Detailed Description

The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the anti-tearing packaging bag in the embodiment includes an integrally formed packaging bag main body 100, the packaging bag main body 100 is square, the bottom end of the packaging bag main body 100 is heat sealed, a filling opening 110 is obliquely cut on one side of the top end of the packaging bag main body 100, the filling opening 110 includes an oblique cut section 111 and a horizontal cut section 112 which are sequentially connected, the size of the oblique cut section 111 is set according to a filling machine, the horizontal cut section 112 is parallel to the top end and the bottom end of the packaging bag main body 100 and is arranged near one side of the packaging bag main body 100, and a circular arc 113 at the connection part of the oblique cut section 111 and the horizontal cut section 112 is in transition.

In the prior art, a sharp corner is formed after the filling opening 110 which is directly obliquely cut is unfolded, the tearing is very easy to cause in the unfolding process, the anti-tearing packaging bag is simple in structure, and the filling opening is in a special shape structure, so that the conditions of tearing and the like in the using process are effectively prevented.

Preferably, the top end of the pack body 100 is heat-sealed.

Among this technical scheme, after the material filling, for avoiding in the transportation material to reveal, the wrapping bag needs sealed, before the filling, the top heat-seal, only need the heat-seal filling mouth after the filling can, reduced the length of heat-seal after the filling, improved the speed of encapsulation and the quality of encapsulation, relative cost is greatly reduced also.

Preferably, V-shaped flanges 120 are respectively formed at both sides of the pack body 100.

In the technical scheme, the V-shaped folding edges are arranged on the two sides of the packaging bag main body, so that the packaging bag main body does not occupy too large space when not used after being folded, and the V-shaped folding edges can expand the inner space of the packaging bag main body to a great extent in a use state so as to accommodate more objects to be packaged; moreover, the V-shaped folded edge is convenient for workers to grasp in the transportation process, and the packaging bag cannot be easily torn.

Preferably, the length of the horizontal cut segment 112 is not less than 5 cm.

Preferably, the radius of the circular arc 113 is 5 cm.

Among the two above-mentioned technical scheme, the setting of horizontal dissection and circular arc for there is not the closed angle after the filling mouth expandes, thereby avoids the tearing condition to appear in the use.

In summary, the anti-tearing packaging bag has a simple structure, and the filling opening adopts a special shape structure, so that the conditions of tearing and the like in the use process are effectively prevented; meanwhile, the two side faces of the packaging bag body are provided with the V-shaped folding edges, so that the capacity of the packaging bag can be further expanded, and more packaged objects can be accommodated on the premise that the strength of the packaging bag is high enough, so that the use and transportation cost is reduced.
