What Industries Use Custom Plastic Extrusion

With the advent of advanced extrusion technology, the packaging industry has undergone a major transformation. Extruded products play a vital role in creating durable, flexible and high-performance packaging solutions. From food packaging to industrial applications, extrusion coating and laminating machines have revolutionized production efficiency and product quality.

This article explores key application cases of extruded products in the packaging field and highlights the role of cutting-edge machinery such as the WSFM Shaftless Automatic Extrusion Coater, SJFM Extrusion Laminator and GSFM Automatic Extrusion Laminator in shaping the development of the industry.

Key Application Cases of Extruded Products in Packaging
 

1. Flexible Food Packaging

Extrusion coated films are widely used in food packaging to enhance barrier properties against moisture, oxygen and contaminants. Common applications include:

Snack bags (chips, nuts)
Frozen food bags
Liquid packaging (milk, juice)

Equipment like the WSFM Shaftless Automatic Extrusion Coater ensures high-speed, precise coating for superior sealing and durability.

2. Disposable and Industrial Packaging Applications

Extrusion lamination technology plays a vital role in producing high-performance packaging for various disposable and industrial uses, including:
 

Disposable paper cups (oil-proof and waterproof coating)
Fast food boxes and waterproof paper bags
PP woven bags and non-woven stand-up bags
Baby diaper packaging
Cement bags and agricultural mulch membranes
Roof radiant barrier products
 

SJFM extrusion laminating machines excel in producing multi-layer composites with precise thickness control, ensuring durability and functionality for these different applications.
 

3. Paper, Non-Woven Fabric, and Aluminum Foil Composite Films
 

Extrusion lamination technology is widely used to produce high-performance composite materials, including:  

Paper-based laminates (for moisture-resistant packaging)  
Non-woven fabric composites (used in medical and hygiene products)  
Pure aluminum foil composite films (for superior barrier protection)  

The GSFM Automatic Extrusion Lamination Machine ensures strong bonding, uniform coating, and enhanced durability, making it ideal for advanced composite applications in food, medical, and industrial packaging.
