Packaging Engineer Job Description

A packaging engineer decides what a manufactured product ships in, and then proves that the decision holds up. In a manufacturing plant that means the bottle, carton, pouch or blister that touches the product, the case that groups units together, and the pallet load that rides a truck to a distribution center. BLS does not count packaging engineers separately: its 2018 SOC direct match title file places the title under Industrial Engineers, an occupation BLS describes as people who "devise efficient systems that integrate workers, machines, materials, information, and energy to make a product or provide a service."

The work starts with a brief from product development or operations. The engineer learns what is being protected (a glass vial, a frozen entree, a circuit board, a bag of lawn fertilizer), how fragile it is, how it will travel, what the line can run, and what the cost target is. From there the job moves through concept sketches, structural drawings, sample builds on a plotter table or a prototype thermoformer, and lab testing before anything is released to production.

Testing is the part of the job outsiders tend to miss. The International Safe Transit Association publishes families of test procedures: its general simulation series (3A, 3B, 3E and others) is described as simulating "the damage-producing motions, forces, conditions" of distribution, and its member performance tests, including 6-Amazon.com and 6-SAMSCLUB, were created by an ISTA member or in cooperation with ISTA to set unique requirements. ASTM International's D4169 is the standard practice for performance testing of shipping containers and systems. A packaging engineer picks the right protocol, writes the test plan, conditions samples, runs or witnesses the drops, vibration tables and compression tests, and reads the damage.

Once a design passes, the paperwork begins. The engineer writes a packaging specification (dimensions, board grade or film structure, print and label callouts, palletization pattern), loads it into the bill of materials, and issues an engineering change so purchasing can buy against it. New materials go through supplier qualification and line trials, where the engineer stands at a case erector, cartoner or form-fill-seal machine and watches whether the new carton feeds without jams and the seals hold.

The setting shapes the week. In food plants the engineer worries about shelf life, barrier films and how a package behaves through retort or freezing. In pharmaceutical and medical device plants every change runs through validation protocols and documented change control. In consumer goods the job leans toward cost reduction, retail display and e-commerce shipping, where each parcel is handled on its own through sortation and delivery.

Packaging engineers sit between departments that want different things: marketing wants shelf impact, procurement wants a cheaper board grade, operations wants faster changeovers, and quality wants zero damage claims. A large part of the job is making that trade-off visible with test data and cost math, then defending the result.

Degree paths. As a rough guide, packaging engineers hold a bachelor's degree, and BLS lists a bachelor's degree as the typical entry-level education for industrial engineers, the occupation that includes the title. Common majors are packaging science or packaging engineering, mechanical engineering, materials science, industrial engineering and chemical engineering. A packaging degree is built around container materials and testing; engineers from other majors usually pick that knowledge up on the job or through short courses.

Certification. The packaging-specific credential is the Certified Packaging Professional (CPP), which the Institute of Packaging Professionals (IoPP) has awarded since 1972. The eligibility rules are concrete. A candidate needs six years of experience in packaging or a closely related technical discipline, and a bachelor's degree in a packaging-related area counts toward that, so a packaging graduate qualifies after two years of work. Only current IoPP members may apply. For people with fewer than six years, IoPP offers the Certified Professionals in Training (CPIT) track: candidates start with the multiple-choice test and finish the second requirement after their sixth year in packaging. Holders keep the CPP by staying members and recertifying three times before it becomes a lifetime designation.

Licensure. Some packaging engineers also pursue a Professional Engineer (PE) license. BLS notes that experienced industrial engineers may obtain one, which lets them oversee other engineers and sign off on projects, and that licensure typically requires an engineering degree, a passing score on the Fundamentals of Engineering (FE) exam, relevant work experience and the PE exam.

Tools and knowledge to build:

• Structural design software such as ArtiosCAD for cartons and corrugated, and 3D CAD such as SolidWorks or Creo for bottles, closures and trays
• Pallet and load planning software for cube and truck utilization
• Test lab practice: drop testers, vibration tables, compression testers, environmental chambers, and the ISTA and ASTM procedures they serve
• Material grades: corrugated flute and edge crush values, paperboard calipers, PET, HDPE, PP and multilayer barrier films
• Specification control in an ERP or PLM system, plus engineering change discipline
• For regulated plants, validation protocols (installation, operational and performance qualification) and documented change control

Experience ladder. As a rough guide, the first two to three years are spent on testing, sample builds and spec writing under a senior engineer. Engineers with four to eight years typically own projects end to end, from brief to production launch. Senior and principal engineers set packaging platforms, approve new materials across product lines, and manage relationships with converters and co-packers.

Useful habits. Keep a test log that someone else could repeat, learn to read a converter's quote line by line, and spend time on the plant floor during line trials. The engineers who earn trust are the ones who can explain to a plant manager why a box failed, in terms the plant manager can act on.

BLS projects employment of industrial engineers, the occupation that contains packaging engineers, to grow 12 percent from 2025 to 2035, which it rates as much faster than the average for all occupations. It also projects about 23,100 openings for industrial engineers each year, on average, over the decade. BLS does not publish a separate projection for packaging engineers, so those figures describe the wider occupation rather than this title.

The occupation is spread across manufacturing and engineering services. BLS reports that industrial engineers held about 365,100 jobs in 2025, and that transportation equipment manufacturing employed 15% of them and professional, scientific, and technical services 14%. BLS does not break packaging engineers out of those counts.

BLS also publishes industry rows for the occupation. In May 2025, BLS put the median wage for industrial engineers at $102,830 in food manufacturing and $104,110 in pharmaceutical and medicine manufacturing. BLS does not report packaging engineers separately within either industry.

One state's rules are now a design input. California's packaging law, SB 54 (the Plastic Pollution Prevention and Packaging Producer Responsibility Act), moved from statute to enforceable rules in 2026: on May 1, 2026, the state Office of Administrative Law approved CalRecycle's permanent regulations, which took effect upon filing, and CalRecycle opened a portal called PEPRS for producer registration, reporting and compliance monitoring. CalRecycle's Nov. 2, 2026 baseline report restates the source reduction targets the producer responsibility organization must meet for plastic covered material, measured against a 2023 baseline: at least 10% by Jan. 1, 2027, 20% by Jan. 1, 2030 and 25% by Jan. 1, 2032. Progress is measured both by weight and by the number of plastic components, so the plastic in a package and the count of plastic parts are both on the table. For a packaging engineer at a company selling into California, that can mean redesign projects: fewer components, simpler material structures, and documented recyclability for each format. Sukhdev Singh Saini, global toothbrush and devices packaging lead at Colgate-Palmolive, told Packaging Dive in September 2025 that, with more states adopting extended producer responsibility programs, he anticipated "a lot of work being done on recyclability."

AI is reaching the lab, not replacing it. Packaging Dive reported in September 2025 that Colgate-Palmolive was exploring how simulations could validate new designs for components such as bottles, caps and spray pumps. Saini told the publication that without AI "we have to physically make a lot of samples to test," and he described the technology as a work in progress and not a 100% replacement yet. The same article quotes Tom Egan, vice president of industry services for the Association for Packaging and Processing Technologies, on using simulation models and digital twins to generate mockups rather than physically making and testing each version. In that reporting, simulation cuts down on physical samples rather than eliminating them: a consultant quoted in the piece said it can lower the cost of physical prototyping significantly, while the Colgate-Palmolive lead stopped short of calling it a full replacement.

Where the openings come from. Product launches, cost-down programs, plant moves, new filling lines, retailer test requirements and state packaging laws all generate packaging projects. Employers range from brand owners and their plants to converters, test labs and contract packagers, and the skills carry between them: running a test lab, writing a clean specification, and arguing a material change in dollars and compliance terms.

Dear Hiring Manager,

I am applying for the Packaging Engineer opening on your packaging development team. For the past four years I have worked as a packaging engineer at a mid-sized frozen foods manufacturer, where I own secondary and shipper packaging for two production lines and support primary film changes with our quality group.

My largest project last year replaced a two-piece shipper, a corrugated tray plus a separate sleeve, with a single wraparound case. I built samples on our plotter table, ran the transit tests our largest retail customer requires, and failed the first design on compression after a humidity conditioning cycle. I moved to a heavier liner, passed on the second round, and then spent three weeks on the floor tuning the case packer so changeover time did not grow. The new case removed one component from every shipment and cut our corrugated spend on that line.

I also manage our packaging specifications in the ERP system. When I arrived, a third of our specs were missing board grades or pallet patterns, which made supplier substitutions risky. I rebuilt them, added a change request form that procurement now uses before any material switch, and trained two technicians to run our drop and vibration equipment.

Your company's work on reducing plastic components in multipack formats is the kind of problem I want to take on next. I would bring a test-first habit, patience on the plant floor, and the ability to explain a packaging trade-off to marketing and finance without losing the engineering detail.

Thank you for your time. I would welcome a conversation about the role.

Sincerely, Jordan Ellison
