With the development of market trends, food bags have developed into a variety of food packaging bags, especially food snacks. Foodies may not understand why there are many types of snack packaging. In fact, in the packaging industry, they also have names according to the type of bags. Let’s take a look at the main types of food packaging bags in life!
A back-sealed bag is a type of packaging bag with the back of the bag sealed. This type of bag has no opening and needs to be torn by hand. It is mostly used for granule packets, candies, dairy products, etc.
The second type: stand up pouch
The self-standing bag type food packaging bag is as easy to understand as its name. It can stand up independently on the shelf. Therefore, the display effect is better and more beautiful.
The spoutbag consists of two parts, the upper part is an independent nozzle/spout, and the lower part is a stand-up bag. This type of bag is the first choice for packaging liquids, powders and other products, such as juices, drinks, milk, soy milk, etc.
The fourth type: three side seal bag
As the name suggests, it is sealed on three sides and leaves an opening to contain the product. It is the most common type of food packaging bag.
Self-standing ziplock bags, that is, an resealable zipper is added to the top of the bag, which is convenient for storage and consumption and avoids moisture. This type of bag is flexible, moisture-proof and waterproof, and not easy to break.
This is a bag type developed on the basis of the stand-up bag. Since the bottom is square, it can also stand upright. This type of bag is more three-dimensional, with five panels: front, right side, left side, back and bottom. Compared with stand-up bags, flat bottom pouches have more printing space and product display, which can better attract consumers’ attention.
The above commonly used bag types are the most common on the market. I believe you already have a certain understanding of bag types after reading this.
