A packaging engineer creates and designs boxes, cartons, bottles, plastic wraps, and other consumer goods packaging. Professionals study various types of materials and work to improve industrial packaging techniques. They determine which materials to use to protect specific goods using expert knowledge of physics, chemistry, mechanical engineering, and marketing. Packaging engineers work in a variety of settings, including R&D labs, manufacturing plants, and private consulting firms.
A research and development packaging engineer typically conducts experiments on various types of materials in a specialized laboratory setting. A professional, for example, might want to develop a new type of plastic food container that is durable, recyclable, and microwave-safe. He or she investigates the properties of various plastic polymers to see which ones best match the desired characteristics. The packaging engineer then collaborates with a group of scientists to create prototypes and put them through a series of tests to see how effective they are.
Many packaging engineers are concerned with the creation of appealing, effective containers as well as cost-effective manufacturing methods. They begin by deciding which materials, such as cardboard, glass, plastic, or wood, will be used to package a given product. Engineers frequently try to reduce waste by using as little packaging material as possible. To help them create the most efficient designs, they use mathematical models and computer-aided drafting software. Professionals also assist in the design and construction of industrial equipment used in the manufacturing and packaging of consumer goods.
The educational requirements for becoming a packaging engineer differ depending on where you live. Master’s degrees in packaging science, materials science, or mechanical engineering are common among those who work in manufacturing plants and consulting firms. Doctoral degrees are typically held by those involved in the research and development of new materials, methods, and processing equipment. In some countries, packaging engineers must pass licensing exams to demonstrate their knowledge of the job’s fundamentals as well as legal issues such as patents and consumer safety.
New packaging engineers typically work as assistants to more experienced engineers for several months before taking on projects on their own. Under the supervision of senior engineers, assistants are often in charge of writing grant proposals, contacting clients, and conducting research. An individual can earn additional responsibilities and have the opportunity to advance within his or her company with time and experience. After gaining several years of experience in the field, many skilled packaging engineers become involved in marketing their designs.
