The Extrusion Coating Lamination Compound Machine
The Extrusion Coating Lamination Compound Machine
The extrusion coating lamination compound machine is used to coat a variety of substrates, including paper, metal foil, nonwoven fabric, and plastic film.extrusion coating lamination compound machine It can also be used to protect printed substrates from moisture. The process works by melting a thermoplastic material in the form of a liquid or powder to create a layer that is then laminated to another material. Extrusion coating is a flexible and cost-effective solution for many applications. It can be combined with a wide range of materials to provide a customized product for your specific needs.
The key to successful extrusion coating is the balance between shear and tensile strength, viscosity, and surface characteristics. These factors are related to the type of resin used and its rheology, the level of polymerization, and the melt temperature of the extruder. Several different techniques can be used to adjust these properties and achieve the desired results.
For example, a "matte" finish can be achieved by using a high level of shear and low tensile strength to reduce shape change. A "mirror pocket" finish, on the other hand, uses a large number of randomly shaped pockets to increase slip and lift air, which improves the clarity of the coated substrate. These variations in surface properties are critical to ensuring that the finished product meets your specifications and produces a good seal.
Another important factor in determining how well an extrusion-coating system will perform is its ability to provide a strong seal. In some cases, a thinner adhesive layer is required to provide the necessary tensile strength for the structure. In other cases, a more substantial plastic component may be needed to provide an adequate amount of insulation. This is especially true when the product will be subjected to taste-sensitive conditions, such as high-end tea and coffee packaging.
In these situations, the choice of an adhesive or a thicker extrudate will have a significant impact on the overall performance of the finished product. For example, a softer blown film resin will not have the same tensile and shear strengths as a tougher m-VLDPE or m-ULDPE blend.
To prevent these problems, the manufacturer should choose a stronger blown film resin or run the extrusion-coating system at a lower shear speed. The manufacturer should also consider blending the m-VLDPE or m-ULDPE with a tougher, metallocene catalyst resin to increase the seal strength without reducing its shear resistance and shear index.
In addition to a variety of extrusion-coating systems, Worldly also manufactures an extensive line of co-extrusion equipment, including mixers, batch blenders, and chill rolls. The company's products are designed to meet the requirements of a broad range of applications, from high-end pet food packaging to industrial bags and sacks. The systems feature fully computer control, allowing the operator to adjust the production parameters easily and quickly. The co-extrusion machines can be customized to meet the specific needs of each application, resulting in high-quality, high-performance extrusions. They are also designed to produce an even coating and minimize waste.
