What Are Coding and Marking Systems?
In the packaging industry, coding and marking systems are essential tools that ensure products move smoothly through supply chains, meet regulatory standards, and provide vital information to consumers. Whether they are handling bottled beverages, pharmaceutical cartons, or e-commerce parcels, these systems are the silent workhorses behind the scenes.
Coding and marking systems provide essential information that is placed on exterior packaging – expiration dates, lot or batch numbers, barcodes and QR codes, serial numbers, product identifiers, and regulatory compliance marks. These codes and identifiers must be fast, legible, accurate, and durable.
Product packaging and the need for effective coding and marking
As we move into the future, packaging standards are only becoming more strict and require a solution that can not only provide high quality printing on a variety of products, but also pass rigorous testing and scanning protocols. In March 2026, IndexBox outlined the many changing trends in the packaging industry. By 2035, the food and beverage industry will see a shift towards stricter food safety regulations with a need for better readability on product labeling, as well as including more granular and accurate information that can be scanned for compliance much easier and faster than ever before.

In the pharmaceutical industry, where standards are even more stringent, marking and coding systems will have to be flawlessly compliant, and will shift from not just marking on packaging, but direct marking on medical devices and containers themselves. (1)
Custom Coding and Marking Solutions For Every Industry
Coding and marking systems have a multitude of applications in a variety of industries – including food and beverage, pharmaceutical, cannabis, and e-commerce. Each industry requires an automation solution that is tailored to their specific needs and industry standards:

Pharmaceutical
- Serialization, lot numbers, expiration dates
- Strict regulations make accuracy critical
Consumer Goods
- Branding, promotional codes, manufacturing info
- Applied to labels, boxes, bottles, and tubes
E-commerce & Logistics
- Shipping barcodes, tracking numbers, return labels
- Print-and-apply systems used on corrugated packaging and mailers
Types of Coding and Marking Technologies
Inkjet Coding
Pineberry leverages a host of technologies to assist with coding and marking on various products. Inkjet systems – especially continuous inkjet (CIJ) and thermal inkjet (TIJ) – are widely used for their flexibility and speed. Inkjet systems are best used for cartons, films, plastics, metals and small character printing on product packaging. The key advantages of inkjet systems are that they are effective on almost any type of material substrate, they dry faster than other types of inks and are generally lower maintenance than other types of printing systems.
Laser Marking
As opposed to using inks, laser marking systems use a focused beam to etch on the surface of the material. Laser marking is best for more rigid substrates like glass and metal and is advantageous when a business needs to print permanent, tamper-proof codes onto packaging. It uses no inks or ribbons, and the marks printed are extremely durable and highly precise. There is typically a higher upfront cost for these systems.
Thermal Transfer & Print‑and‑Apply Systems
In addition to inket and laser printing systems, thermal transfer overprinters (TTO) and print‑and‑apply labelers are more common for flexible packaging. They are especially effective for printing on labels, pouches, bags, and more pliable packaging types.
How to Choose the Right System
Choosing the correct coding and marking system for your business means evaluating materials, speed, and compliance requirements. Material, or substrate, compatibility is of utmost importance to ensure the system matches the material. Different materials, such as paperboard, plastic, metal, glass, and film respond differently to ink, heat, or laser energy. Matching the system to the type of material is key to ensuring quality printing on your product packaging.
Line speed is also a consideration – high-speed packaging lines may require a specific system to provide a consistent rate and speed, while maintaining the quality of the marking and coding on the packaging. High‑speed packaging lines may require CIJ or laser systems, while slower or intermittent lines can use TIJ, TTO, or print‑and‑apply.
And any printing on packaging must be strict standards and compliance requirements. Industries like food, pharmaceutical, and cosmetics often require: GS1‑compliant barcodes, serialized codes, permanent, and non‑removable marks. Laser or high‑resolution inkjet may be necessary in this instance to ensure full compliance with industry standards and benchmarks.
Common Mistakes
Many companies run into issues when selecting or integrating coding and marking systems. Avoiding these mistakes ensures smoother implementation and fewer production disruptions.
Common pitfalls could include:
- Choosing a system based solely on price instead of long‑term cost of ownership
- Ignoring substrate testing, leading to poor adhesion or readability
- Underestimating line speed requirements, causing smudging or misprints
- Improper placement on the packaging line, resulting in inconsistent print quality
Integration into Packaging Lines
Coding and marking systems must be strategically placed to ensure accuracy and efficiency in packaging line coding. Upstream vs. downstream placement is a major consideration – will the coding occur before sealing or labeling, or vice versa? How the product is handled is also important, as each label must be clean and readable after passing through the production line. And the system must be integrated with other equipment in the line – friction feeders, vision inspection, labeling, conveyors, and end-of-line automation. Proper integration reduces rework, improves traceability, and supports automated quality checks across the board.
How can Pineberry’s marking and coding systems help with ensuring your products are properly labeled and compliant with industry standards?
Pineberry’s Print and Apply Solution
Pineberry has designed robust systems to assist businesses with coding and marking on a variety of packaging types. We integrate inkjet coding and labeling technologies to full transports: feeders, vacuum conveyors, exit conveyors, or simple friction feeders for marking, labeling, coding, personalization, and other applications.
The Benefits of Pineberry’s Labeling and Coding Systems
Pineberry’s marking and coding systems ensure your products adhere to strict standards across industries. First and foremost is compliance – many industries are heavily regulated and scrutinized. As such, products must include legally required information like expiration dates, traceability codes, and safety markings. Traceability is also a huge factor – batch and lot codes help track products across the supply chain, which is vital for managing recalls, audits, and supply chain transparency. Our systems are also beneficial for operational efficiency – our automated systems reduce errors and downtime compared to manual labeling or stamping. This cuts down on labour costs and increases productivity across your production lines.
And it’s not just industry standards that are aligned when using our automation solutions – our solutions also help instill consumer confidence – legible, consistent codes help assure customers that a product is authentic and safe to consume or use. With high quality printing, marking, and coding, we also provide effective anti-counterfeiting measures that help to fight against fake goods and gray market activities through quality serialized and scannable codes that hold up against scrutiny.
