Description
Technical field
The present invention relates to a kind of preparation methods of the antibacterial ox-hide paper packing material of waterproof, belong to kraft paper bag technology of preparing neck
Domain.
Background technique
Packaging material is widely used in the fields such as packing container, packing and decorating, packages printing, packed and transported, for work
Industry production, people's daily life play a significant role.With the industrialized continuous development in China, the type and production of industrial products
The raising year by year of amount, the annual consumption of packaging material is also increasing, thus, Chinese society to the demand of packaging material sharply
Rise.It data show, the polybag after there is 80% use in China is finally transported to rubbish heap field area as conventional rubbish
Processing, only 7% plastics are recovered recycling, so needing using paper packaging bags.
Brown paper mainly uses kp softwood pulp for raw material, through being beaten, manufactures paper with pulp on fourdrinier machine.Usually
In yellowish-brown, half kraft pulp for floating or floating entirely is in filbert, cream-colored or white.Brown paper has intensity height, flexible solid,
Bursting strength is high, can bear larger pulling force and pressure does not rupture, be widely used in various package packing supplies, such as paper bag, handbag, coloured silk
Box, gift box etc..Due to meeting national environmental standard with nontoxic, tasteless, free of contamination characteristic, and it is degradable, recyclable
It recycles, has become the current of trend in environmental protection, brown paper has become one of packaging material most popular in the world.
In recent years, with food industry fast development, the requirement to product quality is higher and higher, and the health of brown paper,
Environmental protection provides wide market for it in food packaging.Although brown paper has good tearing toughness, it is thoroughly
Gas, moisture barrier property are bad, and the storage of the storage for product, especially food brings inconvenience, exist to limit brown paper
The application of food packaging applications.Simultaneously as the raw material of brown paper is natural fiber material, there are a possibility that rotten, mouldy,
There is potential threat to the sanitation performance of food.In addition, uncoated brown paper, rough surface, quality is loose, absorbency
By force, printing color is matt.In order to improve brown paper in the competitiveness of food packaging applications, especially to the improvement of brown paper performance
It is necessary.
Therefore it provides a kind of low production cost, the calendaring effect is good, has heat resistance, is unlikely to deform, oil resistant, waterproof
Effect is obvious, and the more environmentally friendly waterproof kraft paper of production process is of great significance.
