Material evaluation
Four checks before approving the material
Fibre and appearance
Review recycled content, shade, formation, specks and batch variation against the intended visual and sustainability requirement.
Colour target
Use an approved physical reference, Pantone target or measurable tolerance and define the viewing condition for approval.
Stiffness and forming
Evaluate folding, scoring, opening force and load support on the intended structure rather than judging material only by hand feel.
Claim evidence
Tie recycled, biodegradable, compostable or reduced-plastic statements to a defined product, method and supporting document.
Execution method
Four actions from RFQ to production
Define the application
Start from protection, forming, print, appearance and distribution needs.
Compare physical samples
Review representative material under agreed lighting and handling conditions.
Run process trials
Test printing, creasing, gluing, finishing and packing on the proposed build-up.
Freeze an approved specification
Record supplier, grade, weight, thickness, colour and permitted substitution rules.
FAQ
Questions buyers often ask
When is kraft paper suitable for custom packaging?
Kraft paper suits natural visual directions and many practical structures, but shade, fibre variation, ink colour, scoring and recycled-content claims need approval.
What should be written in the specification?
At minimum, define Fibre and appearance, Colour target, Stiffness and forming, Claim evidence, 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.
