Pollution from plastic bags.
The plastic bag is a common object used to carry small amounts of
merchandise. Introduced in the 1970s, plastic bags quickly became very
popular, especially through their free distribution in supermarkets and other stores.
They are also one of the most common forms of conditioning household waste and,
through their decoration with brand symbols, they constitute a cheap form of advertising
for the stores that distribute them. Plastic bags can be made of low-density polyethylene.
density, linear polyethylene, high-density polyethylene or polypropylene, plastic polymers not
biodegradable, with a thickness varying between 18 and 30 micrometers. Annually, they circulate throughout the
world between 500 billion and one trillion of these objects.
1.1 Pollution of plastic bags in the sea.
To raise our awareness a little more about the subject:
For the next 150 years, the remains of the bag will be tumbling around the bottom of the sea.
they will be broken down into smaller pieces and will be ingested by fish that will incorporate them into the
food chain. In this coastal area, off the beaches of Catalonia, every kilometer
Square of the seabed houses an average of 1,943 pieces of plastic, many of them quite
thicker than a bag and will take hundreds of years to disappear.
1.2 How it affects the environment.
The most serious thing is that plastic bags, manufactured primarily from oil and gas,
they have an estimated lifespan of 1,000 years, before breaking into small toxic particles. Thus, the
The invasion of this garbage presents an alarming path of accumulation towards the future: according to
with the Environmental Agency of the United States, currently between
500 billion and one trillion plastic bags per year.
Some will say it is a luxury that only wealthy nations can afford, ignoring that many
developing countries are battling, such as Bangladesh, China, Kenya, South Africa, and Thailand. In
China prohibited the manufacture, sale, and use of plastic bags with a thickness less than 0.00098
inches -or last bags of the market-, as well as the free supply of those that are larger
thickness. The regulation, issued last December 31, urges citizens to
return to cloth bags and baskets for shopping.
1.3 How they deplete natural resources.
In general, the manufacturing process of a plastic bag includes the extrusion of the resin, whether
by blowing method or through a die; the printing can be by the flexographic method
or rotogravure (also known as gravure), there can be a varnishing or laminating process with
another layer of plastic, and finally the welding or sealing process through heat and pressure. It is
a large global industry that enables the preservation and transportation of food,
brand recognition, consumer protection against counterfeit brands or companies without references
of contamination by external agents, of preservation of nutritional and organoleptic qualities
of the food, etc.
Of the amount of oil extracted worldwide, only 5% is used for the industry.
Plastic; most of it is used for car parts such as trim, interiors,
boards, etc.; other types of products such as phones, refrigerator interiors, cabinets of
television, etc. Another very high proportion is represented by soft drink bottles, beverages, liquids, etc.
Only a minimal part of this total is used to manufacture plastic bags. The bags pollute.

starting to charge for plastic bags. In these countries, the bags they give you in the
establishments are made of paper

3. What affects plastic bags the most.
Plastic is very present in our lives, without us realizing the dangers it poses.

Measures to significantly reduce the use of plastic bags.
Plastic is part of our lives. We are so accustomed to it that we do not stop to
think about the figures that demonstrate the terrible consequences of its excessive use.

The benefits of an eco-friendly bag are many, there are fewer expenses, you take care of the environment, there are fewer
