Smart benefits

Our smart food packaging seals are specially designed to increase efficiency across all stages of operation. Visual indicators on our cold seal coatings clearly signal press-ready material and allow pattern registration without the use of dyes or pigments. 

Bostik cold seal technology is formulated for converting at higher speeds to reduce the chances of streaking, ghosting, and foaming – meaning faster processing and less waste. 

Bostik Turbo-Seal ® can be used in conjunction with high-speed horizontal form-and-fill packaging machines. This can greatly improve scope for profitability overall, as HFF systems deliver higher sales per hour of output and require less maintenance. 

Our cold seal products also give you lower cling and smoother unwind release due to an enhanced anti-blocking system. This smart innovation means more consistent packaging performance and sealability, plus stronger seals. 

Because of their superior adhesion and cohesion strength, our cold seals result in fewer “leakers” compared to traditional heat-sealed packages, providing reliable freshness with hermetically sealed packages. Their strong moisture resistance also means a longer shelf life.

Cold seal flexible packaging: availability

Bostik Turbo-Seal ® solutions are available in the Americas, EMEA and Asia.

Food packaging materials

Bostik cold seals utilize rubber-based adhesives, and are perfect for food product applications that require consistent seal strengths on high-speed horizontal form-and-fill packaging machines. Applications can range from baked goods and frozen treats to confectionery items, which often use more varied size wraps or complex overwraps for multiple candy bars. 

Our cold seal products also contain coatings specifically designed for hermetically sealed packages, such as granola bars, cereal bars and coffee packaging. 

Medical packaging

We manufacture synthetic, water-based acrylic solutions for medical packaging that are non-allergenic and are specifically designed to withstand the rigors of the medical packaging industry. Our cold seal coatings provide superior sealability and aging performance for several pharma packaging applications, including sterilizable and non-sterilizable overwraps for bandages and various other medical devices.
