For several years, Braskem and SML have worked together on different topics in high quality stretch film. This collaboration has proved to be highly successful. Using post-consumer recycling material in stretch film represents an important contribution to the circular economy since it saves on resources and minimizes waste. We joined arms in our quest to produce market-conform stretch films containing at least the PCR content demanded by brand owners and stipulated in legal regulations. "At first it seemed nigh on impossible to find a sustainable and economical solution, especially when it comes to downgauged products. Finally, after 2 years of very close collaboration, development work, and countless trials together with Braskem, we are now in a position to offer the market a solution to the PCR demand in stretch film production which is certain to delight end users", Mr. Thomas Rauscher, Product Manager Stretch Film at SML, states. A satisfying answer on both the raw material side as well as the manufacturing side.

HIGH-QUALITY PCR: MILESTONE FOR THE MANUFACTURING OF PLASTIC PRODUCTS

What may seem unspectacular at first glance is a real milestone for sustainability in the manufacturing of plastic products. The reason for this is that it is a great challenge for companies such as Braskem and SML to present the stretch film solution with 30% PCR without compromising product quality or performance.

Stretch film used for the unitization of loads and protection in transport must be able to withstand great stress and need to be very resistant. For example, films produced with recycled material on the SML machine can achieve high performance in stretching and mechanical properties. The Wenew DL085C resin made it possible to bring to the market the film transparency suitable for this segment, as well as to meet the requirements of mechanical strength and elongation for automatic application in the beverage industry.

"The stretch film developed together with SML shows how far Braskem has already increased PCR quality and what is already feasible today. Combining Wenew products with Braskem's portfolio, we can achieve a film with extremely high-quality and thus helping to open completely new perspectives for the use of recycled materials in a wide range of applications," says Carlos André Silva, Subject Matter Expert at Braskem.
