UNIPrimer BioHybrid (Soon available)

UNIPRIMER FoodGrade BioHybrid is a universal, partially bio-based, water-based primer designed for food packaging made from paper, cardboard, natural fibres and thermoformed pulp. It improves the applicability, barrier properties and heat sealability of topcoat varnishes such as Varnipack FoodGrade, Varnipack FoodGrade BioHybrid and Aquabarrier FoodGrade BioHybrid.

Key properties:

• Effective barriers: Protects against mineral oil migration (MOSH/MOAH) in recycled paper.
• Sustainable composition: Partially bio-based (32% ±2%), free from BPA, APEO, formaldehyde, phthalates and heavy metals.
• Improves absorption and levelling: Reduces absorption and regulates the substrate for better application of finishing varnishes.
• Recyclable and repulpable: Compatible with compostable and biodegradable packaging.
• Regulation and safety: Complies with European Regulation EU 10/2011. Migration tests in progress for food certification.
• Free of hazardous substances: Safe product for transport and application, with no hazardous goods classifications.

Applications: Ideal as a primer for single-use food packaging, especially for paper, cardboard, thermoformed pulp and other vegetable fibre containers, improving the recyclability of the final packaging.

Application method: Applicable by flexography, gravure, anilox rollers, curtain, coating, industrial spray, airless or air-mix. Forced drying (hot air, IR) is recommended for best results.
