Products that fit the integrated V-slot partition
Vials, ampoules, and sample tubes
The V-shaped slots created by the internal fold naturally hold cylindrical glass or plastic items, separating them without a distinct insert.
Premium pens and precision tools
For high-end stationery or delicate hardware, the integrated divider presents the items in a row when the carton is opened, offering a structured presentation.
Fragile glass dropper bottles
The zig-zag board creates a physical barrier between each bottle, separating them without requiring a separate foam or board insert.
Diagnostic test kit components
When a kit requires a specific sequence of swabs or collection tubes, the individual slots keep components organized and visible to the user.
Retail and clinical channels using single-row presentation
Cosmetics and personal care
Brands packing multi-day treatment ampoules or sets of lip products use this style to organize the presentation and reduce the number of packaging components they need to source.
Pharmaceuticals and diagnostics
Medical and testing kits that require a specific number of vials use this carton to keep components arranged in a predictable row.
Specialty hardware and precision parts
Manufacturers packing cylindrical tools, drill bits, or specialized components use the V-slots to keep edges separated during handling.
When to compare separate inserts or multi-row boxes
Automated packing lines
Because the internal zig-zag partition must be folded into shape before the outer carton wraps around it, this design is typically hand-assembled. If you run an automated line, a standard carton paired with a machine-dropped insert is worth comparing.
Heavy or bulky items
This package relies on folding carton board. If the items are heavy, a corrugated outer box with a separate corrugated partition may be needed for the shipping route.
Board, fit, and closure decisions
Board grade and foldability
The integrated partition requires multiple close-proximity scores that fold back on themselves. The board grade must handle these tight folds without cracking.
Number of slots
Determine how many items need to be packed. The template can be adjusted to add or remove V-shaped slots, which changes the overall length of the flat blank and the final carton.
Product diameter and clearance
The V-slots must be sized to hold the items. Provide the diameter of your product so the zig-zag folds can be calculated.
Closure method
The outer panels that wrap around the partition can be secured with a tuck flap, a glued seam, or a locking tab. This depends on how the end user should open the package.
Modifying the partition and outer wrap
Slot width and depth
The dimensions of the zig-zag folds can be modified to accommodate wider tubes or deeper vials, changing how the product sits in the channel.
Partition height
The height of the internal divider can be adjusted. A taller partition provides more separation for long tubes, while a shorter partition leaves more of the item exposed for removal.
Outer wrap closure style
The final closing panel can be modified to include a friction lock, a simple tuck, or an extended flap for a glued seal.
Board and packing details
Inventory simplification vs. packing labor
The primary commercial advantage of this design is managing a single SKU. You do not need to match inventory levels of outer boxes with separate internal dividers. However, you must weigh this warehouse convenience against the manual labor required to fold the partition.
Multi-row partition alternatives
Double-Row Separator (F60.42.00.00)
A similar integrated design that folds to create two parallel rows of slots, useful for larger sets of items.
Additional notes
Manual folding labor
Factor the time required to fold the internal partition into your packing costs. While you manage fewer components, the assembly is more involved than opening a standard crash-lock box.
Item diameter and clearance
Check the diameter of your product when requesting a sample. The V-slots must be sized to hold the items without crushing them.

FAQs
Assembly and Packing
Can this carton be erected on automated packaging machinery?
Generally, no. The internal zig-zag partition requires specific manual folding to form the slots before the outer panels wrap and close. It is typically used in hand-packing operations.
Product Fit
Can the number of slots be changed?
Yes. The template can be adjusted to include more or fewer folds, changing the number of items the carton holds. This proportionally changes the overall length of the package.
Materials
What type of board is used for this design?
A folding carton board that handles repeated scoring is often used. The board must be flexible enough to handle the tight folds of the partition without cracking.
Design and Print
Can the inside of the partition be printed?
Because the partition is formed by folding a section of the main blank inward, the visible part of the slots typically shows the reverse side of the board unless the material is printed on both sides.
Comparison
Why choose this over a standard box with a separate insert?
This one-piece design simplifies purchasing and inventory by combining two components into one SKU. However, you trade that convenience for a more manual assembly process.
Product Fit
Is this suitable for square or rectangular items?
The zig-zag fold naturally creates V-shaped slots, which cradle cylindrical items like tubes or vials. Square items may not align well in these specific channels.
Assembly and Packing
How are the items loaded into the carton?
The internal zig-zag partition is folded first to create the slots, the items are placed into the V-shaped channels, and then the outer panels are wrapped and closed around them.
Comparison
Can this carton hold heavy glass bottles?
This one-piece folding carton is often used for lightweight items. Heavy glass bottles may require a corrugated outer box with a separate partition depending on the shipping route.
