• Propylene polymer (Polypropylene: PP) is a plastic vapor permeation has slightly stronger than polymer ethylene nathon on the substance use and fat high heat radiating plus la destination hot-resistant food packaging plastic bags. Plastic straws, etc.
• poly propylene (Polypropylene: PP) plastic vapor permeability was negligible. Stronger than poly ethylene and fruit raised on high heat for making plastic bags, plastic food containers heat. Plastic straws, etc.
- Polypropylene (Polypropylene: PP) is a plastic vapor permeability slightly. More solid fatty substance and high heat resistant polymer used to make plastic sheet plastic food packing ที่ทน hot plastic syringe.
