Buy a paper towel what's easier. This is however much more technical than it suggests. At first it is common to speak of "paper" napkin except that even if the raw material used in the context of recycled products old "papers", the raw material is cotton wool. A paper towel is characterized by several features:
Size of the paper towel
The format of the paper towel is always unfolded. Namely when talking about a 30x30 paper towel it means it is 30x30 cm when unfolded. Its folded format obviously depends on the shape of the fold. If it's a 4 fold, its folded format will be 15x15. There are now many variations that range from the cocktail napkin (20x20 unfolded) to the pre-folded towel through the sachetto towel that also serves as a cutlery pouch.
Number of folds of the towel
The number of layers of paper commonly called the number of folds. Thus a 1-ply paper towel will have a thickness of paper, 2 plies 2 plies ... The more pleats in a towel, the thicker it is and therefore absorbing.
Attention we speak well of cellulose wadding towel and no napkin that is a thick but in a material type Airlaid whose weight varies from 55 to 120 grs / m2 depending on the products.
Paper weight
The grammage of the paper which is actually cotton wool. We are talking about a paper towel but it is actually a misnomer. A purist talks about wadding towel. The grammage is expressed in grams per m2. It varies from 16 to 20.
Quality of the wadding and therefore the "paper"
We must then take into account the quality of the wadding (so the raw material). The paper towel can be made from pure cellulose pulp or recycled paper. In the context of recycled paper, it will be necessary to pay attention to the quality of de-inking and other processing operations of the old paper used to manufacture this raw material that is recycled wadding. Indeed, if it remains heavy metals (ink and other printing substances) on a product that will come into contact with the mouth of users, this is clearly important in terms of safety.
Paper napkins are also available in different colors. Here too pay attention to the type of ink used. A food ink is needed.
Paper towel and environment
The environmental concept is now very present with more particularly the European label Ecolabel which some products can benefit.
Also beware of towels that are too white and whose manufacturing process uses and abuses optical brighteners.
As you can see, a paper towel is also a risk and this is not mentioned much.
