Abstract
Description
Technical Field
[0001] This application relates to the technical field of packaging bags, and in particular to an easy-tear small strip bag. Background Technology
[0002] The small strip packages divide the product into individual small packages, and then combine them into a "strip-shaped" whole that is easy to sell and carry.
[0003] Currently, the easy-tear small packets on the market are made of easy-tear PET / aluminum foil / easy-tear PE materials. They are easy to tear and do not require tearing. However, the PE tear at the tear point will produce a wavy shape due to stretching, making it difficult to empty the powder completely. In addition, because easy-tear PET has low tensile strength, it is easy to break the material during machine operation, making it difficult to produce and use. These issues need to be improved. Utility Model Content

[0006] By adopting the above technical solution, this application does not use PE material, and the easy-tear PET 30 layer ensures that the tear of the composite film will not produce a wavy shape, ensuring clean pouring; the reinforcing layer ensures the overall tensile strength of the composite film, ensuring the use of small strip packages.
[0007] Optionally, the reinforcing layer is a PET12 layer and the barrier layer is an AL9 layer.
[0008] By adopting the above technical solution, the PET12 layer has very high tensile strength after stretching, and it can withstand a lot of tension without easily breaking; the AL9 layer can effectively prevent the items in the containment cavity from getting damp and deteriorating, prevent oxygen from entering the containment cavity, and effectively block visible light.
[0009] Optionally, there are several tear points, and adjacent tear points are spaced apart.
[0010] By adopting the above technical solution, when one tear point breaks, another tear point allows the user to tear open the small package again, providing a guarantee. Users can also easily tear the small package from different locations on the packaging strip.
[0011] Optionally, the tear point break line is looped and surrounds the composite membrane.
[0012] By adopting the above technical solution, the ring-shaped tear line can guide users to tear open the small package more easily.
[0013] Optionally, the first heat-sealed zone may also be provided with the tear point break line.
[0014] By adopting the above technical solution, the tear point break at the first heat-sealed area makes it easier for users to tear open the first heat-sealed area, and the small packet is torn open more, making it easier to pour out the powder inside the small packet.
[0015] Optionally, there are two sets of tear point break lines, and the two sets of tear point break lines are located at both ends of the composite membrane.
[0016] By adopting the above technical solution, users can tear open the small package from both ends without needing to make a specific selection, which is quite convenient.
[0017] Optionally, the reinforcing layer is provided with a re-tear point break line, which is located between the tear point break line and one of the second heat-sealing zones, and the extension direction of the re-tear point break line is toward the tear point break line.
[0018] By adopting the above technical solution, after the user tears open the small package through the tear point, the user can tear it open again through the tear point, making the opening of the small package larger and making it easier to pour out the powder inside.
[0019] Optionally, there are at least two tear points, one of which extends perpendicularly to the tear point line, and the remaining tear points extend at an angle to the tear point line.
[0020] By adopting the above technical solution, users can tear the small package from different directions by breaking the thread at different tear points, and tear open openings of different sizes according to actual needs.
[0021] Optionally, the first heat-sealing area is provided with an easy-tear break line corresponding to the tear point break line. The extension direction of the easy-tear break line is the same as the extension direction of the tear point break line. The easy-tear break line penetrates the reinforcing layer, the printed layer, the barrier layer, and the easy-tear layer.
[0022] By adopting the above technical solution, the tear point break line plays a guiding role in tearing open the first heat seal area, allowing users to tear open the first heat seal area more easily.
[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. This application does not use PE material, and the easy-tear PET 30-layer ensures that the tear of the composite film will not produce a wavy shape, ensuring clean pouring; the reinforcing layer ensures the overall tensile strength of the composite film and ensures the use of small strip packages.
