MOBA and SANOVO Egg Carton Line Trial Checklist

Use this checklist before moving custom printed corrugated egg cartons from samples into bulk production on automated packing lines.

Plan line validationRequest samples

Step 1

Before samples arrive

  • Document machine brand, model, line speed, carton feed setup, closure setup, and case-pack method.
  • Record current carton material, carton count, egg sizes, storage humidity, and known handling issues.
  • Define pass/fail criteria before the trial so subjective impressions do not decide the result.

Step 2

During trial

  • Observe denesting consistency, double-picks, jams, closure behavior, tab alignment, and lid recovery.
  • Check cavity fit for target egg sizes, filled-carton stacking, case-pack handling, and operator feedback.
  • Run enough cartons to see repeat behavior, not only the first successful samples.

Step 3

After trial

  • Record issues with photos, approximate frequency, machine settings, humidity, and speed.
  • Separate carton-design issues from machine-setting issues before requesting changes.
  • Confirm whether another sample run is needed before committing to bulk or container-volume production.

Buyer answers

Line-trial checklist FAQ

Question

Does Evolo guarantee every carton works on every line?

No. Evolo supports validation workflows. Buyers should test with their actual line model, speed, egg sizes, and operating conditions before scale.

Question

Can line validation happen before final artwork?

Yes. Structural sample and fit review can happen before final artwork, while final print samples can confirm finish and brand execution.

Question

What line information should buyers share first?

Share machine brand, model, line speed, current carton type, target carton format, egg sizes, and any denesting, closure, or stacking issues.
