PET vs Polypropylene (PP)
Appearance PET Polypropylene (PP)
Chemical composition Copolymer of ethylene glycol and terephthalic acid monomers Polymerized propylene monomers
Transparency Highly transparent, suitable for transparent packaging Moderately transparent when copolymerized with ethylene
Mechanical properties High tensile strength and toughness Moderate strength and flexibility
Applications Transparent bottles, food packaging Flexible applications, textiles, automotive parts
Recyclability Highly recyclable Hfirst datasetighly recyclable, several elements of the packaging can be recycled together.
Impact on the environment Decrease in energy demand in production Concerns about chlorine release during production and recycling
Adequacy Premium packaging and applications requiring clarity Versatile, cost-effective and flexible applications
PET vs. Polyvinyl Chloride (PVC)
Transparency Highly transparent, suitable for transparent packaging Transparent or opaque, used in various applications
Flexibility Semi-rigid, resistant Flexible when plasticized, rigid when not plasticized
Applications Food and beverage containers, transparent packaging Pipes, toys, auto parts, cable insulation
The challenges of recycling Easier recycling process than PVC Challenges related to additives and chlorine content
Sustainability Good chemical resistance, resistant to microbial attack Durable, chemical resistant, but degrades in sunlight
PET and high-density polyethylene (HDPE)
Appearance PET High-density polyethylene (HDPE)
Appearance Clear plastic Opaque plastic
Stress cracking Resistant to stress cracking High propensity for stress cracking, especially under environmental conditions
Temperature resistance Lower operating temperature (145°F) Higher operating temperature (160°F)
Clarity Excellent clarity, natural barrier properties Less clarity, better durability in harsh conditions
Recyclability Perfectly suited for recycling Highly recyclable, with many applications
Sustainability Low diffusion coefficient, sustainable choice Durable, reduces packaging waste
PET vs Polycarbonate (PC)
Appearance PET Polycarbonate (PC)
Shock resistance Good mechanical resistance Better impact resistance, but poor stress cracking resistance
Chemical resistance Resistant to household cleaners and acids Limited chemical resistance, not ideal for harsh environments
UV resistance Susceptible to degradation under UV effects UV resistant
Applications Food grade packaging, transparent containers Impact resistant applications where UV protection is not required
Environmental considerations Reducing environmental impact during production Concerns over chemical composition and recycling issues
