For growing food manufacturers, bulk aseptic drums often become the right ingredient format when pouch and canned options stop making operational sense. Production volume increases. Ingredient cost pressure builds. Warehouse handling time per case starts to outweigh the convenience of smaller packaging. At that point, switching to bulk aseptic drums becomes one of the most common procurement decisions in scaling food production.
However, the move raises practical questions. How is product physically removed from a sealed drum? What equipment is needed? Can a smaller manufacturer convert without major capital investment? And what changes in day-to-day operations once bulk aseptic drums replace pouches on the production floor?
At One Source Food Solutions, we work with food manufacturers, co-packers, and private label brands across every stage of the scale-up curve. Many of our partner relationships begin with this exact format change, so we have direct experience with what works, what requires planning, and how to match aseptic drum handling methods to the realities of each operation.

Why Food Manufacturers Move to Bulk Aseptic Drums
The primary driver behind switching to bulk aseptic drums is ingredient cost efficiency. Aseptic tomato drums deliver tomato paste, diced tomatoes, purees, and sauces at a meaningfully lower cost per pound than smaller pouch or canned formats. The difference reflects reduced packaging material, more efficient freight loading, and lower per-unit processing costs at the supplier facility. Even after accounting for equipment investment, the per-pound economics typically favor bulk aseptic drums once production reaches a sustained scale.
Bulk aseptic drums also offer operational advantages for high-volume kitchens. A single 55-gallon drum of bulk aseptic diced tomatoes holds approximately 475 pounds of product, equivalent to dozens of smaller pouches. Fewer packages handled means fewer touchpoints, less packaging waste, and reduced opportunity for handling error during production setup. For a deeper comparison of available formats, our guide to tomato paste packaging options breaks down the cost and operational tradeoffs across drums, totes, cans, and pouches.
What Bulk Aseptic Drums Actually Are
Understanding the format is essential before planning to use bulk aseptic drums on a production line.
Each aseptic drum is a fiber outer container, similar in appearance to a traditional barrel, with a sealed plastic aseptic bag inside. The aseptic bag in drum is what actually holds the product. Before filling, the bag is sterilized in a controlled environment. Hot, commercially sterile product is then aseptically filled into the bag, after which the bag is closed and the fiber drum is secured around it. The process follows FDA aseptic processing and packaging requirements, which require commercial sterility for the product, the packaging equipment, and the packaging material.
This bag-in-drum design is the reason bulk aseptic tomato products achieve a minimum 24-month shelf life at ambient temperature without preservatives. The sterilized bag preserves the sterilized product. Refrigeration is not required, and no preservatives are added to extend shelf stability. Consequently, aseptic tomato drums can be stored in standard warehouse conditions until the moment of use, which simplifies inventory planning compared to refrigerated or frozen ingredient formats.
How to Use Bulk Aseptic Drums on Your Production Line
When a drum is ready for production use, the goal is to transfer product from the aseptic bag into the batch tank, kettle, or production line with minimal product loss and no contamination of the open bag.
The opening procedure is straightforward. Loosen the locking band that secures the lid on top of the drum. Inside, an aseptic bag will be visible, with a round fitment at the top. This fitment was used during filling and is not the access point for evacuation. Instead, cut an X across the top of the bag to create four triangular sections. Pull each section up and over the rim of the fiber drum. Then use the original locking band to secure those four sections firmly to the top of the drum, holding the aseptic bag in drum place against the rim.
Once secured, the bag is ready for product removal. The bag remains inside the fiber drum throughout the process, and removing the aseptic bag from the drum is not recommended because it creates handling and stability problems.
From this point, there are four common methods to move product from the aseptic bag in drum into the production line. The right choice depends on production volume, available capital, and the physical properties of the product being handled, especially viscosity, which differs significantly between diced tomatoes in juice and high-Brix paste formats.
Food-Grade Pails and Shovels
Manual transfer with food-grade pails or shovels is the simplest option for using bulk aseptic drums. Operators scoop product directly from the open drum into pails or onto shovels and carry it to the batch tank. For very high-viscosity products such as cold break tomato paste, shovels often work better than pails because they allow operators to lift larger volumes per scoop.
This approach requires the lowest equipment investment and works well for smaller production runs or for operations converting gradually from pouch formats. However, it is the most labor-intensive option and produces the slowest throughput. Pails and shovels often serve as bridge solutions during the first months of bulk aseptic drum use while the operation evaluates volume and confirms that the format change is sustainable.
Food-Grade Pump Systems
A sanitary food grade pump is the most common scaled solution for ongoing drum-based production. Pumps draw product directly from the open aseptic bag through a sanitary line into the batch tank, eliminating manual transfer entirely.
Food grade pump systems require upfront capital and dedicated sanitation protocols, but the throughput and labor savings justify the spend for operations using multiple drums per production run. Food grade pump selection depends on the viscosity of the product being handled. Diced tomatoes in juice pump differently than 31% NTSS cold break paste, and equipment specifications should be matched to the dominant product category in your production schedule.
Forklift Drum Dumper Attachments
The highest-throughput option for emptying bulk aseptic drums is a forklift drum dumper attachment. These attachments clamp around the drum, lift it, and tilt it forward, pouring the contents directly into a receiving tank or batch vessel.
A forklift drum dumper requires both a forklift and adequate ceiling clearance above the receiving tank. For operations with the necessary infrastructure and high enough volume to justify the equipment, a forklift drum dumper offers the fastest cycle time and the lowest per-drum labor cost. These attachments are commonly used in larger sauce, soup, and beverage production environments.
Matching the Aseptic Drum Handling Method to Your Operation
There is no single right answer to bulk aseptic drum handling. Small and growing manufacturers frequently begin with pails or shovels to validate the format change before investing in equipment. As volume confirms and the operational case for aseptic tomato drums solidifies, those manufacturers upgrade to food grade pump systems or forklift drum dumpers in line with production scale. Larger established operations typically standardize on pumps or dumpers from the start.
We help our partners think through these tradeoffs as part of the sourcing conversation. Equipment decisions affect freight planning, warehouse staging, and batch scheduling, and getting them right before the first drum arrives reduces operational friction during the rollout.
What Changes When You Switch from Pouch to Bulk Aseptic Drums
The physical handling of product is only one part of the conversion. Several operational considerations also shift when bulk aseptic drums replace pouches on the production floor.
Storage planning changes. Aseptic tomato drums are stored on pallets at four drums per pallet, and they require more warehouse footprint per case than equivalent pouch volume. However, the longer shelf life of unopened aseptic drums often offsets the footprint difference by allowing larger purchase quantities and less frequent reordering.
Batch planning also changes. Once an aseptic bag is opened, the product must be used immediately. Unlike pouches, which can be opened, partially used, and resealed for short-term storage, bulk aseptic drums commit the full contents to a single production window. Therefore, batch sizes need to align with drum capacity, or remaining product must be incorporated into the same production run. For diced tomatoes in juice, a 55-gallon drum holds approximately 475 pounds. For tomato paste, approximately 540 pounds. For ground tomatoes in puree, approximately 470 pounds. Additional pack size and weight details are available on our frequently asked questions page.
Sanitation procedures expand as well. Pumps, shovels, dumpers, and the area around the drum opening all require documented food safety protocols. For manufacturers already operating under GFSI-certified frameworks, bulk aseptic drum handling integrates into existing sanitation programs without difficulty. For manufacturers earlier in their food safety maturity, the conversion is a useful moment to formalize standard operating procedures.
