Composite paper for fruit bagging

Abstract

The invention discloses composite paper for fruit bagging. The composite paper for fruit bagging is characterized in that polyethylene and polypropylene are used as polymer raw materials, calcium carbonate powder is used as a main inorganic mineral substance, and dolomite dust, kaolin, montmorillonoid and bentonite are added; the inorganic mineral substances can be well combined with the calcium carbonate powder and have a certain lubrication action, so that the chemical property of the composite paper is more stable, and the hardness of the composite paper can also be improved to a certain extent; nanometer titania and white carbon black can improve the hardness of the composite paper to a certain degree so that the composite paper cannot be too soft and the capacity of resisting compression of objects of the composite paper can be improved, and meanwhile, the nanometer titania can serve as a dispersing agent to a certain degree to make materials more soluble in one another and make the materials better react; titanium dioxide is selected as a brightening agent and has a good brightening effect so that the whiteness degree of the composite paper can be close to that of ordinary paper, and selected antibacterial agent has high antibacterial effect and also makes the composite paper have good air permeability.

Description

technical field [0001] The invention relates to a composite paper, in particular to a composite paper used for fruit and vegetable bagging. Background technique [0002] Composite paper is also called stone paper. It is made of limestone mineral resources as the main raw material and polymer as auxiliary material. It uses the chemical principle of polymer interface and the characteristics of polymer modification. After special processing, it is extruded by polymer. , Made by blow molding process. It has the advantages of simple production process, high output, low energy consumption, no use of plant fibers, no felling of trees, which can save a lot of wood and protect the natural ecology, so it has received widespread attention. Nowadays, composite paper is often used to replace traditional paper and plastic, and has achieved good social benefits. [0003] Whenever the fruits and vegetables are ripe, the uncle of the farmer will bag the fruits and vegetables to prevent the...

AI Technical Summary

Problems solved by technology

Due to the characteristics of composite paper, it is often made into bags to protect fruits and vegetables. However, the traditional composite paper has poor air permeability. After the internal oxygen is exhausted, the fruits and vegetables can only carry out anaerobic exercise, which will easily cause the fruits and vegetables to rot or die

At the same time, the traditional composite paper does not have the antibacterial function, so bacteria will still enter the bag, resulting in the death of fruits and vegetables
