Abstract

The utility model discloses a packaging bag. The front surface and the bottom of a bag body are rectangular. Inverted-Y-shaped fold lines are arranged on the two sides of the bag body. The bottom of the bag body is formed by bonding a front folding surface, a rear folding surface, a left folding surface and a right folding surface along the adjacent sides. According to the packaging bag, the steadiness and the bearing capacity of the bottom surface can be improved so that the packaging bag can stand on a plane stably, the front surface, the rear surface and the two side surfaces are fully utilized, and the raw materials can be saved by more than 10 percent.

Description

A kind of packaging bag

Technical field

The utility model relates to the packing technique field, the packaging bag that particularly can support oneself and fold.

Background technology

Packaging bag is of a great variety, and a kind of self-support and folding wrapping bag are wherein arranged, under the bag-shaped state of sky, can take in be folded into laminar, to save space, under dress thing state, content struts bag, its bottom is a supporting plane, can be upright voluntarily, so that put.

Existing self-support and folding wrapping bag design comparison are single, and material consumption is larger, and astasia.

The utility model content

The purpose of this utility model is to provide a kind of packaging bag.This bag material consumption is little, and it is stable to stand.

To achieve these goals, the utility model provides a kind of packaging bag, and its bag front and bottom are rectangle, and both sides are provided with down " Y " shape folding line, and described bag bottom is formed along adjacent edge is bonding by front fold plane, rear fold plane, left folding face and right folding face.

Preferably, described front fold plane and rear fold plane are trapezoidal, and be symmetrical along the cross central line front and back of bag bottom.

Preferably, the bonding region of described front fold plane and rear fold plane is folding to a side along its base.

Preferably, described left folding face is trapezoidal with right folding face, along the longitudinal centerline left-right symmetric of bag bottom.

Preferably, described left folding face is inwardly folding in mode in opposite directions along its base with the bonding region of right folding face.

Preferably, described bag front is provided with together laterally fold cross, and this fold cross is alignd with the described tapping point of " Y " shape folding line.

Preferably, described bag is formed by one whole plastics or paper folding and spicing.

Preferably, the adhesion width scope of described adjacent edge is between 5mm-10mm.

The utility model has been done further improvement on the basis of existing technology, its bag front and bottom are rectangle, both sides are provided with down " Y " shape folding line, and described bag bottom is formed along adjacent edge is bonding by front fold plane, rear fold plane, left folding face and right folding face.It can improve smoothness and the weight capacity of bottom surface on the one hand, can steadily stand in the plane, takes full advantage of on the other hand each front, the back side and two sides, can save material more than 10%.

The specific embodiment

In order to make those skilled in the art person understand better the utility model scheme, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As shown in the figure, in a kind of specific embodiment, the packaging bag that the utility model provides is formed by one whole plastics or paper folding and spicing, front 11 and the bottom 12 of its bag 1 are rectangle, both sides are provided with down " Y " shape folding line 13, and bag bottom 12 is formed along adjacent edge is bonding by front fold plane 12-1, rear fold plane 12-2, left folding face 12-3 and right folding face 12-4.

Front fold plane 12-1 and rear fold plane 12-2 are trapezoidal substantially, and symmetrical along the cross central line front and back of bag bottom 12, both bonding regions are folding along its base (shown in dotted line) to a side.

Left folding face 12-3 and right folding face 12-4 are trapezoidal substantially, and along the longitudinal centerline left-right symmetric of bag bottom 12, both bonding regions are inwardly folding in mode in opposite directions along its base (shown in dotted line).

The adhesion width of above-mentioned adjacent edge can be controlled between 5mm-10mm.

The bag front is provided with together laterally fold cross 14, this fold cross with fall the tapping point of " Y " shape folding line 13 and align, under the bag-shaped state of sky, after bag bottom 12 is folding along horizontal fold cross 14 and a bag body fit and be laminar.

This packaging bag can improve smoothness and the weight capacity of bottom surface on the one hand, can steadily stand in the plane, takes full advantage of on the other hand each front, the back side and two sides, can save material more than 10%.

Above packaging bag provided by the utility model is described in detail.Applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand core concept of the present utility model.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
