Packaging material is an effective first filter, but it cannot select the equipment on its own. Film, rigid plastic, cartons, glass, and metal respond differently to ink, heat, and laser energy. Colour, coating, thickness, and surface structure also change the result. Use the table to narrow the options, then validate the final route on the actual package.
Candidate technologies by packaging material
Why the same material category can behave differently
In flexible packaging, the multilayer structure, printed background, and surface treatment affect ink adhesion or laser response. Transparent, white, metallised, and matte films should not be treated as one material.
Laser selection depends on how the material absorbs energy. CO2 lasers often create a surface change on cartons, glass, and selected polymers. UV lasers suit heat-sensitive plastics such as PE and can mark mono film with less risk of piercing. Fiber lasers are mainly used on metal parts and may interact with selected non-metal materials. Confirm the wavelength and process on the actual sample.
Evaluate material and production line together
- Package shape: flat, curved, and irregular surfaces change how a printhead, laser lens, or label applicator is mounted.
- Line speed: a higher speed may require new parameters, print width, and position checks.
- Content: dates, batch data, 2D codes, and logos have different resolution and area requirements.
- Durability: rubbing, cold, water, oil, and tamper resistance affect consumables, laser settings, or process choice.
- Environment and maintenance: fume extraction, cleaning, ribbon, ink, and spare parts belong in the operating assessment.
What to confirm in a sample test
Test with the actual package material, content, line speed, and planned mounting position. Check character integrity, position stability, adhesion after storage and transport, and reliable barcode or 2D-code reading.
Repeat the test if the packaging supplier, colour, coating, or multilayer structure changes. A material table helps narrow the search, but it does not replace physical acceptance.
Exclude clearly unsuitable routes first, then confirm the candidate against line conditions and sample results. This reduces unnecessary comparisons and resolves selection risk before production.
