Process evaluation
Four controls behind a repeatable finish
Magnet performance
Specify magnet size, polarity, pull force, concealment, safe spacing and closure feel after the box is fully assembled.
Adhesive compatibility
Match adhesive to surface energy, coating, temperature, load and ageing; initial tack alone does not prove long-term performance.
Assembly method
Document folding sequence, glue position, jigs, manual steps and workmanship standards so output is repeatable.
Proof purpose
State whether the proof approves structure, layout, colour direction, material or finished process because one proof rarely confirms everything.
Execution method
Four actions from RFQ to production
Mark a separate finish layer
Use named vector layers for foil, varnish, emboss, cut and other process areas.
Approve on the real substrate
Colour, gloss, relief and adhesion must be checked on the intended material.
Set visible tolerances
Define registration, edges, pinholes, scratches, wrinkles and acceptable variation.
Retain production references
Keep approved samples, process settings and supplier references for repeat orders.
FAQ
Questions buyers often ask
How should magnets be specified in packaging?
Approve magnet polarity, pull force, concealment, spacing, adhesive and closure feel in a fully assembled production-representative sample.
What should be written in the specification?
At minimum, define Magnet performance, Adhesive compatibility, Assembly method, Proof purpose, then link quantity, sample, timing, inspection and the approved revision.
Is a physical sample needed?
A decision involving structure, material, colour, finish, assembly or use performance normally needs a physical sample matched to that question; a screen proof cannot approve everything.
Can the previous standard be reused for a repeat order?
Reuse a controlled standard only when files, material, structure, supply chain and use conditions remain unchanged. Record every change and decide whether resampling or reapproval is required.
