Description

A kind of preparation method of waterproof barrier material
Technical field
The present invention relates to packaging material preparing technical field, and in particular to a kind of preparation method of waterproof barrier material.
Background technology
Packaging material is widely used in the fields such as packing container, packing and decorating, packages printing, packed and transported, it is for work Industry production, people's daily life play an important roll.With the industrialized continuous development in China, the species of industrial products and production The raising year by year of amount, the Year's consumption of packaging material is also increasing, thus, Chinese society to the demand of packaging material drastically Rise.
Traditional packaging material is usually using polyethylene, polypropylene as primary raw material, cheap, the system of these packaging materials It is standby more convenient, but since these packaging materials are difficult degraded, serious problem of environmental pollution can be caused after abandoning.In recent years Come, with the rapid development of packing technique, the continuous enhancing of people's environmental consciousness, environmental type packaging material is increasingly subject to Favor.With the development of plant fiber packing material technology of preparing, nondegradable plastics based packaging material will be greatly reduced Usage quantity, alleviates the serious realistic situation of white pollution.
But plant fiber packing material there is also some problems in process of production at present:Many plants are less susceptible to Processing, and particle is larger, and material is easily uneven after making packaging material, therefore can produce various protrusions, causes to pack Material appearance is unsightly;Some packaging materials cause to hold food etc. being easy to mouldy change due to the effect of no bacteriostasis antibiosis Matter;Resistance to elevated temperatures is generally poor;Water proofing property is also poor etc..In addition, the compressive property of existing packaging material is generally all poor, Easily it is damaged when being hit, so as to be difficult to realize the good protection to packing product.
It would therefore be highly desirable to there is a kind of environmentally friendly, uniform in material, antibacterial bacteriostatic and the packaging material that can be degraded.
