1、 What is an octagonal sealed bag?

As the name suggests, there are eight edges, with four edges at the bottom and two edges on each surrounding surface. The octagonal sealed bag type is a new bag type that has only emerged in the past two years. Nowadays, many well-known e-commerce brands are using this type of bag, typical of which are Three Squirrels, Loulan Ganyan, Qilixiang, and so on. The octagonal sealed bag, due to its good three-dimensional effect, looks more layered and is widely loved by customers.

2、 What are the advantages of octagonal sealing bags?

The octagonal sealed bag is the most suitable flat bottom bag type for film materials among the three types of flat bottom bags. This packaging combines the advantages of thin film materials and the visual performance of a flat bottomed standing shelf, which increases the volume compared to traditional self-supporting bags. It is a new choice for upgrading traditional thin film upright bags. It can be added with a zipper for easy reuse, avoiding the disadvantage of not being able to add a zipper to the organ bag. It can also be equipped with a one-way exhaust valve.

The advantages of octagonal sealing bags can be summarized as follows:

1. Promote competition in food and increase food sales.

2. Protect food and extend its shelf life.

Throughout the entire circulation process, food needs to be handled, loaded, unloaded, transported, and stored, which can easily cause damage to the appearance and quality of the food. After the food is packaged inside and outside, it can effectively protect the food and avoid damage.

Throughout the entire circulation process, the quality of food may change and deteriorate. Food itself has a certain amount of nutrients and moisture, which is the basic condition for the production and reproduction of bacteria, mold, yeast, etc. When the temperature of food preservation is suitable for their reproduction, it can cause food to rot and transform. Assuming that food is packaged in sterile packaging or subjected to high-temperature sterilization, refrigeration, etc. after packaging, it will avoid the occurrence of food spoilage and extend the shelf life of the food.

Together, food itself has a certain amount of moisture, and when the content of this moisture changes, it can lead to changes or deterioration in the taste of the food. Assuming that the corresponding moisture-proof packaging techniques can avoid the occurrence of the above phenomenon and effectively extend the shelf life of food.

Furthermore, when food is directly illuminated by sunlight and lights during circulation, it is prone to oxidation, discoloration, and flavor change. For example, using appropriate vacuum packaging, inflatable packaging techniques, and packaging materials can also effectively extend the shelf life of packaged food.
