What is a Paper Making Machine?


I know you’re looking for a paper bag machine that’s why you are here.


Maybe, you want to be a paper bag wholesaler or make branded designs for your retail business.


The truth is, paper bags are dear packages for food vendors, retailers, and even manufacturers.


But, how can you venture in this business?


Or, what is the most cost effective way of making paper bags?


Today’s guide debunks the facts behind paper bag making process and machine such basic definition, working principle, classification, design, technical specification, etc.


So stay with me to be an expert in paper bag making industry.


Let’s begin with some facts.


Apart from the other devastating problems associated with plastic bags, did you know that synthetic bag manufacturers produce about one trillion of those bags in a year globally?


Did you also know that it takes one thousand years for a single bag of this kind to biodegrade?


Yes, that’s the scariest part of it.


Due to that, most governments are imposing bans on these carriers.


The alternative?


A mega-shift to more environmentally friendly paper bags.


So basically a paper bag making machine is a state of the art machine that gathers, folds, stamps, and processes papers to produce clean paper bags.


These paper bags are for use in the packaging of goods in various industries such as food, pharmaceutical products, grocery, and baking industries.


The bag making machines come in various configurations depending on the type of bags for final production.


Therefore, the paper bag making system should be versatile enough to cater to the dynamics in the paper bag manufacturing.


Today different paper bag making stakeholders such as the machine manufacturers, raw material suppliers face a lot of shifting customer demands, government regulations, changing prices, etc.


It’s thus good only if the machine can afford the manufacturer some relief.


For that matter, it means that you need to know all the factors related to the paper bag making the machine.


Besides, all the accompanying dynamics before making a purchase.


Luckily, I have compiled all that you need to know in this article.


The history of development and use of paper bag making machine dates back to the 19th century.


During these early stages, the systems were simple and mechanically operated.


With that, we move to the next step.


Where to Use Paper Bag Making Machine


Take a moment to reflect on the occasions you use a paper bag.


Indeed paper bag forms a vital integral in our lives today.


From simple uses such as carrying random goods to more complex ones such as in pharmaceuticals to wrap up drugs.


One thing is for sure.


Without paper bag making machine, we would be missing a significant aspect of our lives.


Surely, there are numerous uses of paper bag making the machine.


Subsequently, the produced paper bags can be classified under different distinct categories depending on their purposes.






We carry stuff in them -– groceries, clothes, gifts, trash and booze. I carried my lunch to school in one until the fourth grade because my mother would decorate them with stickers and drawings. People add sand and candles to them to illuminate their neighbourhoods at Christmas. Disgruntled sports fans cover their heads with them. But how many people know where the flat-bottomed paper bag came from? Or that its invention was a triumph of feminism over patriarchy, and of brains over bullying?


For most of recorded history, containers were made of leather, wood, cotton and reeds. Paper, made by hand one sheet at a time, was a luxury, used only for books, records and letters by the literate few. In 1799, a French inventor named Louis-Nicolas Robert was granted a patent for a machine that produced rolls of paper. This invention brought paper to the masses. Soon, merchants were using rolled paper, or ‘cornucopias’, to package small quantities of goods, with predictably messy results. They also constructed rudimentary paper bags by hand, which was a time-consuming and not always successful process.


The race was on to produce a paper bag that was both sturdy and easy to make. In 1852, the American Francis Wolle received the first patent for a square bottom paper bag machine. It used steam and paste to create bags in the shape of envelopes. Though the machine became popular, the bags it produced were cumbersome and of limited use – picture a load of groceries in a large envelope-shaped sack. Still, they were better than nothing at all, and factories producing the bags multiplied. In the late 1860s, Margaret Knight, a tall, endlessly inquisitive and hard-working New Englander, went to work for the Columbia Paper Bag Company in Springfield, Massachusetts. Within a few years, her ingenious designs would revolutionise the industry.


Born in 1838, Knight’s childhood was shaped by the industrial revolution. At first glance, hers is the classic victim’s story – raised by a widowed mother, and put to work by the age of 10 in the brutally inhospitable cotton mills of New Hampshire. But from her earliest days this uneducated labourer had an agile, inventive mind. While still a child, Knight saw a fellow worker injured when a steel-tipped shuttle shot off a loom. She soon created a shuttle cover to prevent any more accidents, and her invention was adopted by her factory. In an interview with the progressive Woman’s Journal in 1872, she recalled her unconventional youth: As a child, I never cared for things that girls usually do; dolls never possessed any charms for me. I couldn’t see the sense of coddling bits of porcelain with senseless faces: the only things I wanted were a jack-knife, a gimlet, and pieces of wood. My friends were horrified. I was called a tomboy; but that made very little impression on me. I sighed sometimes, because I was not like the other girls; but wisely concluded that I couldn’t help it, and sought further consolation from my tools. I was always making things for my brothers; did they want anything in the line of playthings, they always said: ‘Mattie will make them for us.’ I was famous for my kites; and my sleds were the envy and admiration of all the boys in town.


By the time she joined the Columbia Paper Bag Company as a lowly factory worker, the 30-something, unmarried Knight had spent years as a ‘Jill-of-all-trades’, becoming proficient in daguerreotype, photography, engraving, house repair and upholstering. Spending long hours at the factory, she soon heard of current efforts to create a flat bottom paper bag machine that could efficiently manufacture flat bottom paper bag. ‘I am told that there is no such machine known as a square-bottomed machine,’ she wrote in her journal. ‘I mean to try away at it until I get my ideas worked out.’ Independent of the factory and without her bosses’ knowledge, Knight began to study the issue intently.


By 1867, she was hard at work on creating a machine that could ‘cut, fold and paste bag bottoms itself’. Her work kept her up at night, leading the manager of her boarding house to declare: ‘I saw her making drawings continually… always of the machine. She has known nothing else, I think.’ Her work on the machine also bled into her shifts at the factory. This initially annoyed her superiors – until she showed them her plans – which led them to believe that she had a ‘keener eye than any man in the works’. After a ‘rickety’ wooden model of her machine proved successful, producing thousands of ‘good, handsome bags’, she had an iron version produced in 1868. While the machine was at a Boston shop to be refined, it was viewed by Charles F Annan, a would-be-inventor of dubious morality.


Knight prepared to apply for a patent for her new machine. In 1871, she was shocked to find that Annan had already been granted a patent to the machine, which he claimed as his own. The dispute ended up in court, where the cash-strapped Knight spent $100 a day to hire a patent attorney to prove that she was the machine’s true inventor. Annan’s lawyer argued that an uneducated, self-taught woman could never have built such a sophisticated machine. He was countered at every turn by the mountains of physical evidence and eye-witness testimony Knight produced. ‘I have from my earliest recollection been connected in some way with machinery,’ Knight protested. In the end, the commissioner of patents found in favour of Knight, though officials could not resist chastising her for waiting so long to apply for her patent. However, since Knight was not a ‘man of business’, this oversight was forgiven.


On 11 July 1871, Knight was granted patent number 116,842 for her ‘new and improved shopping paper bag machine for making paper bags’. She soon formed the Eastern Paper Bag Company with a partner, and became a media darling for her revolutionary machine, which did the work of 30 labourers. The new stand-alone, flat-bottomed bags were quickly adopted by large department stores and grocers, and Knight was awarded a royal honour from Queen Victoria. In 1883, Charles Stilwell of the Union Paper Bag Machine Company, working from Knight’s patent, further advanced the paper bag with his invention of a machine that produced the Self-Opening-Sack (SOS), the pleated flat-bottomed bags that are used today.


The vivacious Knight, dubbed by one paper the ‘lady Edison’, would spend the rest of her long life – she died aged 76 in 1914 – inventing. By 2006, when she was inducted into the Paper Industry International Hall of Fame, it was estimated that around 25 billion paper sacks were used annually throughout the world.


In the past decade, Knight’s dramatic story has been told in two popular children’s books – Marvelous Mattie (2006) by Emily Arnold McCully, and In the Bag! (2011) by Monica Kulling. She is emblematic of a whole multitude of female inventors, such as Mary Anderson (the windshield wiper), Katharine Blodgett (non-reflective glass), and Stephanie Kwolek (Kevlar), who created life-changing inventions within industries – and a world – dominated by men. Their stories are important and should be better known. They can inspire future generations of girls and young women to tinker, experiment and invent.
