Within its hollow glass sealing applications, Ribipack has created a quality concept for hollow glass called the Internal Functional Quality (IFQ). IFQ guarantees that the hollow glass container used on the filling line is in the condition required by the filling company, regardless of production time or length & type of logistical cycle - including warehousing. The following quality characteristics can be individually or simultaneously ensured: Absence of dust & particles of any type; absence of foreign bodies; absence of bacteria & spore; absence of moisture & water traces; absence of any hollow glass container internal surface quality problem, usually due to storage in humid environments with significant temperature gradients; tracking container by container.
