1 Scope

This document specifies the requirements for blow-molded polypropylene round-bottom containers with a capacity of not more than 2L (including 2L) for liquid food packaging. Book

The document also specifies quality tolerances, dimensional tolerances, sampling methods, test requirements and performance requirements for blow-molded polypropylene containers for liquid food packaging.

NOTE. It is not intended that polypropylene is the only polymer suitable for this application, as include high density polyethylene (PE-HD), polyethylene terephthalate (PET)

Other polymers, etc., are also suitable.

3 Terms and Definitions

The following terms and definitions apply to this document.

NOTE. For terms and definitions in this document, please refer to ISO 472.Containers produced using ISBM technology have a neck height (H) from the highest point of the container neck to

The vertical distance of the bottom surface of the support ledge. The full capacity can also be determined by the method specified in Appendix B by using a specific volume test equipment. For bottles and loose

For mouth containers, the nominal capacity is about 90% of the full capacity.
