Technical Field

The utility model belongs to the technical field of the packing, concretely relates to paper wrapping bag of built-in compartment.

Background

Some food packages exist in the market at present, a plurality of small packaging bags are arranged in an outer large packaging bag, the outer large packaging bag is mostly of a PET/PE or paper/PE structure, no barrier performance requirement exists, no effect on the quality guarantee period is required, and the food packaging bag belongs to simple packaging. However, with the development of the times, the reduction of the use of plastics is a new trend, so that the improvement of the material of the outer package is required, and the material is more consistent with the time theme of environmental protection.

Disclosure of Invention

The utility model discloses mainly to the above-mentioned problem that the packaging film exists, invented a paper wrapping bag of built-in compartment, it is convenient for the box to deposit built-in little wrapping bag to compare with plastics more environmental protection.

The above technical problem of the present invention can be solved by the following technical solutions: a paper packaging bag with a built-in compartment comprises a paper packaging film and a packaging bag made of the paper packaging film, wherein the paper packaging film comprises a paper layer, a waterproof layer is arranged on the inner side of the paper layer, and a positioning heat-sealing area is arranged on the inner side of the waterproof layer; the middle of wrapping bag becomes first space and second space through folding baffle with inside partition, and folding baffle includes two locating plates of fixed connection at wrapping bag both sides inner wall and connects the folded sheet of two locating plates, and the top side in first space and second space is equipped with easily tears the mouth, and easily tears mouth department and be connected with easily tearing the line, and the top of wrapping bag is equipped with the opening. The arrangement adopts paper to replace plastic as a printing gluing base material, so that the printing gluing base material is more environment-friendly; cut apart inner space through setting up folding baffle, can be used for placing little packing or different products, the folding setting of baffle can increase inside parking space.

Preferably, the paper weight of the paper layer is more than 120 grams per square meter, and the smoothness of two sides of the paper is more than 1200. The paper gram weight requirement can guarantee the stiffness and the hand feeling of the finished packaging bag, and the smoothness requirement can guarantee the printing appearance and the gluing uniformity.

Preferably, the waterproof layer is a water-based barrier coating which is coated on the paper layer in a full-page manner and is used for isolating water vapor.

Preferably, the positioning heat-sealing area is coated with a low-temperature heat-sealing coating, and comprises four side edges of the packaging bag and a connecting part between the middle of the packaging bag and the positioning plate.

Preferably, the folding baffle comprises a paper layer, and waterproof layers are arranged on two sides of the paper layer.

Preferably, the tear line is curved and extends from the tear opening to a position at the top of the first/second space adjacent the folding flap. The easy-to-tear line can be torn more conveniently, and can effectively control the tearing curve, avoid too big, undersize or destroy the closure of the other side space.

To sum up, compared with the prior art, the utility model has the following advantages:

1. the utility model adopts paper to replace plastic as printing and gluing base material, which is more environment-friendly, requires the paper gram weight to be more than 120 g/square meter to ensure the stiffness and hand feeling of the finished product packaging bag, and requires the smoothness of the two sides of the paper to be more than 1200 to ensure the printing appearance and the gluing uniformity;

2. the utility model discloses a set up folding baffle and cut apart into two spaces with the wrapping bag, can be used for placing little packing or the product of different varieties, folding baffle has effectively enlarged the inner space, and the line of easily tearing can more conveniently tear to can effective control tear the curve, avoid too big, the undersize or destroy the closure in opposite side space.
