Antifog

Fogging – the undesired formation of small water droplets on the surface of films – is a common problem when packing moisture-containing products such as fruit, vegetables, or meat in a tight container. While fogging makes packed food look less attractive, it can also damage sensitive products or reduce their shelf-life.

Ensure your customers always see your packaged content in the highest quality with SUKANO® Antifogging Agents. They reduce the surface tension of water, preventing fogging both on the surface and inside of food packaging. This durable and homogeneous antifog effect significantly improves the shelf-appeal of refrigerated food, presenting it in a more attractive manner, all without the need for coatings.

The Antifog Compounds for PET applications enable the transition to recyclable mono material packaging solutions and are suitable for sealable lidding films and trays.

Our Antifogging Compound eliminates the requirement for coatings as a secondary processing step and enables easy handling. Due to its internal addition, the effect is homogeneous and more durable than coatings. 

UV Content Protection for Transparent Applications

Polymers do not protect against the harmful effects of UV radiation, so there is a need for additives to absorb these damaging rays.

The SUKANO® UV Content Protection masterbatches bridge the gap in UV absorption for your resin, ensuring the protection of the final product. By using our UV masterbatches, you safeguard sensitive transparent applications, such as packaged food, cosmetic containers, or pharmaceutical products, from harmful light. This preserves the content’s integrity and appearance.

We offer a diverse UV masterbatch portfolio tailored to different protection levels, polymer carrier compatibility, and end applications.

With our UV Content Protection masterbatches, you prevent loss of color, yellowing, and maintain the appeal of your shelf-items. Additionally, you can ensure freshness and prevent flavor changes in food products.

Light Barrier for Dairy

UV and visible light in the 250-700nm range leads to the loss of nutrition and flavor in dairy products. PET does not absorb these harmful wavelengths on its own.

Protect your dairy products from visible light with SUKANO® White PET masterbatch portfolio specialized for ESHL and UHT mono and multilayer PET milk bottles. Our Light Barriers safeguard dairy applications without compromising efficiency during production or altering visual or functional properties. They provide protection against specific wavelengths and include grades with oxygen barrier properties.

Block light transmission and preserve the freshness, nutrition, vitamins, and flavor of your dairy products with SUKANO® Light Barrier masterbatches.

AA Scavenger

Acetaldehyde (AA) is formed as a by-product at high temperatures during the production or recycling of PET. Even at very low concentrations, AA imparts an unpleasant taste, which can significantly affect the flavor of neutral beverages, particularly mineral water.

Your secret weapon for fresh beverages with original taste: SUKANO® AA Scavenger. The masterbatch is integrated into the polymer during injection molding of bottle preforms to neutralize AA molecules in the bottle walls. While it successfully reduces the AA concentration in beverages and resolves taste and odor concerns, recyclers and converters using recycled PET may also enjoy the benefit this additive offers.

Our AA Scavenger exhibits a no-slip effect, ensuring stable processing and high productivity, reducing AA presence in the final application.

Enhancing Barrier Properties Through Collaboration

Leveraging our long-term experience in polyesters, our in-house laboratory, and renowned partners, we develop additive combinations that enable durable and high-performing product solutions.

PET Antifogging Compound

In a joint development project with Emery Oleochemicals, a leading global manufacturer of natural-based chemicals, we have developed the first PET Antifogging Compound designed for direct food contact PET packaging.

Formulated to be used at 100% in cold applications, it prevents fogging on packaging surfaces. Its robust performance ensures the antifogging function remains effective even after orientation at various ratios. Antifogging for PET is a challenging application, but by combining our expertise, we successfully addressed processing challenges associated with adding antifogging agents to PET.

Light Barrier for White Opaque PET and rPET

Working closely with the top-tier rPET supplier, Dentis Recycling Italy, we develop specialized masterbatch grades that improve bottle whiteness and maintain essential light barrier properties when using up to 50% RPET Food Grade REPETER® for ESL, UHT in mono- and multi-layer applications.
