- Bag in boxes
Available to order, these have original Vitop taps:-
The 20 litre
carton needs some adhesive tape to assemble it properly but the smaller sizes can be used
without tape.
5 litre 3-layer polythene bag with Vitop tap @ £0.90 each; box of 300 @ £0.76 each
special carton (manilla-brown or white) @ £0.52 each
10 litre 3-layer polythene bags with Vitop taps @ £1.19 each; box of 200 @ £1.00 each

special heavy duty carton (white) @ £1.43 each

Notes on filling:-
- After assembling the carton and inserting the bag, the bag-in-box is placed (with the tap at the top) on a set of accurate weighing scales. Filling is carried out through the bag collar (with the tap removed), the fill-weight corresponding to the volume (5, 10 or 20 litres) having first been calculated according to the specific gravity of the liquid at 20 °C.
- I suggest getting a thin sheet of aluminium or rigid plastic, to lay on top of the carton when filling, with a cut-out to allow the sheet to slide under the collar flange, giving extra support and avoiding any splashes being absorbed by the carton.
- It is sometimes suggested that the bag should be filled (using a special stainless steel support) outside the carton, but a large bag could possibly tear when not supported by the box, then afterwards lifting a full 20 litre bag into the box is not easy.
- After filling, the BiB tap must be pushed fully home into the bag collar, with the tap
flange flush with the bag collar flange (the 'third click' position) to
ensure a secure, permanent seal. This is not easily done by hand.
There is a simple tool (special pliers) that ensures a well fitted tap, for £59.
The third click is a bit difficult to achieve just by using fingers, but not impossible -
there is some danger of bursting the bag. Having said that, 2 clicks is probably secure enough.
