The invention discloses a low-temperature heat-sealing package film and a preparation method thereof. The heat-sealing package film includes an A layer, a B layer and a C layer, wherein the A layer is a low-temperature heat-sealing layer, the B layer is a core layer and the C layer is a printing layer. The A layer includes 40-45% of a polyester aluminum-plated film, 47-50% of polypropylene resin and 3-5% of a VM3980 thermoplastic elastomer; the B layer includes 97-99% of polypropylene and 1-3% of an anti-static smooth master batch; and the C layer includes 96-98% of polypropylene and 2-4% of an anti-adhesion agent. The preparation method includes the following steps: material blending, melt extrusion, sheet casting, longitudinal stretch, transversal stretch, drawing and trimming, rolling-up, cutting and production of the finish product. The package film reduces solvent pollution due to thin film printing and pre-coating treatment, is reduced in processing cost, and is reduced in cost and is environment-friendly. The method reduces the initial heat-sealing temperature of the heat-sealing package film and increases sealing strength of the package film product.

B layer: 97%-99% polypropylene, 1%-3% antistatic smooth master batch;
C layer: the anti-anti-adhesive agent of 96%-98% polypropylene, 2%-4%.
The each layer thickness profile of described A, B, C: Low Temperature Thermal sealing A is 0.8-5 microns, and sandwich layer B is 7-40 microns, and printed layers C is 1-3 microns.
Described low-temperature heat-sealing packaging film thickness is 10-45 microns.
The preparation method of described low-temperature heat-sealing packaging film, comprise the following steps: comprise the following steps: batch mixing, melt extrude, slab, longitudinal stretching, cross directional stretch, traction trimming, rolling, cut, finished product, it is characterized in that: described in melt extrude middle extrusion temperature and be 190-260 DEG C, die head temperature is 230-255 DEG C; In described slab process, chilling roller and tank temperature are 25-50 DEG C; In described longitudinal stretching process, longitudinal preheat temperature is 116-145 DEG C, and longitudinal drawing temperature is 120-135 DEG C, and longitudinal setting temperature is 128-145 DEG C, and longitudinal stretching ratio is 4-6 times; In described cross directional stretch process, horizontal preheat temperature is 160-175 DEG C, and transverse drawing temperature is 150-168 DEG C, and horizontal setting temperature is 160-170 DEG C, and cross directional stretch ratio is 7-10 times.
Beneficial effect of the present invention:
1, by adding VM3980 thermoplastic elastomer, the initial heat-sealing temperature of heat-sealing material is reduced;
2, Low Temperature Thermal sealer of the present invention is at 85 degree of-95 degree and heat sealable;
3, during sealing, heating-up temperature reduces, and is conducive to energy-conservation;
4, because seal under low-temperature condition, Low Temperature Thermal sealer because of heat distortion, can not improve Low Temperature Thermal sealer product quality.
