1. Don't expose to sun or heat (> 25°C), because the material could suffer changes in dimension. Store immediately after receiving it and stay in a fresh and shade place.

2. Don't hit neither drag the rolls.

3. Preferentially keep the rolls in vertical form in order to avoid to be marked in it surface. Maintain the part that is indicated in the label up in order to protect the fold.

4. At the moment of receiving the product, verify its dimension since later refunds for this reason won't be accepted.

5. Use first the older rolls.

Collapse of cardboard cores: it could be due to strikes received by the roll or to contraction of the material for exposition to temperatures higher to 25° C. 

Decrease of dimension of the film or distortion of the roll: Occasioned by exposition of the material to temperature higher to 25° C.

Rolls marked by pressure against another surface: Generally it don't represent problem unless it perforate the film.

Mistreated folded zone: This generally is caused for abuse or wrong handling of the rolls, for example, dragging of rolls, or by carrying out cuts or other works on the same. Here the problem is more serious than if it is made on the lateral part of the rolls, because practically the roll is affected in all their longitude.
