TIPS ABOUT HANDLING AND STORAGE OF FILMS

POLYPROPYLENE Polypropylene does not require special storage conditions. In order to safeguard the mechanical features of the film and preserve the performance of the corona treatment, we recommend storing the rolls in their original packaging, at a temperature within 10°C and 30°C and with a humidity rate up to 60%. Avoid prolonged exposures of the film to direct sunlight or UV ray sources. In the event the roll is not fully used, we recommend storing it in its original packaging or cover it with a polyethylene bag, away from heat sources and direct sunlight. Especially during winter, we recommend approaching the rolls to the work site (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.

POLYESTER Polyester rolls must be stored in clean, dry and ventilated environments, 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, we recommend approaching the rolls to the work site (or storing them at room temperature) at least 24 hours before their use. We recommend removing the roll original packaging only before its use. For larger and heavier rolls, we recommend handling them using suitable equipment, in order to prevent deformations and damage the external layers. Anyway, it is suggested to use the film within 6 months from the delivery date.

METALLIC POLYESTER We recommend storing the metallic polyester at temperatures within 5°C and 30°C with a relative humidity rate up to 80%. The rolls must be protected in their packaging until their use. Provided that the metallic polyester can be subject to oxidation due to humidity, the rolls must be used as soon as possible once unpacked.

INFORMATION ON FILM STORAGE CONDITIONS POLYETHYLENE 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, we recommend approaching the rolls to the work site (or storing them at room temperature) at least 24 hours before their use. Attention, improper storage conditions can deteriorate the product and affect its physical-mechanical properties.

CELLULOSE ACETATE The mechanical properties of cellulose acetate are significantly different from polypropylene. This means that such a film must be handled with the utmost care. Specifically, the acetate film is a more rigid and less extensible material. Therefore, we recommend following the instructions below: 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 roll edges from being damaged. We recommend storing the cardboard box in the event the roll must be partially used. Once the box has been opened, the roll must be removed avoiding contacting its edges. Likewise, the roll must be placed or stored ensuring that it does not rest on its sides. In fact, small cut-outs, notches or dings on the roll can damage the film during the processing. Partially used rolls must be carefully repacked using the polyethylene bag, which must be tucked inside the core and kept suspended with a bar inserted in the core or using the original cardboard box. It is not recommended storing cellulose acetate rolls leaving them resting on the edges. When storing, Temperatures and Humidity values must not be too high. We recommend a Temperature range within 15°C and 25°C and a relative Humidity rate from 30 to 60%.

NYLON Nylon does not require special measures for its storage. It is sensitive to humidity; therefore, we recommend storing it inside its original packaging and possibly on a shelf and not on the floor. Keep it away from heat sources and protected from direct sunlight.

FOR ALL FILMS In order to ensure safety, we recommend to always handle the rolls using suitable equipment as safety gloves and shoes. Always consider the weight of the roll before moving or loading into the machine. We also recommend not leaving pieces of film on the floor, as they can 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 dimension or with a not particularly stretched winding can provide a “telescope” effect; therefore, always pay attention when handling them.
