Embodiment 1

[0020] Add the main materials in each layer of A, B, C, and D to the extruder respectively, and then add the auxiliary materials in each layer of A, B, C, and D after the main materials in each layer are melted Melt in the extruder, then extrude the molten material of the main material and auxiliary material onto the casting roll, and then pass through the cooling roll for cooling treatment, and finally the layers of A, B, C, and D are combined to form the matte satin film , and corona treatment is carried out on both sides of the matte satin film; the melt processing temperature in the extruder and the die head processing temperature are both 215°C; the temperature of the casting roll is 28°C, and the cooling The temperature of the rolls was 35°C.

[0021] The A layer includes 44wt% homopolypropylene, 44wt% high density polyethylene, and 9wt% block copolymerized polypropylene resin, and the B and C layers both include 49wt% homopolypropylene, 44wt% high Density polyethylene,...

Embodiment 2

[0023] This embodiment is identical with embodiment 1 process, only process parameter has been adjusted, specifically:

[0024] The A layer includes 46wt% homopolypropylene, 46wt% high density polyethylene, and 11wt% block copolymerized polypropylene resin, and the B and C layers both include 51wt% homopolypropylene, 46wt% high Density polyethylene, 2wt% spherical opening agent, and 4wt% nanoscale additives, the D layer includes 90wt% homopolypropylene, 15wt% polyolefin elastomer; the A layer, B layer, C The thickness ratio of layer and D layer is 61:16:16:11.

Embodiment 3

[0026] This embodiment is identical with embodiment 1 process, only process parameter has been adjusted, specifically:

[0027] The A layer includes 45wt% homopolypropylene, 45wt% high density polyethylene, and 10wt% block copolymerized polypropylene resin, and the B and C layers both include 50wt% homopolypropylene, 45wt% high Density polyethylene, 1.5wt% spherical opening agent, and 3.5wt% nanoscale additives, the D layer includes 88wt% homopolypropylene, 12wt% polyolefin elastomer; the A layer, B layer , C layer, D layer thickness ratio is 60:15:15:10.

[0028] The main performance parameters of the matting satin film produced according to the foregoing embodiments are shown in the table below:

[0029]

[0030] The above tensile strength parameters show that the film has good toughness and good tensile strength; the elongation at break parameter shows that the film has a good puncture resistance; the haze parameter shows that the film has low gloss, and the appearance ...

Abstract

The invention relates to a light extinction silk and satin film and a protection process thereof. The light extinction silk and satin film comprises a layer A, a layer B, a layer C and a layer D which are sequentially compounded. The layer A is prepared from 44 wt% to 46 wt% of homo-polypropylene, 44 wt% to 46 wt% of high density polyethylene and 9 wt% to 11 wt% of block co-polypropylene resin, and the layer B and the layer C are both prepared from 49 wt% to 51 wt% of homo-polypropylene, 44 wt% to 46 wt% of high density polyethylene, 1 wt% to 2 wt% of spherical anti-block agent and 3 wt% to 4 wt% of nanoscale aid, and the layer D is prepared from 85 wt% to 90 wt% of homo-polypropylene and 10 wt% to 15 wt% of polytolefin elastomers. The thickness ratio of the layer A to the layer B to the layer C to the layer D is 60:15:15:10. During production, the main materials of all the layers are added into an extruder, after the main materials are melted, the auxiliary materials of all the layers are added into the extruder for fusion, then melt is extruded to a curtain coating roll, finally, all the layers are compounded into the light extinction silk and satin film, and the both sides of the light extinction silk and satin film are subjected to corona treatment. The light extinction silk and satin film is outstanding in moisture stopping performance, excellent in cold resisting performance, good in heat resisting performance, good in hand feeling and low in gloss, and gives people a noble visual feeling and the effect close to silks and satins.

Description

technical field [0001] The invention belongs to the technical field of film production, and in particular relates to a matte satin film and a production process thereof. Background technique [0002] With the development of economy and society, people have higher and higher requirements for packaging films. For example, traditional CPP films lack competitiveness in the market due to their barrier properties, hand feeling, etc., which directly affects CPP films. development of. Technologists urgently need to develop differentiated and high value-added CPP film products in order to meet the increasingly complex and changeable market demands. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a matte satin film and a production process thereof. [0004] In order to realize the purpose of the present invention, the present invention has adopted following technical scheme: [0005] A matte satin film, comprising ...
