Embodiment 1

[0029]The present invention provides a technical solution: a sanitary napkin for silk soft printing small envelope preparation process, the production process includes the following steps:

[0030]S1: Material Selection: Polyethylene 55%; antibacterial pellets 2%; antioxidant 0.1%; PE hole membrane penetration 4%; polyolefin-based copolymer resin composition 30%; thermoplastic elastomer particles 4%; soft function 6% of sexual pages; polyethylene in S1 is a metallocene linear polyethylene.

[0031]S2: Material blend: Pour the selected material into the mixer, stir mix, mix between the original, the mixture is a vertical mixer, and the mixing machine is 200R / min, The stirring time was 15 minutes.

[0032]S3: Shear kissant: Pour the material uniform in S2 into the mixer, the mixer produces a large shear force, cut the material high-speed shear, so that the material is fast in the kneaders Flow, accelerate the kneading process, forming a high temperature fluid after shearing kneading, the tem...

Embodiment 2

[0040]Based on the first example, the present invention provides a technical solution: a sanitary napkin for silk soft printing small package film preparation processes, and the production process includes the following steps:

[0041]S1: Material Selection: Polyethylene 60%; 3% of antibacterial pellets; antioxidants 0.15%; PE punch membrane penetrant 4.2%; polyolefin-based copolymer resin composition 35%; thermoplastic elastomer particles 6%; Soft function 8% of sexual pellets; polyethylene in S1 is a metallocene linear polyethylene.

[0042]S2: Material Common: Pour the selected material into the mixer, stir mix, mix between the original, the mixture is a vertical mixer, and the mixing machine is 220 r / min, The stirring time was 18 minutes.

[0043]S3: Shear kissant: Pour the material uniform in S2 into the mixer, the mixer produces a large shear force, cut the material high-speed shear, so that the material is fast in the kneaders Flow, accelerate the kneading process, forming a high te...

Embodiment 3

[0051]The present invention provides a technical solution: a sanitary napkin for silk soft printing small envelope preparation process, the production process includes the following steps:

[0052]S1: Material Selection: Polyethylene 70%; 5% of antibacterial parenchula; antioxidant 0.2%; PE hole membrane penetrant 4%; polyolefin-based copolymer resin composition 40%; thermoplastic elastomer particles; soft function 8% of sexual diet; polyethylene is a metallocene linear polyethylene.

[0053]S2: Material blend: Pour the selected material into the mixer, stir mix, mix between the original, the mixture is a vertical mixer, and the mixing machine is 200R / min, The stirring time was 15 minutes.

[0054]S3: Shear kissant: Pour the material uniform in S2 into the mixer, the mixer produces a large shear force, cut the material high-speed shear, so that the material is fast in the kneaders Flow, accelerate the mixing process, forming a high temperature fluid after shearing kneading, the temperature...

Abstract

The invention discloses a preparation process of a silky soft printing small coating film for sanitary napkins. The preparation process comprises the following steps of material selection, material blending, shearing and mixing, melt extrusion, chilling and sheet casting, online thickness measurement, corona surface roughening treatment, rolling and slitting. Flexible modified master batches are developed together with material suppliers, the flexible modified master batches, metallocene linear polyethylene (PE), thermoplastic elastomer particles and the like are put according to a specific ratio, the softness of a base material film is improved, by adopting a large tap casting rubber roller with an excellent cooling effect and high-mesh-number carborundum,meanwhile, a shallow pear grain pressing technology is selected, the embossing on the surface of the film is fine and smooth, adhesion of a printing ink layer is facilitated, the problem that the printing effect is affected due to slipping of the film surface is solved, the problem that the printing effect is affected due to hard hand feeling and deep embossing of a PE film produced by a traditional large tape casting rubber roller is solved, and the quality of an extruded product can be improved by utilizing an automatic die head technology.

Description

Technical field[0001]The present invention belongs to the field of sanitary napkin packaging, and in particular, a sanitary napkin is used as a silk soft printing small envelope preparation process.Background technique[0002]The sanitary napkin is a substance with an absorption, the main material is a high molecular polymer and a polymer polymer composite paper formed by cotton, non-woven, pulp or above, and the side of the side is mainly used to prevent side leakage. Because the use of time and the sanitary cotton body present a certain angle, it is easier to rub the mice, so the sanitary napkins on the side of the soft material are favored by women.[0003]The envelope is a film of a monolithic sanitary napkin, which is a monolithic sanitary napkin product, which is divided into PE envelope, non-woven envelope, composite nonwoven fabric, aluminum foil film, PE film is structure The simplest polymer organic compound, the most widely widely used polymer material in today's world, the P...
