Chyi Yang showed one set 3-Layer Co-Extrusion Blown Film Machine in 2014 Taipeiplas exhibition. We cooperated with Italy SYCRO to produce main parts including IBC, 3-layer co-extrusion die, air ring, automatic width & thickness controller. The internal bubble control (IBC) is available for film cooling & increasing output. Film width is set up by touch screen instead of manual operation. According to the oil price increases & not stable, Chyi Yang uses Automatic Thickness & Width Control to control the difference range between ±5% to save resin cost. The air ring is up-and-down moveable in order to improve the cooling when you run high speed. There are 48 points in air ring to adjust the thickness automatically. The extruders are 65mm & 90mm & 65mm, equipped with motor 75HP & 100HP & 75HP. The max. film width is 1500mm & the capacity is max. 8.4tons per day.

Except the above, this machine is also equipped with 360° oscillating nip roller device & tension controller & fully automatic winder. It is suitable for the production of laminating film, greenhouse sheet, construction sheet, food packages and sacks, etc. Material composition can be 2-layer of A+B structure, 3-layer of A+B+C or A+B+A. The screw material is bi-mental MAC-24 from Japan, the mixing design is very good for different resin composition, carbonate additive & recycled material. The 360° oscillating nip roller device can efficiently produce more uniform and flat film. The oscillating nip roll system mainly conquers troublesome rotary die maintenance problems which have been happening for several decades. In addition, it also provides the most efficient way to randomize gauge variations which are caused by ambient drafts. It results in the most smooth and perfect production rolls.
