Description

Technical Field

[0001] This utility model relates to the field of packaging bags, and in particular to a reusable tamper-evident packaging bag. Background Technology

[0002] With the advancement of technology, people have increasingly higher requirements for the security of documents, document bags, and packaging bags. Currently, existing packaging bags, such as cash bags, express delivery bags, court evidence bags, and bags for exam papers, confidential documents, and controlled drugs, have tamper-evident labels affixed to their openings. These labels are affixed to both sides of the bag opening. To retrieve the contents, the tamper-evident label is peeled off, exposing the bag opening. However, these labels are usually firmly attached, and peeling them off can easily tear the bag opening, making it difficult to reuse the bag for storing items. Furthermore, after removing the tamper-evident label, if items need to be put back in, additional tape must be used to seal the bag opening to prevent items from falling out. In other words, the packaging bags are not easily reusable. Therefore, it is necessary to create a reusable tamper-evident packaging bag to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a reusable tamper-evident packaging bag to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A reusable tamper-evident packaging bag includes a front side of the bag body, a back side of the bag body, an extension area, a sealing strip, and a tamper-evident label. The front side of the bag body is glued to the front side of the back side of the bag body, and the upper ends of the front and back sides of the bag body form the bag opening. The sealing strip is fixed inside the bag opening in a transverse direction. The lower end of the extension area is connected to the upper end of the back side of the bag body. The tamper-evident label is fixed in a transverse direction to the front side of the upper end of the extension area. The extension area has a tear line in a transverse direction, and the tear line corresponds to the area between the sealing strip and the tamper-evident label.

[0006] Further description of this utility model: The front of the bag body is provided with a scale area, which includes a metric scale area and an imperial scale area arranged side by side.

[0007] Further description of the present invention: Two sets of tear lines are provided on the extension area, and an easy-tear strip is formed between the two sets of tear lines.

[0008] Further description of the present invention: The front of the bag body is provided with an alignment line, which is arranged horizontally and corresponds to the bottom of the sealing strip.

[0009] Further description of the present invention: The distance from the upper edge of the extension area to the upper set of tear lines is equal to the distance from the alignment line to the lower set of tear lines.

[0010] Further description of the present invention: The tamper-evident label includes a VOID anti-transfer strip and a surface anti-adhesive film. The VOID anti-transfer strip is pasted horizontally on the upper front side of the extension area, and the surface anti-adhesive film covers the front side of the VOID anti-transfer strip.

[0011] The beneficial effects of this utility model are as follows: The item to be packaged is placed into the sealed bag through the opening, then the sealing strip is pressed to close the bag. The upper end of the extension section is folded forward and a tamper-evident label is attached to the front of the bag, thus obscuring the bag opening and preventing direct removal of the item. Forcibly tearing off the tamper-evident label will leave a mark on the front of the bag, thus achieving the effect of preventing tampering. When it is necessary to retrieve the item, the extension section is torn along the tear line, removing the obstruction of the bag opening. The sealing strip is then opened to remove the item. The advantages of this design are: by setting a tear line, the tamper-evident label is avoided when removing the item, thus keeping the front, back, and opening of the bag intact; and by setting a sealing strip, the bag opening can be repeatedly opened and closed, allowing the packaging bag to be reused.

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0016] like Figure 1 As shown, a reusable tamper-evident packaging bag includes a front side 01, a back side 02, an extension area 03, a sealing strip 04, and a tamper-evident label 05. The front side 01 is adhered to the front side of the back side 02. The upper ends of the front side 01 and the back side 02 form a bag opening 06. The sealing strip 04 is fixed laterally inside the bag opening 06. The lower end of the extension area 03 is connected to the upper end of the back side 02. The tamper-evident label 05 is fixed laterally to the front side of the upper end of the extension area 03. The extension area 03 has a tear line 032 along the transverse direction, which corresponds to the area between the sealing strip 04 and the tamper-evident label 05.

[0017] The items to be packaged are placed into the sealed bag through the opening 06. Then, the sealing strip 04 is pressed to seal the opening 06. The upper end of the extension area 03 is folded forward and then attached to the front side of the front 01 of the bag body through the tamper-evident label 05. This causes the extension area 03 to cover the opening 06, making it impossible to take the items out of the bag directly from the opening 06. If the tamper-evident label 05 is forcibly removed, it will leave a mark on the front 01 of the bag body. Therefore, it can achieve the effect of preventing the packaging bag from being tampered with. When it is necessary to retrieve the items from the bag, the extension area 03 is torn open from the tear line 032, so that the extension area 03 no longer covers the opening 06. Then, the sealing strip 04 is opened, and the items from the bag can be taken out. The advantages of this design are: by setting a tear line 032, the anti-tamper label 05 is not torn directly when the item is taken out, so that the front 01, back 02 and opening 06 of the bag remain intact. Furthermore, by setting a sealing strip 04, the opening 06 can be repeatedly opened and closed, so that the packaging bag can be reused.

[0018] The front 01 of the bag body is provided with a scale area 011, which includes a metric scale area 011 and an imperial scale area 011 arranged side by side. When packaging objects, the size of the objects can be easily measured through the scale on the scale area 011, and the scale area 011 is provided with both metric and imperial scale areas, allowing for flexible selection of the measurement unit.

[0019] Two sets of tear lines 032 are provided on the extension area 03, and an easy-tear strip 031 is formed between the two sets of tear lines 032. The easy-tear strip 031 makes it easier to break the extension area 03 from the middle and is less likely to cause deformation of the extension area 03.

[0020] The front 01 of the bag body is provided with an alignment line 012, which is set horizontally and corresponds to the lower part of the sealing strip 04. By setting the alignment line 012, it is easy to find the correct affixing position of the tamper-evident label 05 during packaging.

[0021] The distance from the upper edge of the extended area 03 to the upper set of tear lines 032 is equal to the distance from the alignment line 012 to the lower set of tear lines 032. This arrangement ensures that after the tamper-evident label 05 is affixed according to the alignment line 012, the easy-tear strip 031 is positioned at the top of the packaging bag, facilitating its removal.

[0022] The tamper-evident label 05 includes a VOID anti-transfer strip 051 and a surface anti-adhesion film 052. The VOID anti-transfer strip 051 is pasted horizontally on the upper front side of the extension area 03, and the surface anti-adhesion film 052 covers the front side of the VOID anti-transfer strip 051.

[0023] VOID Anti-Transfer Label 051, also known as VOID Anti-counterfeiting Label, is a peel-off type (leaving text when peeled off) anti-counterfeiting label that prevents unauthorized removal, movement, and reapplication. It is commonly used in logistics labels, anti-theft seals, and other sealing applications. VOID anti-counterfeiting labels are destroyed upon removal, ensuring authenticity and enabling automatic detection.

[0024] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
