Multiple layers co-extrusion blown film extruder referred to as the tubular multiple layers blown film extrusion, particularly for the products packaging industry. After solidification at the frost line, the film relocates right into a collection of nip rollers which break down the bubble and also squash it right into 2 standard film levels. The film passes with idler rolls throughout this procedure to make certain that there is consistent press in the film. Throughout this phase, the film could be slit to develop 1 or 2 films, or surface area corona finished.
The tubular multiple layers blown film co-extrusion that is the higher efficiency method of blown film extrusion process of extruding two or more materials simultaneously through a single die unit.
The tubular type multiple layers blown film co-extrusion is the least expensive means of producing layered films and saves time because it extrudes two or more layers at the same time that provides a method with fewer steps to produce multilayer films. The output for a coextruded multilayer film of 3 layers is approximately 130m/min, and also the output for a single layer of blown film is 65m/min. The film manufacture from the single layer procedure would certainly need an additional step to adhesive the layers with each other utilizing some kind of adhesive material.
Multiple layers co- extrusion blown film extruder features
Multiple layers co-extrusion blown film extruder is one of our featured machinery according to the demand of markets. Adopt the method continuously of squeezing horizontally and blowing upward, film folding width reach up to 800/1500 mm with thickness of 0.08 mm, suitable for LDPE, HDPE, LLDPE, MLLDPE, PA packaging film. Since its good barrier property, moisture preservation, moisture proof, rain water proof, wind proof, frost proof, oxygen insulation, oil resistant etc, thus can be widely used in packaging material.
Multiple layers blown film extrusion dies are accuracy made and also therefore are pricey however their life span is considerable. Each die head will have a working range of die inserts at different diameters to fit the needed application. Different die gaps can also be specified relying on the material being extruded.
The tubular type multiple layers blown film extruder's barrel and screw rods are all made of quality alloy steel that have been nitrided finished and processed by precision machining equipment. Hence it is sound in hardness, durable in corrosion resistance. The specially-designed screw is of sound quality In plasticizing, which helps increase the production capacity.

Properties of the tubular type multiple layers blown film extruder, such as tensile strength, flexural strength, toughness, and optical properties, drastically change depending on the orientation of the molecules. As the transverse or hoop direction properties increase, the machine or longitudinal direction properties decrease. For instance, if all the molecules were aligned in the machine direction, it would be easy to tear the film in that direction, and very difficult in the transverse direction.
In the cooling step of multi-layers blown film extrusion, the amorphous, transparent melt crystallizes to form a translucent, hazy, or opaque film. The point where opacity begins in the bubble is known as the frost line. And the frost line height is controlled by several parameters: the air flow, film speed, and temperature difference between the film and the surroundings.
Multiple layers co- extrusion blown film extruder application
Multiple layers co- extrusion blown film extruder can be used for the manufacture of co-extruded, multi-layer films for high barrier applications such as express delivery or fast mail packaging that are applied to the demands of shopping in internet.
Multiple layers blown film can be used for the manufacture of co-extruded, multi-layer films for inflatable buffer air column packaging bags with PA layer.
Multiple layers blown film can be used either in tube form plastic bags and sacks or the tube can be slit to form a sheet or film.
Blown film extrusion is used for extruding and blowing polymer film, raw material is HDPE, LDPE, LLDPE and PA etc, referred as to low density polyethylene (LDPE), high density polyethylene(HDPE)and linear low density polyethylene(LLDPE) etc, widely used for printing, agricultural and packing industrial etc. Blown extrusion film applications listed as below:
1. Blown film can be used either in tube form (e.g. for plastic bags and sacks) or the tube can be slit to form a sheet. Blown film extrusion can be used for the manufacture of co-extruded, double-layer or multi-layer films for high barrier applications such as food packaging.
2. Industry packaging (e.g. shrinkable film, stretch film, bag film or container liners).
3. Agricultural film (e.g. greenhouse film, crop forcing film, silage film, silage stretch film).
4.Consumer packaging (e.g. packaging film for frozen products, shrinkable film for transport packaging, food wrap film, packaging bags, or form, fill and seal packaging film).
5. Barrier film (e.g. film made of raw materials such as polyamides and EVOH acting as an aroma or oxygen barrier used for packaging food, e. g. cold meats and cheese), films for the packaging of medical products.
6.Laminating film (e.g. laminating of aluminum or paper used for packaging for example milk or coffee).
