PACKAGING POLYMER FAMILIES
Polypropylene (PP)
Polypropylene is a polymer family used in many packaging and product applications, including selected rigid packs and films. Its properties depend on grade, formulation and the finished construction.
POLYPROPYLENE IN PRACTICE
- Identify the gradeObtain the actual material specification.
- Test the packValidate protection and process conditions.
- Control the claimsVerify market and environmental requirements.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
A polymer name is a starting point for qualification.
A packaging team proposes replacing one PP pack with another. It reviews the actual grade and finished-pack performance rather than approving the change from the shared polymer abbreviation.
