Case Study – Safety First For Hospitals!: Ready to cook meat products can be transferred to hospital ovens without handling any raw ingredients – a basic rule of hygiene in these highly sterile environments. This lasagne product made for hospitals uses a multiportion smoothwall tray. A primary advantage of these large trays is that they offer much greater rigidity than an equivalent sized plastic tray, especially when removing them from an oven and for serving purposes. Of course these one-time use aluminium foil containers are fully recyclable – while offering the highest standards of hygiene and safe handling and are a very cost effective option too!
