Multilayer blown film involves the co-extrusion of multiple layers of polymer resins to create a single, composite film. Each layer can have distinct properties, such as barrier characteristics, strength, or optical properties. This technology opens up a realm of possibilities, allowing manufacturers to tailor films for specific applications with precision.
Different layers can be composed of various polymers, each contributing specific attributes to the final film. This versatility allows for the creation of films with a combination of properties such as strength, flexibility, barrier performance, and heat resistance.
The development of barrier films has been driven by the expanding demands of the packaging industry. This has resulted in the adoption of both symmetrical and asymmetrical complicated structures, as well as the advent of EVOH and early, basic PA/PE structures.
Modern Cylindrical Spiral Die is installed on a 7-layer blown film line. Short polymer flow passageways minimize dwell time, which is very advantageous when working with heat-sensitive materials since it slows down polymer degradation and expedites material changeover.
Blown film lines with seven layers that are tailored to the type of film to be made. Advanced automation features such as automated thickness control (using a non-contact capacitive sensor), gravimetric mixing and dosing, extrusion control, non-contact type IBC system, and a fully automatic surface winder that can be tailored to various applications are available for 7-layer blown film lines. It is user-friendly since it has integrated touch screen-based supervisory process control.
The range of applications include films for long shelf life packaging of edible oils, UHT milk, liquid and solid container liners, frozen food packaging, meat packaging, vacuum packaging, barrier thermoformable film for trays, cups and lid etc.
The ROI is further enhanced by the all-PE 5 layer co-extruded blown film line’s downgauging, reduced final film cost, and versatility across applications, which are designed to fulfil unique demands.
This five-layer line guarantees a thin layer of property polymers on the outside and a thick layer of low-cost materials inside. It also gives processors enough flexibility to make films that meet demanding industry standards and meet specifications that give their customers a competitive advantage in terms of a variety of film properties and, of course, lower costs. When compared to a traditional 3-layer option, the film capabilities with a 5-layer are noteworthy.
Five-layer PODs have emerged as a rapid solution for attaining the required printability, sealability, and optical qualities by harmonizing the features of the novel resins hitting the raw materials market.
Gravimetric Dosing System, Extrusion Process Control, Air / Water Chiller, Corona Treater, Bi-Metalic Screw & Barrel Set, Hydraulic Unloading, Digital Web Aligner, Empty Shaft Loading system, Hydraulic Unloading System, Main Panel Air Condition, Auto Thickness/Width Control, S wrap Cooling System etc.
5 Layer POD lines are tailored for various application segments such as collation shrink films, lamination grade films, milk and water pouches, edible oils, courier bags, and many more.
To meet specific needs, an all-PE 5-layer co-extruded blown film line benefitted with down gauging, lower cost of final film, and adaptability across applications enhancing the ROI still further.
Three-layer non-IBC and IBC machines are only two of the many configurations available for the Innoflex Multilayer co-extrusion blown film lines, which may be used to create a wide range of films.
Our consumers receive value from us because we are passionate about innovation. By offering specialized machine configurations, we at Innoflex have completely changed the way our clients may obtain the consistent, high-quality film, improved production, and best-in-class flexibility.
The lines can produce a variety of materials, including PP, mLLDPE, LDPE, LLDPE, HDPE, SEALANT POLYMERS, ADDITIVES, and MASTERBATCHES. Because the machine combination enables the processor to operate layer ratios up to 1:3:1, it lowers the cost of the recipe. Modern Cylindrical Spiral Die is installed on a three-layer blown film line. Short polymer flow passageways speed up material changeover and reduce polymer degradation, all of which are very beneficial for processing heat-sensitive materials.
