Embodiment 1

[0041] This embodiment discloses an antibacterial plastic packaging bag for diapers, comprising a plastic film layer 100 and an antibacterial nonwoven layer 200, wherein the antibacterial nonwoven layer 200 includes the following materials in parts by weight:

[0042]

[0043]

[0044] The antibacterial non-woven fabric layer is provided with a stretchable structure along its length direction to cooperate with the deformation of the plastic film layer by external force.

[0045] In this embodiment, the antibacterial nonwoven layer is bonded on the surface of the plastic film layer by acrylic resin; wherein, the thickness of BOPP is 35 μm, the thickness of acrylic resin is 10 μm, and the thickness of the antibacterial nonwoven layer is 20 μm, wherein the nonwoven The protruding part of the V-shaped fiber protrudes into the acrylic resin layer 300 .

[0046] Antibacterial non-woven fabric is prepared through the following steps in the present embodiment:

[0047] Step 1, ...

Embodiment 2

[0065] The main difference between this embodiment and embodiment 1 is:

[0066] In the present embodiment, the antibacterial non-woven fabric layer 200 comprises the following materials in parts by weight:

Abstract

The invention discloses a paper diaper antibacterial plastic packaging bag, which comprises a plastic film layer and an antibacterial non-woven fabric layer, wherein the antibacterial non-woven fabric layer comprises the following substances by weight: 80-120 parts of polypropylene fiber, 15-30 parts of polyvinyl alcohol fiber, 5-15 parts of oleic acid, 10-20 parts of chitosan, and 5-10 parts of nano cellulose, and the antibacterial non-woven fabric layer is provided with a stretchable structure which is matched with the plastic film layer to deform under external force along the length direction of the antibacterial non-woven fabric layer. The invention discloses a preparation method of the paper diaper plastic packaging bag. According to the invention, through cooperation of the antibacterial lining non-woven thin cloth layer and the plastic film base layer, water and moisture are effectively prevented, and the structural stability and antibacterial property of the packaging bag are improved.

Description

technical field [0001] The invention relates to the technical field of production of diaper packaging bags, in particular to an antibacterial plastic packaging bag for diapers and a preparation method thereof. Background technique [0002] Plastic bags are indispensable items in people's daily life. They are often used to hold other items. They are widely used because of their cheapness, light weight, large capacity, and easy storage. Plastic bags are also often used to hold fruits and vegetables. Traditional plastic bags have poor antibacterial ability and are easy to breed bacteria. If they are used to hold fruits, vegetables and other items for a long time, they will easily accelerate their decay. [0003] In daily life, whether it is a supermarket or a family, they often stock up on diapers. The storage environment varies depending on the region or season. Providing an antibacterial plastic packaging bag for diapers that has strong antibacterial ability and is not easy t...
