Meta Description: Learn the difference between a pre-production sample and a production sample and how each helps buyers control custom packaging quality.

What Is a Pre-Production Sample?

A pre-production sample, often abbreviated as PPS, is produced before bulk manufacturing.

Its purpose is to confirm what the factory is expected to manufacture.

A PPS can establish standards for:

· Material

· Size

· Printing

· Color

· Handles

· Accessories

· Sewing

· Construction

· Finishing

Why Physical PPS Approval Matters

Photographs and videos are useful for communication, but they cannot fully communicate:

· Material hand-feel

· Thickness

· Handle comfort

· Zipper performance

· Structural stiffness

· Exact dimensions

· Real-world product fit

For technically important projects, a physical PPS provides stronger verification.

Final Artwork Approval Is Separate

Approving the physical sample does not necessarily mean approving every artwork file.

The buyer should clearly approve both:

Physical PPS

and

Final production artwork

when both are required.

This prevents production from accidentally using an older artwork version.

Written Approval

Important approvals should be recorded in writing.

A clear production condition can state:

Bulk production will begin only after the buyer provides written approval of both the physical pre-production sample and final production artwork.

This creates a clear production checkpoint.

What Is a Production Sample?

A production sample is selected from actual mass production.

It helps answer a different question:

Does the bulk production match the approved PPS?

The PPS defines the intended standard.

The production sample verifies execution.

Golden Sample

Some buyers refer to the final approved reference as the “golden sample.”

Both buyer and factory can retain matching samples.

During QC, production goods are compared against this approved reference.

What Should Be Compared?

Inspect:

· Dimensions

· Material

· Color

· Logo

· Printing position

· Handles

· Stitching

· Zippers

· Reinforcement

· Accessories

· Overall appearance

Functional tests should also be repeated where relevant.

When Is a Revised PPS Necessary?

Consider making a new physical sample when changing:

· Material

· Bag dimensions

· Major construction

· Handle design

· Zipper

· Structural features

· Important printing requirements

Minor artwork corrections may sometimes be confirmed digitally, depending on the project.

PPS and Third-Party Inspection

The approved PPS can also support independent inspection.

Inspectors can compare production goods against:

· Specification sheet

· Approved artwork

· Physical reference sample

· Defined tolerances

The inspection standard should be established before the inspection occurs.

Keep Samples for Repeat Orders

For recurring orders, retaining an approved sample can improve consistency.

However, materials and production conditions can change over time, so critical specifications should also remain documented in writing.

FAQ

Is PPS the same as a prototype?
They can be similar, but PPS generally refers to the sample intended to represent the approved standard before mass production.

Can I approve a PPS through photos?
That depends on the project and buyer's risk tolerance. Physical inspection provides more information.

What happens after PPS approval?
Once all required approvals and commercial conditions are completed, the supplier can proceed according to the agreed production schedule.

Should the factory keep an approved sample?
Yes, particularly for repeat programs and quality-control comparison.

Sample-to-Production Quality Control

Soma Package Ltd. supports physical sample development, written specification confirmation, production quality control and third-party inspection coordination.

For projects requiring formal PPS approval, please state the approval procedure when requesting your quotation so it can be incorporated into the production plan.
