Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment: see Figure 1 to Figure 3 , a new type of packaging bag, comprising a bag body 1, a tear line 2 is set on one corner of the bag body 1, and a cavity 3 filled with air is set on the bag body below the tear line 2. Due to the existence of air, the cavity has a certain degree of elasticity, which can make the part of the bag below the tear line always have a tendency to expand. When the bag is torn open along the tear line, the opening is in the cavity below. Under the action of the bag, it is stretched open, and the contents of the bag can be poured out conveniently.

[0018] The bag above the tear line 2 is provided with an elastic rubber band 4, and the rubber band 4 is in a stretched state. When the bag is pulled apart along the tear line, above the tear line The bag body shrinks automatically under the action of the rubber band. After the...

Abstract

The invention discloses a novel packaging bag. The novel packaging bag comprises a bag body; a tear line is arranged at one corner of the bag body; an elastic rubber band is arranged on the bag body located above the tear line; the rubber band is in a stretched state; when the bag body is pulled open along the tear line, the bag body above the tear line automatically contracts under the action of the rubber band; after the bag body above the tear line contracts, the opening cannot be blocked; and under the condition that the upper part of the opening is not teared off, things in the bag can also be tipped out.

Description

technical field [0001] The invention relates to a packaging bag and processing equipment for the packaging bag. Background technique [0002] When using the packaging bag containing salt, coffee and white sugar, it is necessary to tear a hole at one corner of the packaging bag so that the contents in the packaging can be poured out. But when tearing, if the part above the tear opening remains, it will block the opening of the bag, and there will be a barrier when pouring things. If the part above the opening is completely torn off, most people will discard the torn part at will, which will affect the appearance of the city, so it is necessary to change it. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a new type of packaging bag, which will not prevent the contents of the bag from being poured out without tearing off the part above the opening. [0004] Another object of the present invention is to provide ...
