag The film layer is difficult to peel off. Therefore, it is difficult to recycle the paper outer layer part of the packaging bag. Recycling of such packaging bags increases the cost of recycling.

Utility model content

The technical problem to be solved by the utility model is to make up for the shortcomings of the above-mentioned background technology, and propose a paper packaging bag with a paper-plastic separation structure that can be easily separated from the buffer bubble film and the paper bag part, and is convenient for recycling.

The technical problems of the utility model are solved by the following technical solutions.

This paper packaging bag with a paper-plastic separation structure includes: a paper outer bag, the mouth of the paper outer bag is provided with a flap for sealing the mouth of the bag, and the inner wall of the paper outer bag is lined with a flexible quality buffer layer.

The characteristics of this paper packaging bag with paper-plastic separation structure are:

The periphery of the flexible cushioning layer is adhered to the inner wall of the paper outer layer bag.

The technical problems of the present invention are solved by the following further technical solutions.

The flexible buffer layer is a PE bubble film layer.

The periphery of the soft cushioning layer and the inner wall of the paper outer bag are bonded by hot melt or glue.

A self-adhesive layer is provided on the pocket flap of the paper outer bag.

The design principle of the utility model is: on the basis of not changing the original function of the paper packaging bag with a soft protective layer, the flexible buffer layer that was originally completely compounded and pasted on the inner wall of the paper outer layer bag changes the peripheral adhesion and reduces the softness. The adhesive position between the buffer layer and the inner wall of the paper outer layer bag provides convenience for the flexible buffer layer to be peeled off from the inner wall of the paper outer layer bag.

Compared with the prior art, the utility model has the following beneficial effects:

The paper packaging bag with paper-plastic separation structure has scientific design, simple and reasonable structure. The peripheral adhesion between the soft buffer layer and the inner wall of the paper outer bag can overcome the defect that the soft buffer layer is difficult to peel off from the inner wall of the paper outer bag during the waste recycling process of existing similar products. The paper packaging bag with paper-plastic separation structure of the utility model has the characteristics of easy stripping of the soft buffer layer paper, greatly facilitates the recycling and reuse of the packaging bag, and is beneficial to environmental protection.

The specific structure of the paper packaging bag with paper-plastic separation structure of the utility model is given in detail by the following drawings and examples.

Description of drawings

Figure 1 is a schematic diagram of the structure of a paper packaging bag with a paper-plastic separation structure.

Detailed ways

It can be seen from Figure 1 that the basic structural shape of the paper packaging bag with a paper-plastic separation structure is the same as that of the existing paper packaging bag with a soft protective layer, and the paper packaging bag with a paper-plastic separation structure consists of a paper outer bag 1 and the PE bubble film layer 2 lined on its inner wall. The mouth of the paper outer layer bag 1 is provided with a flap 3 for sealing the mouth of the bag. The periphery of the PE bubble film layer 2 is hot-melt bonded 4 to the inner wall of the paper outer layer bag 1 . A self-adhesive layer 5 is provided at the flap 3 at the mouth of the paper outer bag 1 .

The above content is a detailed description of the utility model in conjunction with a specific preferred embodiment, and it cannot be determined that the structural design of the utility model is only limited to these descriptions. For engineers and technicians in this technical field, without departing from the concept of the utility model, some changes and improvements can also be made, which should be regarded as belonging to the patent protection of the utility model determined by the submitted claims scope.
