Expiry dates, batch codes, and promotional identifiers must be printed accurately without compromising packaging integrity or food safety.<\/p>\n<p data-start=\"441\" data-end=\"554\">In recent years, laser coding has established itself as an advanced alternative to traditional ink-based systems.<\/p>\n<p data-start=\"556\" data-end=\"737\">With laser coding, we take a step forward in this field, offering a system capable of producing permanent, precise, and high-speed markings without direct contact with the material.<\/p>\n<hr data-start=\"739\" data-end=\"742\" \/>\n<h2 data-start=\"744\" data-end=\"792\"><strong data-start=\"744\" data-end=\"792\">A Permanent, Consumable-Free Coding Solution<\/strong><\/h2>\n<p data-start=\"794\" data-end=\"977\">Alphanumeric coding consists of marking combinations of letters, numbers, and symbols onto a product\u2019s packaging to identify it and enable tracking throughout the entire supply chain.<\/p>\n<p data-start=\"979\" data-end=\"1271\">When this process is carried out using laser technology, the marking is applied quickly, precisely, and permanently\u2014eliminating the need for inks or consumables and ensuring that the information does not deteriorate over time, through handling, or due to exposure to moisture and temperature.<\/p>\n<p data-start=\"1273\" data-end=\"1351\">This system allows key information to be incorporated into packaging, such as:<\/p>\n<ul data-start=\"1353\" data-end=\"1466\">\n<li data-section-id=\"cmjw4p\" data-start=\"1353\" data-end=\"1384\">\n<p data-start=\"1355\" data-end=\"1384\">Expiry or best-before dates<\/p>\n<\/li>\n<li data-section-id=\"1epp747\" data-start=\"1385\" data-end=\"1418\">\n<p data-start=\"1387\" data-end=\"1418\">Batch codes or serial numbers<\/p>\n<\/li>\n<li data-section-id=\"anlifl\" data-start=\"1419\" data-end=\"1466\">\n<p data-start=\"1421\" data-end=\"1466\">Custom text or product-specific information<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"1468\" data-end=\"1620\">In this way, at Pigmea we can integrate coding directly into the packaging without modifying its original design or affecting the material\u2019s properties.<\/p>\n<hr data-start=\"1622\" data-end=\"1625\" \/>\n<h2 data-start=\"1627\" data-end=\"1669\"><strong data-start=\"1627\" data-end=\"1669\">Greater Efficiency in Production Lines<\/strong><\/h2>\n<p data-start=\"1671\" data-end=\"1844\">One of the most notable aspects of laser coding is its ability to integrate into high-speed production lines\u2014especially relevant in sectors with large manufacturing volumes.<\/p>\n<p data-start=\"1846\" data-end=\"2051\">In addition to ensuring legible and permanent codes, this technology allows for quick changes in marking content, enabling adaptation to different product references or campaigns without complex processes.<\/p>\n<p data-start=\"2053\" data-end=\"2257\">Another key advantage is that, by not using inks or ribbons, consumables are eliminated from the process. This reduces operating costs, minimizes waste generation, and contributes to improved food safety.<\/p>\n<hr data-start=\"2259\" data-end=\"2262\" \/>\n<h2 data-start=\"2264\" data-end=\"2308\"><strong data-start=\"2264\" data-end=\"2308\">Applications Across Different Industries<\/strong><\/h2>\n<p data-start=\"2310\" data-end=\"2448\">Laser alphanumeric coding is a versatile solution that can be applied to different types of flexible packaging across multiple industries.<\/p>\n<p data-start=\"2450\" data-end=\"2633\">In the food industry, for example, it enables coding on snack bags, chocolate wrappers, coffee packaging, or fresh products\u2014ensuring proper batch identification and consumption dates.<\/p>\n<p data-start=\"2635\" data-end=\"2894\">It is also particularly useful for beverages and liquid products, where packaging traceability is essential, as well as in sectors such as pharmaceuticals, cosmetics, and logistics, where control of serial numbers and batches is a key operational requirement.<\/p>\n<hr data-start=\"2896\" data-end=\"2899\" \/>\n<h2 data-start=\"2901\" data-end=\"2943\"><strong data-start=\"2901\" data-end=\"2943\">Innovation at the Service of Packaging<\/strong><\/h2>\n<p data-start=\"2945\" data-end=\"3106\">With the integration of laser coding, we reinforce our commitment to solutions that enhance traceability, efficiency, and sustainability in the packaging sector.<\/p>\n<p data-start=\"3108\" data-end=\"3318\">Beyond meeting regulatory requirements, this technology allows us to offer our clients packaging that integrates key information in a durable, precise, and secure way\u2014while preserving the material\u2019s properties.<\/p>\n<p data-start=\"3320\" data-end=\"3440\">At Pigmea, we continue working to develop solutions that respond to new industry needs and current packaging challenges.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Alphanumeric codes on flexible packaging are an essential part of traceability and production control in the food and FMCG industries.
