When we buy food in the mall, we can often see many standing food items. Many of the standing food packaging bags are self-supporting bags and octagonal sealing bags. So which are self standing bags and which are octagonal sealing bags? How should we distinguish? Next, Xiao Bian will introduce to you the difference between a self-supporting bag and an octagonal sealing bag.



1、 What kind is the octagonal bag


The eight side sealing bag is also called the eight side sealing flat bottom bag. Its bottom is flat, and there are eight edges in total, so it is named. There are 4 edges at the bottom, 2 edges on the left and 2 edges on the right, totaling 8 edges. There are five display surfaces in total: one at the front and one at the back, one at the left and one at the right, and one at the bottom. In this way, the octagonal bag can carry more information media information and better display and promote food and brands.


2、 What is a self supporting bag


On the Internet, many people define packaging bags that can stand on their own without relying on external support as self-supporting bags. Xiao Bian thinks that such a definition is easy to confuse self-supporting bags, four side sealing bags and eight side sealing bags. Xiao Bian gives such a definition: a packaging bag with folding back at the bottom and two edges, one edge on the left and one edge on the right, and the bottom can stand on its own after being stretched.


3、 Difference between self-supporting bag and octagonal sealing bag


After the previous description, the difference between the two is very obvious.


1. First of all, the bottom of the self-supporting bag is not flat, and the bag is sealed on eight sides;


2. Secondly, the number of edge seals is different. There are 4 independent bags and 8 eight edge seals;


3. The number of display surfaces is different. There are only two self-supporting bags and five eight sided sealing bags.


On the whole, the octagonal sealing bag is more superior, more three-dimensional and more stable than the self-supporting bag; The cost is more expensive and the technical requirements are higher.


Although self-supporting bags and octagonal sealing bags are different in cost, they are all food packaging bags that can be sold upright, which depends on how
