Description

[Detailed Description of the Invention] The present invention relates to a paper carrying bag equipped with a handle that can be easily and securely attached to a paper bag, has strength and water resistance, and has appropriate flexibility.

Conventional paper carrier bags have a handle made of paper or synthetic resin attached to them.

Paper handles are easy to attach to paper bags and feel good when in use, but they lose strength and break when sweat soaks in.

In addition, although synthetic resin handles are strong, they are difficult to attach to paper bags, require welding equipment, and are expensive, and have the disadvantage that they do not feel good when in use. be.

Therefore, the inventor proposed a paper carrying bag equipped with a handle that is easy to attach to a paper bag, has a good feel during use, and has excellent strength.

Examples will be explained below.

Figure 2 is a cross-sectional view of the material of the handle, which has a constant width and is shaped like a belt. 1 is a strong paper like kraft paper;
Reference numeral 2 is a sheet-like synthetic resin material laminated on the upper surface of polyethylene, polyester, nylon, polypropylene, etc., which can be stretched and has relatively high strength.

In Figures 3 and 4, each side of the material is folded so that the resin part is on the inside and the paper is exposed on both sides on the outside. A cross-sectional view of the state shown in FIG.

In the case of folding in four, the final folded surface is glued 5 with adhesive.

The carrying bag according to the present invention is made by cutting this material to an appropriate length and bending it to form a handle A, and then wrapping the both ends of the material between two pieces of padding paper 4, 4 using a general material such as starch glue or latex. Apply the adhesive and hold it in place, and then apply the backing paper 4.
, 4 are attached to the inner surface of the opening of the bag body B.

Since the present invention is constructed as described above, the handle is not only easily and securely attached to the backing paper, but also has a synthetic resin sheet inside the handle A in the form of a core. Therefore, it is strong, flexible and feels good to the touch when in use, and there is no risk of the handle breaking due to sweat or slight moisture.

In addition, because of the above configuration, a general paper adhesive can be used to attach the handle to the backing paper, and there is no need for welding. Since the production efficiency can be increased by using the same equipment as before, the work process can be shortened and manufacturing can be carried out at low cost.

Furthermore, since the paper is always exposed on the outer surface, desired printing can be applied to the surface of the handle.

Claims (1)

[Scope of utility model registration request] A material in which a synthetic resin sheet 2 is laminated on the upper surface of a paper 1 having strength similar to kraft paper is bent and welded on both sides with the synthetic resin sheet portion inside, and then cut to a required length to form a handle A. This paper carrying bag is characterized in that both ends of the handle A are stuck between two sheets of padding paper 4, 4 with an adhesive, and the padding paper 4 is stuck and fixed to the opening of the bag body B.
