Background technology
High temperature resistant boiling film is currently used a kind of packaging material for being used for boiling or cooking food, and it blocks water
Oxygen, high temperature resistant boiling, the characteristic of high intensity ensure that nutrition and the health of fast food, extend the shelf-life, and boiling film exists
During use, it is desirable to which while killing harmful bacteria in food at high temperature, and can does not destroy the structure of membrane material, will not yet
Harmful substance is produced, ensures the safety and sanitation of food；But existing common high temperature resistant boiling film is in 100 DEG C of temperature, although
Can holding structure it is complete, but vapor (steam) temperature therefore can cause such boiling film using process often more than 100 DEG C
In be easily peeled off, while separate out harmful substance.
The content of the invention
In view of the above-mentioned problems, the invention provides a kind of boiling film for packaging for foodstuff, it can be more than 100 DEG C in temperature
When holding structure stablize, be not easily stripped, without harmful substance separate out.
Its technical scheme is so：A kind of boiling film for packaging for foodstuff, it is lamination layer structure, from top to bottom successively
Including outer layer, middle level, internal layer, it is characterised in that：The outer layer is by enhancement layer and the composite bed for sealing layer stackup, the internal layer
It is immiscible between the enhancement layer and hot sealing layer, and pass through adhesive by hot sealing layer or/and to strengthen the composite bed of layer stackup
It is bonded, the boiling material that mass percent is 45% ~ 85% is contained in the hot sealing layer of the internal layer.
It is further characterized by：
The boiling material is medium density polyethylene（MDPE）, density range is 0.926g/cm3~0.940g/cm3；
The raw material that the middle level uses is nylon（PA）Or ethylene-vinyl alcohol copolymer（EVOH）；The side in the middle level is set
There is enhancement layer；
The raw material that the enhancement layer uses is nylon（PA）；The raw material that the hot sealing layer uses is polyethylene（PE）；The poly- second
Alkene（PE）With nylon（PA）, ethylene-vinyl alcohol copolymer（EVOH）Between it is immiscible, and be bonded by adhesive；
The percetage by weight that the outer layer, middle level, internal layer account for film gross weight is respectively 40% ~ 50%, 15% ~ 20%, 35% ~ 50%；
The thickness of the boiling film is 50 μm ~ 200 μm.
The invention has the advantages that the outer layer of boiling film is the composite bed by enhancement layer and heat-sealing layer stackup, internal layer is
By hot sealing layer or/and the composite bed of enhancing layer stackup, it is bonded between enhancement layer and hot sealing layer by adhesive, and in the heat of internal layer
Containing the boiling material that mass percent is 45%-85% in sealing, to improve the heat resistance of boiling film and intensity, it can make what is produced
Boiling film at 110 DEG C -115 DEG C can holding structure stablize, be not easily stripped, the precipitation without harmful substance.

The composite bed of enhancement layer and heat-sealing layer stackup, internal layer 3 are the composite bed by hot sealing layer or/and enhancing layer stackup, i.e. internal layer 3 is served as reasons
The composite bed of layer stackup is sealed, or internal layer 3 is the composite bed by hot sealing layer and enhancing layer stackup；Between enhancement layer and hot sealing layer
It is immiscible, and be bonded by adhesive, containing the boiling material that mass percent is 50%-80% in the hot sealing layer of internal layer 3, that is, exist
The polyethylene of internal layer 3（PE）In containing the high temperature resistant boiling material that mass percent is 50%-80%, boiling material is that French TOTAL is public
Take charge of the medium density polyethylene of production（MDPE）, density range is 0.926g/cm3~0.940g/cm3, the heat-resisting of boiling film can be improved
Property and intensity, specifically, the raw material that enhancement layer uses is nylon（PA）；The raw material that hot sealing layer uses is polyethylene（PE）；Middle level 2
For barrier layer, the raw material used is nylon（PA）Or ethylene-vinyl alcohol copolymer（EVOH）；The side in middle level 2 is provided with enhancing
Layer；Cost of material utilizes ethylene-vinyl alcohol copolymer to the middle resistance of the high barrier, nylon of oxygen to oxygen than relatively low
Every the high temperature resistant boiling characteristic of property, the high intensity of nylon, and boiling material, the boiling film free from extraneous odour that makes to produce, good toughness,
Intensity is high, the gas barrier property that blocks water is strong, high temperature resistant boiling, employs the boiling material of French Total companies production, while selects heat resistant type
