Optimized extrusion coating die systems for flexible packaging

Flexible packaging is likely the largest market for extrusion coating and is certainly the most demanding. Production volumes are great, calling for coating systems that provide the highest levels of efficiency and raw material savings while entailing the least amount of downtime. The importance of ensuring the integrity of food packaging, the precision required for printing and sealing operations, and the complexity of certain coating structures—these call for stringent standards of quality and consistency.

The gel count standard in polymerisation and extrusion

Today value adding film producers and converting companies control their production inline 100% by using highly sophisticated optical camera inspection systems. These intelligent self-learning systems recognise the exact position of every defect, take a photo of the defect and warn the operator in time. This helps to control the extrusion and converting process better and to avoid the production of waste.

The benefits of web inspection are achieved in three parts of film extrusion and converting: the process itself, the raw material or the final product.

A review of coextrusion for flexible packaging

Modern, high-performance flexible packaging applications involve multi-layer films or coatings in order to match the desired performance and cost requirements for each specific application. Coextrusion is one of the most efficient methods to produce multi-layer films. In this presentation, we will review different coextrusion 
methods.

How to avoid angel hair?

Angel hair, also referred to as streamers, floss, and snakeskin, is created in pipes during high velocity pneumatic conveying. The higher the velocity, the greater the friction resulting in a high volume of fines and angel hair.

Extrusion coating and laminating - 101

Extrusion coating is the coating of a synthetic resin molten strip and extruding it through a flat die on a substrate. Combining two inexpensive materials to make a higher performance product adds value and utility. It is a flexible coating technique used for applying various economic plastics, including polyethylene, on cardboard , corrugated cardboard , paper, aluminum foil, cellulose, nonwoven fabrics, or plastic films.

Maximise blown film production output

Storing, conveying and distributing materials (especially additives) precisely and efficiently in a plastics processing plant can give significant cost savings. This is the case of Selene, a producer of thermoplastic film, which has recently implemented Winfactory, the innovative supervisory software of Piovan.

New 11 layer layout gives extra flexibility

The production of high barrier films with eleven instead of nine layers? On the one hand an investment in complex modern equipment and on the other an increase in flexibility. Nevertheless the question is: Is it worthwhile? The answer is a very definite yes! In less than a year the investment in an 11 layer blown film line instead of a 9-layer line can be amortised by fully exploiting the diverse opportunities offered by the gained flexibility, the possible savings in raw material and the augmented production capacity.
