Fluorescent Lighting

Potato chips packaged in oriented polypropylene/low-density polyethylene/polyvinylidine chloride, high-density polyethylene/ethylene vinyl acetate plus a UV-light-absorbing compound, or high-density polyethylene/ethylene vinyl acetate plus a titanium dioxide light-barrier constructions developed distinct oxidized flavors within 7 d when stored at 21°C, 55% relative humidity, and under 140–230 ft candles of continuous fluorescent lighting. Potato chips stored under the same conditions that were packaged in a high-density polyethylene plus titanium dioxide and a brown light-absorbing pigment construction or an aluminum foil/polyethylene construction were stable throughout 10 weeks of storage. Oxygen-barrier film characteristics did not influence the oxidative stability of the air-packaged potato chips.

Catalyst Production

The study observes the use of a waste derived from high density polyethylene (HDPE) catalyst production as fillers in papermaking. The replacement of the industrial waste to two common fillers; calcium carbonate and clay, are of interest. The waste is in the form of bright slurry containing very fine particulates with titanium dioxide, calcium oxide and alumina, along with a small amount of chlorides. As-received HDPE waste of 0-30 wt% was added into a mixture of pulp stock to make handsheets. Cationic polyacrylamide was employed as a retention aid. The obtained handsheet samples were then dried and their properties were characterized and also compared with the handsheets holding carbonate and clay. Such properties included both physical and mechanical ones, i.e. apparent density, air resistance, brightness, opacity, smoothness, tear and tensile strength. The experimental results showed that the as-received industrial waste gave comparable outcomes to carbonate and kaolin clay. Improvement of the handsheet properties with the HDPE catalyst waste was discussed.
