The utility model relates to a degradable single-layer kraft paper packaging bag which can be used as an outer food packaging bag and a shell bag, has a good degradation effect, a good heat sealing effect and good waterproof performance, and belongs to the technical field of food packaging.
Background
CN 204998960U, name "a food package bag", including wrapping bag body and recycle bags, wrapping bag body shape is the narrow width down bag form, the wrapping bag body is two-layer inside and outside including, the inlayer is the polyethylene propylene film, the skin is the kraft paper, inlayer and skin become an organic whole through hot tectorial membrane, wrapping bag body bottom and edge are equipped with the crease, can inwards fold also outwards expand, the wrapping bag body back is equipped with a recycle bags. The packaging bag is characterized in that a pair of magnets are arranged below the opening of the packaging bag and arranged between the inner layer and the outer layer of the packaging bag body, the magnets are flaky, and the length of the magnets is equal to the width of the opening of the packaging bag. The wrapping bag back is located to the recycle bag, and the volume slightly is less than the wrapping bag body, the recycle bag is kraft paper material. The utility model discloses a wrapping bag, including recycle bag, recycle bag edge and wrapping bag body, recycle bag edge passes through the heat-seal with the wrapping bag body and is connected, the recycle bag opening is outside convex triangle-shaped, triangle-shaped apex angle department is equipped with a little magnet, little magnet attracts mutually with the magnet on the wrapping bag body. The environment-friendly bag is internally provided with toothpicks, paper and a small tray, the paper is arranged at the bottom of the small tray, the toothpicks are arranged on the paper, and the tray is placed towards the packaging bag body. The disadvantages are that: the food packaging bag can not be thoroughly degraded, and the production cost is higher.
SUMMERY OF THE UTILITY MODEL
The design purpose is as follows: for avoiding not enough among the background art, design one kind not only can use as food package outer bag, can use as the shell bag moreover, degradation effect is good simultaneously, and the effectual, the good degradable individual layer kraft paper wrapping bag of waterproof performance of heat-seal simultaneously.
The design scheme is as follows: the design purpose is realized.
1. One side of the kraft paper layer in the composite kraft paper is provided with a glue coating layer, and the quantitative weight of the glue coating layer is 5 g/square meter to 10 g/square meter, which is one of the technical characteristics of the utility model. The purpose of this design is: the composite kraft paper comprises a kraft paper layer and a gluing layer, so that the packaging bag made of the composite kraft paper can be used as an outer bag for food packaging and can also be used as a fruit shell bag, and the packaging bag has a degradable function; and the quantitative gluing layer has the weight of 5 g/square meter to 10 g/square meter, and has good heat sealing effect in the process of manufacturing a packaging bag and good waterproof effect after manufacturing the packaging bag.
2. The kraft paper layer has the design of quantitative 40 g/square meter to 80 g/square meter, which is the second technical characteristic of the utility model. The purpose of this design is: the quantitative kraft layer is 40 g/square meter-80 g/square meter, and the quantitative kraft layer ensures that the packaging bag has proper bearing capacity.
3. The packaging bag is characterized in that an easy-to-tear line is arranged at the upper port of the packaging bag body and is designed as a broken line. The purpose of this design is: the upper port department of wrapping bag body is equipped with easily tears the line, easily tear the line and be the break line, easily tear the setting of line and be convenient for the upper port of wrapping bag can be by the light tearing of being torn.
The technical scheme is as follows: the degradable single-layer kraft paper packaging bag comprises a packaging bag body, wherein the packaging bag body is made of composite kraft paper, a glue coating layer is arranged on one side face of a kraft paper layer in the composite kraft paper, and the quantitative weight of the glue coating layer is 5 g/square meter to 10 g/square meter.
Compared with the prior art, the degradable single-layer kraft paper packaging bag not only can be used as an outer food packaging bag, but also can be used as a fruit shell bag; and secondly, the degradable single-layer kraft paper packaging bag has good self-degradation effect, and also has good heat sealing effect and waterproof effect.
Drawings
Fig. 1 is a schematic sectional structure view of a composite kraft paper.
Fig. 2 is a schematic structural diagram of a degradable single-layer kraft paper packaging bag.
Detailed Description
Example 1: reference is made to figures 1-2 of the drawings. A degradable single-layer kraft paper packaging bag comprises a packaging bag body 1, wherein the packaging bag body 1 is made of composite kraft paper 2, a glue coating layer 22 is arranged on one side surface of a kraft paper layer 21 in the composite kraft paper 2, the quantitative amount of the glue coating layer 22 is 5 g/square meter to 10 g/square meter, and the quantitative glue coating layer 22 has a good heat sealing effect in a packaging bag manufacturing process and a good waterproof effect after the packaging bag is manufactured; when the quantitative amount of the coating layer 22 is less than 5g per square meter, the waterproof effect of the prepared package is poor, and when the quantitative amount of the coating layer 22 is more than 10g per square meter, the coating layer 22 cannot be completely heat-sealed in the process of preparing the packaging bag, namely the heat-sealing effect is poor. The kraft paper layer 21 has the quantitative content of 40 grams per square meter to 80 grams per square meter. Preferably, the kraft paper layer 21 has a basis weight of 60 grams per square meter.
