Embodiment 1

[0008] Embodiment one: a kind of modified polyvinyl alcohol packaging material for clothing, its composition is polyvinyl alcohol, nanometer calcium carbonate, glyceryl stearate. Among these three components, the weight percentage of nano-calcium carbonate is 10%, the weight percentage of polyvinyl alcohol is 89.8%, and the weight percentage of stearic acid glyceride is 0.2%. Polyvinyl alcohol has a degree of polymerization of 1000 and a degree of alcoholysis of 98%.

[0009] The production method of the above-mentioned embodiment is as follows: after adding polyvinyl alcohol resin with a degree of polymerization of 1000 and a degree of alcoholysis of 98% into a kneading kettle, add an appropriate amount of water and stir, then add nano-calcium carbonate and stir, then add octadecanoic acid Glycerides are mixed to obtain a mixture, and then the mixture is processed into a packaging film for clothing by the salivation method or the blown film method.

Embodiment 2

[0010] Embodiment two: a kind of packaging material for clothing of modified polyvinyl alcohol, and its composition is polyvinyl alcohol, nanometer calcium carbonate, glycerin. Among these three components, the weight percentage of nano-calcium carbonate is 60%, the weight percentage of polyvinyl alcohol is 39.8%, and the weight percentage of glycerin is 0.2%. The degree of polymerization of polyvinyl alcohol is 2000, and the degree of alcoholysis is 99%.

[0011] The production method of the above-mentioned embodiment is: after adding polyvinyl alcohol resin with a degree of polymerization of 2000 and a degree of alcoholysis of 99% into a kneading kettle, add an appropriate amount of water and stir, then add nano-calcium carbonate and stir, then add glycerin, mix Finally, the mixture is obtained, and then processed into a packaging film for clothing by the salivation method or the blown film method.

Embodiment 3

[0012] Embodiment three: a kind of packaging material for modified polyvinyl alcohol clothing, its composition is polyvinyl alcohol, nano-calcium carbonate, glycerin, glyceryl stearate, among these four kinds of components, the weight of nano-calcium carbonate The percentage content is 5%, the weight percentage content of polyvinyl alcohol is 94.6%, the weight percentage content of glycerin is 0.2%, and the weight percentage content of glyceryl stearate is 0.2%. The degree of polymerization of polyvinyl alcohol is 1700, and the degree of alcoholysis is 99.98%.

[0013] The production method of the above-mentioned embodiment is as follows: after adding polyvinyl alcohol resin with a degree of polymerization of 1700 and a degree of alcoholysis of 99.98% into a kneading kettle, add an appropriate amount of water and stir, then add nano-calcium carbonate and stir, then add glycerin, ten Octacylglycerides are mixed to obtain a mixture, which is then processed into a packaging film ...

Abstract

A modified polyvinyl alcohol material for packing garment is prepared form polyvinyl alcohol, nanocalcium carbonate and processing assistants and its preparing process includes mixing and agitating above mentioned chemicals and assistants, then drooling or blowing for final product.

Description

technical field [0001] The invention relates to a packaging material and a production method thereof, in particular to a packaging material for nano-modified polyvinyl alcohol clothing and a production method thereof. Background technique [0002] Most of the existing clothing packaging films are polyethylene films, and the gloss and brightness of this polyethylene film are relatively low, and due to the effect of static electricity, dust is easily adsorbed on this film. Contents of the invention [0003] The purpose of the present invention is to develop a kind of nano-modified polyvinyl alcohol clothing packaging material and its production method for above-mentioned deficiency. [0004] The nano-modified polyvinyl alcohol packaging material for clothing of the present invention is composed of polyvinyl alcohol, nano-calcium carbonate, and processing aids, wherein the weight percentage of nano-calcium carbonate is 3%-80%, p...
