A packaging system for individually packaging a succession of products, especially poultry, into bags, for example quad seal bags. The system comprises a packaging apparatus, a weighing apparatus and a printer. The weighing apparatus is located adjacent the packaging apparatus such that the weighed product is the next product to be packaged by the packaging apparatus. The printer prints information relating to the weight of the weighed product directly onto the packaging material for the weighed product, or onto a label for the weighed product. Since the product is weighed just before being packaged, it is ensured that the information printed onto a bag relates to the specific product in the bag.
