What is PET?
PET also known as polyethylene terephthalate is a plastic resin and a form of polyester. This plas tic is commonly used to make fibers for clothing and containers for food and liquid. Additionally, it is used in thermoforming for manufacturing. A good sample of PET are bottles used by the soda companies – can be FDA approved and safe for storing food for consumers.
Additionally, PET is the most common thermoplastic polymer resin of the polyester family and is used in fibers for clothing, containers for liquids and foods, and in combination with glass fiber for engineering resins.
What is PP?
PP is a thermoplastic polymer used in a variety of applications. Its scientific name is polypropene. You can find this plastic being used to package things like yogurt, medicine, drinks, and condiments.
It is a white, mechanically rugged material and has a high chemical resistance. Polypropylene is the second-most widely produced commodity plastic (after polyethylene) and it is often used in packaging and labeling. Mostly not recycled
PET has got greater strength than polypropylene (PP) of the same dimension
PET will not break as polypropylene (PP) do when tightened too much
PET can be tensioned up to 50% more than polypropylene (PP) of equivalent size. It won't relax or elongate like polypropylene PET has lower camber tendency compared to polypropylene (PP)
PET is more temperature resistant than polypropylene (PP)
The plastic needed to pack the products you manufacture depends on what goods you are working with. If you have concerns on what material can go with your items, and if there are questions regarding PET and PP materials, you may reach our support team at firstname.lastname@example.org.
