As machinery technology developments allow for more and more layers to be coextruded, more and more properties and uses of blown film are being discovered. In Part 2 of this series, we'll cover the uses …
Blown Film. A process known as blow film extrusion uses an industrial blower to expand a hot plastic tube into a light, strong plastic bag. The air inflates the plastic tube like a balloon until a bag with the desired shape, size, and wall thickness is formed. The balloon moves slowly up a tower, the bubble being contained by rollers that fold ...
Every formulation and manufacturers is a bit different, but some general rules of thumb apply. Blown stretch film tends to: be very resistant to puncture. have higher levels of "cling" (how the film 'sticks' to itself) make more noise unwinding. Cast stretch films often: are clearer & shinier on a load. unwind quieter.
The biodegradable stone paper can be easily made using relatively cheaper blown film process. The stone paper can also be made from CaCO3 waste of traditional paper industry and recycled polymer ...
The blown Film Process is a continuous process, as such the machinery has to be designed to cope with both the high speeds involved and be able to operate on a 24 hour basis.
gloss film), and gloss-85 is ill-suited for providing resolution between samples. It also concludes that gloss-45 is a suitable choice for providing resolution between polyethylene blown films. Part 2 of this paper explores the contribution to gloss-45 through varying the layer arrangement and layer composition in coextruded blown films.
The invention relates to a stone paper film forming technology. A stone paper film forming device consists of an extruder and a film blowing device, wherein the extruder and the film blowing device are horizontally arranged in a straight shape, do not have high requirements on plants, are not limited by fields, are safe, have simple technology and low cost, and …
Blown vs. Cast - How is stretch film made? Jun 20, 2016· Blown film is created as the thick layer of extruded film emerges from a circular die and a large bubble of air is blown inside. The volume of the bubble, and the original diameter and thickness of the extruded tube determine the ultimate gauge (thickness) of the material.
Stone paper equipment consists of an extruder and film-blowing equipment that forms stone paper films, and they are symmetrically aligned horizontally in a straight line. The compressor, compressed air charge interface, air blower, air-cooled air ring, V-shaped gradually flattened and … See more

5.1 Introduction to Blown Film Extrusion. Blown film extrusion is the most important process for the production of plastic films, ranging in thickness from 0.5 mm to as thin as 5 μm according ...
Figure 4. A cross-section of a seven-layer, nested spiral, blown film die. Courtesy Gloucester Engineering. In some parts of the world, some resins are simply not available, so substitution becomes a necessity. Moving to nine layers gives further flexibility to the blown film manufacturer without sacing film properties.
Anti-blocking (silica) and anti-slipping agent (Ethylene bis-stearamide (EBS)) were added to improve the processability of the blends, specifically to solve winding issues of the blown film and unfolding of …
The sealing performance and seal integrity is superior to BOPP, also puncture resistance and a linear tear behavior for easy opening is beneficial. Brückner offers a BOPP / BOPE hybrid-line concept for a full output and high film quality situation at both products. Line width: 6.6 m and 8.7 m. Speeds up to 525 m/min. 5-layer configuration.
