Materjali Użati fit-Tazzi tal-Kafè tal-plastik

Materjali komuni għat-tazzi tal-kafè tal-plastik jinkludu polystyrene (PS), polypropylene (PP) u polyethylene (PE). Il-polistirene (PS) għandu trasparenza għolja (trażmissjoni tad-dawl akbar minn jew ugwali għal 90%), iżda reżistenza fqira tas-sħana (<60℃) and is brittle. Polypropylene (PP) has high mechanical strength (tensile strength 30-40MPa) and high temperature resistance (120℃), but lower transparency. Polyethylene (PE) is highly corrosion-resistant and inexpensive, but lacks rigidity (flexural modulus approximately 200-300MPa). PP material, because it meets food contact safety standards (FDA certification), is more suitable for holding hot drinks. It is recommended to choose based on the usage scenario: PS is suitable for displaying cold drinks, PP is suitable for taking hot coffee to go, and PE is suitable for low-cost short-term use.
