Paper barrels have good prospects for development and application, and can be used as substitutes for metal, glass, and ceramic packaging containers. Compared with these packaging containers, composite paper drums have more obvious advantages. Their main features are: as they are mainly made of paper, they are easy to recycle and process; Excellent protective performance, waterproof and moisture-proof, and has a certain insulation effect; Odorless, non-toxic, safe and reliable, especially suitable for food packaging; Can be filled with products of various shapes with low noise during filling; Can withstand positive and negative pressure, and can be used for vacuum or nitrogen filled packaging; The design structure is diverse, and the outer layer can be color printed, which has a good display effect; Lightweight, only 30% of the weight of an iron drum, easy to circulate, convenient to use, and relatively low in price.

Application areas of paper buckets   

The application fields of composite paper drums are very wide. In addition to being commonly used for powdered solid foods such as cocoa powder, tea, sugar, salt, cereal, coffee, and various solid beverages, they can also be used for various liquid foods such as juice, wine, mineral water, milk, etc. It can also be used for health foods, oilseed foods, frozen concentrated foods, etc. that require high moisture resistance. For example, about 85% of concentrated orange juice in the United States is packaged in composite paper barrels. More than 50% of soft drinks are packaged in composite paper barrels with aluminum easy to pull lids.

In addition, paper drums can also be used for specialized packaging technologies, such as vacuum packaging, including "dry" vacuum packaging for coffee, milk powder, peanuts, and "wet" vacuum packaging for concentrated juices and seasonings; Pressure packaging, including nitrogen filled fast food packaging and carbonated beverage packaging. But composite paper drums are not suitable for packaging frozen and thermally processed foods
