When film internal layer participate in heat seal process.It is found by the applicant that needing to control in antistatic film provided by the invention
The ratio of three layer weight parts, it is desirable that prevent internal layer content therein from very few, otherwise can reduce heat seal strength and the influence of film
The performances such as the pressure maintaining of film.And high density polyethylene (HDPE) as film middle layer and outer layer cannot be used in film internal layer, it needs
The linear low density polyethylene with proper flow and density is used, it is former to facilitate film internal layer in heat seal process in this way
Between material can be melt bonded under relatively lower temp, and can be quickly cooled down solidification, the gas in block film, Er Qieqi
Leakproofness and pressure holding effect are obviously improved, the handling characteristics suitable for buffering package.
Antistatic film in the present invention has the originals such as specific high-density polyethylene, linear low density polyethylene, antistatic agent
Material is prepared, and is three-decker, and extruding of the antistatic agent of thin film exterior layer by inner part subchain gradually moves to film table
Face.The hydrophilic radical exposure of antistatic agent absorbs the moisture in air in air, forms water film in film surface gradually
The charge of release film surface accumulation is to play antistatic property.Antistatic agent carrier used is no more than in the present invention for density
0.90g/cm3Low-density LLDPE, the density of antistatic agent is 0.85g/cm3, outer layer and middle layer use density to be higher than 0.95g/
cm3High density HDPE.Wherein HDPE density used in middle layer is higher than the density of outer layer HDPE, and antistatic agent and its carrier are in outer layer
Gradually to external migration under the extruding of high density HDPE molecule, antistatic film is formed in film surface.And because middle layer is using more
Highdensity HDPE forms one of barrier wall to antistatic agent and its carrier, and antistatic agent and its carrier can only outside layer surfaces
Migration, and cannot be migrated to middle layer or internal layer.
It is found by the applicant that helping to improve the antistatic effect of film by the setting of above-mentioned density gradient, effectively reduce
The resistance value of film, and the unexpected discovery of applicant cooperates by above-mentioned setting, then with components such as certain openings agent, it can
So that the antistatic effect of film is kept for a long time, in addition can the resistance value of film over time further gradually drop
Low, the antistatic effect of film is become better and better.However, the density of each raw material to be not simply arranged to the density of antistatic agent
Less than the density of outer layer raw material, the density that the density of outer layer raw material is less than middle layer raw material can reach said effect, when antistatic
The density of agent is too small, or the density contrast between outer hdpe layer away from it is too big when be easy to cause antistatic agent and high
Less efficient dispersal between density polyethylene, antistatic agent are easy to reunite, and cause the antistatic property of film bad, or even due to
Material dispersion mixing is uneven, causes to form stress concentration point inside film, could not improve antistatic effect, influences instead thin
The mechanical performances such as the tensile strength of film.And it also will affect material when gap is excessive between middle layer material density and outer layer material density
In behaviors such as melting, flowings, film bubble is easy to swing during by raw material extrusion-blown modling or even raw material cannot blow out film bubble etc.
Problem influences the smooth machine-shaping of product.
