* Vacuum Packaging *

I have been researching on using the most appropriate material for the product- beef pastrami. The most suitable packaging material to use is LDPE ( Low density polyethylene) as it can withstand a minimum temperature of -50 deg celsius. This is important as after vacuum pack, we have to blast freeze at a temperature of -18 deg celsius.Furthermore, this material is tough and flexible. Compared to HDPE, its resilience is higher. Resilience refers to the ability of the material to recover the energy that it has lost when it was being deformed.
