The strongest and most stylish multi-usable bags are the patch handled ones. The centered position of the handle makes the bag stay stretched when carrying something in it. The hanging of both upper edges of the bag is less than when carrying a soft loop handle bag. That is why people prefer the patch handle bag as better advertising product. On the other side these bags are really strong and most suitable when used in supermarkets. This kind of bag can be made by LDPE (low density polyethylene) or HDPE (high density polyethylene) as well.
