A kind of good toughness and low temperature resistant CPP, the CPP substrate layers are made up of the component of following parts by weight：PP resins 105 parts, 10 parts of surfactant, 32 parts of antistatic master batch；The PP layers of component by following parts by weight is constituted：PP resins 95 Part, 25 parts of polymer micro-emulsion, 6 parts of slipping agent；The nexine is made up of the component of following parts by weight：95 parts of PP resins, POE 22 parts of toughener is compounded with POP.
A kind of good toughness and low temperature resistant CPP, the polymer micro-emulsion are made up of the component of following parts by weight：Breast 35-45 parts of agent, 65-75 parts of water, 15-26 parts of crosslinking functionality monomer, 25-35 parts of aqueous initiator.
The production technology of a kind of good toughness and low temperature resistant CPP, comprises the following steps：
(1) heated after adding antistatic master batch in every cubic metre of CPP substrate layers, polymer is smeared on PP layers Heated, heated after POE and POP compounding toughener is smeared on nexine after microemulsion；
(2) sided corona treatment is carried out by above-mentioned three layers, the sided corona treatment uses online dual station formula sided corona treatment；
(3) film is wound, so that CPP films are made；
(4) it is made after CPP films, is packed using packaging bag or carton.
Heating-up temperature is 40-50 DEG C in a kind of good toughness and low temperature resistant CPP, the step (1).
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of good toughness of the invention and low temperature resistant CPP films and preparation method thereof, polymer emulsion of the invention enters one Step improves the optical clarity of the CPP films obtained by the present invention；
2nd, a kind of good toughness of the invention and low temperature resistant CPP films and preparation method thereof, the present invention effectively overcome CPP films The shortcoming of embrittlement easy at low temperature, the lower temperature resistance of obtained CPP films is good；
3rd, a kind of good toughness of the invention and low temperature resistant CPP films and preparation method thereof, preparation method of the invention are simple, and And the toughness of obtained CPP films is also preferable.
Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, with reference to embodiment, to present invention work Further to describe in detail, exemplary embodiment and its explanation of the invention is only used for explaining the present invention, is not intended as to this The restriction of invention.
10 parts of surfactant, 32 parts of antistatic master batch；The PP layers of component by following parts by weight is constituted：PP resins 95 parts, 25 parts of polymer micro-emulsion, 6 parts of slipping agent；The nexine is made up of the component of following parts by weight：95 parts of PP resins, POE and POP 22 parts of toughener of compounding
Embodiment 1
The performance such as table 1 obtained according to embodiment 1-6：
