Description
Technical field
The utility model discloses a kind of food packs, belong to packing articles technical field.
Background technique
Paying close attention to food safety always country or even the whole world is all the problem of paying much attention to, because this is to be related to life
The major issue of safety.Food packaging is used to protect food, and food is made to leave factory into the process of circulation in consumer's hand,
Prevent biology, chemical, physics foeign element damage.
There are many food packaging classification method.Such as it is divided by skill and technique: damp-prrof packing, waterproofing packing, mouldproof packaging, fresh-keeping packet
Dress, quick-frozen packaging, ventilative packaging, microwave disinfection packaging, aseptic packaging, gas flush packaging, vacuum packaging, Deoxygen Packaging, blister pack
Dress, skin packaging, stretch package, boil in bag packaging etc..
But either any manner of packing, it can all be related to two problems, shelf-life and preservation temperature, guarantee the quality
Phase is the food longest preservation time, and overdue preservation only results in food spoilage, and in addition excessively high and too low preservation temperature can also be led
Food properties variation or rotten damage are caused, if notification mechanisms are installed on strap, preservation temperature can be read from packaging bag
The information of degree and preservation time, feeds back by all means, it will is much less intermediate link, improves working efficiency.
Utility model content
In view of the above-mentioned problems existing in the prior art, it the purpose of this utility model is to provide a kind of food pack, adopts
With embedded photochromic layer structure, metachromasia is occurred according to temperature or time, detects food preservation environment, Real-time Feedback.
To realize that above-mentioned purpose of utility model, the technical solution adopted in the utility model are as follows:
A kind of food pack, including protective layer I, photochromic layer, substrate, glue-line and protective layer II, substrate using PET or
PI material, photochromic layer are set to substrate surface, photochromic layer using can not inversion off-color material, protective layer I is located at food pack
Outermost layer and be set to discoloration layer surface, I sealed air-tight of protective layer, glue-line be attached on substrate with equipped with discoloration level it is opposite
On one side, glue-line uses 3M glue material, installs matcoveredn II on glue-line, protective layer II is located at food pack innermost layer.
Preferably, the used off-color material of photochromic layer is temperature sensing material, and reaction discoloration takes place when temperature is higher than 15 °,
And metachromasia is irreversible, when temperature is increased to assigned temperature, i.e. generation metachromasia intuitively allows the external world to know environment temperature
It has been more than suitable preservation temperature, has made remedial measure in time, since metachromasia is irreversible, has also effectively prevented environment temperature
After recalling to, ignore the processing to preserved food.
Preferably, the used off-color material of photochromic layer contacts i.e. generation metachromasia with air, and reaction duration is no less than 3
Month, and metachromasia is irreversible, photochromic layer reaction time length can select system according to the food preservation phase, as time goes by, become
Metachromasia occurs for chromatograph, and photochromic layer color gradient becomes irreversible warning color after reaction thoroughly, due to for color gradient
And reaction is irreversible, effectively prevent due to the processing ignored to preserved food of slipping.
Preferably, the used puffing off-color material of photochromic layer, metachromasia occurs for packaging bag dilatancy, and changes colour
React irreversible, for compression packing food, rotten when occurring, air pressure is increased in packaging bag, and meeting dilatancy leads to photochromic layer
Metachromasia occurs.
Compared with prior art, the utility model has the beneficial effects that the photochromic layer structure embedded by design, is adopted respectively
It is anti-due to changing colour respectively to preservation temperature and food preservation time visual inspection with temperature-sensitive material and gradual change metachromasia material
It should be irreversible, ensure that foods caused by temperature fluctuation and expired disposition, it is whole using multilayer spacer structure, more
Food in good protective packaging bag.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the preferred embodiment of food pack provided by the utility model.
Specific embodiment
With preferred embodiment is made to the utility model further detailed complete illustrate with reference to the accompanying drawing.
Fig. 1 is a kind of preferred embodiment schematic diagram of food pack provided by the utility model.As shown in Figure 1, the food
Product packaging bag, a kind of food pack, including protective layer I 1, photochromic layer 2, substrate 3, glue-line 4 and protective layer II 5, substrate is adopted
With PET or PI material, photochromic layer 2 is set to 3 surface of substrate, photochromic layer 2 using can not inversion off-color material, protective layer I 1 is located at
Food pack outermost layer and it is set to 2 surface of photochromic layer, I 1 sealed air-tight of protective layer, glue-line 4 is attached on substrate 3 and is equipped with
The opposite one side in 2 face of photochromic layer, glue-line 4 use 3M glue material, and matcoveredn II 5 is installed on glue-line 4, and protective layer II 5 is located at food
Product packaging bag innermost layer.Photochromic layer 2 uses three kinds of off-color materials: one kind uses off-color material for temperature-sensitive material by photochromic layer 2
Reaction discoloration takes place when temperature is higher than 15 ° in material, and metachromasia is irreversible, and another kind is temperature sensing material, 2 institute of photochromic layer
I.e. generation metachromasia is contacted with air using off-color material, reaction duration is no less than 3 months, and metachromasia is irreversible, most
Latter, the used puffing off-color material of photochromic layer, metachromasia occurs for packaging bag dilatancy, and metachromasia can not
Inverse, for compression packing food, rotten when occurring, air pressure is increased in packaging bag, and meeting dilatancy causes photochromic layer to change colour
Reaction.
In implementation process, food is wrapped in innermost layer, is covered by protective layer II 5, II 5 one side preservation of protective layer food
On the other hand product protect the glue-line 4 of 3M glue material, prevent viscosity from dying down, the material of substrate 3 and glue-line 4 is all temperature insulating material, prevent
Only tearing, reaction occurs to early in I 1 effective protection photochromic layer 2 of protective layer, when starting preserved food, sealer I 1 is torn,
Metachromasia takes place in 2 ingress of air of photochromic layer, and after reaching certain temperature or specified duration, photochromic layer 2 can occur
Color change.
Compared with prior art, the utility model has the beneficial effects that the photochromic layer structure embedded by design, is adopted respectively
It is anti-due to changing colour respectively to preservation temperature and food preservation time visual inspection with temperature-sensitive material and gradual change metachromasia material
It should be irreversible, ensure that foods caused by temperature fluctuation and expired disposition, it is whole using multilayer spacer structure, more
Food in good protective packaging bag.
Be it is necessary to described herein finally: above embodiments are served only for making the technical solution of the utility model further
It explains in detail, should not be understood as limiting the scope of the invention, those skilled in the art is according to the present utility model
Some nonessential modifications and adaptations that above content is made all belong to the scope of protection of the present invention.
