HOW ARE PLASTIC BAGS MADE?


We use a lot of plastic bags in the world today. In fact, nearly 1 trillion of them are created every single year. The bags can be found in many different places and have a versatile mix of uses, from carrying books to separating items to carrying groceries and all in between.


Plastic bags are popular for a number of reasons. The bags are very cheap and can be used for so many different purposes. And, despite what many people think, the bags can also be recycled and reused a number of times.


Creating a plastic bag is a fairly simple process, which is one of the reasons that they are so popular. Of course the process of creating the plastic bags is one that must be completed in a shop that has the right equipment, however, despite this fact, the bags are easy to make.


To create a plastic bag, the process is similar to the process for creating a book. Both are very easy to create, but the plastic bag is far easier to create than a book. A company must have special equipment to create the bag, however, there are just two steps required to make the bags.


The First Step


A process called extrusion is the first step in making a plastic bag. An extruder is used to heat the polyethylene plastic to a temperature of about 500 degrees F. This temperature will melt the pellets, at which time the molten plastic is pushed into the machine and a die that determines the thickness that the bag will have.   After this happens, the plastic film is pushed into a bubble by the outside air and through a cooling process. Next, the film is cut into the appropriate size and then placed onto a spindle.


The Second Step


Once the plastic bag is placed onto the spindle, it is sent to what is known as a conversion department. This team unwraps the film roll and cuts it with a heated knife that also seals each of the sides of the bags together. Once this is completed, the conversion also adds all of the special characters of the bag. Next, handles are cut out using a heat process, and logos, designs and text is added to the bag.


Creating Plastic bags


As you can see from the information above, creating plastic bags is a fairly simple and easy process that a company can do quickly and without a lot of trouble. Thousands of bags can be produced in only a minute of time, and since the process is so easy, it keeps the cost of the plastic bags down to an affordable price.


The Bottom Line


Plastic bags are very easy to create and they have so many different purposes that make them handy in our everyday lives. Now that you know how the bags are created you can feel so much better about using them! It is a process like none other.




   


 


Advantages of Plastic Bags



A woman carries a plastic bag.

It is easy to overlook the advantages of plastic bags due to the perception that they are environmentally unfriendly. While they certainly have ecological drawbacks, plastic grocery bags can be beneficial to retailers, consumers, and even the environment.




Advantages of Plastic Bags for Retailers


Retailers for have favored plastic bags as long as they have been available-about 50 years. The main advantages of plastic bags are that they are cost-effective, easy to use, and convenient to store.


Plastic bags are available in bulk purchases at a fraction of a cent per piece. In contrast, paper bags typically cost 5 cents or more per piece. Reusable cloth bags, which are gaining in popularity as environmental sustainability becomes a more widespread concern, can cost as much as a few dollars each. In large volume, plastic bags have obvious overhead cost benefits for stores and their profit margins.


In addition, plastic bags are quicker to open, pack, and double up than paper bags. While those few seconds may seem nominal, for busy cashiers, this can help keep lines moving efficiently. Plastic bags also require less space than paper bags, both in storage and at cashier stations, and weigh about one-tenth as much. Reusable bags take up the most space, and while their weight varies, they are all considerably heavier than plastic or paper bags.


Advantages of Plastic Bags for Consumers


Conveniently enough, just as retailers have found plastic bags to be a better option than paper, so too have consumers. The numbers speak for themselves: according to the U.S. Environmental Protection Agency (EPA), Americans use 100 billion plastic bags annually, and the American Forest and Paper Association estimates that Americans use 10 billion paper bags each year.


While this preference is gradually changing in light of environmental concerns and the increased use of reusable cloth bags, plastic bags still offer two key benefits:


Plastic bags are more durable than paper bags. They are less prone to tearing, easier to carry, and are far more useful in the rain.

Plastic bags are reusable for a variety of purposes, with many people using them as trashcan liners or to pack and store miscellaneous items. Plastic bags last considerably longer than plastic bags and be rinsed out and repurposed, unlike paper bags.

Environmental Impact of Plastic Bags


There has been much disagreement over whether paper or plastic bags are more detrimental to the environment. The truth is, each has advantages and disadvantages when compared to the other.




Environmental Advantages

There are several important ecological advantages of plastic bags over paper bags. Because they weigh so much less, they contribute far less solid waste to landfills when not recycled. According to the EPA, paper bag production requires 40 percent more energy than the production of plastic bags. Paper bag manufacturing also results in 50 percent more water pollution and 70 percent more air pollution than plastic bag manufacturing.


Environmental Disadvantages

The main ecological disadvantage of plastic bags is that they are manufactured from petroleum, a non-renewable resource. Paper bags, on the other hand, are made from trees, a renewable resource. Plastic bags are also not biodegradable, and break down into contaminating particles over many hundreds of years.


Effect on Marine Life

One of the more compelling arguments against the use of plastic bags is that marine life commonly mistakes them for food, and that this results in the death of 100,000 marine animals and 1 million sea birds annually.


However, this argument is false. The myth originated from a 2002 study on plastic bags commissioned by the Australian government. In the report, the authors misquoted a previous Canadian study from 1987. The animal deaths cited were actually attributable to fishing lines and nets, not plastic bags.


Remember to Recycle


Reuse your plastic bags as much as possible. Recycle the rest.


By recycling, consumers can avoid many of the drawbacks of plastic bags, such as their contribution to litter and their inability to biodegrade when discarded. There are numerous advantages of plastic bags, and by recycling them diligently, consumers can profit from their use in a more environmentally sustainable manner.


  





18 Ways to Reuse Plastic Bags:


Despite always bringing a reusable bag to the store, plastic grocery bags seem to make their way into my life. Maybe a well-meaning friend uses one to bring over snacks for a night of board games or I accept a used one to tote some goodies home from an unexpected garage sale.


No matter what the reason, I can never bring myself to get rid of all of that plastic. If you’ve got an ever-growing collection of plastic bags making you feel guilty, too, don’t despair! Here are some practical and crafty ways to use those bags over and over, and you can share your favorite ways to reuse plastic bags in the comments!


1. Dirty Clothes – Stick a plastic grocery bag into your suitcase to tote home your dirty clothes while you’re on vacation. It’s nice to be able to separate your clean clothes from dirty ones, and this lets you do it without taking the plastic bag that most hotels provide.


2. Make Plarn – You can cut those bags up and make yourself a ball of plastic yarn for use in all sorts of knit and crochet projects. How cool would it be to upcycle a flimsy plastic bag into a well-made, crocheted one?


3. Fuse It - You can use your iron to turn those plastic bags into durable fabrics.


4. Scoop the Litter Box – Flushing cat litter is a bit controversial, since cat waste contains toxins that’s harmful to aquatic life, and unfortunately, scooping is a fact of life for cat owners. You’ve got to put that smelly litter somewhere. You’re probably using a plastic bag already, so you may as well RE-use one instead.


5. In the Glove Box – If you or someone in your family is prone to car sickness, you can keep a plastic grocery bag in the glove box, just in case you’re not able to pull over in time to avert disaster.


6. At Concerts – Amphitheater shows and multi-day music festivals come with a lot of waste, and the trash and recycle bins seem to always overflow by the end. Instead of piling your empties on top of an overflowing bin, use a plastic grocery bag to take your recyclables home at the end of the show.

7. Dog Waste – It’s only polite to pick up after your pet, and many areas even provide disposal areas for dog waste. Rather than grabbing the plastic bag provided, you can re-use a plastic bag that made its way into your house.

8. Use Them Again – It may not be as fancy as pulling out a canvas grocery tote, but if you’ve got a bunch of those plastic bags around the house, bring them to the store to tote another load of groceries home.

9. Line a Paint Tray – Next time you’re painting a room, use a plastic bag to line the paint pan, rather than a disposable plastic pan liner. It takes less plastic, and it’s reuse to boot!

10. Protecting Valuables – Whether you’re packing to move or storing breakables in the attic, you can wrap them up in plastic bags to cushion them against damage.

11. Protect Your Paint Brushes – If you’re taking a break from painting, you can wrap the brush in a plastic bag to keep it from getting dry and hard. Just stick the wrapped up brushes into the fridge until you’re ready to get back to it.

12. Small Trash Can Liners – Reuse a plastic bag to line small trash cans, like in the bathroom, instead of buying new plastic 

13. Save Energy – Instead of sand, you can stuff a draft dodger with plastic bags.

14. Donate Them – Places like libraries and food banks often need bags.

15. Protect Plants from Frost – Protect your plants from a freeze by wrapping them securely in a plastic bag overnight and removing the bag in the morning.

16. In Your Suitcase – When you’re packing for a trip, stash your shoes in a plastic bag, so they don’t dirty up your clothing.

17. Shipping – If you’re mailing something fragile, wrap it in plastic bags instead of new bubble wrap.

18. Gardening – Tie a couple of plastic bags around your knees to add some padding while you’re working in the garden.

If worst comes to worst, you can also recycle those old plastic bags, instead of sending them to the landfill. Stores like Publix, Target, and Lowe’s will often take plastic bags for recycling. Make sure you call the store before you show up with a haul, though, since that policy can vary from town to town.
