Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, and in particular to an easily degradable and recyclable outer packaging paper for chewing gum. Background Technology

[0002] Currently, the outer packaging structure of chewing gum is: 12um PET / printing / glue / 30g paper / glue / 13um LDPE / 7um AL. The overall structure is relatively complex, making the processing difficult and the production cost relatively high. The folding precision is poor, and it cannot meet the requirements for recycling and degradation in later use. Folding multiple pieces of chewing gum on the same paper is also quite difficult. Utility Model Content

[0003] The purpose of this invention is to provide a biodegradable and recyclable outer packaging paper for chewing gum. It is made of paper material combined with 6um VMPET as the base structure and a varnish layer, resulting in better overall barrier properties and structural stability. This provides more reliable protection during use. The packaging paper is biodegradable and recyclable, with better environmental performance, higher overall rigidity, and better cold-sealing performance. It also offers greater precision and convenience when folding and more reliable sealing of the outer parts, providing better protection for chewing gum products and effectively reducing the production and use costs of the packaging paper.

[0004] The technical solution of this utility model is as follows:

[0005] A biodegradable and recyclable chewing gum outer packaging paper includes a main base paper layer, characterized in that: an ink layer is provided at the upper end of the main base paper layer, a varnish protective layer is provided at the upper end of the ink layer, an adhesive coating is provided at the lower end of the main base paper layer, a 6µm VMPET layer is provided at the lower end of the adhesive coating, and a wavy groove is provided on the outer side of the lower end of the VMPET layer. The main base paper layer is made of paper with a weight greater than 60 grams, and has a moisture permeability (WVTR): ≤1 g / (m².day), 38℃, 90%RH; and an oxygen permeability (OTR): ≤1 cm³ / (m².day. 0.1MPa), 23℃. A V-shaped folding groove with an opening facing upwards and outwards is provided at the upper position of the main base paper layer, and a groove structure extending beyond the outer edge of the upper outer edge of the VMPET layer is provided for easy storage and folding.

[0006] Furthermore, the adhesive coating is a barrier adhesive coating.

[0007] Furthermore, the main reference paper layer uses 70-gram paper.

[0008] Furthermore, the barrier properties are: moisture permeability (WVTR): ≤2 g / (m².day), 38℃, 90%RH; oxygen permeability (OTR): ≤2 cm³ / (m².day. 0.1MPa), 23℃.

[0009] Furthermore, the outer side of the groove structure extends beyond the outer edge of the VMPET layer.

[0010] Furthermore, both the origami creasing groove and the creasing groove structure are formed by pressing with a splicing mold.

[0011] The beneficial effects of this utility model are:

[0012] This invention combines paper material with 6um VMPET as the base structure and a varnish layer, resulting in better overall barrier properties and structural stability. This provides more reliable protection during use. The packaging paper is easily degradable and recyclable, offering better environmental performance, higher overall rigidity, and better cold-sealing properties. It also improves the precision and convenience of folding and ensures tighter sealing of the outer parts, providing better protection for chewing gum products and effectively reducing the production and usage costs of the packaging paper.

[0016] like Figure 1 and Figure 2As shown, a biodegradable and recyclable chewing gum outer packaging paper includes a main base paper layer 1, which serves as the main base structure of the packaging paper, ensuring overall structural strength and basic protective performance. An ink layer 2 is provided at the upper end of the main base paper layer 1 to meet printing requirements. A varnish protective layer 3 is provided at the upper end of the ink layer 2, ensuring barrier properties and safety on the outer side. An adhesive coating 4 is provided at the lower end of the main base paper layer 1, and a 6µm VMPET layer 5 is provided at the lower end of the adhesive coating 4, ensuring overall base toughness and protection, providing dual protection. A wavy groove is provided at the lower outer edge of the VMPET layer 5, allowing for a tighter seal at the outer edge during encapsulation. The main reference paper layer 1 uses paper with a weight greater than 60 grams, and has a moisture permeability (WVTR) of ≤1 g / (m².day), 38℃, 90%RH; and an oxygen permeability (OTR) of ≤1 cm³ / (m².day. 0.1MPa), 23℃. This ensures reliable protection during use and extends the product shelf life of the chewing gum. The upper part of the main reference paper layer 1 features a V-shaped folding groove 6 with an upward and outward opening, making folding easier and more precise. The bottom is a flat reference structure, ensuring overall structural flatness. The upper outer edge of the VMPET layer 5 has a groove structure 7 that extends beyond the outer edge for easy folding and storage, improving the tightness of the edge during sealing or splicing. It is constructed using paper material combined with 6µm VMPET as the base structure and a varnish layer, resulting in better overall barrier properties and structural stability. This leads to more reliable protection during use. The packaging paper is also biodegradable and recyclable, offering better environmental performance, increased overall rigidity, and improved cold-sealing properties. It also provides greater precision and convenience during folding and more reliable sealing of the outer parts, offering superior protection for chewing gum products and effectively reducing production and usage costs. This avoids the environmental pollution associated with existing packaging papers.

[0017] Preferably, the adhesive coating 4 is a barrier type adhesive coating, which can improve the overall barrier properties during use and make the protective effect safer and more reliable.

[0018] Preferably, the main reference paper layer 1 uses 70-gram paper, which is more convenient to produce and the paper material is easier to purchase. Alternatively, 80-gram paper can be used, which can better increase the overall hardness and strength.

[0019] Preferably, the barrier properties are: moisture permeability WVTR: ≤2 g / (m².day), 38℃, 90%RH; oxygen permeability OTR: ≤2 cm³ / (m².day, 0.1MPa), 23℃. This ensures reliable barrier performance during use, more stable protective performance, and the ability to meet the needs of various application environments, thus broadening its application range. It also provides a longer overall protective lifespan and higher protective safety.

[0020] Preferably, the outer side of the groove structure 7 extends beyond the outer edge of the VMPET layer 5, making the encapsulation or splicing operation of the outer position more convenient during use, improving the ease of fitting, and serving as a positioning reference. This allows for a more precise superimposed fit when the outer position is fitted, resulting in better structural stability.

[0021] Preferably, both the origami creasing groove 6 and the creasing structure 7 are formed by pressing with a splicing mold, which makes the positional accuracy during pressing better. The splicing mold can be separated at the forming position, ensuring that the structure processing in the width direction is more convenient and accurate.

[0022] 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.
