Paper bags, sacks and packaging
Paper bags, sacks and packaging are made of paper, typically combined with other materials such as laminate or foil, which improve the product properties, chiefly its strength and water resistance. Processes that use combinations of these materials also enable high-quality printing, making the paper bags and various paper packaging attractive to the end user.
Single-wall paper bags
Single-wall paper bags are most commonly used in shops. They include food bags, bread bags, and recyclable (brown) bags. They are all made from a single layer of paper and can be printed on. The manufacturer's or vendor's logo is the most common theme.
Single-wall bags are not water-resistant, but they can be laminated, for example.
Multi-wall paper packaging (sacks)
Multi-wall paper packaging is made from multiple layers of sack paper. Sacks made from it are very strong and typically intended for transporting larger volumes. Typical examples are bags for cement, animal fodder, larger packs of food such as sugar, flour, and so on.
Bag bottom shape
Paper bags were handmade, only by gluing the side walls together, until 1870. Bags were improved by using a flat rectangular bottom and a bag-making machine. At present, bags are made with various bottom shapes depending on their use: rectangular, square, or hexagonal. The cone is a special paper bag shape, mostly used in the food industry.
Materials for making paper bags
Paper, foil or paper with foil are the basic materials for making paper bags and packaging. The process of making the final shape of the paper bags - by gluing or fusion - is chosen depending on the material used.
Combinations with other materials are used to modify the paper bag's properties, especially to improve its strength and water resistance.
Sack paper is used for larger paper bags and packaging, especially for multi-wall paper packaging such as paper sacks as well as shopping bags, etc.
Sack paper is made of softwood cellulose. Microcrepping is used in the manufacturing process to make the material porous and elastic. The paper has to be both elastic and strong. Sack paper can be coated with polythene to increase its resistance to moisture or bacteria.
Recycling paper bags
Bags, shopping bags and sacks made of paper are fully recyclable. However, increased attention is required when disposing of products that combine paper with other materials.
History of paper bag manufacturing
The US inventor Margaret Ethridge Knight (1838-1914), holder of 87 US patents, invented the paper bag-making machine. Her other inventions include the calculator, the rotary motor, the shoe cutting machine, and the sash window frame.
After the Civil War, Margaret Knight worked in a paper bag factory in Massachusetts. She realized it would be much more practical for the bags to have a flat rectangular bottom. Until then, bags were made by simply gluing the side walls together.
Margaret E. Knight made a wooden model of a machine for making flat-bottom paper bags, but the patent office required a metal model to certify the patent. She therefore had one made. However, Charles Annan copied the metal bag-machine model in the workshop that was making it, and had it patented himself. This led to a lawsuit in which Margaret E. Knight was awarded the patent in 1871. She established Eastern Paper Bag Co. together with an investor, which was known as the "mother of lunch bags".
M. E. Knight was awarded patent no. 116842 on 11 July 1871.
Paper bags are made without or with printing. Bag printing is done when the bag is still just a strip, before the shape is formed. Another material, better suited to better-quality printing, is applied on the base paper layer to improve the printing result, especially on shopping bags. Coating or laminating machines are used for this treatment.
