How to Order in 4 Simple Steps
From precise measurements to premium printing — everything you need to get your tuck end box exactly right.
1
Step 01
Measure Your Product
A tuck end box is a single-piece folding carton. Tuck flaps on both the top and bottom fold in to close the box securely. Measure internal Length, Width, and Height.
✦ Add 3–5 mm per side so your product fits comfortably and the tuck flaps close flat.
2
Step 02
Choose Paper Stock
Tuck end boxes are made from a single sheet of coated paperboard — die-cut, scored, and folded. They ship flat and assemble in seconds.
✦ 350 gsm gives the best balance of rigidity, clean fold lines, and print quality.
3
Step 03
Design Your Artwork
One flat dieline covers all panels: front, back, two sides, top and bottom tuck flaps, and a glue tab. All artwork prints in one pass.
✦ Keep logos 10 mm from fold lines. Avoid placing key art near the glue tab or tuck edges.
4
Step 04
Pick Your Finish
Choose Matte or Gloss lamination. Add Spot UV, Foil Stamping, or Soft-Touch coating to make your brand pop on the front panel and tuck flaps.
✦ Best combo: Gloss lamination + Spot UV on the logo for a retail-ready look.

Structure & Materials
1. What is a corrugated reverse tuck with lock-in mechanism?
A corrugated reverse tuck with lock-in mechanism is a single-piece folding carton made from corrugated board with reverse tuck flaps (closing from opposite directions) plus additional locking tabs that interlock to prevent the box from accidentally opening. This design combines the security of reverse tuck with extra mechanical locking for superior closure strength.
✅ Commonly used for ecommerce shipping, heavier retail products, subscription boxes, and products requiring extra security during transit
2. How does the lock-in mechanism work?
The lock-in mechanism features interlocking tabs that secure the closure:
- Primary reverse tuck flaps fold from opposite directions
- Lock tabs insert through die-cut slots or slits
- Tabs bend or hook to prevent withdrawal
- Creates a mechanical lock requiring intentional opening
✅ The lock-in design prevents accidental opening during shipping and handling
✅ More secure than standard reverse tuck, no tape required
3. What corrugated materials are available?
Multiple corrugated board options are available:
- E-Flute: 1/16" thick – lightweight, ideal for retail and small products
- B-Flute: 1/8" thick – strong, excellent crush resistance
- C-Flute: 3/16" thick – superior stacking strength for shipping
- White or kraft liner: Available for printing or natural appearance
✅ Flute selection depends on product weight, shipping requirements, and cushioning needs
4. Are these boxes custom sized?
Yes. Every box is custom-made to your product and shipping requirements.
- Length, width, and height tailored to product dimensions
- Lock tab placement optimized for closure strength
- Flute direction selected for maximum strength
- Tuck flap depths engineered for secure closure
✅ Custom sizing ensures product protection and secure lock-in mechanism function
5. Do these boxes ship flat?
Yes. Corrugated reverse tuck boxes with lock-in mechanisms are delivered flat (knocked down).
✅ Flat shipping minimizes freight costs and storage space
✅ Assembly is straightforward – fold, tuck, and lock
✅ No tape required due to lock-in mechanism
6. Are corrugated boxes eco-friendly?
Yes. Corrugated boxes are highly sustainable:
- 100% recyclable and biodegradable
- Made from 70-100% recycled content
- FSC-certified options available
- Water-based inks and adhesives
- No tape needed with lock-in mechanism
✅ Corrugated is one of the most recycled packaging materials globally
Printing, Finishing, & Customization
1. Can corrugated boxes be printed?
Yes. Multiple printing options are available:
- Flexographic printing: Cost-effective for large runs, 1-4 colors
- Digital printing: Full color CMYK, ideal for smaller runs
- Litho-lamination: High-quality offset printing laminated to corrugated
- Outside only or inside/outside printing
✅ Print quality depends on liner type and printing method
2. What finishes are available for corrugated?
Finishing options for corrugated boxes include:
- Matte or gloss varnish (water-based)
- Aqueous coating for moisture resistance
- UV coating for enhanced graphics
- Wax coating for moisture protection
✅ Finishes protect graphics during shipping and handling
3. Can I add special features?
Yes. Common features for corrugated boxes include:
- Die-cut handles for easy carrying
- Perforated tear strips for easy opening

✅ Features can be combined with the lock-in mechanism
4. Can embellishments be added to corrugated?
Yes, though options differ from paperboard:
- Foil stamping (best on litho-laminated boxes)
- Spot UV (requires smooth white liner)
- Embossing or debossing (creates texture on flute)
- Custom die-cut shapes and patterns
✅ Litho-lamination provides the best surface for premium embellishments
5. Can the lock-in mechanism be customized?
Yes. Lock-in mechanisms can be tailored:
- Single or multiple lock tabs for extra security
- Lock tab shapes optimized for your product weight
- Placement adjusted for ease of opening vs security
- Perforated tabs for easier opening if desired
✅ Lock strength is engineered based on product weight and shipping conditions
