How masterbatches enable safe and efficient packaging solutions

In today’s plastics industry, cost-efficiency, safety, and sustainability are no longer optional – they’re essential. Brand owners and plastic converters are under increasing pressure to deliver high-performance packaging solutions that meet regulations, support circularity, and align with environmental goals.

Why masterbatches matter
Plastics compounders and converters face a common challenge: how to add functional properties to base polymers while maintaining efficiency, safety, and cost control. Achieving precise dosing and homogeneity with individual powders, pastes, or liquids can be complex and time-consuming.

For masterbatch producers, this creates both a challenge and an opportunity; how to provide additive solutions that combine technical excellence with responsible sourcing and circularity. Pelletised additive masterbatches solve this problem. By combining additives into a single, easy-to-handle format, they simplify dosing, reduce handling risks, and ensure consistent performance. For masterbatch producers, this is an opportunity to deliver value-added solutions that meet the needs of converters and brand owners.

The Einar® advantage
Palsgaard’s Einar® range of plant-based, food-grade additives is designed to help masterbatch producers stand out. Derived from renewable vegetable oils such as palm, rapeseed, sunflower, and coconut, these additives offer a bio-based alternative to conventional fossil-based additives like amines and amides—without compromising performance.

KEY BENEFITS OF EINAR® POLYMER ADDITIVES:

Regulatory readiness and food-contact compliance – ideal for sensitive applications
Low dosage efficiency – effective at concentrations as low as 0.1–0.4%, helping optimise cost-performance
Support for circularity – enabling recycling and thinner packaging without compromising functionality
Fatty acid esters from renewable vegetable oils

Why use masterbatches with Einar®?
As Einar® Polymer additives are neat additives, achieving a consistent dosing at very low concentrations can be challenging for converters. Masterbatch producers bridge this gap by delivering ready-to-use pelletised concentrates that:

Ensure accurate dosing and homogeneous additive distribution.
Improve production safety by reducing dust and spillage.
Offer flexibility for film extrusion and injection moulding.

By incorporating Einar® additives, masterbatch manufacturers can strengthen their portfolio with high-performance solutions that balance cost with safety and renewable sourcing.

Application areas

ANTI-STATIC SOLUTIONS

Einar® 601: A proven plant-based alternative to ethoxylated amines, delivering long-term anti-static performance in PE films and foams at loadings as low as 0.1–0.4%. Ideal for food packaging and electronics, even under low humidity conditions.
Einar® 401: Developed for impact copolymer PP, offering anti-static performance and improved mould release. Outperforms traditional GMS/EA systems in static decay tests.
Einar® 411: Designed for PP films, including random and block copolymers. Performs reliably even in thin sealing layers of coextruded or laminated films.

ANTI-FOG SOLUTIONS FOR PE AND PP

Einar® 611 (PE) and Einar® 618 (PP): Preventing fogging in chilled and hot food packaging. Maintain transparency in cold storage and microwave-ready applications.
Einar® 422 and Einar® 406PL: Hot-fog resistance in microwaveable and hot meal packaging on display.

Supporting circularity
As packaging moves towards mono-material designs and thinner films to improve recyclability, achieving effective anti-static and anti-fog performance becomes more demanding. Einar® additives help masterbatch producers deliver solutions that meet these evolving requirements –while supporting resource efficiency and keeping packaged food fresh for a longer time.

This commitment to circularity reflects Palsgaard’s broader sustainability vision. Through our Heart Working Commitments, we integrate environmental responsibility into every aspect of our operations, ensuring that the solutions we offer today contribute to a more sustainable tomorrow.

All **Einar®** polymer additives are plant-based and food-grade and safe enough to eat as they are inherently food ingredients.
