Regulatory & Compliance
- Certifications & Compliance
- Chemical Inventories
- Food Contact Regulations
SEAL Family films comply with Mercosul, ANVISA, FDA (Food and Drug Administration) and the European Community legislations for applications involving direct contact with food. Full details are provided in the Declaration of Conformity. Customers intending to use SEAL Family films for applications intended to come into contact with food should request a copy of that document from POLO Films.
Storage & Handling
- Storage
All products are stored and transported in dry, covered and clean environments. It is recommended that storage and transportation take place at temperature around 30°C and 60% relative humidity.
If the temperature and humidity are not as recommended, the following issues may occur
- Decreased level of surface treatment, leading to printing and/or lamination difficulties
- Decreased film transparency
- Too low CoF, making processing and machinability difficult.
- BOPP films are recommended to be kept at operating room temperature for 24 hours before use.
- Shelf Life
6 months
