Learning objectives
Knowledge and understanding
At the end of the course, the student will have acquired the basic knowledge relating to packaging technologies and the facilities necessary to apply industrially.
Applying knowledge and understanding
The student will be able to design a packaging for food starting from the materials considered suitable for contact and defining the technologies and facilities required for the complete process of packaging. The student will be able to use the acquired knowledge to analyze and process numerical data to support their decision-making.
Making judgments
The student will be able to assess the impact of design decisions on the packaging of a primary, secondary or tertiary evaluate and know what actions to take in order to innovate the product as currently exists.
Communication skills
The student will acquire the vocabulary specific to the issues inherent in the packaging sector. It is expected that at the end of the course, the student is able to communicate, orally and in writing, including by resolution of numerical problems, the main contents of the course
Learning skills
Students who have attended the course will be able to deepen their knowledge in the field of suitability for contact with food, food packaging technologies, processes, secondary packaging and recycling processes through consultation autonomous specialized texts, journals or outreach, even outside of the topics covered closely in class.
