Laser coding solutions for the Food industrial
Laser coding is widely used on food packaging materials such as glass, aluminum, paperboard, and pigmented or additive‑containing plastics, providing permanent, ink‑free marks like batch numbers and best‑before dates. It delivers high contrast on cans, cartons, thermoformed trays, and lids, and works exceptionally well on metal and coated surfaces. However, clear or non‑absorbing films (e.g., transparent PE shrink wrap) are generally unsuitable unless specially treated, making material compatibility a key consideration.
