Coding & Marking

Choose Between Inkjet and Laser Coding

Two coding technologies cover most beverage and packaging marking requirements. The right choice is decided by the packaging surface, the marking content and whether the code has to be permanent.

Inkjet Date Coding Machine

Variable DateBatch CodeCartons · Labels

Inkjet coding for variable production information such as dates, batch codes and other confirmed text on beverage and liquid-packaging lines.

Recommended starting point

Inkjet Date Coding Machine

For variable date and batch codes on cartons, labels and film, start with an inkjet date coding machine and confirm the marking content, surface and line speed.

Coding Technology

Different Packaging Surfaces Need Different Coding Methods.

Coding method is not only a machine choice. It affects whether the code stays legible, what consumables the line needs and how the coder fits into the existing production flow.

Inkjet Coding

Suitable For Cartons, Labels & Film

Inkjet coding prints variable information such as dates and batch codes onto the packaging surface, and can be changed from run to run.

Inkjet Date Coding Machine
Laser Coding

Suitable For Permanent Marking

Laser coding marks the material itself without contact and without ink or solvent, for codes that have to remain permanent.

Laser Coding Machine
Decided by Substrate

Suitable For Mixed Packaging Ranges

The packaging material determines which coding method is applicable. Cartons, labels, film, PET and glass do not all accept the same method.

Why SinoPAK

Why SinoPAK Coding Equipment?

For overseas buyers, a coding machine needs to fit the packaging surface, the marking content, the line speed and the rest of the production flow. SinoPAK supports both machine selection and line integration.

Surface Fit

Method chosen around the packaging

Coding method is selected around the packaging material, the marking content and the required durability.

Speed

Matched to line output

Coding equipment is matched to the line speed so marking does not become the bottleneck.

Line

Line integration

Coding equipment can connect with filling, labeling, packing and conveying systems.

Support

Technical & after-sales support

SinoPAK supports communication from selection through installation, commissioning and production support.

Coding & Marking FAQ

Choosing a Coding & Marking Machine?

Clear answers for buyers comparing inkjet and laser coding and planning the next step with SinoPAK.

It depends mainly on the packaging surface and whether the code has to be permanent. Inkjet coding is used for variable information such as dates and batch codes on cartons, labels and film. Laser coding marks without contact and without consumables, for permanent marking on compatible materials. Share your packaging material and marking content and SinoPAK can confirm which method applies.
Typically production and expiry dates, batch or lot codes, and other confirmed production text. The exact content depends on the coding method, the packaging surface and the available marking area.
No. Laser coding marks the material itself and does not use ink or solvent consumables. Inkjet coding does use ink, and may also require solvent and cleaning agents depending on the system.
Yes. Integration depends on the conveyor, line speed, packaging format and available space at the coding position. SinoPAK can review your existing line information and recommend how a coding machine can be added to the current setup.
Legibility depends on the packaging surface and the coding method. Some surfaces accept ink readily, others hold a laser mark better. A packaging sample or clear photo helps confirm the applicable method before the machine is specified.
Please share the packaging material, the marking content, the required durability, the line speed and whether this is a new project or an existing line upgrade. Photos of the packaging and the coding position also help.
