Engineering Co-Op II

Job Description

This position is responsible for planning, leading, and performing a wide variety of analyses and evaluations on materials utilized in paperboard, packaging substrates, and finished carton structures in support of Global R&D (GRD) for new product development for Fresh Produce Packaging. This role involves regular exposure to a variety of fresh fruits and vegetables and is based fully onsite, Monday through Friday, at our Louisville, CO location.

• Perform chemical, physical, structural, and performance testing of various substrates (paper, board, film, laminations, etc.), carton structures, and prototype/finished products in accordance with industry-standard procedures from sources such as ASTM, TAPPI, ISTA, and any other internal (GPI-based) or external (customer) specifications and requirements.
• Analytical methods and techniques employed may include:
  • FTIR:
    Fourier transform infrared spectroscopy.
  • DSC:
    Differential scanning calorimetry.
  • SEM:
    Scanning electron microscopy (with EDS, electron dispersive spectroscopy).
  • Instron Universal Test Apparatus Analysis for the determination of tensile, and compressive-type properties of materials.
  • Optical microscopy and sample imaging.
  • Physical test evaluations on paperboard/structures, including COF, stiffness, score bend, and tear.
  • Temperature/humidity testing of substrates, structures, and cartons/products for environmental integrity at various conditions.
  • Visual observation and comparison.
• Develop new test methods and procedures when required, in support of the analysis of produce packaging materials, incorporating and utilizing the expertise acquired from education, work experience, and knowledge obtained working in the GRD Group.
• Writes and issues detailed data/science-based reports, emails, and presentations stating results, conclusions, and future course of action from the lab work completed and data obtained. Communicates the project’s critical information obtained with customers, and various levels of management, in a concise, and scientific manner that is data-driven, and scientifically sound.
• Appropriately uses all Lab/test equipment within the GRD-Louisville facility.

• 5-7 semesters (or equivalent) of progress toward BA/BS in a Science/Engineering-based technical degree, such as Chemistry, Mechanical Engineering, Materials Science, Physics, Packaging Science, etc. BA/BS degree preferred.
• Experience in a ‘working’ physical/chemical lab environment achieved through school/university, and/or work experience/job functions.
• Packaging, chemical, physical, and /materials science test experience acquired through work/co-op/internship within the packaging, materials, or fresh produce industries is a strong asset to this position.
• Additionally, familiarization with any of the various analytical methods noted, or other test instrumentation, and advanced materials analysis experience, and knowledge is also a definite benefit.
• Additional skills and coursework, knowledge and/or experience in beverage/food packaging, structural design, and paperboard science is also beneficial.

• Frequent bending, stooping, squatting, and frequent movement throughout the facility for extended periods of time up to 8 hours.
• Occasional lifting up to 20 lbs.
• Reading computer screen or other electronic devices.
• Use of various office, hand tools or electrical equipment.
• Employee is required to wear steel toe shoes, safety glasses and hearing protection when in the manufacturing area.
• Occasionally exposed to airborne particles and times of increased heat and humidity.
• Noise level in the immediate work environment is normally quiet, but requires exposure to a noisy manufacturing environment.
