High Speed Extrusion Lamination Compound Machine
High Speed Extrusion Lamination Compound Machine
The High speed extrusion lamination compound machine combines multiple processes in one single system to achieve maximum production speeds and improved efficiency. It is capable of producing multi-layer, composite structures for a wide range of applications in flexible material converting. The line is easily upgraded to a tandem configuration to increase product range and enable faster time to market. The machine is also highly customizable, ensuring maximum accessibility and functionality for operators.
The high speed extrusion lamination compound machine can be used to coat and laminate a variety of substrates including paper, foil, plastic film, woven, non-woven and glass fibre fabrics as well as any material scrim or metal foil. It can be used to make a wide range of products including food packaging, fast food boxes, beverage bags, baby diapers, cement bags and roof radiant barrier products. The machine can also be used to increase water vapor and moisture barrier properties of a laminated product.
In addition, the machine can be used to improve the surface finish of a finished product, making it smoother and easier to print on. This is especially beneficial when printing on a thin plastic sheet, such as PET or PVC, where the substrate is often textured. This can be difficult to achieve with conventional lamination methods, which typically require the use of a hotmelt adhesive.
High-speed extrusion lamination compounds have the advantage of being more stable than traditional blown films, even at higher temperatures. They also have the ability to withstand greater heat loads than other types of laminations, such as hotmelt adhesives, which can melt or deform the plastic substrate. This type of film is ideal for demanding applications where the converting process requires exceptional stability, such as when manufacturing products for medical and pharmaceutical applications or food packaging.
When used for a specific application, it is important to choose the correct LDPE resin to maximize performance. For example, LDPE can be blended with tougher, metallocene catalyst resins such as m-VLDPE or m-ULDPE to make a stronger seal for laminates. It is also important to run the LDPE with a low melt temperature to reduce the possibility of crazing during the lamination process.
In order to reduce crazing, it is necessary to change the formulation of the plastisol ink or change the lamination conditions to prevent the formation of bubbles. To do so, it is necessary to increase the melt pressure or lower the temperature of the plastisol ink, which may be achieved by changing the extruder barrels’ temperature controls.
The present invention provides a solution to the problem of lamination by using an imine anchor coating agent in a solvent-based printing ink composition for extrusion lamination. The ink composition comprises a pigment, a binder resin, a chelate crosslinking agent and an organic solvent. The chelate crosslinking agent contains a titanium organic compound with a ligand having a hydroxyl group and a carbonyl group. In particular, the chelate crosslinking agent is comprised of tetraisopropoxytitanium and 2-ethylhexanoic acid or zirconium propionate.
