Five Key Indicators for Choosing Food-Grade Laser Marking Equipment

In the food packaging industry, choosing the right laser marking equipment is critical.The article examines five key factors--safety certification, material compatibility, marking accuracy, machine durability, and after-sales service--and provides tips for selecting food-grade laser equipment.

Why should food safety begin with equipment?

The marks on food packaging are directly related to consumer health. If the production date or batch number is unclear or defaced, there could be a safety problem.As a process that directly contacts packaging, laser marking's first line of defense is compliance with standards.

Look for safety certifications, and don't step on a land mine.

They need to understand the standards for both domestic and foreign certification.

Food-grade equipment must be certified by the US FDA or the EU CE. In Taiwan, it must meet GB 4806 food safety standards.Some manufacturers try to pass off industrial-grade equipment as food-grade. Be sure to ask for the original certificate, and don't just look at the brochure.

Compatibility testing with materials is indispensable.

Different packaging materials (such as plastic, glass, and metal) react differently to laser wavelengths.A responsible company will provide free sample testing. You can bring your own packaging materials to test the effect, and observe whether it causes burns or produces an unpleasant odor.

How do you balance speed and accuracy?

If the label is too shallow it will be easy to remove, and if it is too deep it might penetrate the packaging.We suggest checking the lines with a magnifying glass to see if they are clear and if the edges are sharp.If you need a high-speed production line, select a fiber laser. If you want to do fine detail on small batches, select an ultraviolet laser. Don't save money by buying the wrong type.

The lifespan of equipment also hides hidden costs.

The life of a laser directly affects maintenance costs.Fiber lasers can be used for 100,000 hours or more, while CO2 lasers last around 50,000 hours.When purchasing, make sure to ask about the warranty period for the core components. Don't get fooled by the vague "whole machine warranty" sales pitch.

Post-sales response is more important than price.

What happens if the production line breaks down in the middle of the night?The contract stipulates that the contractor respond within four hours and arrive at the site within 24 hours. When inspecting the site, they also take a look at the maintenance workshop to see if it's clean.
