It is not an exaggeration to call paper the "king of packaging materials". Paper is made from wood, and paper itself has a kind of fiber when it is manufactured. Therefore, paper will not be decomposed after being immersed in water. Therefore, from the perspective of packaging materials, paper and cardboard currently account for about 40% of all packaging materials on the market, of which paper accounts for about 22%, cardboard accounts for about 76%, and other materials account for about 2%. It can be seen that among paper materials, in addition to cardboard, paper is also widely used. From the perspective of paper, its own functions also determine that paper is a very good material, so it is very popular.

Paper has the following advantages:

(1) Paper has texture. It can be made into a three-dimensional shape or folded up. At the same time, it also has a very good effect as a display of goods.

(2) If air is added to the paper bag, it can produce a buffering force and heat insulation function.

(3) Paper can be used freely from heating 80 degrees to freezing -18 degrees.

(4) Printing on paper is both suitable and beautiful.

(5) Paper is light and cheap, and is also very convenient to transport.

(6) Paper itself is very environmentally friendly.

(7) Paper is very breathable, so it is very suitable for packaging vegetables and fruits.

(8) Paper is weak to water, but if other synthetic resins are added to paper, its functionality will be much stronger and it will not be afraid of water.

(9) Paper is very convenient to combine with other materials, and is a very suitable packaging material for use with other materials. In order to enhance the water resistance of paper materials, there are now many forms of plastic processing for paper, and this trend will become more obvious in the future.

Compared with bottles, paper is much lighter than glass bottles. At the same time, it also has great advantages in waste disposal. Both producers and users are very easy to handle. Since the processing of paper can achieve mass production and can be circulated in large quantities when used, it is now a typical packaging material that meets this requirement.

Nowadays, paper is widely used in the packaging of dairy products. Because paper is used, it is both hygienic and easy to transport. Therefore, paper is widely used in dairy product packaging. It can also be said that the use of paper packaging has made people's consumption life and cultural concepts change significantly. In the past, people usually used glass bottles to package dairy products. At that time, people did not have the habit of using dairy products in large quantities like today.

Because of the emergence of paper packaging and its convenience, people's demand for dairy products has become vigorous. It is precisely because of this change that people's physique has changed, making people's nutrition much richer. From the paper packaging of dairy products, we can see the close relationship between packaging and humans.

From the perspective of environmental protection, paper is easy to recycle and use, and it is a very suitable modern packaging material.
