Cold seal

Tecnology description

Cold seal packaging is normally manufactured from laminated structures designed according to the product, required barrier, and packaging speed.

Structure and materials

Structures may include materials such as:

Biaxially oriented polypropylene, BOPP
Polyester, PET 
Paper or cellulose-based materials
Metallized films
High-barrier films
Cold seal coating applied in specific areas
Inks and varnishes compatible with indirect contact or food applications, depending on the requirement

The system can be developed with:

Surface or reverse printing
Lamination with compatible adhesives
Registered cold seal coating
Adhesive-free or coating-free areas according to design 
Moisture, grease, aroma, or oxygen barrier properties, depending on the application

Key performance benefits

Helps protect temperature-sensitive products 
Supports high packaging speeds
Reduces cycle times compared to conventional heat
sealing 
Improves efficiency in flow pack or horizontal wrapping
lines 
Enables clean and consistent seals when properly applied 
Suitable for individu

Typical applications

Chocolate bars
Cereal or protein bars
Ice cream and frozen products 
Individual snacks 
Cookies and confectionery 
Heat-sensitive products 
Ready-to-eat foods
High-speed flow pack packaging
Products where heat sealing may affect texture, shape, or stability

Blue Pack Advantage

Blue Pack Solutions develops cold seal structures designed for high-speed lines, heat-sensitive products, and applications that require efficient sealing, strong presentation, and consistent shelf performance.
Our approach considers the product, packaging speed, required barrier type, coating
application area, and real production, distribution, and display conditions.
