In today’s market, a wide variety of food packaging bags are constantly emerging, featuring diverse designs that are both aesthetically pleasing and imaginative. So, what are the common types of food packaging bags? Below, professional flexible packaging manufacturer Fuhehu Packaging will share with you.
1.Three side seal bag
This is the most common type of food packaging bag. The three-side-sealed bag features two side seams and one top seam, while the bottom edge is formed by horizontally folding the film. The bag can have or lack a fold edge; when present, it can stand upright on shelves. A variation of the three-side-sealed bag involves creating the bottom edge by folding the original edge and sealing it, effectively transforming it into a four-side-sealed bag in essence.
2.Stand up pouch
Doypack refers to a flexible packaging bag with a horizontal support structure at the bottom, which does not rely on any support and can stand on its own regardless of whether the bag is opened or not. This type of food packaging bag is also a common bag type in food packaging bags, which can stand independently on the container and has a good display effect. It usually comes with a zipper for easy carrying.
3.Back seal bag
Back sealed bag, also known as middle sealed bag, is a packaging bag that seals the edges on the back of the bag. The application range of back sealed bag is very wide, generally used for candy, bagged instant noodles, bagged dairy products, etc.
4.Flat bottom stand up pouch
Developed on the basis of self-supporting bags, the bottom is square and can stand upright, making the container display effect particularly beautiful. This type of bag has a three-dimensional effect and can stand on the shelf independently, making it convenient for sales and consumer consumption. There are three flat surfaces on the side and bottom for printing necessary information on color printed food packaging bags. There are more places on the front and side for advertising and beautification, which is conducive to promoting the brand and attracting consumers’ attention.
5.Spout pouch
The suction nozzle bag is composed of a suction nozzle and a self-supporting bag. The self-supporting bag is made of composite material, and the suction nozzle has a plastic bottle mouth. It is the first choice for packaging liquid, powder and other products, such as fruit juice, beverage, milk, soybean milk, soy sauce and so on. This type of food packaging bag is convenient for the transportation and storage of food.
