Advantages and disadvantages of paper packaging(1)

Paper packaging materials have characteristics such as environmental protection, re-cycling and cost saving. With the increasing demand for environmental protection of packaging materials throughout the international market, paper packaging materials are packaging materials. Paper packaging materials have another characteristic in addition to environmental protection, which is that they can quickly pass through the commercial customs to achieve the purpose of fast logistics and cost saving. Now to understand the advantages of paper packaging materials and the performance of packaging materials used as food packaging.

Advantages of paper packaging materials.

Due to the above characteristics of paper packaging materials, paper packaging materials are increasingly used, paper packaging materials are the reason for the dominance of the packaging field, in addition to the above characteristics, but also has the following unique advantages.

First, a wide range of raw materials, low cost, a variety of varieties, easy to form mass production;

Second, good processing performance, easy to composite processing and excellent printing performance;

Third, has a certain mechanical parts can, light weight, good buffer parts;

Four, good health and safety;

Five, the waste can be recycled, no white pollution.

Performance of paper packaging materials.

Paper as modern packaging materials are mainly used to make cartons, paper boxes, paper bags, paper containers and other packaging products, including corrugated cardboard and its cartons occupy a dominant position in paper packaging materials and products; composite paper and cardboard made from a variety of materials, special processing paper has been widely used, and will partially replace the application of plastic packaging materials in food packaging to solve the environmental protection problems caused by plastic packaging.

Used as food packaging paper packaging materials, its performance is mainly reflected in the following aspects.

A, printing performance

Paper and cardboard absorption and bonding ink ability is strong, good printing performance, therefore, commonly used in packaging for printing surface. Paper and cardboard printing performance is mainly determined by the surface smoothness, sizing skin, elasticity and bonding force.

B, health and safety performance

In the processing of paper, especially chemical pulp, usually residual certain chemical substances (such as sulfate pulp process residual lye and salts), so must be based on the contents of the packaging to correctly and reasonably choose a variety of paper and paperboard.

C, the barrier performance

Paper and paperboard are porous fibre materials, moisture, gas, light, grease and other degrees of permeability, and its barrier properties by the temperature and humidity of the impact of the larger. A single paper packaging materials generally can not be used for packaging moisture, high oil content and high barrier requirements of food, but can be appropriate surface processing to meet the requirements of its barrier properties.
