As demands for increased package end-use performance and reduced environmental impact rise across the flexible packaging industry, it’s critical for converters or film producers like you to understand the role the right adhesives play in your ability to address them.
However, at Bostik, we understand your equipment typically determines what capabilities you can provide for both food and non-food applications. Therefore, it’s a good idea to know how Bostik's cold seal, heat seal, reseal and laminating adhesive solutions can still help you meet those demands regardless of equipment.

Where Our HEAt Seal Solutions are Used:
Heat seal adhesive coatings are capable of withstanding microwaving and steam sterilization.
If your packaging is protecting high-temperature products...
Consider:
While you can purchase film with heat seal coatings that film suppliers extruded, you can also custom formulate our coatings to better control the peel force via low coat weight and application pattern. This helps you achieve optimized performance needs.
Customized formulations
Our heat seal coatings can also offer anti-fog capabilities directly within their formulation. In addition to providing sufficient seal strength, they help mitigate water droplets from forming on the package lidding, which increases package transparency.
Anti-fog capabilities
Our heat seals protect packaging that contains products with high-acidity or chemical content, enabling packaging longevity and usage for sauce or condiment applications.
Chemical resistance
Our heat seal coatings can withstand high heat from microwaving and steam sterilization. This performance capability enables versatile application usage for food and medical applications as well as shrink labels.
High temperature resistance
Our water-based and solvent-based heat seal adhesive coatings offer:
HEAT Seal
While the specific dual functionalities can vary depending on your performance needs, our heat seal coatings allow your packaging to use about 30% less material compared to rigid claim shell packaging* as a result of offering two or more performance capabilities in one product.
Dual functionality
You can increase functionality in films with our heat seal adhesive coatings through gravure coating, flexographic printing and other techniques.
By adding about a 1mm x 10mm strip of heat seal coating to the inside, you can properly secure shrink labels in place to reduce waste potential and increase brand awareness.
Whether your heat seal package has a label...

Where Our RESeal Solutions are Used:
Bostik’s reseal offers anti-blushing capabilities to allow a package to opened without altering the lid graphics.
If you’re packaging material with high-moisture content...
Consider:
Our reseal solutions offer customizable peel performance, such as high or low peel. This helps you tailor the performance capability to the end-use package application.
Able to be customized
Their high performance capabilities allow the packaged to be resealed package more than ten times* while keeping food fresh. This in turn helps reduce food waste and decrease plastic material usage by 30%* compared to clamshells.
Able to reduce environmental impact
Our solvent-based coatings offer transparency for high-moisture products without water whitening, which improves end-use package visibility.
Able to eliminate blushing
This allows you to achieve your desired peel strength.
Formulated for press-ready, coat weight customization
This performance capability allows you to expand your packaging options for food and non-food products.
