Mechanical behaviour and durability of disposable food containers / Egenskaper och hållbarhet av engångsförpackningar för livsmedel

Johansson, Frida January 2024 (has links)
A large proportion of the food that is consumed daily is bought ready-madeand is served on some sort of disposable container. ConServ AB developsand produces sustainable food packaging made from Areca palm leaves.The company wonders how durable the product is so that they can further investigate on their own what form the product should have for thebest durability. They also wonder how durable the product is during usage.The aim is to conduct a pilot study to investigate and identify trends regarding the material’s durability and mechanical behaviour during and as aresult of simulated useage. The goal is to use tensile tests and photograhicmethods to produce a basis with data on the material’s behaviour for ConServ.In order to be able to evaluate the durability and behavior of the product,a systematic study has been carried out where tensile tests were performedon test pieces exposed to a food simulant in the form of water or vinegarsolution. The test pieces were exposed for 0, 1, 6, 24 or 48 hours and testswere performed immediately after exposure.Experimental data show that the durability of the product depends to alarge extent on the fiber direction, where the test pieces taken perpendicularto the fiber direction performed worse in the tensile test. The mechanicalbehavior of the material is affected by the time it is exposed to liquid andbecomes more ductile with time.
