Unraveling Polymers
BOPP Bags: The Modern Packaging Solution We have earlier looked at Turcite B * and Rulon and explained how they are the result of branding exercises that were set in place at a time when the polymer space was more obscure. In both their cases, we find that even today, older drawings received from OEMs will specify the brand and grade to be used and it usually takes some convincing and possibly development and trials on the part of the OEM to shift to an alternative. Both Turcite and Rulon, as we illustrated in earlier articles, are PTFE based materials. In some cases, specific pigments have been added to the material to enhance wear properties and offer a visual uniqueness to the grade that other processors might struggle to match. It should be mentioned that especially in the case of Turcite, the distinct turquoise pigment used brings certain synergies with the base PTFE material, causing the wear properties to increase significantly in comparison with other pigments.
