There are several kinds of bags that can be used for flour packaging, and each bag serves many purposes. Since there are a number of methods to package flour, you need to keep many factors in mind. The major factors are climate, the amount being packaged, the functionality offered, and local laws.
Food pouch manufacturers generally suggest different packaging techniques for big and small flour packets as the smaller ones are not very robust and may snap due to extra weight. Similarly, paper packaging is usually a better option in places where it is not possible to package wheat in plastic bags – due to either the law or public sentiments. But since paper bags are not robust, they can carry only a small quantity of flour.
The best dry food packaging also depends on the functionality of the bag. Some consumers like hang holes and zippers as they make the bag easier to store and reuse. Packaging should be done keeping consumers’ needs in mind.
Climate also plays an important role in deciding the right type of packaging. Flour bags in cold places require a different kind of packaging than flour bags that are going to be sold in a warm and tropical climate, as the heat expands the plastic.
