Background technique

Nowadays, disposable packaging bags are widely used in the packaging of various granular, powdery, liquid and other commodities, especially bagged food is inseparable from disposable packaging tapes. The extensive use of disposable packaging bags not only facilitates our lives, but also brings environmental pollution problems that cannot be ignored. A large number of packaging bags are made of plastic, and a gap must be torn before use. Many packaging bags When tearing, the torn part is broken from the bag body. If the items in the bag cannot be used up at one time, the user should seal the tear opening on the packaging bag with clips or adhesive tape to prevent the items in the bag from leaking or being damp. , all of which increase the trouble for users to deal with. After the items in the bag are used up, the recycling of the packaging bag becomes a problem. The packaging bag is generally very light and thin. If people do not carefully deliver the packaging bags to the trash can, the packaging bags will easily fall out of the trash can, and many people are used to throwing away the used packaging bags at will. The packaging bags that fall to the ground are easily blown away by the wind, and the cost of recycling become an important factor of environmental pollution. To solve this problem, packaging bags that are convenient to use and easy to recycle must be designed.

Contents of the invention

The purpose of the present invention is to provide a kind of easy-tear environmental protection packing bag that is convenient to recycle, and this packing bag comprises a bag body 1, and there is a tearing crease 3 near the pre-opening end 2 of bag body 1, and this tearing crease 3 There is a tear gap 5 at one end 4 of the tear crease 5, which is located on one side 6 of the bag body 1, and the other end 7 of the tear crease 3 has a crack relief gap 8, which is not connected with the bag body 1. any edge connected. When tearing the pre-opening end 2 like this, it does not break from the bag body 1 .

There is an anti-crack reinforcing ring 9 on the above-mentioned anti-crack gap 8, which is a section of hard ring material, which is inlaid on the anti-crack gap 8. When the pre-opening end 2 of the bag body 1 is cut along the tear crease 3 When tearing apart, the crack reaches the crack relief gap 8 and meets the reinforcement ring 9, the crack no longer extends, and the pre-opening end 2 will not break, and remains connected to the bag body 1.

A further improvement to the above technical solution is that: a flexible thread 15 is embedded in the tearing crease 3 , and the two ends of the flexible thread 15 are respectively connected with the tearing notch 5 and the cracking notch 8 . The effect of the flexible silk thread 15 here is to facilitate the user to tear the pre-opening end 2 of the bag body 1 along a straight line. The strength and toughness of the flexible silk thread 15 are higher than that of the bag body 1 material, but the elasticity is low and it is not easy to elongate. The bag body 1 material is cut open with very little power, and the cut is also smooth and linear. The flexible wire 15 can be made of non-rusting metal material, such as aluminum wire or hard fiber wire. The flexible silk thread 15 can also play the role of the recycling packaging bag of the aforementioned strip elastic clip 11 here, that is, the user kneads the used packaging bag into a small ball, which can be wrapped with the flexible silk thread 15 to prevent it from falling apart.

In the above solution, the tear crease 3 , the tear notch 5 , and the flexible thread 15 are all located on the edge line of the pre-opening end 2 . In this way, one edge of the bag body 1 can be used as a tear opening, and the maximum volume of the packaging bag can be kept constant after being torn, and keep its original shape, which is convenient for repeated use.

A further improvement to the above technical solution lies in that the tearing crease 3 , the tearing notch 5 , and the cracking notch 8 are only located on one of the planes of the bag body 1 . When the pre-opening end 2 of the bag body 1 is torn like this, it is only torn from one side, keeping the integrity of the other side.

The easy-to-tear environment-friendly packaging bag provided by the invention can bring the following beneficial effects:

This easy-to-tear environmentally friendly packaging bag can solve two common problems of various small packaging bags at present. One is that the opening of the packaging bag is not easy to tear, and the other is that the torn opening part and the used packaging bag are not easy to recycle, causing environmental pollution. .
