(C) after curing semi-finished product obtained in step (B) 48 hours at 50 DEG C between heat preservation, then die cut is to obtain afterwards Paper plastic-aluminum epiphragma finished product used for cosmetic.
Comparative example 2:
A kind of plastic-aluminum epiphragma used for cosmetic of this comparative example, outer layer 1 select that (PET film is with a thickness of 12 μm of PET film Refer to the film made of poly terephthalic acid class plastics, producer is Hangzhou great Hua Su industry Co., Ltd).
Aluminium foil layer 3 select with a thickness of 40 μm 8021 aluminium foils (trade mark be 8021 O state aluminium foil, manufacturer be middle aluminium aluminium Foil Co., Ltd)；
The hot sealing layer 5, which is selected, easily takes off film with a thickness of 30 μm of conventional curtain coating co-extrusion PE；
Outer adhesive layer 2, interior adhesive layer 4 select solvent borne polyurethane glue, and (trade mark LH-3721, manufacturer are Jiangsu Li He adhesive Co., Ltd).
The production technology of the plastic-aluminum epiphragma used for cosmetic of this comparative example is the same as comparative example 1.
The performance test of embodiment is as follows:
1) openable cover test method and evaluation: the hot sealing layer of cosmetics epiphragma and PP sheet material are sealed, heat-sealing pressure Power is 0.2MPa, and the heat-sealing time is 1s, and heat-seal equipment is that the HST-H3 of Labthink Instruments Co., Ltd. seals testing machine. 150 DEG C of temperature < when heat seal strength is greater than 3N/15mm are considered as OK, are considered as NG greater than 150 DEG C.
2) it resistance to oily stain test method and evaluation: selects a paste cosmetic applying in epiphragma superficies, wipes after ten minutes It goes cosmetics to observe outer layer state, there is cosmetics residual to be considered as OK, no cosmetics residual is considered as NG.
3) printing test method and evaluation: this test uses letterpress, in paper plastic-aluminum epiphragma finished product used for cosmetic Superficies are printed, and printing ink selects the UV161 series ink for Hang Hua ink limited liability company, after being completed for printing Ink adhesion test is carried out using GB/T7706-2008 " relief printing plate decoration printed matter ", is if oil-free Motuo falls test result OK, if having the ink test result that falls off is NG.
4) method for testing tightness and evaluation: using GB/T1038-2000 " plastic film and the test of thin slice gas-premeable Method pressure differential method ", as gas transit dose≤0.5cm3/ ㎡ for 24 hours 0.1MPa when, leakproofness OK；When gas transit dose >= 0.5cm3/ ㎡ for 24 hours 0.1MPa when, leakproofness NG.
Using following test method easily taking off to plastic-aluminum epiphragma used for cosmetic prepared by embodiment 1-3 and comparative example 1-2 Gai Xing, resistance to oily stain, printing, leakproofness are tested, and test result is listed in table 1:
Table 1
Embodiment 1 Embodiment 2 Embodiment 3 Comparative example 1 Comparative example 2
Openable cover OK OK OK NG NG
Resistance to oily stain OK OK OK NG OK
Printing OK OK OK OK NG
Leakproofness OK OK OK OK OK
It can be seen from the experimental result of table 1 plastic-aluminum epiphragma used for cosmetic provided by the invention not only have it is good easily Lid and leakproofness are taken off, relative to traditional paper as outer layer, resistance to oily stain can be more excellent, and has the preferable of traditional paper Printing；For hot sealing layer using easily taking off PE film, easily taking off EMA film or easily take off eva film etc. and easily take off film, processing temperature is lower, And product heat seal strength is controllable.
Presently preferred embodiments of the present invention is illustrated above, but the present invention is not limited in the implementation Example, those skilled in the art can also make various equivalent changes on the premise of not violating the inventive spirit of the present invention Type or replacement, these equivalent modifications or replacement are all included in the scope defined by the claims of the present application.
