[0002] When packing cigarettes in cartons, a multi-layer packaging structure is usually required to cooperate with each other to complete the packaging of cigarettes in cartons. At present, the packaging of cigarettes in cartons is handmade packaging boxes, and transparent heat-sealed shrink BOPP is added for overall packaging. The structure of the handmade packaging boxes is relatively complex, and more materials are used. There is over-packaging in the packaging process, and the overall packaging price is relatively high. Heat-sealed BOPP is not only expensive, but also difficult to produce. The efficiency of the packaging process is relatively low, and the overall packaging cost is also relatively high.

[0018] like Figure 1 and Figure 2The figure shows an easy-tear package for cigarette strips. It includes a main base protective layer 1, with a transparent heat-seal positioning coating 2 applied to its upper end. The main base protective layer 1 is transparent, ensuring reliable permeability during packaging. The lower end of the main base protective layer 1 is a printing coating 3, which can be printed with the required content. This ensures the durability of the printed layer and prevents it from falling off during use. The lower end of the printing coating 3 is an indentation layer 4, which is bonded to an aluminum foil layer 6 via a glue layer 5, enhancing overall protection and providing more reliable barrier properties. The transparent heat-seal positioning coating 2 consists of two opposing positioning areas that form a rectangular shape, ensuring overall positioning and alignment with the packaged cigarettes during automated packaging. The main base protective layer 1 is provided with easy-tear holes distributed along the rear edge of the package, located at the two cigarette packing locations. These easy-tear holes are located directly above the indentation of the indentation layer 4, ensuring precise and safe tearing during later use. The transparent heat-seal positioning coating 2 is provided with a black cursor, which can cooperate with the automated packaging equipment for photoelectric identification, so that the precision of the fixed-point packaging is higher and the overall packaging effect is more guaranteed. This product adopts a single-layer packaging structure to replace the existing multi-layer manual packaging, which reduces the cost of the overall packaging process and can be used with automated tightening packaging equipment for automated packaging, which has higher overall efficiency during packaging. The surface adopts an indentation process to easily separate each two boxes of cigarettes during use, which is more convenient for consumers to use. The packaging structure that can adopt a multi-layer composite coating not only avoids excessive packaging, but also effectively guarantees the printing effect and overall barrier properties, can better protect the packaged products, and has lower overall production costs.

[0019] Preferably, the main body reference protective layer 1 is made of PET, and the transparent heat-seal positioning coating 2 is a water-based acrylic system. This provides improved durability during use, greater overall structural stability, and easier and more secure connection during production. Preferably, PET 15u ± 4%, positioning heat-seal adhesive 2g / square ± 0.5g, and Al 7u ± 4% can be used, which can reduce overall material costs and make materials more readily available.

[0020] Preferably, after packaging, the end positions of the cigarette strip packages in the longitudinal direction are pressed and connected together in a trapezoidal staggered stacking manner, so that the overall protection effect of the end positions is better, the matching operation during packaging is more convenient, and the end matching connection is safer.

[0021] The barrier properties are: moisture permeability (WVTR): ≤2 g / (m².day), 23°C, 85%RH; oxygen permeability (OTR): ≤2 cm³ / (m².day. 0.1MPa), 23°C, 85%RH; the coating accuracy of the transparent heat-seal positioning coating 2 is ≤±0.3mm, the sealing temperature is 100°C, and the heat-seal strength is ≥4 N / 15mm. These ensure reliable barrier performance during use, more stable protective performance during use, and can meet the use requirements in various application environments, thus extending its application range.

[0022] Preferably, the printed coating 3 is provided with a golden marking area around the easy-tear matching hole, which can mark the easy-tear area more clearly, making it more convenient for consumers to use it later.

[0023] Preferably, the position deviation of the indentation layer 4 is ≤±0.3 mm, which provides better safety during subsequent tearing and will not affect surrounding structures. If the deviation is too large, it will affect the structure of the surrounding connection positions during the tearing process.

[0024] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles described in the present invention. These improvements or substitutions should also be regarded as the scope of protection of the present invention.
