How to Choose a Food Container Set for a Retail Range
Capacity spread, shape, colour coding and footprint decide whether a container set sells. A buyer's checklist with the Welfan items mapped against it.
Start with the capacity spread
A container set earns its shelf space by covering the volumes a household actually uses. In practice that means something around 0.2 L for condiments, around 1 L for a portion, and at least 3 L for leftovers or batch cooking.
Across the Welfan sets the spread runs from 0.1 L in item RB-001 to 4.9 L in item RB-003. If your range needs one set that covers the widest ground, RB-003 is the one to look at. If it needs a compact set for small kitchens, RB-001 is.
Then decide the shape
Round bodies pour and rinse more easily, which matters for soups and sauces. Rectangular and square bodies use shelf and fridge depth better.
The rainbow family is offered in all three: RB-003 round, RB-001 square and RR-002 rectangular. That lets a buyer choose shape without leaving the family or changing the colour story.
Check whether the set nests or stacks
These are different behaviours and they solve different problems. Nesting saves cubic volume in the carton and the cupboard when the set is empty. Stacking saves shelf space when the containers are full.
Item KS-005 is the clearest stacking example in the range: all three bodies share a 20 x 15 cm base and differ only in depth, so a loaded column does not overhang.
Count the pieces against the price point
Three-piece sets sit at the entry price, seven-piece sets in the middle, and the eight-piece KS-006 at the top of the range.
KS-006 is also the only set that mixes round and rectangular bodies and includes three 175 ml pots, which makes it the natural choice for a boxed gift programme.
Confirm what is not yet documented
Colours, carton quantities and packing are confirmed per order rather than published. Ask for those in writing before artwork, and quote the item number when you do.
