Linear Low-Density Polyethylene for Flexible Packaging

Linear low-density polyethylene (LLDPE) films used in flexible packaging face increasing demands for material efficiency while maintaining mechanical integrity. Current LLDPE films typically range from 25-100 microns in thickness and must withstand tensile forces up to 45 MPa while preserving barrier properties and surface characteristics for printing and lamination.

The core challenge lies in optimizing the polymer architecture and processing conditions to achieve thinner films without compromising strength, flexibility, and surface functionality.

This page brings together solutions from recent research—including advanced embossing techniques for tactile features, precision mold designs for surface patterning, and multi-layer lamination approaches that preserve mechanical properties. These and other approaches focus on practical manufacturing methods that enhance film performance while reducing material usage.
