Plastics Play a Pivotal Role in Paper & Paper Packaging Industries
Interstate Plastics is a leader in plastic solutions for the replacement of metals in manufacturing components used in packaging and paper mill machines exposed to corrosives, moisture, temperature and changing conditions.
In Kraft, duplex, newsprint and other manufacturing machines, Interstate Plastics offers replacement material solutions for OEM parts made from durable nylon, UHMW, acetal, Delrin and other low friction materials to increase dewatering efficiency while keeping the properties of the paper intact and consistent.
Plastics including UHMW and acetal do not rust like many metal counterparts and survive in the harshest of environmental conditions. OEM plastic replacements allow paper packaging manufacturing machines to operate effectively with a variety of paper types.
Our OEM replacement part solutions also play to plastics' advantage in "pulpers" - paper pulp machines that operate in wet conditions. Pulpers have recently seen an increase in the use of plastic components as new plastic technologies have pushed the previous limits of plastic load-bearing, torque handling, and gear drive capacities. Interstate Plastics OEM replacement part solutions can turn heavy pulp loads without deformation.
Many materials used in paper pulp applications leave small filings or chips that contaminate the paper its magnetically detectable polymer material which can easily be separated from wood pulp in solution. This is an especially important solution in premium and sensitive paper products like those used in glossy magazines. Tivar® PolySteel is highly utilized in chip sizing screens, flat back elbow liners, under chain wear plates, and wood chip drag conveyor flights.
This problem is not unique to plastics, but can be solved by using a "pulp safe" plastic grade (materials with a specific gravity greater than 1). Interstate Plastics provides Quadrant's Tivar® PolySteel due to its high specific gravity and UHMW, nylon and acetal components work well in other paper packaging applications include pressure screens, pulp agitators, formers, presses, dryers, reels, fluids, threaders and finishing systems. Examples include Paperchine® SigmaPro™, DeltaPlatform™ and VIB systems; AstenJohnson®, S.L. Paper Machines®, and Krystian® paper processing and pulp preparation systems.
OEM plastic applications work well in paper packaging conveyor systems where plastic wear parts enable extended part life. Plastic parts featuring low friction lead to damage free boxes, bags, rolls, and sensitive packaging materials. This will save money on reduced damaged runs and longer intervals between replacing parts.
Interstate Plastics plastics have been used in DGT Solutions® and Parker SSD Engineered Drives® side loading, drop load, and pick and place case packaging machines. UHMW, nylon and acetal components are also used in bundler strapping machines, seal systems, printers, label applicators, wrapping systems, as well as case, box, carton and tray erectors.
Interstate Plastics offers nylon and natural UHMW in FDA approved and USDA compliant grades.
