Isn't it better that it doesn't use as much paper?
Sadly, yes. Although problematic in terms of disposal, plastic bags win hands down in terms of resources used to manufacture and distribute them:
Wrap, the government-funded company set up to reduce waste, summarises the drawbacks of paper bags: while from a renewable source and biodegradable, compostable and recyclable, they require far more energy to make and transport than plastic, have less re-use potential and produce methane if dumped in landfill.
"Faced with the question of paper or plastic, the answer should always be neither," says Reuseit.com. According to a 2007 study (funded by US plastic bag manufacturers), it takes almost four times as much energy to manufacture a paper bag as a plastic bag. Paper-bag manufacture uses 20 times as much water as plastic and paper requires more energy to be recycled.

When it comes to whether the prog should be sent out in a plastic or paper bag, the admittedly counter-intuitive answer is that plastic bags are the clear winner. And that is before we even factor in this also means a great reduction in Soggy Prog Syndrome.
If you are concerned that you now have a rogue plastic bag on your hands and don't know what to do with it, then the answer is to recycle it. You'd need to find out what the specific type of plastic is but I'd suspect it must be similar to a plastic bag and a lot of supermarkets now collect old ones for recycling:

Where I live they don't even collect the PET plastic drinks bottles (although you can take batches of them to the local tip where they have facilities for collecting them) but there is no way to recycle yoghurt pots or plastic food packaging, and this needs to be addressed.
Hope that helps.
