Did you know that the liquid packaging we commonly see in daily life is made from special types of paper? Different liquids require different types of packaging paper, with two main types being regular liquid packaging paper and aseptic liquid packaging paper. But what’s the difference between them? Don’t worry—I’ll explain their production process, applications, and cost differences in this article.
As their names suggest, regular liquid packaging paper and aseptic liquid packaging paper are produced in different environments and through different processes.
Regular liquid packaging paper is produced in standard manufacturing facilities that meet basic hygiene requirements. These factories have general controls over dust, temperature, and humidity. The production mainly focuses on forming the paper and ensuring it can function as packaging. Processes like printing and bag-making are commonly involved, but there is no special sterilization step.
Aseptic liquid packaging paper, on the other hand, is produced in highly controlled sterile environments. These aseptic workshops maintain extremely high air cleanliness standards, often meeting ISO Class 7 (10,000-class cleanroom) or higher to strictly control microbial contamination.
In addition to regular paper processing, strict sterilization steps are applied. Methods like UV radiation, high-temperature steam sterilization, or chemical disinfection ensure the paper remains completely germ-free.
The choice between regular and aseptic liquid packaging paper depends on the hygiene requirements of the product.
Regular liquid packaging paper is suitable for liquids that do not require an extremely sterile environment, such as bottled water, fruit juices, and shelf-stable milk. Even if a small number of microorganisms are present in the packaging, these beverages can still be stored safely under normal conditions.
Aseptic liquid packaging paper is designed for products that are highly sensitive to microbial contamination, such as fresh fruit juices and yogurt without preservatives. These products have short shelf lives, and if contaminated, they can spoil quickly or pose health risks.
The cost of these two types of packaging paper differs significantly due to their production complexity.
Regular liquid packaging paper is more cost-effective since it is produced in standard facilities without specialized sterilization equipment. This reduces costs related to raw materials, machinery, and labor.
Aseptic liquid packaging paper is more expensive because maintaining sterile production environments requires advanced equipment and rigorous quality control. The cost of building and maintaining cleanrooms and implementing sterilization processes also significantly increases the cost of aseptic packaging.
