Description

Technical Field

[0001] This utility model belongs to the field of food packaging technology, and more specifically relates to a food preservation bag. Background Technology

[0002] Most plastic film food storage bags are currently rolled up on a paper tube, with each bag connected by a dotted tear line, also known as an easy-tear line. After tearing off a bag, you open the opening and put in the food to be stored. To reduce the contact between the food and air, a knot is usually tied at the opening. However, because the opening is flat, the knot is very easy to loosen. Alternatively, you can gather the opening into a bundle and tie a knot, but this is difficult to untie. Or you can use a rope to tie the opening tightly, which is also difficult. Therefore, most users simply leave the bag open, resulting in poor food preservation. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a food preservation bag that can be conveniently sealed by tying a knot.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a food preservation bag, comprising a bag body, wherein one side of the bag body is an open bag opening, and the other three sides are closed sides. The bag body is provided with two overlapping binding strips, and the two binding strips are located on one of the closed sides of the bag opening. The same side of the two binding strips is integrally connected to the closed side of the bag body, and the connection includes a direct connection part and an easy-tear line. The direct connection part is located at the end of the binding strip near the bag opening, and the easy-tear line extends from the direct connection part to the end of the binding strip away from the bag opening.

[0005] Furthermore, a fixing piece is provided on the other closed side of the bag body opposite to the binding piece, and the fixing piece is provided with a perforation.

[0006] Furthermore, the fixing piece is located near the bag opening.

[0007] Furthermore, the bag body includes two plastic wraps, and the three sides of the two plastic wraps are heat-sealed to form closed sides. One of the closed sides separates a binding piece, and the opposite closed side is heat-sealed to form a fixing piece.

[0008] Furthermore, the width of the fixing piece is greater than the width of the heat-sealed side, and the perforation is greater than that of the binding piece.

[0009] Furthermore, the perforation is a cut slit.

[0010] Compared with the prior art, the food preservation bag has the advantages that: the food is put into the bag body through the bag opening, when the bag opening needs to be closed, the bundling pieces are pulled apart through the easy-tear line between the bag body, two independent bundling pieces are formed after being pulled apart, then the end of one of the bundling pieces is inserted through the perforation on the fixing piece and is knotted with the other bundling piece, the bag opening is retracted during the knotting process, and the bag opening is closed after knotting, so that the bag opening is conveniently closed through the knotting mode, labor is saved, and the preservation effect on the food is ensured.
