Embodiment 1

[0013] like figure 1 As shown, the three-sealed bag is used as a packaging bag that can be opened and sealed repeatedly. The bag body 1 has three heat-sealing edges 2, and a long strip-shaped sealing strip 3 that can be lifted laterally is arranged above one side of the bag body. The sealing strip is made of resin. Made of material, it has self-adsorption ability and can be adsorbed on the bag body.

[0014] When the packaging bag is opened from the upper edge and needs to be sealed, the opening of the bag body can be folded towards the direction of the sealing strip, and the sealing strip can be lifted partially or completely, and then the folded opening is glued to the bag body with the sealing strip. To achieve the sealing of the packaging bag and the tightness of the packaging bag. When opening again, the package can be opened by opening the sealing strip first.

Embodiment 2

[0016] like figure 2 As shown, in this embodiment, a three-dimensional bag is used as a packaging bag that can be opened and sealed repeatedly. The bag body 1 has three sides heat-sealed edges 2, and an obliquely arranged above one side of the bag body and one end is a circular sealing strip 3. The method is the same as in Example 1.

Embodiment 3

[0018] like image 3 As shown, the bag body 1 has a heat-sealed edge 2, a seam is provided at the middle position of one side of the bag body, and a sealing strip 3 is vertically arranged at the seam. When in use, it is opened from the seam of the bag body and needs to be sealed, and the sealing strips are adhered to the bag body on both sides of the opening to seal the bag mouth.

Abstract

The invention relates to a packaging bag capable of being repeatedly opened and sealed. The packaging bag is characterized in that the packaging bag is provided with a sealing strip with the adsorption capacity, and the sealing strip can be arranged at the upper portion or the middle portion or the lower portion or the side face of a bag body. The packaging bag has the advantages that the structure is simple, operation is convenient, cost is low and the self-adsorption capacity is achieved; the packaging bag can be repeatedly opened and sealed, no glue exists on the sealing strip, using is safe and sanitary, and the repeated sealing effect is good.

Description

technical field [0001] The present invention relates to a packaging bag, in particular to a sealable packaging bag suitable for food packaging. Background technique [0002] At present, product packaging on the market, especially food packaging, does not have the function of repeated opening and closing. If the package cannot be eaten in time after opening, because it does not have a self-sealing function, the remaining food is easily damp and oxidized, thereby affecting the taste and flavor of the food. even corruption. [0003] In order to solve this problem, many companies have developed re-openable packaging products. For example, China Utility Model discloses a re-openable and closed packaging bag with an application number of 87204057. It is through two engageable card plates, with a layer of elastic material attached to the inner side. The edge of the packaging bag port is covered on this layer of elastic material and connected to the card plate. After the card plat...
