Course abstract

Students get acquainted with the general characteristics of food and beverage packaging materials and its functions, legal requirements and the latest trends in packaging development. Packing materials (paper, metal, glass, polymers and composite materials), their forms. Labels and their bonding equipment. Packing equipment. Packing in air and in modified environment - vacuum (VP); modified atmosphere (MAP) and equilibrium modified atmosphere (EMAP). Active and biodegradable packaging. Transport packaging. Processing and management of used packaging.

Requirements for awarding credit points

The exam is graded with a mark, where the grade is formed:
1. Independent work report, on the basis of which the student obtains a positive evaluation (accounting for 60% of the grade).
2. All three tests are successfully written (at least 4 points), All laboratory works, practical works and seminars are completed, all laboratory reports and homework assignments have a positive evaluation (accounting for 40% of the grade).
In order to be able to defend the report, all tests, laboratory works, practical works, seminars, homework must be included.

Description of the organization and tasks of students’ independent work

1st homework. Students conduct a questionnaire of 30 respondents in order to find out their knowledge and opinion on food packaging (submision of questionnaire results in electronic format).

2nd homework. Report - Package recycling, volume reduction / optimization options (at least 4 pages, submitted electronically).

Criteria for Evaluating Learning Outcomes

A colloquium consists of multiple choice and open-ended questions, it evaluates in the 10 point scale. In an each question has showed a maximal available points. The colloquium is successfully written if students get minimally 4 points. If the evaluation is lower than previously set, students should write the colloquium repeatedly (in this case the average evaluation of colloquium is summarized from both colloquiums (unsuccessfully and successfully written)). A laboratory works, practical works and seminars are evaluated as a pass.
