After de-flashing all bottles are checked for minimum top load,
presence of holes and for tight performance.
Default bottles are discarded immediately.

Internal pressure test:
bottle filled 1/3 of volume with Igepal 10% solution
bottle closed with cap and pressurized (e.g. 400 mbar)
equipment placed in hot room (40°C)
timer detects time of failure (pressure loss)
P = 400 mbar

For performance evaluation of containers which is not possible to beevaluated according to standards, is used the “panel test” (Procedureis described in a standard).A number of “experts” is requested to evaluate separately the performance of an item (e.g. smell) and to report separately about their findings.

Status in Europe today is a mixture of:• EU-Directives and National Regulations
EU-Directives:• Framework Directive (1989)
• Specific Directives (e.g. for Plastics)• EU-Directive 2002/72/EC

• Resin supplier migration tests
• It is the responsibility of resin converters and food packers to make
sure that finished articles meet the relevant migration limits
• Resin suppliers have no control over customers’ process conditions
– They cannot state migration compliance

• Voluntary certification, which has the purpose to guarantee a consistent
high level of quality within the time
• The certification covers (or can cover): Manufacturing plants, Labs,
Offices and related working procedures and demands to keep records
and an up-date databank
• Certification is issued on the basis of internal and external audits, after
evaluation of activity records and QC data consistency.
