I leave a picnic bag in the car with six plates, cups and cutlery. It's all reusable (after washing). This means that a family lunch out can be larger packets divided up rather than lots of individual packaging which for 6 people, can fill a bin!
I always carry cloth bags for shopping, stored in the car.
I reuse packing from postal deliveries.
I print and stick barcodes directly to lose fruit and veg. They don't need an extra plastic bag.
I take reusable cups if I'm having a take away coffee.
I use half measures of washing powder with a tablespoon of washing soda if needed for soiled items.
We share baths.
I clean with recycled cloths, hot water and washing up liquid.
We recycle responsibly, a shocking amount each fortnight, about 350 litres. Making it around 700 litres a month. Luckily our recycling collection will take extra, if left open beside the recycling bins.
This surely demonstrates that packaging is a problem, but at least it's being reused/ recycled.
