Plastics extrusion is a high volume manufacturing process in which raw plastic material is melted and formed into a continuous profile. One of the most common methods of film manufacture is Blown Film Extrusion. The process involves extrusion of a plastic through a circular die, followed by ‘bubble-like’ expansion. The principal advantage of manufacturing film by this process is stronger puncture resistance.
Our agricultural film is manufactured by five and seven multi-layer co-extrusion lines while single-layer and three-layer film production is increasingly intended for a limited and low target market.
The volume and pressure of air “blown” into the tube causes the material to stretch, thereby determining the overall size of the bubble and the width of the finished sheet.
This same action, in conjunction with the rate at which the bubble is being pulled upward away from the die, determines the thickness of the finished film.
The bubble begins the air-cooling process while traveling up to the nip rollers.
The multi-layer film ensures an enhanced management of raw process materials and optimized additive distribution in every layer, thus increasing film physical and mechanical properties.
With 5 layer technology, all the mechanical aspects of a bale wrap are maximised resulting in a consistently reliable, high quality, high performing film.
In order to provide the ideal ensiling environment balewrap needs to offer a number of important elements such as strength, puncture and tear resistance, elasticity, UV stability and the ability to cling in all circumstances.
Why Epic 5?
EPIC 5 made using blown extrusion which makes for stronger puncture resistance.
EPIC 5 is made by five multi-layer co-extrusion lines.
Multi-layering ensures management of raw materials and optimised additive distribution in every layer.
The Strongest and most technically advanced wrap on the market.
EPIC 7 is a 7 layer co-extruded blown stretch film developed with high performance advanced polymers, manufactured using the very latest state of the art 7 layer extrusion production systems.
EPIC 7 is produced in:
