I notice that Tesco's uses lots of that material for its ready-meal

Food trays can be a nightmare to recycle.
Plastics which can be cooked in, and film covers which are strong,
thin, transparent, and airtight, result in mixtures which can't be
separated for recycling, and contaminate other recycled plastic.
Many cardboard trays can't be recycled either because of the
waterproof coating on the inside. Aluminimum foil trays could be
recycled in theory, but many facilities can't separate out any
aluminimum other than cans, and it's not suitable for microwave-
ready meals.

However, the plastics backlash will probably reverse many of the
improvements in food shelf life over recent years, which have gone
a long way to reduce food wastage.


Undoubtably, reducing plastic waste WILL cost money. But given that were
figuratively ****ting on our own doorstep at the moment with our abysmal
recycling systems, I think we have to accept that we need to spend more on
on a better solution.

I don't think that can be assumed. Look at kamakatsu's recycling system.


Its really quite worrying to look at supermarket shelves and consider just
how many products just wouldnt exist without plastic packaging.

The amount of packaging is excessive though. Semi-rigid plastic dishes could be replaced with plastic film bags. Cardboard sleeves could be replaced with white plastic film, which can be one side of the bag.
