PET laser marking allows manufacturers to apply dates, batch codes, references and 2D codes directly onto bottles, containers and other PET packaging.
At Macsa id, we select the laser technology and configuration according to the PET grade, bottle thickness, colour, surface finish, required contrast and production speed.
PET laser marking enables manufacturers to add durable, legible codes directly onto PET bottles, containers and rigid packaging without inks, labels or physical contact with the product.
Macsa id develops laser coding solutions for expiry dates, batch numbers, production data, barcodes, QR codes and DataMatrix codes. The right result depends on the PET grade, wall thickness, colour, additives, packaging shape and required line speed.
PET is widely used for beverage bottles, food containers, personal care packaging and other consumer products. Laser coding can apply fixed or variable information directly onto the pack to support product identification and traceability throughout production and distribution.
Typical PET coding applications include:
Depending on the material and laser configuration, the mark may create a controlled frosted or surface-change effect. The final appearance and code quality should always be validated on the real pack.
The laser creates the code directly on the PET surface. This removes the need for ink, cartridges, ribbons and solvents, simplifying consumable handling on the production line.
Laser coding can create dates, batch numbers, text, barcodes and 2D codes with the contrast and definition required for the application. When code readability is critical, the marking process can be combined with verification systems such as Integra Vision.
Macsa id systems can be integrated into automated production lines for coding bottles and containers in motion. The configuration is adapted to the available space, coding position, line speed and communication requirements.
CO₂ laser technology is commonly used for PET bottles and rigid packaging. The appropriate wavelength, power and optics are selected according to the packaging design, required code and production speed.
SPA2 C CO₂ laser coding systems include wavelength options designed for PET applications. For selected PET packaging projects, the SPARK CO₂ laser coder can also provide direct coding of dates, batch numbers and 2D codes.
UV and Green technologies can be considered when the application requires fine detail, specific contrast or reduced thermal impact on the substrate.
SPA2 D Green UV provides DPSS, Green and UV wavelength options for selected plastics and delicate packaging applications. The most suitable technology is defined after testing the actual PET pack.
PET packaging is not uniform. Bottle thickness, recycled content, colour, additives, surface finish and shape can affect the marking result.
This is particularly important for lightweight bottles and rPET packaging, where a configuration that works on one container may not deliver the same contrast or finish on another. Testing the real bottle allows us to assess code quality, readability and the most appropriate marking parameters before implementation.
Laser coding can mark dates, batch numbers and 2D codes on water, soft drinks, juices and other beverage bottles. Discover our beverage coding and marking solutions.
PET trays, tubs and containers can require variable product information for production and distribution. Explore our food coding and marking solutions.
PET bottles and containers used for cosmetics, hygiene and home-care products can be coded with batch information, references and traceability data.
Send us a PET bottle, container or sample pack and tell us what you need to mark. We will assess the substrate, code quality, contrast and cycle time to recommend the most suitable configuration.
