Rigid boxes / JETDIELINE

Magnetic closure box – inside lining

Lining paper for the inside of the case, smaller by the margin all around; covers the turn-ins and the flap's magnet.

Simplified display model without material thickness, not to scale.

Template ID: rigid.magnetic.cover.lining
Component: Rigid boxes
Current template version: V1
Dieline preview version: V1

This template is a component of a packaging assembly. Match its dimensions to the other parts; lids, bases, wraps and linings serve different purposes.

How it is assembled

Apply glue over the entire lining and center it on the inside of the flat, wrapped case, leaving the margin clear all around; press firmly into the hinges.

Material and grain direction

Grain direction of greyboard and wrapping paper parallel to the x-axis of the blank: the long grooves fold cleanly, and board and paper do not warp against each other during wrapping (check with the rigid box manufacturer).

Test fit, folding and closure on a sample made from the intended material. Confirm material thickness, grain direction and production steps with your printer.

Compare opening and presentation: pillow shapes, bands, drawers or lift-off lids. Plan the fit of contents and inserts and allow clearance between moving parts.

What to consider for this construction

Greyboard thickness

Thickness of the greyboard around which the wrap is folded; the assembly sets it from the greyboard material.

Flap height

Inside height of the front flap from the inside of the lid to the free edge.

Spine allowance

The case spine is taller than the interior by this value; the lid closes with some clearance above the tray.

Overhang

Case overhang beyond the wrapped tray on the left and right.

Lining margin

Distance from the lining to the case edge; the wrap remains visible as a border.

Frequently asked questions

What does the separate inside lining do?

The inside lining covers the case wrap's turn-ins and the magnet in the flap. It is smaller than the case all around; liningMargin starts at 3 mm. Its hinge lines follow the case. Check glue application and movement on the sample so the lining neither strains nor blocks the hinges when closing.

Which magnet size does the example show?

The individual part's starting value is a disc magnet with a 10 mm diameter. The model creates a 10.5-mm recess in the tray's front wall and flap. Diameter and position are construction values. A fitting opening determines neither magnet thickness within the material nor holding force or polarity. Confirm the magnet, flush installation, and adhesive with the rigid box manufacturer carrying out the work.

Why is the tray's magnet height initially 25 mm?

25 mm is the parameter default for the individually calculated tray template and belongs to the existing preview. The assembly overrides it to match the flap; in the starting case, with 22.8 mm. This distinction matters for assembly. Do not transfer independently calculated magnet positions into a finished assembly without checking their alignment.
