Some packaging methods for liquid packaging bags

The liquid packaging bag is a large shopping mall, which includes soybean milk for breakfast, juice in the afternoon, and milk before bed. Therefore, the demand for liquid packaging is very high, and it is the main order method for flexible packaging enterprises. Let me share with you some packaging methods for liquid packaging bags:

In the past, liquid packaging bags were mainly self-supporting bags and penguin bags. However, with the increasing demand from customers for packaging appearance, functionality, and the expansion of the entire shopping mall, in the past two years, more and more large food and beverage enterprises have chosen flat bottom bag packaging methods. Among them, the popular one is the octagonal sealed flat bottom bag liquid packaging, which is popular among customers due to its beauty and applicability.

Square bottomed bags for liquid packaging are the mainstream of shopping malls and are loved by food companies. If flexible packaging enterprises can advance the consumption power and waste rate of square bottomed bags for liquid packaging, it will effectively enhance their competitiveness in the industry. The square bottom bag displays five sides and has a larger space than the self-supporting penguin bag, satisfying the needs of customers. The square standing bottom makes ample use of shelf space, suitable for the expansion of large supermarkets.

Liquid packaging has high requirements for sealing and heat sealing strength during the bag making process. When selecting composite bags with different structures, different heat sealing temperatures, pressures, and times need to be set. Once there is an error in the operation, the product will become scrap, the scrap rate will increase, and the cost of bag making will also increase accordingly. Therefore, this requires flexible packaging companies to understand the functional characteristics of composite bags, be proficient in operating relevant bag making machines, and be able to promptly handle problems during the consumption process.
