Description

High-Speed Assembly: Pre-Glued Four Corner Trays & Display Boxes

A Four Corner Box (also referred to as a 4 corner beer tray, lock corner tray, or infold / outfold four corner box) is engineered for operations where rapid packaging assembly is critical to daily throughput. Built with four pre-glued collapsible corners, these boxes ship completely flat but pop open into full-depth rigid trays with a single swift motion.

At XCustomBox, our custom four corner boxes eliminate the tedious, time-consuming folding and taping required by traditional die-cut mailers. Whether deployed in busy commercial bakeries packing delicate cakes or fulfillment centers boxing luxury apparel and cosmetic gift sets, our four corner trays provide unmatched structural speed and durability.

Custom Corrugated & Paperboard 4-Corner Cake & Bakery Boxes

Bakery chefs and catering operations face unique packaging challenges: delicate frostings, towering cake layers, and grease-prone pastries must remain pristine during transit. Our custom 4 corner cake boxes feature moisture-barrier food-grade coatings and fold-down side walls that make loading and removing heavy cakes seamless without damaging delicate perimeter decor.

Available in both rigid SBS paperboard for gourmet patisseries and heavy-duty E-flute / B-flute corrugated cardboard for multi-tiered wedding cakes, our four corner bakery boxes resist grease penetration and hold their shape under substantial stacking pressure.

Four Corner Boxes with Display Lids & Two-Piece Telescope Sets

Depending on your product requirements, XCustomBox engineers four corner packaging in multiple functional configurations:

  • Four Corner Tray with Attached Fold-Over Lid: A unified one-piece box featuring an integrated top lid and tuck flap, ideal for retail gift kits, pharmaceutical samples, and electronics.
  • Two-Piece Telescope Tray & Lid: Separate top and bottom four corner trays that nest over one another, creating an opulent unboxing experience for luxury garments, shoes, and jewelry.
  • Four Corner Display Trays with Header: Open-top counter display units (CDUs) with an extended rear pop-up billboard designed for point-of-purchase impulse retail counters.
  • Lock-Corner Glueless Trays: Tab-and-slot corner designs that fold together without adhesive, offering maximum sustainability and ultra-flat bulk shipping.

Frequently Asked Questions About Four Corner Boxes

How does a pre-glued four corner box assemble?

Pre-glued four corner boxes arrive flat with the four diagonal corners already bonded in our factory using high-tensile industrial glue. To erect the box, you simply squeeze the opposing diagonal corners together. The box walls snap vertically into place instantly, forming a rigid four-walled tray in less than two seconds.

Can four corner boxes hold heavy items like glass jars or metal components?

Yes. When produced with E-flute or B-flute corrugated cardboard, four corner boxes provide exceptional compressive strength and burst resistance, easily handling heavy hardware, glass food containers, candle jars, and industrial components.

Are these boxes suitable for direct food and pastry contact?

Yes. We offer FDA-compliant food-grade paperboard and grease-resistant aqueous coatings that prevent butter, cooking oils, and sugar glazes from soaking into the fibers or creating exterior smudges.

Can I print branding on both the interior and exterior of the tray?

Absolutely. We offer dual-side (inside and outside) full-color offset printing. You can showcase bold brand graphics on the exterior and print custom thank-you messages, patterns, or instructional graphics across the interior floor.

What is the lead time for custom four corner boxes?

Standard turnaround is 8 to 10 business days from the moment your digital artwork proof is approved. We provide free doorstep shipping across the contiguous United States.
