Smart copolyester-based heat seal coatings for anti-fog applications
Based on high-molecular weight copolyester technology, our anti-fog heat seal coatings:
- Improve product visibility and extend food freshness due to low oxygen transmission rate
- Increase package integrity with ideal seal strength and ability to achieve a smooth, peelable seal
- Reduce complexities due to reduced SKU needs to achieve both a bond and transparency, low blocking, shortened dwell time, and no refrigeration needed in storage
- Heighten sustainability due to compatibility with recycled tray stocks including PET, APET and RPET
Frequently Asked Questions about Anti-fog Heat Seal Coatings
How to improve transparency of lidding to pack fresh food?
Through the use of Heat Seal lacquer with the Anti Fog property for food packaging films. Once the package is in the refrigerator, the anti-fog effect will transform the tiny drops of water coming from the moisture contents in the food by a very thin transparent film which improves the clarity of the packages. This allows consumers to better inspect food and judge its freshness.
How anti-fog heat seal solves challenges in food packaging?
Anti-Fog Heat Seal Coating from Bostik provides anti-fog features without blocking, is able to seal at low temperature and through contaminated surface with proteins or blood.
What are the process recommendations from Bostik to use anti-fog heat seal?
Through the use of Heat Seal lacquer with the anti fog property for food packaging films. Once the package is in the refrigerator, the anti-fog heat seal coating starts migrating to the surface in the presence of moisture. Instead of forming tiny drops of water, the anti-fog creates a very thin transparent film of water condensate inside the package. This allows consumers to better inspect food and judge its freshness.
What is Bostik's position on sustainability in this anti-fog heat seal?
Internal anti-fogging additive leads to a number of advantages. Material source reduction and improvement of the transparency of the leading film with low heat seal temperature. It also increases the shelf life of food products and reduces food waste.
