How should empty buckets and cups be stored before filling?

Empty buckets, cups and lids should be stored in a clean, dry environment, protected from direct sunlight and UV radiation and kept away from heat sources until filling. Proper storage helps to maintain the material properties, dimensional stability and functionality of the packaging system until use.

For our empty packaging, we recommend storage at room temperature and at a maximum temperature of 30 °C. Sufficient distance should be maintained from radiators, heating pipes and other heat sources; as a guideline, we recommend a distance of at least approximately one metre.

Where possible, the packaging should remain in its original transport or protective packaging and should only be opened shortly before use. This helps to reduce the risk of contamination from dust, dirt or other environmental influences. Packaging should also not be stored in the immediate vicinity of strong-smelling substances, chemicals or other potential sources of contamination.

During storage, care should also be taken to prevent buckets, cups and lids from being deformed by excessive stacking loads or other mechanical stresses. Damage or deformation may subsequently affect the correct fit of the lid and the leak-tightness of the packaging system.

We recommend using the supplied empty packaging for its intended purpose within 6 months of delivery and applying the FIFO principle (“First In – First Out”).

Important: These recommendations apply to empty packaging before filling. Different requirements may apply to filled buckets and cups depending on the filling product, formulation, fill quantity, temperature, storage period, stacking load and other process conditions. The suitability of the complete packaging system should therefore be assessed under the actual conditions of use and storage.

Storage of empty buckets, cups and lids – what should be considered?

Criterion Recommendation Why is this important?
Temperature Store at room temperature and preferably not above 30 °C. Prolonged or excessive exposure to heat may affect the material properties and dimensional stability of the packaging.
Heat sources Maintain sufficient distance from radiators, heating pipes and other heat sources; a distance of at least approximately 1 m is recommended. Local heat exposure can be significantly higher than the general room temperature and may cause deformation.
Sunlight / UV radiation Store protected from direct sunlight and UV radiation. Prolonged UV exposure may affect plastics and their visual or mechanical properties.
Cleanliness Store in a clean, dry and preferably dust-protected environment. This helps to reduce the risk of contamination before filling.
Protective packaging Where possible, keep buckets, cups and lids in their intended transport or protective packaging until shortly before use. This provides additional protection against dust, dirt and unnecessary handling.
Odours / chemicals Do not store directly next to strong-smelling substances, chemicals or other potential sources of contamination. This helps to prevent unwanted environmental influences on the packaging.
Stacking / mechanical loads Avoid excessive stacking loads, pressure and other mechanical stresses. Deformation may affect dimensional accuracy, correct lid fit and subsequently the leak-tightness of the packaging system.
Storage period Recommended: use within 6 months of delivery. Apply the FIFO principle (“First In – First Out”) wherever possible and avoid unnecessarily long storage periods.
Filled packaging These recommendations apply to empty packaging before filling. Suitable storage conditions for filled packaging additionally depend on the filling product, formulation, temperature, storage period, stacking load and other application conditions.

Practical recommendation

Empty buckets, cups and lids should be stored in a clean, dry environment, protected from light and preferably kept in their protective packaging until use. In particular, avoid direct sunlight, excessive heat, contamination and excessive mechanical loads.

For filled packaging, the suitability of the complete packaging system should be assessed under the actual storage, transport and application conditions.
