Embodiment 1

[0140] (1) Preparation of special material for aluminized cast polypropylene film

[0141] First dry compound the main antioxidant, secondary antioxidant, halogen absorber, reinforcing agent, barrier agent and anti-adhesive agent to obtain compounding aids, and then compound the compounding aids with ethylene-propylene random copolymer Melting and blending, and then sending it into an extruder for co-rotating twin-screw extrusion and granulation to obtain a special material for aluminum-coated cast polypropylene film.

[0142] The conditions of melt blending include: the blending temperature is 45°C, the blending time is 3min, operated under a nitrogen blanket, N 2 The pressure is 0.15MPa;

[0143] The conditions for extrusion granulation include: the granulation temperature is 210° C., the cutting water temperature is 63° C., and the screw speed is 180 rpm.

[0144] Wherein, based on 100 parts by weight of the ethylene-propylene random copolymer, see Table 1 for each raw ma...

Embodiment 2-10

[0148] According to each step of Example 1, the aluminum-coated cast polypropylene film special material and the aluminum-coated cast polypropylene film were respectively prepared. The difference is the raw materials and dosage in the compounding auxiliary agent, see Table 1 for details.

[0149] Raw materials and consumption of compounding auxiliary agent in each embodiment of table 1

[0150]

Embodiment 11

[0152] According to the method of Example 1, the difference is that "1 part by weight of C601" is replaced by "2 parts by weight of C601".

Abstract

The invention relates to the field of polypropylene casting packaging films, and discloses a polypropylene resin composition, a special material for an aluminum-plated casting polypropylene film, the aluminum-plated casting polypropylene film as well as a preparation method and application of the aluminum-plated casting polypropylene film. The polypropylene resin composition comprises an ethylene-propylene random copolymer and a compound auxiliary agent, wherein the compound auxiliary agent comprises a main antioxidant, an auxiliary antioxidant, a halogen absorbent, an anti-sticking agent, a reinforcing agent and a blocking agent. The corona attenuation retention and the aluminizing adhesive force of the aluminizing casting polypropylene film prepared from the composition are obviously improved, and the aluminizing casting polypropylene film is good in transparency and good in mechanical property.

Description

technical field [0001] The invention relates to the technical field of polypropylene cast packaging film, in particular to a polypropylene resin composition, a special material for aluminized cast polypropylene film, an aluminized cast polypropylene film and a preparation method and application thereof. Background technique [0002] Cast polypropylene film (CPP) is a non-stretched, non-oriented flat film. It has light weight, excellent transparency, good heat sealability, uniform thickness, excellent moisture resistance, oil resistance, high temperature resistance, scratch resistance and good applicability to packaging machinery. It is widely used in clothing, daily Packaging for cosmetics, food, industrial products, etc. Compared with biaxially oriented polypropylene film, cast polypropylene film has the advantages of simple processing equipment and low cost, and its scratch resistance and packaging machinery adaptability are better than polyethylene film, which is more su...
