All kinds of packaging bags emerge in endlessly in the market, which makes people dazzling. However, according to the structure of the bags, we can initially divide them into three-sided packaging bags, four-sided packaging bags, eight-sided packaging bags, medium-sealed packaging bags, self-supporting bags and other basic bag types. After adding different functional accessories, bag types with outstanding functional characteristics such as zipper bags and suction nozzle bags appear. 1. Three side seal bag Three-sided sealed bags are the most common type of bags. The bags received by customers are sealed on three sides, and the last side is sealed by the customer after loading. This kind of bag can be easily torn or zippered to meet more personalized needs. Three-sided sealed packaging bags are commonly used in various condiment packaging bags, such as chicken essence, monosodium glutamate, etc. Some snack products will also choose three-sided sealed packaging bags. Compared with other bags, the cost of three-sided packaging bags will be lower. For price-sensitive products, such packaging can be used to control production costs and increase product profits. 2. Four side seal bag Four-sided packaging bags are common in bread packaging bags. The left and right sides of this packaging bag have folded edges. The space is larger than that of three-sided packaging bags. It can hold more products. The overall shape is also more three-dimensional and higher-grade than three-sided packaging. Some nut products and miscellaneous grain products will also use this packaging bag. 3. Eight side seal bag The eight-side sealed packaging bag is more three-dimensional than the four-side seal. In addition to the left and right side folds, the bottom is also folded. After the product is filled, the bottom can be flattened to achieve a self-supporting effect, so as to better display the product. This kind of packaging bag, in the nut snack products are more common, is to enhance the product grade of choice. 4. Self-supporting bag It is also a packaging bag that can achieve self-supporting effect. Unlike the eight-sided packaging bag, the self-supporting packaging bag adds a separate oval bottom at the bottom. After the product is filled, the bottom is fully stretched out to achieve a self-supporting effect. The display effect of this self-standing bag is similar to that of the eight-sided seal, but the overall space is slightly insufficient, and the three-dimensional effect is relatively weak, but the cost is lower than that of the eight-sided seal, which is more suitable for friends who need to improve the product grade but want to control the cost. 5. Medium-sealed packaging bag The middle seal packaging bag is a bag type with obvious characteristics. In the middle of the back of the bag, there will be an obvious extra sealing edge, so it is also called back seal bag. The most common packaging of this kind of bag is candy, ice cream, dumplings, rice, flour and other products. Like the three-sided seal, the middle seal bag has the advantage of lower cost, but unlike the three-sided seal, the middle seal bag has a wider applicability and higher expandability than the three-sided seal, which can meet some personalized packaging requirements on the premise of controlling costs, such as increasing the capacity by folding the left and right sides. 5. Zipper bag/suction nozzle bag Zipper bags and suction nozzle bags are personalized bags evolved from the basic bag type by adding zippers and suction nozzles. At present, self-sealing zipper bags are very common and can be seen in various bag types. The suction nozzle bags are commonly packaged in jelly and ketchup. Of course, some bagged beer is also packaged in suction nozzle bags.
