Multilayer Blown Film line

Multilayer Blown Film line to produce variety of films like liquid packaging films, ultra high barrier films, meat and cereal packaging films, oil packaging films, pharmaceutical and medical grade films, green house films, geomembrane and chemical / soap packaging films etc.

Main programmable logic controller (PLC) features a large color touch screen control panel for access to line setup and operation.

The gravimetric system weights the resin before feeding it into the extruder. This unit communicates with the PLC ensuring accurate measurement of resin into the extruder maintaining consistent production.

The extruder heats the resin so that it becomes homogenous upon exiting the extruder. Custom and traditional extruder length to diameter ratios (L/D) are tailored to suit the resin in order to maximize output and efficiency. Up to 8" diameter screws can be designed for maximum throughput.

Die packages form the molten resin into a thin tubular film. Pancake and spiral die packages are designed with the aid of computer simulations ensuring even mixing and heat distribution of the molten resin. Up to 11 layer films can be constructed using these die packages.

Single and dual lip air rings with up to 110" diameter and fully automatic computer gauge control.

The bubble is pressed flat in the collapsing frame and pulled through two rollers which are referred to as the top nip. The flattened bubble is now referred to as the layflat. Touch button controls are able to open or close the position of the collapsing frame in an effort to avoid web wandering, eliminate the formation of wrinkles and maintain the quality of the layflat.

Modular design for easy assembly and solid structural construction

The bubble guide increases the stability of the blown film tube providing support to maintain its shape. It can be adjusted to move up or down and open or close its arms to provide support along the length of the tube. Contact surfaces can be selected according to the thickness and surface type (high slip or tacky) of the film.

The chiller unit provides a steady supply of cooled air that can be fed to the air ring and/or the IBC to solidify the film.
