Embodiment 1

[0022] Take non-toxic polypropylene and calcium carbonate degradable masterbatch with a weight ratio of 72:28 and evenly mix them. After conventional hot-melt, drawing, and weaving into woven fabric 1, the weight of woven fabric 1 is 72g / m 3 ; In addition, the non-toxic polyethylene and calcium carbonate degradation masterbatch with a weight ratio of 70:30 are evenly mixed, heated to become a liquid, and then the liquid is evenly poured on the base woven cloth 1 by a general coating method to form a high Molecular film 2, surface 2 of polymer film and synthetic paper 3 are rolled and heat-bonded to form the final product.

[0023] The model using non-toxic polypropylene is F401 (Yangzi Petrochemical Co., Ltd.), the particle size is 4.5mm, and the density is 0.93g / cm 3 , the melt index is 2.5~3.5g / 10min; the calcium carbonate degradation masterbatch model is MEF0690CB (Guangxi Luxin Environmental Protection Technology Co., Ltd.), the particle size is 2.5mm, and the density is 1...

Embodiment 2

[0025] Take non-toxic polypropylene and calcium carbonate degradable masterbatch with a weight ratio of 85:15 and mix them evenly. After conventional hot-melt, wire drawing, and weaving into woven fabric 1, the weight of woven fabric 1 is 70g / m 3 In addition, the non-toxic polyethylene and calcium carbonate degradation masterbatch with a weight ratio of 85:15 are evenly mixed, heated to become a liquid, and then the liquid is evenly poured on the base woven cloth 1 by a general-purpose coating method to form a polymer Film 2, the polymer film 2 side and the synthetic paper 3 treatment side are rolled and heat-bonded to form the final product.

[0026] The model of non-toxic polypropylene is T305, the particle size is 4.5mm, and the density is 0.93g / cm 3 , the melt index is 2.5~3.5g / 10min; the calcium carbonate degradation masterbatch model is MEF0690CB, the particle size is 2.5mm, and the density is 1g / cm 3 , the melt index is 0.7g / 10min, and the degradation induction period ...

Embodiment 3

[0028] Take non-toxic polypropylene and calcium carbonate degradable masterbatch with a weight ratio of 80:20 and mix them evenly. After conventional hot-melt, drawing, and weaving into woven fabric 1, the weight of woven fabric 1 is 60g / m 3 , then take the non-toxic polyethylene and calcium carbonate degradation masterbatch with a weight ratio of 82:18 and the non-toxic polyethylene dark-colored light-proof masterbatch accounting for 3% of the total weight of the non-toxic polyethylene and calcium carbonate degradation masterbatch, mix evenly, and heat It turns into a liquid, and then the liquid is uniformly and hotly poured on the base woven fabric 1 to form a polymer film 2 by using a general film coating method, and the polymer film 2 surface is rolled and heat-bonded with the synthetic paper 3 treatment surface to form the final product. The polymer film thickness is 0.07mm.

[0029] The model using non-toxic polypropylene is T300 (Shanghai Petrochemical Co., Ltd.), the p...

Abstract

The invention discloses a full-degradable salt large packing material with high quality printing effect. The salt large packing material comprises woven cloth and is characterized in that the woven cloth is taken as the basal body and provided with a polymer film, and the surface of the polymer film and synthetic paper are rolled in a heat sealing manner; the woven cloth comprises non-toxic polypropylene and calcium carbonate degradation master batch, and the weight ratio of the non-toxic polypropylene and the calcium carbonate degradation master batch is (70-85): (15-30); the polymer film comprises non-toxic polyethylene and calcium carbonate degradation master batch, and the weight ratio of the non-toxic polyethylene and the calcium carbonate degradation master batch is 70-85:15-30. Thesalt large packing material has the characteristics of strong tensile property, sealing property, photophobism, easy printing and high refinement; the rejected material of the packing material can bequickly and fully degraded in the natural environment; the requirements of environmental protection can be met; and the characteristics of the packing material particularly meets the requirements of large packing for the salt above 20 kilograms, can be loaded, is waterproof and can prevent the iodine ions in the salt from volatilizing, has artistic appearance and good durability, and is suitable for repeated handling and super-high stacking.

Description

technical field [0001] The present invention relates to a kind of packaging material, specifically, a kind of high-grade packaging material which is especially suitable for the demand of large-scale packaging of salt prepared by taking biodegradable composite material as raw material and combining the advantages and characteristics of polypropylene woven cloth, polyethylene polymer film and synthetic paper. A fully degradable large salt packaging material with high-quality printing effect, and the invention also relates to a preparation method of the packaging material. Background technique [0002] At present, my country uses 450 million large salt packaging bags every year, all of which are non-degradable plastic packaging materials. The waste of packaging materials pervades the whole society. Where there are people, salt is used, and there will be salt packaging waste. Therefore, it is extremely harmful to environmental protection and seriously affects the requirements f...
