Cartons are identified with an irradiation indicator. Always check that the irradiation indicator dots (indication the bag aseptic conditions) are of the correct colour, which is red. Never use boxes with a yellow dot (bags are not irradiated). In case of doubt, please contact your supplier in writing within 7 days after receipt of the bags.
The dimensions of the bags are proportionate to the size of the outer container. The dimensions of the bags will have to be determined by suppliers’ technicians: the internal size of the outer container must be advised upon placing the order for aseptic bags. The inner side of the outer container must be free from cutting edges, scratches or impurities, in order to avoid damage to the bag (cuts, holes) during filling and transport operations.
Handle the aseptic bag with care during the filling operation ensuring the bag is correctly held by the pincer/clamps to minimise the strain applied to the fitment (see schematics attached). During filling, the bag film should not be in direct contact with hot parts on the fill head. Avoid steam or hot condensate from flowing on to the bag film during the filling process.
The container lift system or fill head movement should ensure that the product load is supported by the container during the complete filling process. The establishment of the correct sequence of outer container lift or fill head movement steps should minimize the weight carried by the fitment with the pincer/clamp only releasing at the end of the cycle. It is particular important to check that the closure is correctly placed in the spout. After filling, carefully fold the empty corners of the bag towards the centre, taking care to avoid creases and smoothing the surface. Make sure that the filled bag is completely supported by the outer container.
Avoid the introduction of any foreign bodies which may damage the aseptic bag. Take care not to pinch the bag with the cover when closing the outer container. The cover of the outer container must close tightly. It is important to keep a record of the production date, the filling head number, the temperature of the filling head and the bag number going with each outer container. This will avoid handling of all outer containers in case of accidents, because it will enable you to identify and to sort out the claimed lot, thus saving time and money and allowing immediate control and evaluation of eventual damages. IMPORTANT: For Liquid Product Bags Avoid head space between the filled bag and the top cover of the drum or other outer container. Should head space exist, it should be completely filled in order to prevent excessive movement of the bag within the outer container. When the viscosity is less than 500 CP (at 200°C, BROOKFIELD) it is necessary to consult the supplier’s technicians.
