Increased demand for laser coding from fruit and vegetable producers
Macsa ID meets the diverse requirements of the fresh produce sector by offering a range of laser coding technologies specially designed to handle different substrates and materials. Whilst inkjet coding systems have typically been used by producers, processors and packers, laser coding is becoming increasingly popular due to its versatility, permanence, cleanliness and durability, as well as environmental benefits.
Macsa ID's laser coders have been developed to ensure the traceability of fruit and vegetables from ‘farm to fork’, to properly track and verify every step of the distribution of produce and identify their origin if necessary.
Laser coding technology offers versatility, permanence, cleanliness and durability, as well as environmental benefits
The company’s systems are suitable for a wide range of applications including marking on fruit and vegetable trays and processes such as cutting or micro-perforation of plastic film to allow the circulation of air inside fruit containers.
Macsa ID’s powerful HPD CO2 lasers offer high performance and optimum definition and are mainly used in packaging, pre-cutting and packaging micro-perforation, as well as high definition coding.
Pre-cutting laser systems are used to pre-cut and cut films in flexible packaging production. Micro perforation laser systems perforate plastic film for fresh foods and make the packaging porous allowing products to continue maturing and ultimately extend shelf life.
Laser marking is also opening up new opportunities for the fresh produce industry such as coding directly on to a product’s skin. The origin of the ‘natural mark’ concept (direct marking on the product) has arisen due to the interest in returning to the sale of products in bulk or by units.
It also leads to savings in primary packaging and represents a sustainable coding system by not using consumables or materials. In addition, this technique enhances brand impact and ‘on-shelf’ appeal.
In order to meet these requirements, the most suitable coding system is undoubtedly the laser. Coding on to fruit and vegetable skin needs a system that guarantees the permanence of the code yet also reinforces the quality of the products.
With the Macsa ID SPA CB 30 HPD laser system, a high definition and legible mark is obtained, even if the products skin is not smooth. For example, the whitish marking on the green of a cucumber is achieved by applying 100% power and at a cadence rate appropriate to the marking lines of this type of product.
Traditional adhesive labels, which often fall off due to friction or movement, are not needed with laser marking which helps reduce plastic, energy and CO2 emissions. In addition, lasers also allow larger printing surfaces with more space for information.
Laser technology is widely recognised to generate just 1% of the carbon emissions needed to produce a label of a similar size, with less paper, ink and glue, as well as the energy used in cutting labels and associated transport or warehousing costs.
