[0001] This utility model relates to the field of food packaging technology, and in particular to a positioning heat-sealing coated high-barrier aluminized paper. Background Technology
[0002] Among existing food packaging papers, candy strip packaging paper is widely used. The structure of candy strip packaging is: film / printing / glue / paper / glue / aluminum foil. The overall structure is relatively complex, resulting in low efficiency and relatively high production costs during production and processing. It cannot be recycled or degraded, and its usage costs are also relatively high. In later use, it usually needs to be coated with positioning adhesive during heat sealing, which makes it relatively inconvenient to use and relatively low in packaging costs. Utility Model Content

It is recyclable and biodegradable, offering better environmental performance. During production, positioning adhesive is directly integrated into the aluminized paper structure, and a reinforcing ring is added to the outer edge, ensuring easier heat-sealing during use. No additional heat-sealing adhesive is needed during packaging, ensuring more precise alignment and reliable connection during heat sealing. It offers better barrier properties and protection, meeting the packaging needs of a wider range of food products. Furthermore, it ensures better sealing and packaging protection during use.

[0014] like Figure 1As shown, a high-barrier aluminized paper with a positioning heat-sealing coating includes a paper body structure 1, which is the main base structure of this packaging paper. The lower end of the paper body structure 1 is provided with an aluminized protective layer 2, which can replace a separate aluminum foil product in production and processing, resulting in lower overall cost and better biodegradability during later use. The upper end of the paper body structure 1 is provided with a barrier coating 3, which is applied by direct brushing, resulting in better overall barrier stability and lower overall processing cost. This avoids delamination during use and facilitates better biodegradability. A printed marking layer 4 is provided above the barrier coating 3, and a positioning adhesive layer 5 is provided above the printed marking layer 4. During production and processing, the positioning adhesive is directly applied to the main structure of the packaging paper as needed, ensuring better positioning accuracy and tighter fit during heat sealing. A wavy positioning reinforcement adhesive ring is provided around the outer edge of the printed marking layer 4 on the outer side of the positioning adhesive layer 5, ensuring better structural stability on the outer side during use and providing better overall protection during sealing. The thickness of the aluminized protective layer 2 is the same as the thickness of the main paper structure 1, making the main structure stronger, more tear-resistant, and more secure. The positioning structure on the positioning adhesive layer 5 is formed by secondary processing using a stepped structure, resulting in better stability, stronger load-bearing capacity, and more reliable packaging stability. This product adopts a film-free structure, making the overall structure simpler and allowing for recycling and degradation, thus improving environmental performance. During production, the positioning adhesive is directly integrated into the aluminized paper structure, and a reinforcing ring is set on the outer side, ensuring easier heat sealing during use. No additional heat-sealing adhesive is needed during packaging, ensuring more precise and secure connection during heat sealing. It offers better barrier properties and protection, meeting the packaging needs of a wider range of food products and ensuring better sealing and protection during packaging.
[0015] Preferably, the barrier coating 3 is an oil-based barrier coating structure. When the surrounding environment temperature is maintained at 76-85 degrees Celsius during the coating process, it can ensure better structural stability during coating processing, better overall protective barrier effect, longer protection time during use, and more reliable durability.
[0016] Preferably, the paper body structure 1 is made of coated paper with a strength of 40 g / m² ± 5%, which results in lower production and processing costs.
[0017] As a preferred option, it has an oxygen barrier of ≤2 cm3 / m².day·0.1MPa and a moisture barrier of ≤2 g / m².day, which can meet the protection and safety requirements in various application environments and has a wider range of applications.
[0018] Preferably, the positioning adhesive layer 5 is made of positioning wax, which provides better connection stability during use. It also offers scratch resistance and better heat-sealing performance.
[0019] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
