The latest smarter news from RPC bpi group
beyond the headlines
RPC bpi indupac has a strong relationship with the petrochemical industry. The petrochemical industry supply the required raw materials to make film; while RPC bpi indupac supply the petrochemical industry with its PE products. The most important product supplied is our tubular film (“Politube”); this is used on Form Fill Seal (FFS) machines.
For many years RPC bpi indupac has been supplying the petrochemical market. In order to reduce costs throughout the value chain, the petrochemical industry will often focus on packaging. Down-gauging of packaging is a well-known and common project in the flexible film market. The goal is to make the film thinner without decreasing its stiffness or losing the mechanical properties of the original film.
As mentioned above, the main reason for a downgauging project is reduction in cost. However equally important is the smaller carbon footprint of the film – thinner films offer a more sustainable solution.
A good example of a downgauging project in the industrial petrochemical market are the bags used for 25kg polymers (PE, PP and others); this is an end-product used at all RPC production sites. The original thickness for this polyethylene-based film was 120 µm (10 years ago the average thickness was over 140 µm). Thanks to indupac’s recent down-gauging project this has now successfully been reduced to 100 µm. A more cost effective and sustainable solution which guarantees customers a perfect process at higher speed.
