Functional masterbatch storage: keep every opened bag traceable
Storage starts with dry, intact packaging, but traceability continues after a bag is opened. The lot, opening date, remaining quantity and line where the material was used need to stay connected.
Production note
Storage starts with dry, intact packaging, but traceability continues after a bag is opened. The lot, opening date, remaining quantity and line where the material was used need to stay connected.
We recommend returning opened material to sealed, labelled packaging and avoiding unmarked transfer containers. Where drying is specified for a particular grade, the actual temperature, time and equipment should be recorded rather than relying on a general plant habit.
Keep the label with the retained sample
For each delivery, retain the product label, lot reference and a representative sealed sample according to the agreed quality procedure. If a later comparison is needed, these records allow our production and technical teams to examine the material that was actually used.
