Blown Film Technology Continues to Focus on Sustainability and Cost Savings
Sebastian Huennefeld, technical sales manager of extrusion systems at Windmoeller & Hoelscher, provides his well-honed insight on saving time and money in the blown film sector.
Q: Are there any developing trends/technologies you are noticing in the blown film sector?
A: The age-old trend is that companies are always looking for ways to save money and improve on sustainability. This has led to discussions, with almost all customers, about 5- vs. 3-layer films for their polyolefin-dedicated lines. Down gauging to thinner functional layers can save money by reducing the amount of expensive resins needed to produce an equally good or better structure, while still producing at maximum outputs.
