Description

Technical Field

[0001] The utility model relates to the technical field of food packaging bags, in particular to a partitioned packaging bag. Background Art

[0002] When packaging food, the packaging used should often be selected based on the characteristics of the packaged food and the application scenario. For example, it is necessary to consider whether the packaged food is fragile or easy to spill, and select packaging with cushioning or sealing properties that meet the use requirements to prevent the food from breaking or leaking. For example, considering the application scenario, for fresh food that needs to be transported over long distances, it is necessary to consider the strength and thermal insulation performance of the packaging. Conversely, for fresh food that needs to be transported over short distances, when the delivery personnel are equipped with container boxes, more emphasis is placed on the sealing and thermal insulation performance requirements of the fresh food packaging. For fresh food that easily precipitates liquid, such as freshly slaughtered fish or refrigerated fresh meat, the packaging materials commonly used in the current packaging process are mostly roll plastic bags for packaging food. At the same time, in order to take into account the freshness of such food, a layer of crushed ice is also placed in the plastic bag. For this type of fresh food that is prone to releasing liquid, the liquid released by the food is very easy to leak under this packaging method, or the liquid released by the food may leak together with the water from the melted ice, thereby contaminating other goods or clothing, containers, etc. Leakage is inevitable even if the food is wrapped in multiple layers of plastic bags. At the same time, since the water from the melted ice can directly contact the fresh food, the migration of water affects the quality and taste of the ingredients, and is also likely to cause contamination of the fresh food. Furthermore, this extensive multi-layer packaging method often wastes materials and is more likely to cause environmental pollution. Utility Model Content

[0003] The purpose of the utility model is to overcome the above problems existing in the prior art and to provide a compartmentalized packaging bag which is easy to use, has both food sealing performance and food preservation performance, and is beneficial to environmental protection.

The bag as claimed in claim 17, wherein the plurality of compartments are connected at least partially to form a plurality of compartments, wherein the plurality of compartments are connected at least partially to the bag. The plurality of compartments are connected at least partially to form a plurality of compartments. The plurality of compartments are connected at least partially to form a plurality of compartments.

[0006] Preferably, the compartmentalized packaging bag is folded along the compartmentalized heat-sealed portion after the contents are placed in the bag, so that the first chamber and the second chamber are in contact with each other.

[0007] Preferably, the volume of the first chamber is greater than the volume of the second chamber.

[0008] Preferably, the outer corners of the compartmentalized packaging bag are rounded.

[0009] Preferably, the inner corners of the compartmentalized packaging bag are rounded.

[0010] Preferably, the inner contour shape of the first chamber is the same as or similar to the shape of the contents of the first chamber.

[0011] Preferably, a tear-away notch is provided on a side edge of one side of the first chamber.

[0012] Preferably, a first printing area is provided on the outer side of the first chamber, and / or a second printing area is provided on the outer side of the second chamber.

[0013] Preferably, the width of the front material sheet of the first cavity is greater than the width of the rear material sheet; the width of the front material sheet of the second cavity is greater than the width of the rear material sheet.

[0014] According to the specific embodiments provided in this application, compared with the prior art, the present invention discloses the following technical effects:

[0015] The compartmentalized packaging bag provided in Example 1 of the present invention forms a pre-heat-sealing portion and a separating heat-sealing portion by heat sealing, and the bag chamber is separated into a first chamber and a second chamber by the separating heat-sealing portion. The rear heat-sealing portion is arranged at the top of the compartmentalized packaging bag, and is used to heat-seal the compartmentalized packaging bag after the contents are placed in the compartmentalized packaging bag. The heat-sealing portions are closely connected and can separate the bag chamber into different chambers that are isolated from each other and have sealing properties. After the first chamber is filled with fresh food that needs to be kept fresh and is prone to liquid precipitation, and the second chamber is filled with refrigeration material, the rear heat-sealing portion arranged at the top of the compartmentalized packaging bag can be heat-sealed to effectively separate the different contents: fresh food that is prone to liquid precipitation and refrigeration material.

[0016] At the same time, the compartmentalized packaging bag is also sealed and isolated from the external environment, thus avoiding the problem of mutual contamination between fresh food that is easy to precipitate liquid and refrigeration materials, and also avoiding the problem of liquid precipitated from food leaking to the outside world, or the problem of liquid precipitated from food leaking together with melted ice water and causing pollution.

[0017] Compared with the prior art which uses too much packaging material, the compartmentalized packaging bag provided by the present invention uses less material to achieve isolation and sealing between fresh food that is prone to liquid precipitation and refrigeration materials, thus having good environmental protection characteristics.

[0018] In addition, the compartmentalized packaging bag provided by the present invention is pre-set with a preheat sealing part and a separate heat sealing part before use. The operator can load fresh food that is easy to precipitate liquid and refrigeration materials into different chambers respectively. The operator only needs to heat-seal the rear heat sealing part on site to complete the complete closure of the compartmentalized packaging bag. Therefore, the compartmentalized packaging bag provided by the present invention is also easy to operate and use, which improves the packaging efficiency of fresh food that is easy to precipitate liquid.

[0019] Of course, any product implementing the present application does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
