The utility model comprises the paper-carrier boxboard, the first glue-line, thermal insulation layer, the second glue-line and the aluminizer internal layer that set gradually from outside to inside; Described paper-carrier boxboard and thermal insulation layer are by the first glue-line gummed, and described thermal insulation layer and aluminizer internal layer are by the second glue-line gummed.
The thickness of described paper-carrier boxboard is 2～50mm.
Described the first glue-line and the second glue-line are white glue with vinyl or thermosol; The thickness of described the first glue-line is 0.5～3 μ m, and the thickness of the second glue-line is 0.5～3 μ m.
The material of described thermal insulation layer is cellucotton or cloth, and thickness is 0.5～30mm.
The material of described aluminizer internal layer is PET aluminizer or OPP aluminizer, and thickness is 0.5～30 μ m.
The utility model also comprises aluminizer skin and the 3rd glue-line; Described aluminizer skin is arranged on paper-carrier boxboard outside, and glues together by the 3rd glue-line with paper-carrier boxboard.
The 3rd described glue-line is white glue with vinyl or thermosol, and thickness is 0.5～3 μ m.
The outer field material of described aluminizer is PET aluminizer or OPP aluminizer, and thickness is 0.5～30 μ m.
The beneficial effects of the utility model:
1, the utlity model has good heat insulation, fresh-keeping effect; Can be in summer for the refrigeration of fresh food, also can be in the winter time for the insulation of hot food; In transportation, keep fresh especially for fresh food;
2, the utility model can be used as the material of Freshness-retaining packing container, and this Freshness-retaining packing container can adopt conventional carton device fabrication.
Brief description of the drawings
Fig. 1 is the overall structure schematic diagram of the utility model in embodiment 1;
Fig. 2 is the overall structure schematic diagram of the utility model in embodiment 2.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1:
As shown in Figure 1, heat insulation fresh-keeping paperboard comprises the paper-carrier boxboard 1, the first glue-line 2, thermal insulation layer 3, the second glue-line 4 and the PET aluminizer internal layer 5 that set gradually from outside to inside; Paper-carrier boxboard 1 glues together by the first glue-line 2 with thermal insulation layer 3, and thermal insulation layer 3 glues together by the second glue-line 4 with PET aluminizer internal layer 5.The thickness of paper-carrier boxboard 1 is 2～50mm; The first glue-line 2 and the second glue-line 4 are white glue with vinyl; The thickness of the first glue-line 2 is 0.5～3 μ m, and the thickness of the second glue-line 4 is 0.5～3 μ m; The material of thermal insulation layer 3 is cellucotton, and thickness is 0.5～30mm; The thickness of PET aluminizer internal layer 5 is 0.5～30 μ m.
The PET aluminizer internal layer 5 of this heat insulation fresh-keeping paperboard can reflect heat energy, and thermal insulation layer 3 plays good insulation effect.This heat insulation fresh-keeping paperboard is made into Freshness-retaining packing container, when refrigerate fresh food summer, ice cube can be placed in Freshness-retaining packing container, the cold that thermal insulation layer 3 is blocked ice cube distributes, and PET aluminizer internal layer 5 reflects external heat, is specially adapted to fresh food and in transportation, keeps fresh; Winter, while being used for the insulation of hot food, PET aluminizer internal layer 5 reflected internal heat energy, and thermal insulation layer 3 intercept heat are distributed.
Embodiment 2:
As shown in Figure 2, heat insulation fresh-keeping paperboard comprises the PET aluminizer skin 6, the 3rd glue-line 7, paper-carrier boxboard 1, the first glue-line 2, thermal insulation layer 3, the second glue-line 4 and the PET aluminizer internal layer 5 that set gradually from outside to inside; PET aluminizer outer 6 glues together by the 3rd glue-line 7 with paper-carrier boxboard 1; Paper-carrier boxboard 1 glues together by the first glue-line 2 with thermal insulation layer 3, and thermal insulation layer 3 glues together by the second glue-line 4 with PET aluminizer internal layer 5.The thickness of paper-carrier boxboard 1 is 2～50mm; The first glue-line 2, the second glue-line 4 and the 3rd glue-line 7 are white glue with vinyl; The thickness of the first glue-line 2 is 0.5～3 μ m, and the thickness of the second glue-line 4 is 0.5～3 μ m, and the thickness of the 3rd glue-line 7 is 0.5～3 μ m; The material of thermal insulation layer 3 is cellucotton, and thickness is 0.5～30mm; The thickness of PET aluminizer skin 6 is 0.5～30 μ m, and the thickness of PET aluminizer internal layer 5 is 0.5～30 μ m.
