I used to work in a factory which made plastic packaging. After the film was extruded it was trimmed so the roll was nice and neat, and the trim would be repelletised and go straight back into the hopper.
If the operators messed up a roll for whatever reason they'd cut it off the core and shove it in a baler; the bales would then go into a recycling machine which melted it down and turned it back into pellets so it could be reused.

With this in mind I struggle to see why plastic packaging can't or isn't recycled after it's had chips, carrots, dog biscuits or compost in it.
 
Have friends who work as environmental scientists and have taken part in some of the defra consultations...
amongst things that are going to change according to the boffins who advise the officials are:
- Black plastic.... its a mix of the recycling plants not being able to identify it against the conveyor belts on teh sorting lines and sometimes its a mix of nasty plastic leftovers... so they are thinking of at some stage banning black plastics... supermarkets not happy as it makes the meat look pretty apparently and is cheap..
- yoghurt and similar pots will have to be made of plastic and not polystyrene so it can be recycled.
- polystyrene itself is on borrowed time and will at some stage be the devils work like straws..
-even bags for life will eventually go.. people will use fabric bags made from recycled fibres... paper bags are surprisingly worse environmentally than the single use plastic ones! due to energy needed to make and process. its a progressive step by step thing..
- essentially at some point in the future all food packaging will have to be 100% recyclable no exceptions... no more film wrapped grapes..
- They are looking at all takeaways and ready meals to use the plastic substitutes such as wood pulp and starch based trays and straws.. Iceland have already announced this change...
- crisps and confectionery etc ...will have to have recyclable or biodegradable wrappers and not that weird foil laminate they use..
- they are considering whether they can force all fruit and veg to be sold loose or in 100% recyclable non plastic packaging...
- the bottle deposit scheme could screw council recycling schemes as they sell what they collect into the market for reprocessing, but what they are thinking is that the councils would collect the bottles that are returned to stores and then sell them as now as they already have local collection facilities, the council keeping the money and it saves stores/drinks firms from having to collect or move them itself.
- even things like toothbrushes.. disposable razors and toiletries are in the cross hairs... take lynx those bottles cant be recycled due to being black plastic so that will change... razors can according to bic be changed to a starch based polymer without anybody realising at minimal cost..

give it ten years and we will barely give any of this any thought.
