[0012] like Figure 1 and Figure 2As shown, a degradable and recyclable chewing gum outer wrapping paper includes a main reference paper layer 1, which serves as the main reference structure of the wrapping paper and can ensure the overall structural strength and basic protective performance. An ink layer 2 is provided at the upper end of the main reference paper layer 1 to meet the printing requirements. A varnish protective layer 3 is provided at the upper end of the ink layer 2, and the varnish layer can ensure the barrier properties and safety of the outside. A glue coating 4 is provided at the lower end of the main reference paper layer 1, and a 6um VMPET layer 5 is provided at the lower end of the glue coating 4, which can ensure the overall reference toughness and protective properties and play a dual protective role. A circle of wavy pressure grooves is provided on the outer side of the lower end of the VMPET layer 5, which can enable a tighter packaging fit at the outer edge position during packaging. The main body reference paper layer 1 is made of paper weighing more than 60 grams, with a moisture permeability WVTR: ≤1 g / (m².day), 38°C, 90%RH; oxygen permeability OTR: ≤1 cm³ / (m².day. 0.1MPa), 23°C. The protective performance during use can be reliable, making the product warranty period of the chewing gum longer. The upper position of the main body reference paper layer 1 is provided with a V-shaped origami indentation groove 6 opening to the upper outside by means of a concave pressing method, which makes it easier to perform origami operations and has better accuracy. The bottom position is a flat reference structure, which ensures the overall external flatness of the structure. The upper outer edge position of the VMPET layer 5 is provided with a circle of groove structures 7 that extend beyond the outside for easy storage and folding, so that the edge position has better tightness during matching packaging or splicing. It is made of paper material with 6um VMPET as the base structure and a varnish layer. It has better overall barrier properties and better structural stability. It has a more reliable protective effect when in use. The packaging paper as a whole is easily degradable and recyclable, has better environmental performance, better overall hardness, and better cold sealing performance. It is more accurate and convenient when folding paper, and more reliable when sealing the outer position. It can provide better protection for chewing gum products and effectively reduce the production and use costs of packaging paper. It avoids the pollution of the existing packaging paper to the environment.

[0013] Preferably, the glue coating 4 is a barrier-type glue coating, which can make the overall barrier property better during use and the protective effect safer and more reliable during use.

[0014] Preferably, the main reference paper layer 1 is made of 70g paper, which is more convenient in production and easier to purchase. 80g paper can also be used to better increase the overall hardness and strength.

[0015] As a preferred choice, the barrier property is moisture permeability WVTR: ≤2 g / (m².day), 38℃, 90%RH; oxygen permeability OTR: ≤2 cm³ / (m².day. 0.1MPa), 23℃, ensuring reliable barrier performance during use, more stable protection performance during use, able to meet the use requirements in a variety of application environments, and a wider range of applications during use. The overall protection life during use is longer and the protection safety is higher.

[0016] Preferably, the outer side of the groove structure 7 exceeds the outer edge position of the VMPET layer 5, which makes the packaging or splicing of the outer position more convenient during use, and the matching convenience of the matching position is better. It can play the role of matching reference positioning, so that the outer position can form a more precise superposition match during matching, and the structural stability is also better.

[0017] Preferably, the origami indentation groove 6 and the indentation structure 7 are both formed by pressing through a spliced ​​mold, so that the position accuracy during pressing is better. The spliced ​​mold can be separated at the forming position to ensure that the structural processing in the width direction is more convenient and accurate.

[0018] 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.
