Abstract
The invention discloses a food packaging material. The food packaging material is characterized in that the food packaging material comprises a freshness keeping layer, a flame retardation layer, a depletion layer and a thermal insulation layer, wherein the freshness keeping layer is connected with the flame retardation layer; the flame retardation layer is connected with the depletion layer; the depletion layer is connected with the thermal insulation layer; the material of the freshness keeping layer is PVDC; the material of the depletion layer is quicklime; and the material of the thermal insulation layer is an aluminum foil thermal-insulation coil. By adopting the above mode, the food packaging material has quality guaranteeing and freshness keeping functions, can heat a food through a match or a lighter anytime and anywhere, and greatly satisfies fast-paced people's needs.
Description
Technical field
The present invention relates to packaging for foodstuff field, relate in particular to a kind of packaging material for food.
Background technology
Nowadays, along with the quickening of people's rhythm of life, fast food industry is more and more flourishing, but because fast food is not eaten for a long time after buying and is caused it coldly to fall, due to the utensil that does not have at one's side to heat, need to wait until and go home could eat after heating, brought a lot of inconvenience to nowadays allegro worker.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of packaging material for food, and this material not only has Keep the quality and freshness function, can also by match or lighter, for food, heat anywhere or anytime, has greatly met fast rhythm of life people's needs.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of packaging material for food, comprising: fresh-keeping layer, flame-retardant layer, depletion layer and thermal insulation layer, and described fresh-keeping layer is connected with described flame-retardant layer;
Described flame-retardant layer is connected with described depletion layer;
Described depletion layer is connected with described thermal insulation layer.
In a preferred embodiment of the present invention, described fresh-keeping layer material is PVDC.
In a preferred embodiment of the present invention, described depletion layer material is quick lime.
In a preferred embodiment of the present invention, described insulating layer material is aluminium foil thermal insulating coiled material.
The invention has the beneficial effects as follows: a kind of packaging material for food of the present invention not only has Keep the quality and freshness function, can also by match or lighter, for food, heat anywhere or anytime, greatly met fast rhythm of life people's needs.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of packaging material for food of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, fresh-keeping layer; 2, flame-retardant layer; 3, depletion layer; 4, thermal insulation layer.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, the embodiment of the present invention comprises: a kind of packaging material for food, comprise: fresh-keeping layer 1, flame-retardant layer 2, depletion layer 3 and thermal insulation layer 4, described fresh-keeping layer 1 is connected with described flame-retardant layer 2, described fresh-keeping layer 1 material is PVDC, and PVDC material is safe to human body, can relievedly use, both can be used for fridge freshness retaining, also can be used for micro-wave oven.
Described flame-retardant layer 2 is connected with described depletion layer 3, thereby avoiding excess Temperature, described flame-retardant layer 2 cause fresh-keeping layer 1 burning destroyed, described depletion layer 3 materials are quick lime, and described quick lime reacts and can emit a large amount of heat with water, the potential safety hazard of having brought while having avoided with fire heating.
Described depletion layer 3 is connected with described thermal insulation layer 4, and described thermal insulation layer 4 materials are aluminium foil thermal insulating coiled material, and aluminium foil thermal insulating coiled material has the functions such as heat-insulation and heat-preservation, waterproof, protection against the tide.The absorptivity at sunshine (solar radiation absorbility factor) extremely low (0.07) of aluminium foil thermal insulating coiled material, has remarkable heat preservation and insulation, can reflect away more than 93% radiant heat.
Below the operation principle of a kind of packaging material for food of the present invention is described in detail.
When using; fresh-keeping layer 1 is for contact packing food; when needs heat; by thermal insulation layer 4 separation from packing; food is immersed to cold water just can heat all the other depletion layer 3 reactions; after having heated can also with thermal insulation layer 4 by boiling hot food together with pack pick up edible; thermal insulation layer 4 usually can also waterproof, protection against the tide; avoid causing because entering of water makes to react with depletion layer 3 food Automatic-heating; cause the waste of food, thereby flame-retardant layer 2 has prevented excess Temperature, cause fresh-keeping layer 1 burning destroyed.
Compared with prior art, a kind of packaging material for food of the present invention not only has Keep the quality and freshness function, can also by match or lighter, for food, heat anywhere or anytime, has greatly met fast rhythm of life people's needs.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
