Two unusual concentrates for film & packaging.

Two specialized types of additive masterbatches for packaging were recently introduced by Ampacet Corp., Tarrytown, N.Y. One is a desiccant additive for LDPE and LLDPE film to help protect the contents of the package from moisture penetration. Ampacet Product 101499 is aimed at food and pharmaceutical applications, where it reportedly can extend shell life and/or permit cost savings through downgauging. The additive does confer some haze to the film.

The second unusual new product is a family of molecular tracers for flexible and rigid packaging that add distinct chemical "signatures" to plastic products. These tracers can be used to prevent counterfeiting, detect theft, and provide traceability for inventory and quality record keeping. New AmpaTrace technology can be applied to injection and blow molding, extrusion, and other processing methods. A variety of substances can be incorporated at parts-per-million levels and then traced by chemical analysis or radio-frequency detection. Different types, amounts, and proportions of tracers can be combined to create unique "fingerprints" for products. They can be included in additive masterbatches or supplied as their own masterbatch.
