Use this checklist before moving custom printed corrugated egg cartons from samples into bulk production on automated packing lines.
Step 1
Step 2
Step 3
Define the exposure method before comparing results so each exact carton specification and identified sample lot follows the same buyer-owned protocol.
Step 4
Step 5
Use the approved specification and physical reference sample to decide whether a later production change needs renewed review.
Worksheet
| Validation item | What to record |
|---|---|
| Denesting | Separation consistency, double-picks, jams, feed angle, and operator intervention. |
| Closure | Lid alignment, tab lock, rebound, missed closures, and speed sensitivity. |
| Stacking | Filled-carton stability, case-pack behavior, compression marks, and storage conditions. |
| Egg fit | Target egg sizes, cavity movement, breakage concern, and XL/jumbo/duck fit where relevant. |
| Environmental conditioning | Exact specification and sample lot; pack-house and storage temperature/relative humidity; exposure duration and transitions; empty or filled state; filled-stack height and dwell time; case/crate route; target line speed; denesting, closure, deformation, compression, and breakage observations; buyer-defined pass/fail criteria; and sign-off owner. |
| Line speed | Actual speed tested, speed changes, issue frequency, and practical operator notes. |
| Repeat-order revalidation | Approved specification and physical reference sample, notified production or logistics changes, buyer-defined tolerances, and the buyer-owned decision on new samples, line checks, document review, retailer review, testing, or release. |
Buyer answers
Question
No. Evolo supports validation workflows. Buyers should test with their actual line model, speed, egg sizes, and operating conditions before scale.
Question
Yes. Structural sample and fit review can happen before final artwork, while final print samples can confirm finish and brand execution.
Question
Share machine brand, model, line speed, current carton type, target carton format, egg sizes, and any denesting, closure, or stacking issues.
