What is a Flexible Laminate..?
“A flexible film laminate is a combination of
two or more layers of different films
bonded together to form a multi-ply
structure.”

Why Laminate?
There is no perfect, universal packaging material
Laminates assemble materials with individually desirable properties to create an optimum material
Laminate: A product made by bonding together two or more materials

Laminate Properties
Sealabilitymost flexible packaging is heat sealed
most heat seals are polyethylene based
other polymers used more critical applications

Why Flexible Laminates..?
It combines the properties of individual
layers and gives options to develop a
packaging structure that suits the exact
requirements of the product to be packed.

Types of Lamination Process
1. Adhesive Lamination
- Adhesive is applied between the two layers of substrates which are to be
bonded.

Types of Lamination Process
2. Extrusion Lamination
- Extrusion coating where polymer film is extruded on a single web (2-ply laminate) or between 2 webs (multi-ply laminate).

3. Heat & Pressure Lamination
- Usually adopted for Aluminium foil. Readymade film is pre-heated and combined with foil to form a composite.
