Embodiment 1

[0040] This embodiment discloses an antibacterial plastic packaging bag for diapers, comprising a plastic film layer 100 and an antibacterial nonwoven fabric layer 200, wherein the antibacterial nonwoven fabric layer 100 includes the following materials in parts by weight:

[0041]

[0042] 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.

Embodiment 2

[0044] This embodiment discloses the preparation method of the antibacterial plastic packaging bag for diapers in Example 1, in which the antibacterial non-woven fabric layer is bonded to the surface of the plastic film layer through acrylic resin;

[0045] The antibacterial nonwoven layer is prepared by the following steps:

[0046] Step 1, mix the fibers, polyvinyl alcohol fibers, oleic acid, chitosan and nanocellulose according to the mass parts to prepare master batches, and slice them for later use;

[0047] Step 2, the chips obtained in Step 1 are passed through a screw extruder 1 to obtain fibers;

[0048] The fiber obtained in step 3 and step 2 is drawn by air blowing, and the drafting airflow blows the fiber to the guide roller; the guide roller 31 and the drafting airflow clamp the fiber to move downward, and the fiber passes through a plurality of guide rollers to form a wave shape;

[0049] Step 4: The impact water flow impacts the wave-shaped fiber into the formi...

Abstract

The invention discloses a paper diaper antibacterial plastic packaging bag. The paper diaper antibacterial plastic packaging bag comprises a plastic film layer and an antibacterial non-woven fabric layer, and the antibacterial non-woven fabric layer is prepared from the following substances in parts 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. 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 in the length direction of the antibacterial non-woven fabric layer. The invention discloses a preparation method of the paper diaper plastic packaging bag. 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 a preparation method of an antibacterial plastic packaging bag for diapers. 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. Diapers can be regarded as an absorbent system, which is composed of multiple layers of materials bonded together. The main structure includes a surface covering layer, a lining non-woven thin cloth layer, a nylon film layer, a leak-proof bottom film, and leg openings to prevent side lea...
