We have started delivering material from our big bags that we collect and now it is the third delivery to the same recipient, so it bodes well. We have had to repack the material from sacks that are not quite correct, so of course we use our own big sacks produced by rPP.
Of course, you can buy these sacks as well and then boast that you have a durable duffel bag in a double sense.
You can find more information about the big bags via this link. The price is based on a unit price, so if it is of interest to look at larger volumes, Accon AB will arrange quotations for you.
