Air is used to blow the bubble to size. Extruder screw, puller, and winder speeds are increased to provide the desired throughput rate and film gauge. Bruce 2024-12-1 021 Bruce 2024-12-1 08:58
Once the new film passes the top of the tower, the nip rolls are closed and the film continues through to the winder. Bruce 2024-12-1 017 Bruce 2024-12-1 08:57
As the extrudate is removed from the die, it is connected to the old film and pulled through the system at a slow rate. Bruce 2024-12-1 021 Bruce 2024-12-1 08:57
To string up the machine, the melt exiting the die is connected to a film that is strung through the film path and hung over the die. Bruce 2024-12-1 022 Bruce 2024-12-1 08:57
Compared to cast films, blown films are usually run at a lower melt temperature with lower melt flow index resins. Bruce 2024-12-1 020 Bruce 2024-12-1 08:57
Operating a blown film line is similar to other extrusion processes in that the polymer exiting the extruder must have uniform melt temperature and pressure while also being at the proper temperature and pressure. Bruce 2024-12-1 015 Bruce 2024-12-1 08:56
Films are typically defined as less than 0.254 mm (10 mils) in thickness, although blown film can be produced as high as 0.5 mm (20 mils) Bruce 2024-12-1 026 Bruce 2024-12-1 08:56
After it is expanded to the desired dimensions it is cooled to solidify the polymer. Bruce 2024-12-1 017 Bruce 2024-12-1 08:56
In this case the extrusion die is shaped as a circle and air pressure is used to further expand the film. Bruce 2024-12-1 021 Bruce 2024-12-1 08:55
Blown film is another extrusion processes used to fabricate film products. Bruce 2024-12-1 022 Bruce 2024-12-1 08:55
This unique composition of components offers a range of useful characteristics. Bruce 2024-12-1 015 Bruce 2024-12-1 08:55
BiONext is a combination of bioplastic and other components such as reinforced CaCO3 powder, modified starch powder, specific plasticizers, talc, and specific additives. Bruce 2024-12-1 013 Bruce 2024-12-1 08:55
In this regard, EuroPlas is a top masterbatch manufacturer in Vietnam, offering a wide range of bioproducts to meet the needs of various industries. Bruce 2024-12-1 017 Bruce 2024-12-1 08:54
For those looking to incorporate PBAT plastic into their products, finding a reliable supplier is crucial Bruce 2024-12-1 016 Bruce 2024-12-1 08:54
In this pursuit, PBAT (polybutylene adipate-co-terephthalate) plastic has emerged as a promising option. Bruce 2024-12-1 016 Bruce 2024-12-1 08:54
As environmental concerns grow, more and more companies are looking for eco-friendly and sustainable alternatives to traditional plastics. Bruce 2024-12-1 016 Bruce 2024-12-1 08:54
It is important to carefully evaluate the trade-offs between performance, cost, and environmental impact when making a decision. Bruce 2024-12-1 020 Bruce 2024-12-1 08:53
In conclusion, both PBAT vs PLA have their own unique advantages and disadvantages and the choice between them will depend on the specific requirements of the application. Bruce 2024-12-1 020 Bruce 2024-12-1 08:53
PBAT is more expensive to produce compared to traditional petroleum-based plastics, while PLA is typically more expensive compared to PBAT. Bruce 2024-12-1 019 Bruce 2024-12-1 08:53
Both PBAT and PLA are biodegradable and compostable, but PBAT has a faster degradation rate compared to PLA, meaning it will break down more quickly in the environment. Bruce 2024-12-1 017 Bruce 2024-12-1 08:53
