High-Volume Tray Packing Jobs
Primary product grouping and shrink wrapping
This tray provides a clean, rigid base for grouping heavy or rigid primary containers like glass jars, bottles, and canned goods. Once formed and loaded, the open top allows for direct product visibility, making it a strong foundation for shrink-wrapping or overwrapping before retail display.
Base component for telescopic boxes
When paired with a matching lid, this tray serves as the bottom half of a rigid two-piece box. The glued corners provide vertical support for the lid, though the exact board grade should be matched to the expected top load.
Bakery and confectionery trays
For baked goods or multipack sweets, the open-top format allows consumers to see the product. The tray is typically formed, loaded, and then sealed in a clear overwrap to maintain freshness.
High-volume retail multipacks
For club stores or retail shelves where products are displayed directly in their transit tray, the unwebbed glued corners offer a clean appearance without the bulky fold-over panels seen in friction-locked alternatives.
Production Environments
Automated packing facilities
This package fits facilities that have invested in automated tray forming equipment. By shifting the gluing process to the packing line, operations benefit from efficient inbound logistics and rapid assembly.
Beverage and preserve producers
Operations packing heavy glass jars or bottles often use this tray to keep items grouped securely. The glued corners hold the tray shape firmly while the product moves through shrink-wrapping tunnels.
High-volume retail distribution
Brands shipping large quantities of multipacks to club stores use this tray to balance material efficiency with a clean retail presentation, avoiding the extra board used in double-wall locking trays.
When to Consider Collapsible or Self-Locking Trays
Manual fulfillment or short runs
If your packing team sets up boxes by hand, this tray involves manually applying wet glue or double-sided tape to four corners, which slows down the line. Consider an unglued self-locking tray or a pre-glued collapsible tray that snaps open.
Heavy stacking without a lid
Because the walls are single-ply, vertical compression strength relies entirely on the four glued corners. If the tray will bear heavy top loads without a supporting lid or master shipper, a double-wall tray or a design with reinforced corners may be worth comparing.
Need for a fully closed box
If the product needs protection from dust or light without relying on a separate lid or overwrap, consider a tray with an integrated complete flap cover.
Machine Tolerances and Board Choices
Tray former compatibility
The exact make and model of your tray forming equipment dictates the blank size limits, hopper feed orientation, and whether the machine uses hot melt or cold glue. These details determine the necessary tab dimensions and board coating.
Board thickness and fold clearance
Moving from a thin folding carton board to a thicker micro-flute corrugated changes how the flaps fold. The template should be adjusted with specific step creases to prevent the material from binding during the plunger stroke.
Adhesive application method
Whether the packing line uses hot melt nozzles or cold glue affects the required compression time and the choice of board finish, as heavily coated boards may resist certain adhesives.
Grain direction for hopper feeding
The grain direction of the board usually needs to run parallel to the longest fold to prevent bowing, but this should be verified against the specific feeding requirements of your tray former.
Adjusting for the Tray Former
Glue tab angles
The angles and clearances of the four corner glue tabs can be tuned to match the specific forming cavity of your equipment, ensuring smooth folding without interference.
Wall height and lateral support
The height of the side and end walls can be adjusted independently of the base footprint to expose more of the primary product or to provide deeper lateral support for taller items.
Double-wall reinforcements
If one or more sides need extra rigidity for display headers or handling, fold-over panels can be added to create double walls on specific sides.
Board and packing details
Flat delivery and warehouse space
Because these blanks are not pre-glued or folded by the converter, they ship completely flat. This maximizes the number of trays per pallet, reducing inbound freight costs and warehouse space requirements compared to knocked-down-flat glued trays.
Tray Variants
Double-wall reinforcements
If one or more sides need extra rigidity for display headers or handling, fold-over panels can be added to create double walls.
Additional notes
Board grain and hopper feeding
The grain direction of the board usually needs to run parallel to the longest fold to prevent bowing, but this should be verified against the specific feeding requirements of your tray former.
FAQs
Production and Setup
Can this tray be run on a standard folder-gluer?
Because it lacks diagonal corner creases, it does not fold flat after gluing. It is designed to be shipped as a flat blank and erected by a tray former at the final packing location.
Is this tray suitable for hand packing?
Erecting it by hand involves manually applying adhesive or tape to all four corners. If you are packing by hand, a self-locking or pre-glued collapsible tray is usually a faster choice.
Materials and Route
Does this tray work for parcel shipping?
Not on its own. As an open-top, single-wall tray, parcel shipment usually involves a master shipper, a matching telescopic lid, or a rigid overwrap.
What board types make sense for this design?
It is typically cut from folding carton board for clean machine forming and retail graphics. It can be adapted for micro-flute corrugated, but the template's fold clearances should be adjusted to handle the extra thickness.
Inserts and Fit
Can partitions or inserts be added?
Yes. The open rectangular basin easily accepts separate die-cut inserts, cross partitions, or molded trays to separate glass bottles or fragile items.
Production and Setup
What product and machine details matter first?
Knowing the exact make and model of your tray former, the adhesive system it uses, and the weight of the products being grouped will help determine the correct board grade and tab clearances.
Materials and Route
How does this tray ship to the packing facility?
It ships as a completely flat, unglued blank. This maximizes the number of blanks that fit on a single pallet, reducing inbound freight space compared to pre-glued trays.
Inserts and Fit
Can the wall heights be adjusted?
Yes, the side and end walls can be sized to expose more of the primary product or to provide deeper lateral support for taller items.
