Retailers use branded paper bags as a blank canvas for the packaging of their branded products.As you can imagine, the invention of a convenient, disposable container was revolutionary. Business owners can store stacks of these bags in their stores, and their low cost and ease of use make them readily available to even low income shoppers. As a result, white paper bags have become an essential part of people's lives.
As an indispensable commodity in life, paper bag is a great invention. What material ispaper bag made of? The paper bag makingbegan in 1879, when a German chemist named Karrh Vegeta first came up with the method of making kraft paper. If you look at the history of kraft paper bags , you can see how it was made. Specifically speaking, it goes like this: Wood chips are exposed to high temperatures, and then they break down into solid pulp and by-products. The pulp is then sifted, washed and bleached to form the familiar brown paper. The advantage of this pulp process is that it makes kraft paper particularly strong and durable, so heavy lifting is not a problem.
Materials
Then we looked at what determines how much a paper sack can hold. The load-bearing capacity of paper bags depends on the following factors:
First,recycled paper bagsare different from jute, canvas, burlap, they are made of pulp, which greatly reduces the cost of paperbags, making them the first choice for transportation.So, the paper bags price is very cheap.
When choosing paper bags, especially when you need to carry large or heavy items, there are other aspects to consider besides materials when choosing the product that best suits your needs, to choose the perfect paper bag
Base weight of paper
The base weight of paper, also known as the g weight, is used to measure the density of paper, is an important reference factor, in pounds, a pound is equal to five hundred reams. It is well known that the greater the number, the greater the density of the paper, and thus the heavier the weight.
Stiffened Plate
The stiffening plate is a reinforced area that is joined with other materials to reinforce the bag. The purpose of the stiffened plate is to provide a support to the bottom of the paper bag to prevent the paper bag from breaking. Gusseted paper bags can hold heavier items and are less likely to break.
Twist Handle
At the top of the paper bags with handlesthere will be a twist handle, used to lift thesmall paper bag, is also a load-bearing device. The twist handle is made by twisting natural kraft paper into a rope, which is then glued to the inside of the bag. The twist treatment is usually used to reinforce the rope to increase the weight that the bag can carry.
