Calendering - rigid sheets

The activity generating the emissions is calendering, rigid sheets. The reference product is calendering, rigid sheets. This is delivering the service of calendering, rigid sheets. Calendering is a speciality process for high-volume, high quality plastic film and sheet, mainly used for PVC as well as for certain other modified thermoplastics. The melted polymer is subject to heat and pressure in an extruder and formed into sheet or film by calendering rolls. The temperature and speed of the rolls influences the properties of the film. Calendering allows speciality surface treatments of the film or sheet such as embossing or enhancing the physical properties or in-line lamination. In the service of calendaring, 1 kg of this process corresponds to 0.997 kg of calendered rigid plastic sheets. The converted amount of plastics is not included into the dataset. This service should be used along with 1 kg of thermoplastic material, usually PVC. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity. Please refer to the ecoinvent documentation here for full details: https://ecoquery.ecoinvent.org/3.11/cutoff/dataset/793/documentation.
