Antistats for PE films
Low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE) are widely used in the food packaging industry due to their low production costs, heat seal-ability, high clarity, high elongation and softness. Complementary, high-density polyethylene (HDPE) offers puncture resistance, low stretch, reduced tearing and good moisture protection.
Most applications of these different polyethylene types require effective antistatic modification, in processing as well as for the final packaging performance.
Einar® 601 is based on a polyglycerol ester with a customized fatty acid chain length distribution, matching the specific needs of antistatic polyethylene food packaging applications: migratory properties even in high density PE, highest efficiency in binding water vapor molecules to form a conductive surface layer at lowest surface concentrations (down to 10mg/m2, corresponding to a coating thickness of 10nm).
Owing to the higher migration rates in LDPE and LLDPE, the recommended dosage levels of Einar® 601 for LDPE and LLDPE are as low as 0.1-0.5wt%. Due to the higher crystallinity of HDPE (>90%) migration is more demanding and higher dosage levels of typically 0.3-1.0wt% are required.
The exact, optimized dosage levels depend among others on the particular film structure (especially for multi-material, layered and laminated films), for which our technical team offers additional consultancy and further technical evaluation. Due to its excellent antistatic performance, Einar® 601 it is a highly effective, food-grade alternative to amines and amides.
The main benefits of Einar® 601 are:
- Highly effective and food-grade replacement for antistatic amines and amides
- Can be used for all polyethylene grades by adjusting the dosage level
- Compatible with all polyethylene grades regarding mechanical, optical and barrier properties
- Enables clean and dust-free polyethylene packaging in production and final application
- Food-grade alternative to amines and amides
- Globally approved for food-contact applications
