It is used for blowing various plastic film of low density polyethylene (LDPE),high density polyethylene (HDPE)and linear low .

Three layer Coextruded(rotating Haul-off)Water-cool Blown Film Lines

Performance and Characteristics:

 It is used for blowing various plastic film of low density polyethylene (LDPE),high density polyethylene (HDPE)and linear low density polyethylene(LLDPE)etc., Which are Widely used for food, textiles, and daily necessities such as the packing industry and export packing and industrial packing.

The screw stem and cylinder are made of 38CRMOALA high quality alloy steel after fine finishing and nitrogen treatment, which has high hardness, strong resistance to corrosion, durable service.

The motor brand is Nanjing, gear box brand is 173 gear box from Xiaoshan Shuguang, hard-surface gear box, with auto oil pump, and water cooling.

There are two die heads, one air ring and two air ring mainframes on the machine.

The die head is plated with hard chromium and has screw mandrel structure with even and smooth material discharging. Up and down with converter, brand RiBo, which is from shanghai RiBo. Electric parts adopt Yatai. Air blower structure is maze model, even wind, heating ring is made by cast aluminum, automatic control temperature, automatic heating.

Elevator type to take up, and also u can according to different technics requirement to adjust the height.

The volume takes the installment to use the pressure fiction to receive the volume, up and down with cylinder, with air shaft, with adjustable speed motor to change speed, use the moment of force electrical machinery adjustment, receives the volume smoothly, to trade the volume to be convenient, and also with meter counter.

Feature:

Machine head use split-level spiral type, can 360 degree continuous rotation.Machine with some function equipment parts: remember length equipment, length cutting equipment, cooling water discharge, nip rolls, etc.three layers co-extrusion blown film machine is according to market to develop, and we absorb advanced level at home and abroad in machine structure. It can use flat method to produce film width 1000-1600mm constantly, and the thickness is 0.028-0.12mm all kinds of LDPE , HDPE, LLDPE, MLLDPE, PA etc. packing film. This type film has good barrier ability, moisture, damp proof, rain-proof, parsnip, frost protection, isolate oxygen, oil-proof, etc. so it is widely used on the packing, eg. Kinds of fruit, meat food, pickles, fresh milk, beverage, etc.
