Flexible package extrusion Laminating is a high-volume manufacturing process where raw plastic resins are melted, mixed, and formed into continuous, thin sheets or films. These films are the primary material used to create a vast array of flexible packaging products, from simple plastic bags to complex multi-layer food pouches.
The core principle is to push molten polymer through a die (a specially shaped opening) to create a uniform, two-dimensional structure with a specific thickness and width.
A flexible package extrusion process involves melting a polymer (commonly polyethylene (PE), polypropylene (PP), EVA, or other resins) and extruding it in a thin film layer that is directly applied onto a substrate.
Purpose: To create laminated or coated structures that give packaging strength, barrier protection (against moisture, oxygen, or grease), printability, and sealing ability.
Applications of Flexible Package Extrusion:
Food packaging (snack packs, frozen food bags, beverage cartons)
Industrial packaging (cement bags, chemical sacks, protective wraps)
Medical and hygiene packaging (sterile wraps, disposable product packaging)
Flexible Package Extrusion Key Advantages of the Process
Lightweight & Source Reduction: Uses far less material than rigid packaging (like bottles or tubs), reducing waste and shipping costs.
Customizable Performance: Coextrusion allows engineers to "dial in" exact properties (barrier, strength, seal) for a specific product.
Cost-Effective: Very high production speeds and continuous operation make it economical.
Design Flexibility: Enables innovative package shapes like spouted pouches and easy-to-open features.
