Technical Field

[0001] The invention relates to the technical field of food packaging, in particular to a positioning coated chewing gum packaging outer paper. Background Art

[0002] The existing candy bar packaging structure adopts dispensing / film / printing / glue / paper / glue / aluminum foil. The overall structure during production and processing is relatively complex, and the production and processing cost is relatively high. During use, dispensing settings need to be performed when packaging candies. The efficiency during use is relatively low. When in use, the aluminum foil layer is the inner side of the packaging, and the visual effect during packaging is relatively poor. When in use, the heat sealing performance is relatively ordinary, the sun protection effect is relatively poor, and the wear resistance during use is also relatively poor. Summary of the invention

[0003] The purpose of the present invention is to provide a positioning coated chewing gum packaging outer paper, which adopts a brand-new structural design. The positioning glue is directly integrated on the packaging outer paper during production, which is more convenient to use. By arranging the aluminum foil surface on the outside, the outside has a better packaging visual effect when in use, and the overall heat sealing property when in use is better. The overall wear resistance of the printing layer is better, and it has reliable light-fast performance when in use. The protective effect when in use is more guaranteed, the overall durability is stronger, and it can meet the protection and use needs in relatively poor application environments.

[0004] The technical solution of the present invention is as follows: A positioning coated chewing gum packaging outer paper, characterized in that it includes a coated paper layer, a glue layer is evenly coated on the upper end of the coated paper layer, an aluminum foil layer is arranged on the upper end of the glue layer, the upper end of the aluminum foil layer is a printing layer, a positioning glue layer is arranged on the upper end of the printing layer, a staggered and fused forming step structure is arranged at the matching position between the positioning glue layer and the printing layer, the forming step structure is formed by printing, the positioning glue on the positioning glue layer is formed by two layers of different glues, the positioning glue layer is processed by positioning wax, and the printing layer is printed by varnish and ink.

[0005] Furthermore, the glue used in the glue layer is a water-based polyurethane adhesive.

[0006] Furthermore, the glue layer is provided with two layers. After the first layer of glue is evenly applied, it is left to stand for 10 minutes at room temperature before applying the second layer. The application thickness of the first layer and the second layer is the same.

[0007] Furthermore, the coated paper layer is made of coated paper 40 g / square ± 5%.

[0008] Furthermore, the light fastness grade is 6, the friction coefficient (AL / AL) is 0.25~0.45, and the heat seal strength is destructive tearing.

[0009] Beneficial effects of the present invention: The present invention adopts a brand-new structural design, and the positioning glue is directly integrated and set on the outer paper of the packaging during production, which is more convenient when used. By setting the aluminum foil surface on the outside, the outside has a better packaging visual effect when used, and the overall heat sealing property is better when used, the overall wear resistance of the printing layer is better, and it has reliable light resistance when used. The protective effect when used is more guaranteed, the overall durability is stronger, and it can meet the protection use requirements of relatively poor application environments. The processing efficiency during production and processing is higher, and the production cost is lower. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the present invention; In the figure: 1. coated paper layer, 2. glue layer, 3. aluminum foil layer, 4. printing layer, 5. positioning glue layer. DETAILED DESCRIPTION

[0011] like Figure 1 As shown, a positioning coated chewing gum packaging outer paper comprises a coated paper layer 1, the upper end of the coated paper layer 1 is evenly coated with a glue layer 2, and the upper end of the glue layer 2 is provided with an aluminum foil layer 3. When in use, this structure is located outside to ensure better glossiness of the outer layer. The upper end of the aluminum foil layer 3 is a printing layer 4, which can be used to set the content to be printed. The upper end of the printing layer 4 is provided with a positioning glue layer 5, which ensures greater convenience in later use, higher position accuracy during setting, better matching accuracy during later use, and more reliable stability during connection and matching. The positioning glue layer 5 and the printing layer 4 are provided with a staggered and fused forming step structure at the matching position, and the forming step structure is formed by printing. The positioning glue on the positioning glue layer 5 is formed by two layers of different glues, and the positioning glue layer 5 is processed by positioning wax, which has better connection stability when in use. It has scratch resistance and better heat sealing performance when in use. The printing layer 4 is printed with varnish and ink to ensure better wear resistance of the printing layer, and more reliable printing clarity and durability when in use. The outer paper of this packaging adopts a brand-new structural design. The positioning glue is directly integrated on the outer paper of the packaging during production, which is more convenient when used. By setting the aluminum foil surface on the outside, the outside has a better packaging visual effect when used, and the overall heat sealing property during use is better. The overall wear resistance of the printing layer is better, and it has reliable sun-fast performance during use. The protective effect during use is more guaranteed, and the overall durability is stronger, which can meet the protection needs of relatively poor application environments.

[0012] Preferably, the glue used in the glue layer 2 is a water-based polyurethane adhesive, and can be a water-based glue product commonly used in the prior art, such as Vistaclea TR17 E, SPEA105, etc.

[0013] Preferably, the glue layer 2 is provided with two layers. After the first layer of glue is evenly applied, the second layer is applied after standing at room temperature for 10 minutes. The first layer and the second layer have the same application thickness, which can make the bonding and fastening between the upper coated paper and the glue layer better, the durability during use is more reliable, and it is not easy to separate during long-term use, which makes the service life of the paper longer and the warranty period when it is not used after processing is longer.

[0014] Preferably, the coated paper layer 1 is made of coated paper 40 g / sq.±.5%, which has lower production costs and can meet a wider range of food packaging requirements.

[0015] Preferably, the light fastness grade is 6, the friction coefficient AL / AL is 0.25-0.45, and the heat sealing strength is destructive tearing.

[0016] 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.
