When sourcing standard conical cups for drinks, snacks, or dry goods, the EVF99090 provides a classic two-piece paperboard construction. It consists of a curved main body that rolls into a cone and a separate circular bottom disk.
Unlike flat-packing cartons, this cup is typically processed on dedicated rotary cup-forming equipment that rolls the body, seals the side seam, inserts the base, and curls the top and bottom rims.
When produced with barrier-coated board and heat-sealed seams, this cup can hold hot or cold liquids. The top extension curls into a smooth drinking lip, while the bottom extension crimps around the base disk to help prevent leaks.
Dry snacks and concessions
For popcorn, fries, or dry promotional items, the cup can often be produced using standard folding boxboard without specialized liquid barriers, though it still relies on automated forming.
Promotional event containers
The continuous curved surface provides a strong billboard for branded giveaways or event marketing, often utilizing high-quality print finishes on the outer wall.
Dry ingredient portioning
In food service preparation or sampling environments, smaller versions of this cup offer a stable, open-top shape for measuring and staging dry goods.
Beverage and food service contexts
Large-scale food service
Because these cups are usually formed on dedicated rotary equipment, they are well-suited for large repeat programs. The finished cups ship nested in sleeves, which changes warehousing and dispenser planning compared to flat-packed cartons.
Event marketing and campaigns
Brands using these for short-term promotions need to balance the visual impact of the curved print surface against the production scale often associated with cup-forming machinery.
Specialty coffee and beverage brands
For hot or cold drinks, the choice of board coating and side-seam sealing method becomes a primary focus to ensure the cup performs well under temperature and moisture stress.
When to consider sleeves or flat-folding cartons
Hand-packed or short-run dry goods
If you need a container that can be assembled by hand or run on straight-line gluing equipment, a crash-lock or snap-bottom folding carton is often a better fit. Two-piece cups are generally not practical for manual assembly at scale.
Wraps and bottomless sleeves
If the goal is simply to insulate an existing container or wrap a solid product, a single-piece conical sleeve without a bottom disk reduces material and simplifies the production path.
Machine alignment, coating, and production choices
Matching existing machine sizes
The top diameter, bottom diameter, and overall height should align with the forming equipment at the production facility. Custom sizes that do not match existing machine profiles may require a longer preparation path.
Barrier coatings and sealing
The product guides the board choice. Liquids often need specific barrier coatings (like PE or PLA) and heat-sealing for the side seam, while dry goods might use standard cold glue and uncoated or lightly coated board.
Determining the top curl allowance
The template includes a top extension that rolls into the drinking lip. This allowance should be calibrated to the board thickness and the specific curling stations on the forming equipment.
Planning for nested shipping volume
Because the bottom is permanently crimped and the body is rolled, finished cups are shipped nested in stacks. This takes up more volumetric shipping and storage space than flat-packed cartons.
Adjusting cup proportions and rims
Top extension for the drinking lip
The top extension parameter controls the extra material needed to roll a smooth top rim. Adjusting this changes how thick or tight the final curl becomes.
Bottom extension for the base crimp
The bottom extension parameter provides the material that folds inward and upward to capture the separate bottom disk. It should be sized correctly to help ensure a secure seal without jamming the crimping station.
Glue flap width and bevels
The side seam overlap can be adjusted in width and angle to accommodate different sealing methods, whether using cold glue for dry goods or heat sealing for coated boards.
Packing details
Grain direction for smooth rolling
The paperboard grain should run perpendicular to the cup's height. This allows the main body blank to roll smoothly into a cone without cracking or forming a faceted, polygonal shape.
Additional notes
Matching existing machine sizes
Because cup forming relies on rigid metal forms, even small changes to the top or bottom diameter can require a completely new production path.

FAQs
Can this cup be assembled by hand?
Generally, no. This two-piece design relies on specialized rotary cup-forming machinery to roll the cone, insert the bottom disk, and curl the rims. It is not practical for manual assembly at scale.
Can this be run on straight-line gluing equipment?
No. Because it is a rolled cone rather than a flat-folding shape, it is not designed for processing on straight-line gluing equipment.
Do these cups ship flat?
No. Once the bottom is crimped and the body is rolled, the finished cups are shipped nested in stacks. This takes up more volumetric shipping and storage space than flat-packed cartons.
Is this cup automatically safe for liquids?
The template provides the shape, but liquid safety depends on the material. Beverage cups usually need barrier-coated boards (like PE or PLA) and heat-sealed side seams to hold moisture.
Can I freely adjust the height and diameters?
While the CAD template can generate any size, the physical cup should match the exact metal forms on the converter's equipment. Custom dimensions often involve a custom production path.
Why is grain direction important for this package?
The main body should roll smoothly into a cone. If the paperboard grain runs the wrong way, the board resists rolling and can crack or form flat, faceted sides instead of a smooth circle.
What are the top and bottom extensions used for?
The top extension provides the extra material needed to roll a smooth drinking lip. The bottom extension is the material that folds inward and upward to capture and seal the separate bottom disk.
How is the side seam secured?
The main body includes a glue flap that overlaps the opposite edge. Depending on the board coating and end use, this seam is secured using either cold glue or heat sealing during the rolling process.
Review your product's moisture content and available machine sizes before finalizing the cup dimensions.
