Extrusion Coating Machine
Extrusion Coating Machine
Extrusion coating machine is a method of applying a thin layer of hot molten plastic onto substrates such as paper, aluminium foil, corrugated fiberboard, cellulose, non-woven fabrics or plastic film.extrusion coating machine The coated substance then passes between a set of counter rotating rolls that press the coating and substrate together to ensure complete contact and adhesion. This process is called lamination or converting and can be used to produce a wide variety of products including food packaging, construction materials and flexible packaging for beverages and cosmetics.
The authors of this comprehensive book have combined experimental data with computer modelling to provide a unique approach to learning and understanding this important technology.extrusion coating machine The PC software used enables the simulation of the non-Newtonian flows of polymer melts in various parts of the processing equipment. This includes the screw and die areas, air gaps and chill roll cooling efficiency. The ability of the melt to bond with the substrate is also analyzed using this method. Melt velocity, draw rates and shear stress distributions in feedblock and dual manifold dies are simulated as well as cooling patterns in the air gap and on chill rolls. The influence of varying polymer feedstocks, pigment masterbatches and film types on interlayer instabilities is assessed and critical issues for coextrusion die design discussed.
An essential tool for designers and engineers of extrusion coating and laminating lines, the text is enhanced by an extensive range of colour illustrations to highlight key points of the process and to illustrate techniques of particular interest.extrusion coating machine It is also suitable for use as a textbook for courses on extrusion coating and laminating technology.
The book covers the fundamentals of extrusion coating and laminating technology as well as the more advanced topics such as multi-layer forming, co-extrusion, die cutting, blending, heat sealing and organoleptic characteristics of finished products. It also discusses in detail the opportunities to exploit a wide range of different polymers, copolymers and blends including LDPE, HDPE, PP, ionomers and EVOH.
A single extrusion coating line can be capable of producing a wide variety of laminated products ranging from snacks to retort food packages, and from paper packs for milk and liquor to medical packaging materials. The lines can be configured with a single, tandem or co-extrusion system. All systems are fully customizable to suit a wide range of applications with different production requirements. Typical end users include food packaging producers, manufacturers of breathable films and laminates, and the construction industry. SML’s extrusion lines are designed to meet these requirements with high quality production at a very competitive price. Our innovative and cost-efficient solutions are based on a modular concept that allows you to tailor the line to your specific needs. This flexibility is proven in many customer applications worldwide. Contact us for more information about our flexible and user-friendly equipment. We can even supply custom-engineered lines for your individual applications. This can be done quickly based on our modular design concept and our experience in extrusion technology.
