Various types, large and small paper bags seem to have become a part of our life. Externally simple, atmospheric, internal environmental protection, safety, seems to be our consistent perception of paper bags, but also the main reason why businesses, customers choose paper bags. Paper bags are mainly made of the following materials

1. White cardboard

The advantages of white cardboard: solid, relatively durable, very good smoothness, printed out in a rich and full color. Paper bags commonly used 210-300 grams of white cardboard, often used more than 230 grams of white cardboard.

2. Copper plate paper

The material characteristics of coated paper: whiteness and gloss are very good, printing can make the picture and picture reflects the three-dimensional sense, but its solidity than white cardboard. Paper bags commonly used to the thickness of coated paper 128-300 grams.

3. Kraft paper

The advantages of kraft paper: a high degree of toughness and solidity, not easy to tear, kraft paper is generally suitable for printing some single-color or two-color paper bags that are not rich in color. Commonly used size is:120-300g

Swedish Sten Gustav Thulin in 1959, the original intention of the invention of plastic bags, is to replace paper bags. At that time people use a lot of paper bags, resulting in massive deforestation.

Compared with paper bags, plastic bags have the advantages of light and strong, water, not easy to break, was invented after the widespread use, and in fact, more easily reused than paper bags.

But the problem is that these bags are too cheap, too convenient and too easy to obtain, so that lazy people throw away after use. Plastic bags were invented when they were not disposable, but because of people's use habits become disposable.

Non-biodegradability is considered to be the original sin of plastic bags, yet its destructive power is often tied to low recycling rates. The words "non-biodegradable" sound very appalling, but in fact, in addition to plastic products, metal products and glass products are also non-biodegradable, glass products take about 1000 years to decay naturally, which is five times more than plastic products.

Humans can not ban all these materials together, so the key to the problem is whether these non-degradable materials can be properly disposed of. The embarrassment of plastic bag disposal is that burning will pollute the atmosphere, landfills and pollute the land, then recycling becomes its best destination. And plastic can be recycled many times.

The main material for the production of paper comes from trees, which is the reason why plastic bags were invented to replace paper bags.

There are statistics, the current global annual volume of household paper reached 320 million tons, the production of a ton of paper needs to use about four 20-year-old trees, then the world needs to cut down 1.28 billion trees a year.

If all the paper bags to replace plastic bags, meaning that the deforestation area will be expanded, that basically back to the 1950s the old way to go. In addition to the felling of trees, paper pollution is also easy to be ignored, in fact, the pollution of paper may be greater than the manufacture of plastic.

Plastic material as one of the greatest inventions since the 19th century, it is not wrong, what is wrong is the way we use and dispose of it has problems.
