Among the most valued technologies in materials processing, multilayer polymeric foils extrusion is capable of revolutionizing packaging and industrial applications. In the engineering and manufacturing of high-performance extrusion and calendering machinery, BG Plast is a benchmark through experience and innovation.
What is multilayer extrusion?
Multilayer extrusion is a process in which multiple polymers are combined to produce sheets and foils with a layered structure. The result is a material with improved physical and functional properties, such as barrier capacity, mechanical strength and aesthetics. Our extrusion and calendering machines excel in producing high-quality multilayer materials that meet diverse industrial needs.
BG Plast extrusion and calendering machinery enables the production of multilayer foils with thicknesses ranging from 0.15 to 1.8 mm
The role of multilayer extrusion in packaging
Food packaging: how to improve freshness and shelf life
Multilayer foils are indispensable in the food packaging industry. BG Plast’s advanced extrusion technology allows barrier layers such as EVOH (ethylene vinyl alcohol), which significantly reduce oxygen permeability, to be incorporated into production. This feature helps preserve food freshness, prevents contamination and extends shelf life-a key requirement in today’s supply chains.
Pharmaceutical applications for maximum precision and protection
In the pharmaceutical industry, ensuring the integrity of drugs and medical supplies is critical. Multilayer extrusion offers unparalleled protection against moisture, light and contaminants. Our systems make it possible to create highly durable and customizable multilayer foils that are ideal for blister packs and other pharmaceutical packaging needs.
Industrial applications of multilayer foils
Multilayer extrusion goes beyond packaging to a variety of industrial applications. BG Plast’s lines produce custom-made sheets and foils for:
– Construction. Acoustic and thermal insulation solutions.
– Automotive. Production of components with increased mechanical strength and light weight.
– Electronics. Creation of barrier materials for sensitive electronic components.
Materials that are extruded in this way are designed to meet industry-specific requirements, offering superior performance and cost efficiency.
Customization: tailor-made solutions with the highest precision
BG Plast is the ideal partner for industries looking for efficiency and accuracy because of our ability to customize extrusion equipment to the customer’s specific needs.
