Film storage

Polypropylene does not require special storage conditions.

In order to preserve the mechanical characteristics of the film and the performance of the corona treatment, we recommend storing the rolls in their original packaging, at a temperature between 10 and 30°C, with a humidity rate up to 60%.

We recommend preserving the film from prolonged exposures to direct sunlight or UV ray sources.

In the event the roll has not been used internally, we recommend storing it in its original packaging or, alternatively, covering it with a polyethylene bag away from heat sources and direct sunlight.

Especially during winter, it is recommended bringing the rolls close to the work area (or storing them at room temperature) at least 24 hours before their use. Anyway, the film should be used within 6 months from the delivery date.
It is recommended storing polyester rolls in a clean, dry and ventilated environment, with temperatures up to 30°C. Avoid prolonged exposure to humidity and direct sunlight.

We also recommend keeping the product in its packaging until its use and protecting the partially used rolls.

Especially during winter, it is recommended bringing the rolls close to the work area (or storing them at room temperature) at least 24 hours before their use.

We recommend removing the roll from its original packaging only before its use.

For large and heavier rolls, we recommend handling them using suitable equipment, in order to prevent deformations and damages to the external layers. If the above storage conditions are complied with, the product can be used within 6 months from the delivery date.


We recommend storing the metallic polyester at temperatures between 5°C and 30°C, with a relative humidity rate up to 80%. It is recommended keeping the rolls in their packaging until their use. Provided that the metallic polyester can be subject to oxidation due to humidity, the rolls should be used as soon as possible after removing the packaging.


Protect the rolls from prolonged exposure to direct sunlight and UV ray sources. The material must be stored in a clean, dry environment at an average temperature of 20°C (max. 30°C).

We also recommend keeping the rolls away from emissions produced by diesel motors. Especially during winter, it is recommended bringing the rolls close to the work area (or storing them at room temperature) at least 24 hours before their use. Improper storage conditions may deteriorate the product and affect its physical-mechanical properties.


Cellulose acetate is significantly different from polypropylene in terms of mechanical properties. This means that this film must be handled with greater care. In particular, the acetate film is more rigid and less extensible. Therefore we recommend following the instructions below.
The rolls for lamination are usually packaged inside cardboard boxes, suspended by wooden squared timbers and protected by a polyethylene bag.
The material must be unpacked considering all those measures that can prevent the rolls edges from being damaged.
It is recommended keeping the cardboard box in case of partial use of the roll.
Once the box has been opened, the roll should be removed avoiding contact with the edges.
Likewise the roll should be positioned or stored ensuring that it does not rest on its sides. In fact, small cut-outs, notches or dings on the roll may damage the film during processing.
Partially used rolls must be carefully repacked using a polyethylene bag, which must be tucked inside the core and then held suspended by a bar to be inserted into the core or using the original cardboard box.
Again, it is not recommended storing cellulose acetate rolls by leaving them resting on the edges. During storage, temperature and humidity values must not be too high. We recommend a temperature range within 15° and 25°C and a relative humidity rate from 30 up to 60%.  


Nylon does not present any particular precautions regarding its storage. It is sensitive to humidity; therefore, we recommend storing it inside its original packaging and possibly on a shelf, not on the floor. Keep it away from heat sources and direct sunlight. 

In order to ensure safety, we recommend handling the rolls using suitable equipment such as gloves and safety shoes. Please take into account the roll weight before moving or loading it into the machine. We also recommend not leaving pieces of film on the floor, as they could make it slippery. Always keep the rolls away from heat sources and, if stored on a shelf, ensure that they are stable on it. Finally, rolls of a certain size or with a winding that is not particularly tight might cause a "telescope" effect. Therefore, always pay attention when handling them.
