Liners to cover equipment after sanitation?

Hello all, we are a bakery in Canada. Does anyone know where we can find food grade liners (in rolls) to cover our equipment after sanitation that are cost effective? We have found large bags but they do not cover  the equipment completely and we have to use several and cut them to work. Also, has anyone used non-food grade liners to cover equipment after sanitation and is this acceptable against SQF standards? Thank you in advance.

The are used for 6foot by 6 foot cardboard boxes and will do the trick for you. They come on a perforated roll, so you can tear off what you need and install the hangers on a wall so nothing touches the ground

We recommend trying to get either blue tinted oven rack covers or perforated blue coloured pallet top sheets on a roll that work well for covering equipment. Also use a pallet cover that look like a big shower cap ie. elastic sides also in blue colour that are used to cover the topes of pallets and drums etc.
