DOW DNDA-8320 NT 7 LLDPE pellets Advantage
- Food contact safety grade plastic raw materials. DOW DNDA-8320 low-density linear polyethylene meets food contact standards and has obtained the US DMF drug contact standard, US FDA 21 CF177.150(c)(3.1a), Canadian HPFB, No Objection (with limitations), and EU EU 10/2011 multiple plastic compliance requirements. This material is very safe for food contact applications
- Easy to process, DOW 8320 is a high flow lldpe material for injection molding. It is easy to manufacture thin-walled, complex lldpe products while maintaining good production efficiency.
- No additives LLDPE material, DOW 8320 does not contain slip agents and molding aids. This kind of lldpe granules meets high-level food safety certification standards and is suitable for use in areas with higher environmental requirements.
- Low temperature-resistant lldpe pellets. Compared with the same grade of lldpe granules, DOW 8320 has higher low-temperature resistance and can still maintain excellent mechanical properties and appearance at lower temperatures.
