CAPS & CLOSURES 25 PET planet Insider Vol. 19 No. 01+02/18 www.petpla.net pound grades are either GRAS (Gen- erally Recognised As Safe) or compli- ant with direct or indirect food contact according to the U.S. Food and Drug Administration’s 21 CFR regulations. They are also European Plastics Regulation-compliant (No 10/2011). Purging compounds improve efficiency Purging compounds can be an integral element in optimising output of injection moulded caps and clo- sures. Use of the right compound is not simply about cleaning; it becomes a key part of the preventive mainte- nance regime too. With proper regular use, purging compounds reduce carbon buildup from thermo-sensitive resins, working to preserve equipment and prevent wear caused by steel oxi- dation. This saves valuable time and cuts the incidence of ‘black specks’ during start up. Maintenance Chem-Trend offers injection moulders a range of products that ensure their caps and closures’ capacity remains optimum. Mould maintenance products like lubricants, anti-corrosion agents and cleaning materials all come with NSF registra- tion; they are completely safe for use in food and beverage packaging. Its range of cleaning agents easily remove resin, pigment deposits and contaminants from mould surfaces. High-performance lubricants resist the extreme pressures and loads intrinsic to the moulding pro- cess, remaining temperature- and viscosity-stable under typical thermo- plastic moulding parameters. They are designed to stay in place where they were applied, thus preventing through-vent migration. Even moulds in storage can be effectively protected against rust. Using anti-corrosion agents with NSF registration ensures that injection moulding machines create blemish- and defect-free parts from every shot. www.chemtrend.com INSPECTED BY COL LECT ING GU I DANCE TO PRODUC ING QUAL I TY DATA & TRENDS W W W .
