PP (Polypropylene) is one of the most commonly used plastics in the packaging industry. It is colorless, odorless, non-toxic, and currently the lightest among general-purpose plastics. Widely used in food, pharmaceutical, and healthcare packaging.
Key Advantages of PP:
- Heat Resistant: Can withstand boiling water and high-temperature steam sterilization. One of the few plastics suitable for hot water disinfection.
- Chemical Stability: Resistant to acids, alkalis, and other chemicals-ideal for product storage.
- High Safety: Low monomer content and minimal use of additives during processing; safe for food contact.
- Good Mechanical Strength: High tensile strength and stable structure.
Common Applications:
At our company, PP is mainly used for caps (e.g., screw caps, safety caps), bottles, and portable packaging boxes, offering a balance between practicality and cost.
If you're looking for a heat-resistant, easy-to-disinfect, and safe packaging material, PP is an excellent option.
