Hydrophobic grouping and hydrophilic radical are had in the molecular structure of activating agent, under the action of hydrophilic radical, the surface of film will form parent
Water surface, so as to increase the wetting tension of film surface；
Simultaneously when water is contacted with film surface, part of the surface activating agent is dissolved in water, and reduces the surface tension of water, to subtract
Few and film surface contact angle reaches so that water leaves in film surface wetting and spreading at the moisture film of a continuous uniform, and along film surface
Anti- fog effect, and then the anti-fog properties of film can be increased, to guarantee the transparency of film.
Further, it is provided with several antifog microcapsules in the hot sealing layer, is provided with cavity in the antifog microcapsules,
Antifoggant is provided in the cavity.
By using above-mentioned technical proposal, the antifoggant in antifog microcapsules can constantly diffuse to the surface supplement, from
And it is able to extend the antifog duration for easily taking off film.
Further, several antifog microcapsules are again provided in the sandwich layer.
By using above-mentioned technical proposal, antifog microcapsules are equally set in sandwich layer, can further extend and easily take off film
The antifog duration.
Further, the 10-15% with a thickness of overall thickness of the hot sealing layer, the 64- with a thickness of overall thickness of the sandwich layer
75%, the 15-20% with a thickness of overall thickness of the corona layer, the 1-5% with a thickness of overall thickness of the anti-fog layer.
By using above-mentioned technical proposal, hot sealing layer with a thickness of 10-15% when, film have it is excellent easily take off performance, too
It is thin, it is easy to run through in heat seal process, too thick, film is then not easy to open；Sandwich layer with a thickness of 64-75% when, film have it is excellent
Toughness and translucency, too thin, the toughness of film can reduce, too thick, and the translucency of film can reduce；Corona layer with a thickness of 15-
20%, and anti-fog layer with a thickness of 1-5%, film has excellent anti-fog effect.
Further, the overall thickness of the hot sealing layer, sandwich layer, corona layer and anti-fog layer is 50-80 μm.
By using above-mentioned technical proposal, overall thickness is 50-80 μm, leakproofness, easy the taking off property and anti-that can guarantee film
Mist, while can reduce production cost.
Further, the hot sealing layer is provided with embossing far from the side of sandwich layer.
By using above-mentioned technical proposal, on the one hand embossing is capable of increasing the wetting tension of film surface, so as to increase
Film it is anti-fog properties；On the other hand the frictional force that can increase heat-sealing layer surface, to conveniently open film.
Further, the hot sealing layer is the mixed layer for easily taking off modified polypropene and antifog modified polypropene.
Film can be increased using easily modified polypropene and antifog modified polypropene is taken off by using above-mentioned technical proposal
Easily take off performance and anti-fog properties.
Further, the sandwich layer is the mixed layer of copolymer polypropylene and antifog modified polypropene.
By using above-mentioned technical proposal, antifog modified polypropene is contained in sandwich layer, the anti-fog properties of film can be increased.
In conclusion the utility model has the following beneficial effects:
1, corona layer and anti-fog layer are used, so that the anti-fog properties effect of film can be increased by generating；
2, antifog microcapsules are used, to generate the effect for being able to extend the film antifog duration；
3, embossing is used, so that film easily taking off property and anti-fog properties effect can be increased by generating.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
Embodiment:
It is a kind of to increase anti-fog properties film, referring to Fig.1 comprising corona layer 1, be disposed in corona layer 1 sandwich layer 2,
Hot sealing layer 3 and anti-fog layer 4.
Referring to Fig.1, the overall thickness of anti-fog layer 4, hot sealing layer 3, sandwich layer 2 and corona layer 1 is 50-80 μm；Wherein hot sealing layer 3
With a thickness of the 10-15% of overall thickness, the 64-75% with a thickness of overall thickness of sandwich layer 2, the 15- with a thickness of overall thickness of corona layer 1
20%, the 1-5% with a thickness of overall thickness of anti-fog layer 4.
Referring to Fig.1, hot sealing layer 3, which is selected, easily takes off modified polypropene and antifog modified polypropene blended material, wherein antifog change
Property pp material accounting be 3-8%；Sandwich layer 2 selects homopolypropylene, and perhaps copolymer polypropylene raw material or its blend add again
Add antifog modified polypropene；The present embodiment center core layer 2 selects copolymer polypropylene and antifog modified polypropene, wherein antifog modification is poly-
Propylene accounting 3-6%.
Referring to Fig.1, corona layer 1 selects copolymer polypropylene raw material；Anti-fog layer 4 is by the antifoggant coated in 3 surface of hot sealing layer
It is formed, antifoggant generally all selects surfactant, mainly uses organic silicon rubber or Organic fluoride macromolecule；Organosilicon and
Organic fluoride has very low surface energy, therefore hydrone is difficult to be condensed into water droplet on organosilicon and Organic fluoride, to play anti-
The effect of mist.
Referring to Fig.1, antifog microcapsules 5 are provided in hot sealing layer 3 and sandwich layer 2, antifog microcapsules 5 are evenly distributed on heat-sealing
In layer 3 and sandwich layer 2；Theoretically, the additive amount of antifog microcapsules 5 is The more the better, but by technique and material body etc. because
The limitation of element, the additive amount of antifog microcapsules 5 cannot be too many.
Referring to Fig. 2, it is provided with cavity 51 in antifog microcapsules 5, is provided with antifoggant in cavity 51；In antifog microcapsules 5
Antifoggant select polyol fatty acid rouge, quaternary ammonium salt surface active agent, polyalcohol polyoxyethylene ether etc..
Working principle is as follows:
Hot sealing layer 3 and anti-fog layer 4 are capable of increasing the wetting tension of film surface；Work as water simultaneously to contact with film surface, part table
Face activating agent is dissolved in water, and reduces the surface tension of water, so that the surface contact angle with film is reduced, so that water moistens in film surface
Wet-laying transforms into the moisture film of a continuous uniform, and leaves along film surface, reaches anti-fog effect, and then can increase the anti-fog properties of film,
To guarantee the transparency of film.
