How this structure works
The FEFCO 0215 – Tuck Top Manual Lock Bottom Box is generated as a snap lock carton mechanism. Packeri rebuilds panel spans, rule junctions, flap depths, root relief and receiver relationships from the selected dimensions and measured material caliper.
Best uses
Moderate-weight retail products using a mechanical base.
Materials and allowances
Corrugated and microflute constructions need flute-specific score allowance, slot width, compression and manufacturer-joint calibration.
Engineering notes
- CUT and CREASE geometry remain separate production layers.
- Body folds terminate before knife intersections where the mechanism requires root relief.
- Glue appears as guidance text and metadata, never as a misleading shaded production polygon.
- Receiver slots, tongues, dust flaps and closure members respond to material thickness.
Limitations
Software geometry cannot certify tooling, folding equipment, adhesive pattern, packed-product loads, compression, board batch or print-finishing behavior. Prototype and converter approval are required before mass production.
Frequently asked questions
Are the dimensions internal or external?
The generator supports a dimension basis and reports compensated score spans. Final converter allowances override generic defaults.
Can I export production files?
Active Pro accounts can export clean SVG, PDF and DXF from the same normalized geometry used for preview.
Does this replace a packaging converter?
No. It accelerates structure development and communication. Tooling and mass production still require material-specific converter approval.
