Your have many choices when buying a PET container or its alternatives for your home. Yet, all the labels and acronyms can be highly confusing. Typically found at the bottom of takeaway packages and cups, they leave many consumers dumbfounded as to their meaning. If you fall under the category, do not worry, we have created this article to cover the two most common types of plastic containers – PET (Polyethylene terethalate ) and PP (Polypropylene). Although both types of plastic are recyclable and pre-owned commonly in the food industry, there are some essential differences that you might want to consider.
Learning about PET material
PET is globally identified as a safe, recyclable packaging material for food and non-food products. PET packaging is selected for a variety of applications due to the fact that it is risk-free, solid, unbreakable and chemically 100% recyclable into the same PET products (fibre and containers).
Manufacturers utilize PET to package products as a result of its stamina, thermo-stability, and transparency. It is likewise light which decreases both the costs and carbon emissions associated with transport. Retailers utilize PET since it promotes high item presence: its light-weight facilitates shelf stacking, and its unbreakable high quality ensures security, item integrity and a reduction in breakages.
Consumers pick PET due to the fact that it is portable, light-weight, re-sealable for effective on-the-go hydration, 100% secure and 100% recyclable.
What is the Distinction in between PET and PP Containers?
The first big difference between PET and PP containers lies in their heat or cold resistance. In particular, you need to be familiar with “fill temperature’ which refers to the temperature of food or beverage in which your container can safely hold. In this case, PP containers perform slightly better than PET containers as they can hold both higher ad lower temperatures. Yet, fill temperature is not the sole factor here, as you shoudl also consider “resistance temperature”. Resistence temperature refers to how well your plastic containers hold up around the surrounding temperature. This time round, PET containers outperform PP containers. Being durable in both cold and hot environments.
Durability and physical resistance
PET plastic cups are a little more valuable than PP containers when it pertains to damage resistance. Their durability allows them to be used in a greater number of environments without fear of them breaking and thus endangering our health.
Inert and protection
One other advantage that PET containers offers over PP containers is their impermeability. PET containers protect their contents from surrounding oxygen, thus preventing oxidising processes that would spoil the taste of the food or beverage. That said, PP containers do compensate by providing better protection from moisture. Both plastics offer fair reisstance to acids and oils.
