The Crest Dacron bags are made of a net of 100% polyester and with 8 mm holes. These bags are absolutely unshrinkable and have excellent temperature resistance. They are designed to be machine-washed directly with the linen they contain. The bags are available in various colours and equipped with a range of fasteners (like for example: NF button sewn directly onto the bag, spring buttons, pins, and rubber laces). Also available in a zipped version with an identification label sewn onto the side. This bag is ideal for separating personal items (of hotel guests, or of hospital patients, for example) to be sent to the laundry.
