The EVF92007 is a flat, uncreased elliptical pad designed to act as an internal component for tube-style or oval packaging. It is delivered flat and ready to be dropped into a primary container.
Because it is a single static panel, it requires no folding or assembly. It is most commonly used as a base stiffener to reinforce the bottom of a bag or carton, a layer divider between products, or a structural insert.
Base reinforcement for flexible or lightweight oval containers
When packing heavy items in flexible bags or lightweight oval cartons, an elliptical pad dropped into the bottom distributes the weight and prevents the base from bowing or tearing.
Layer separation inside oval master cartons
Used to separate layers of bottles, jars, or cosmetics within a larger oval master carton, preventing product-to-product contact and scuffing during transit.
Top-layer presentation inserts for unboxing
A printed elliptical pad can be placed at the top of a tube or oval box to provide branding, instructions, or a clean visual presentation when the customer opens the package.
Structural end caps for rigid elliptical tubes
Inserted at the top or bottom of a rigid oval tube to close the ends, often held in place by friction, an outer wrap, or a rolled edge.
Industry and Product Fit
Premium cosmetics and personal care tubes
Often used inside premium oval tubes or set-up boxes to separate products or provide a branded top layer.
Heavy bottle packaging in presentation tubes
Provides base reinforcement for tall, heavy bottles packed in elliptical presentation tubes.
Confectionery and specialty food tins
Acts as a clean, food-safe divider between layers of chocolates or biscuits inside oval tins or cartons.
When to Consider a Different Pad Shape
When the outer container is rectangular
If your primary package is a standard square or rectangular box, a standard rectangular pad will fit better and nest more efficiently during manufacturing, reducing material waste.
When the outer container is a perfect cylinder
If the primary package is a round tube rather than an oval, a circular die-cut pad provides the correct uniform clearance on all sides.
Key Decisions for Elliptical Inserts
Board thickness and load support
The required thickness depends on the job. A lightweight folding boxboard works well for printed layer dividers, while a thicker corrugated or rigid grey board is necessary if the pad must support heavy vertical loads as a base stiffener.
Sizing for friction fit or drop-in clearance
The length and width of the pad must be sized slightly smaller than the internal dimensions of the outer container to allow for easy insertion, but tight enough to prevent lateral shifting.
Surface porosity for automated pick-and-place
If the pads will be placed by automated suction-cup robots, the board surface must be non-porous enough to allow the suction cups to grip reliably.
Moisture resistance for chilled or humid environments
If the pad will be used in refrigerated supply chains or exposed to moisture, specifying a coated board or moisture-resistant treatment prevents the pad from warping or losing stiffness.
Sizing and Material Adjustments
Independent axis scaling for custom ovals
The major axis (length) and minor axis (width) can be scaled independently to match the exact profile of your oval container.
Print surfaces for visible presentation layers
The pad can be left unprinted for hidden structural use, or printed on one or both sides with varnishes or coatings for visible presentation layers.
Internal cutouts for product seating
Custom holes or shapes can be die-cut into the center of the pad to hold specific items, such as a bottle neck or a cosmetic jar, keeping them centered within the outer tube.
Packing details
Sheet layout and material yield for curved cuts
Unlike rectangular pads that can share straight cutting lines with zero waste between them, elliptical shapes leave offcuts when nested on a master sheet. This means the material yield is lower, requiring more raw board per piece.
Additional notes
Sizing tolerances for drop-in versus friction fit
When sizing the pad, ensure the length and width account for the thickness of the outer container's walls. A pad that is too tight will bow when inserted, while one that is too loose will shift during transit.

FAQs
How is the elliptical pad secured in place?
The pad relies entirely on the outer container. It is typically held in place by friction against the inner walls or by resting flat against the base of the primary package.
Can this pad be inserted automatically?
Yes, flat pads are well-suited for automated pick-and-place machinery, provided the board material is compatible with the suction or gripping mechanism used on the packing line.
What materials can be used for this pad?
It can be cut from almost any flat material, including lightweight folding boxboard for dividers, corrugated board for heavy-duty base pads, or rigid grey board for premium tube bases.
How does the elliptical shape affect material efficiency?
Because ellipses cannot share straight cutting lines on a master sheet, they generate more interstitial waste than rectangles. This lower nesting efficiency means more raw board is required per piece compared to a straight-cut rectangle.
Can the pad be printed?
Yes, since it is a flat sheet, it can easily be printed on one or both sides before die-cutting. This is common when the pad is used as a visible top insert or lid.
Can cutouts or holes be added to the pad?
Yes, internal cutouts can be added to hold specific products, though this requires additional stripping during manufacturing and may reduce the overall stiffness of the pad.
How do I determine the correct length and width for my container?
The pad's major and minor axes should be sized slightly smaller than the internal dimensions of your outer container. The exact clearance depends on whether you need a tight friction fit or a loose drop-in fit.
Does the pad require any folding or assembly?
No, the elliptical pad is a single, flat piece of board with no creases. It is delivered flat and used exactly as it is.
Whether you need a structural base for a heavy bottle or a printed divider for a cosmetics tube, the elliptical pad provides a clean, exact fit for oval packaging.
