What is packaging engineering?

Packaging engineering is a technical discipline that combines engineering, industrial design, materials science, and marketing to develop packaging solutions that meet multiple objectives: protecting the product, communicating its value, complying with regulations, optimizing costs, and reducing environmental impact. Packaging engineers not only design the packaging but also ensure efficiency throughout the entire production process, from raw materials to the point of sale.

The scope of packaging engineering goes beyond the container itself. It involves a systemic view of the entire product lifecycle, encompassing production, logistics, storage, and the end-user experience. This makes packaging engineering key in sectors as varied as food and beverage, pharmaceuticals, cosmetics, hygiene, and any other field that requires customized packaging solutions.

Evolution and current trends

Packaging engineering has undergone significant evolution in recent decades. Some of the major trends include:

  • Sustainability: Increasing use of recycled, biodegradable materials and processes that reduce the carbon footprint.
  • Automation and Industry 4.0: Integration of robots and advanced control systems into packaging lines to maximize efficiency, obtain real-time data, and reduce errors.
  • Smart Packaging: Incorporating sensors, RFID, or QR codes that allow product tracking, monitoring its status, and providing additional information to the consumer.
  • User-centered design: : Search for the best user experience, facilitating the opening, handling and disposal of the packaging.

These trends reflect the growing complexity of the industry and the need for professionals and companies specialized in packaging engineering.

Basic principles of packaging engineering

Packaging functionality

Every container fulfills at least three essential functions:

  1. Protect the product: Avoid physical, chemical or biological damage that may affect the quality or integrity of the product.
  2. Communicate: Serve as an information and marketing support, including labeling, instructions for use and branding.
  3. Facilitate logistics: Allow efficient handling and transportation, optimizing space and ensuring product stability.

The balance of these three functions is the basis of packaging engineering. The packaging should be robust enough to protect, attractive to sell, and practical to handle.

Selection of materials

Selecting the material is one of the most critical steps. There are multiple options:

  • Plastics (PET, PE, PP, PVC…): Lightness, resistance and high versatility.
  • Paper and cardboard: Sustainable and easy to print, ideal for branding.
  • Glass: Excellent barrier against gases and aromas, highly valued for premium products.
  • Metals(aluminum, tinplate…): High durability and protection against light and oxygen.

The selection depends on factors such as product type, storage and transportation conditions, required shelf life, and the desired environmental impact.

Structural and graphic design

Packaging design encompasses both structural aspects, such as shapes, closures, dimensions and robustness, and graphic aspects, such as colours, typography, images and messages. Good structural design ensures product integrity during handling and transportation, while an attractive graphic design communicates brand identity and influences consumer choice.

Ergonomics and usability

Ergonomics is an often overlooked but highly important aspect. Packaging should be easy to handle, open, and close. Otherwise, it negatively affects the user experience. Similarly, in production and warehouse environments, packaging design should make staff tasks easier, reduce occupational risks, and increase efficiency.

¿Why is packaging engineering crucial?

Product protection

One of the primary objectives of packaging is to ensure that the product reaches the consumer in perfect condition. Packaging engineers consider transportation conditions, such as vibrations, impacts, and temperature changes; shelf life; and end-consumer usage. Poor design can result in claims, damaged products, and financial losses.

Cost optimization

Packaging that is too expensive can reduce profit margins, while packaging that is too weak can lead to higher losses due to damaged products. Packaging engineering seeks the optimal balance between cost and protection, analyzing variables such as:

  • Material thickness
  • Closure type
  • Printing technologies
  • Production processes

Through redesign and optimization, it is possible to reduce material usage, cutting production times and minimizing waste, generating substantial savings.

Regulatory and legal compliance

The packaging industry is subject to a wide range of regulations, especially in sectors such as food, pharmaceuticals, and chemicals. Packaging engineers must ensure that packaging complies with standards related to the food safety, the protection of sensitive substances, the correct labeling and the waste control failure to comply with these regulations may result in financial penalties and product recall.

Sustainability and environment

Concern for the environment is on the rise, and consumers are increasingly paying attention to the ecological impact of their purchases. Packaging engineering seeks to develop more sustainable solutions by reducing the carbon footprint and enhancing recyclability and biodegradability. This not only benefits the planet but also improves a brand’s reputation and fosters loyalty among an increasingly conscious audience.

Packaging engineering as a service: a comprehensive approach

The packaging engineering as a service involves delegating all stages of packaging development to external professionals—or a specialized team within the company itself. It’s a comprehensive approach that ranges from the initial needs analysis to the implementation of optimized machinery and production line solutions.

Scope and phases of the service

A comprehensive packaging engineering service typically includes:

  1. Consulting and diagnosis
  2. Design and prototyping
  3. Testing and validation
  4. Implementation and monitoring

Each phase provides specific value and is supported by the technical knowledge and experience of specialists in the field. Below, we delve into each of these stages.

1.- Consulting and diagnosis

The process begins with an analysis of the company’s current situation, taking into account factors such as:

  • Product type and its protection requirements.
  • Existing production processes.
  • Current costs of materials and logistics.
  • Branding and marketing needs.
  • Regulatory and environmental challenges.

Based on this analysis, the packaging engineering team develops a comprehensive strategy for optimization. This includes recommendations for material selection, packaging redesign, and the potential integration of new machinery.

2.- Design and prototyping

Once the plan is defined, the creative and technical phase of the design begins. CAD tools and simulation software are used to develop virtual models, which are then translated into physical prototypes to validate design concepts. Feedback from all key parties (marketing, production, logistics, sales) is essential to ensure that the packaging meets both functional and strategic objectives.

4.- Testing and validation

Before launching the packaging into mass production, a series of performance tests are conducted, including:

  • Compression tests to verify load resistance.
  • Drop tests to simulate impacts during transport.
  • Sealing and leaking evaluations to ensure tightness and protection.
  • Stability and stacking tests to optimize storage and handling.

For food and pharmaceutical products, additional tests, such as substance migration and microbiological evaluations, are performed to certify packaging safety.

5.- Implementation and monitoring

The final phase consists of integrating the packaging solution into the production line, which may involve the purchase or modification of machinery, staff training, and the redefinition of logistics processes. Once implemented, monitoring is carried out to measure the effectiveness of the new design and correct any issues. Packaging engineering service does not end with the delivery of the project; rather, a collaboration is maintained for continuous improvement.
