Embodiment 1

[0035] A preparation method of an environment-friendly clothing packaging film, comprising the steps of:

[0036] Step 1: take by weighing 65Kg MDPE, 7Kg erucamide, 5Kg silicon dioxide and 1Kg antioxidant as the raw materials of the intermediate layer, take by weighing 75Kg EVA, 3Kg silicon dioxide and 11Kg HDPE as the raw materials of the surface layer one and surface layer two;

[0037] Step 2: adding the raw materials of the intermediate layer, surface layer 1 and surface layer 2 prepared in step 1 into three extruders for separate melting and mixing;

[0038] Step 3: Transport the melted raw materials from the three extruders to the same blow molding die for three-layer co-extrusion, and then cool, cut, and roll to obtain the finished environmentally friendly clothing packaging film.

[0039] Wherein, the total thickness of the packaging film is 0.5mm, and the thickness ratio of the first surface layer, the middle layer and the second surface layer is 1:2:1, and the thickn...

Embodiment 2

[0041] A preparation method of an environment-friendly clothing packaging film, comprising the steps of:

[0042] Step 1: take 70Kg MDPE, 9Kg erucamide, 7Kg silicon dioxide and 2Kg antioxidant as the raw materials of the intermediate layer, weigh 80Kg EVA, 5Kg silicon dioxide and 15Kg HDPE as the raw materials of the surface layer one and surface layer two;

[0043] Step 2: adding the raw materials of the intermediate layer, surface layer 1 and surface layer 2 prepared in step 1 into three extruders for separate melting and mixing;

[0044] Step 3: Transport the melted raw materials from the three extruders to the same blow molding die for three-layer co-extrusion, and then cool, cut, and roll to obtain the finished environmentally friendly clothing packaging film.

[0045] Wherein, the vacuum inside the blow molding head is 0.01-0.02Mpa, the particle size of silicon dioxide is less than 10um, and the antioxidant is a mixture of tea polyphenols and vitamin E, and the quality o...

Embodiment 3

[0047]A preparation method of an environment-friendly clothing packaging film, comprising the steps of:

[0048] Step 1: take by weighing 75Kg MDPE, 11Kg erucamide, 9Kg silicon dioxide and 3Kg antioxidant as the raw material of the intermediate layer, take by weighing 85Kg EVA, 7Kg silicon dioxide and 19Kg HDPE as the raw material of the surface layer one and surface layer two;

[0049] Step 2: adding the raw materials of the intermediate layer, surface layer 1 and surface layer 2 prepared in step 1 into three extruders for separate melting and mixing;

Abstract

The invention discloses an environment-friendly clothing packaging film, which relates to the field of packaging films. It mainly includes a surface layer 1, a middle layer and a surface layer 2 in sequence, and the raw material of the middle layer includes 65 to 75 parts of PE in parts by mass. , 7-11 parts of erucamide, 5-9 parts of silicon dioxide and 1-3 parts of antioxidant; the raw materials of the surface layer one and surface layer two all include 75-85 parts of EVA, 3-7 parts of dioxide Silicon and 11 to 19 parts of HDPE. By adopting the above technical scheme, EVA layers are respectively arranged on the two surfaces of the PE layer in the middle, so that when the erucamide in the PE layer migrates to the surface of the packaging film, it will be hindered by the EVA layer, so that the erucamide will not easily The surface of the packaging film forms powder. Therefore, when using this kind of packaging film to pack clothing or home textiles, it can effectively prevent the surface of clothing and home textiles from being contaminated with powder, thereby affecting sales.

Description

technical field [0001] The invention relates to the field of plastic packaging films, in particular to an environment-friendly clothing packaging film and a preparation method thereof. Background technique [0002] As people's living standards are getting higher and higher, people are paying more and more attention to basic necessities of life, especially clothing. In order to enable customers to have a better sense of expression, merchants often take out new clothes from the packaging film for customers to try on. [0003] In the prior art, the packaging films used for packaging clothing are generally made of PE materials. For example, the patent application document with the publication number CN109354783A discloses a polyethylene film and its preparation method. 15-2 parts of ethylene, 20-35 parts of linear low-density polyethylene, 30-70 parts of octene-ethylene polymer, 1-4 parts of slip agent, and 0.01-0.05 parts of defoamer are plasticized in the screw extruder Extr...
