[0014] like Figure 1 and Figure 2As shown, a tearable package for cigarette strips includes a main body reference protection layer 1, and a transparent heat-sealed positioning coating 2 is provided at the upper end of the main body reference protection layer. The main body reference protection layer 1 is a transparent structure to ensure reliable permeability during packaging. The lower end of the main body reference protection layer 1 is a printing coating 3, which can print the content that needs to be printed, and can ensure that the printing layer has reliable durability during use and will not fall off during use. The lower end of the printing coating 3 is an indentation layer 4, and the lower end of the indentation layer 4 is bonded with an aluminum foil layer 6 through a glue layer 5, so that the overall protection is better and has more reliable barrier properties. The transparent heat-sealed positioning coating 2 is composed of two positioning areas that are opposite to each other and form a rectangular shape, and can be positioned and matched with the packaged cigarettes as a whole during automatic packaging. The main body reference protection layer 1 is located at the packaging position of two boxes of cigarettes and is provided with tearable matching holes distributed along the rear circle of the packaging. The tearable matching holes are located just above the indentation position of the indentation layer 4, which can ensure that the corresponding position can be accurately and safely torn open during later use. The transparent heat-sealed 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 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, and the cost of the overall packaging process is lower. It can be used with automated tightening packaging equipment for automated packaging, and the overall efficiency during packaging is higher. The surface layer adopts an indentation process, which can easily separate every two boxes of cigarettes during use, and the convenience of consumers is stronger. 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, and can provide better safety protection for packaged products, and the overall production cost is lower.
[0015] Preferably, the main reference protective layer 1 is made of PET material, and the transparent heat-sealing positioning coating 2 is a water-based acrylic system, which has better durability during use, more reliable overall structural stability, and is easier to be firmly connected to each other during production. Preferably, PET 15u±4%, positioning heat-sealing glue 2g / square±0.5g, Alu 7u±4% can be used, which can reduce the overall material cost and make the materials easier to purchase.
[0016] Preferably, after packaging, the end positions of the length direction of the cigarette strip package 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.
[0017] The barrier properties are moisture permeability WVTR: ≤2 g / (m².day), 23℃, 85%RH; oxygen permeability OTR: ≤2 cm³ / (m².day. 0.1MPa), 23℃, 85%RH; the coating accuracy of the transparent heat-sealing positioning coating 2 is: ≤±0.3mm, the sealing temperature is: 100℃, and the heat-sealing strength is: ≥4 N / 15mm, which can ensure reliable barrier performance during use, more stable protective performance during use, can meet the use requirements in various application environments, and has a wider range of applications during use.
[0018] 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.
[0019] 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.
[0020] 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 of the present invention. These improvements or substitutions should also be regarded as the scope of protection of the present invention.
