Although some converters avoid them due to concerns that they can increase back pressure and cause gels, they help fulfill a number of important functions that can unlock major performance improvements.\u003C/p\u003E\r\n\u003Cp style=\"line-height: 1.5; color: rgb(64,64,64); font-family: Arial , Roboto , Helvetica , sans-serif; font-size: 14.0px;\"\u003EShaun Pirtle comments, “A screen pack has many functions in an extrusion line. First, it acts as a filter and prevents large gels and contaminants such as sand, dirt, and metal from entering the die, where they might scratch and damage the finely polished surfaces and likely become stuck. Second, the screen pack also functions to help in mixing the polymer melt and reducing the ΔT across the melt flow, which helps in thickness control.”\u003C/p\u003E\r\n\u003Cp style=\"line-height: 1.5; color: rgb(64,64,64); font-family: Arial , Roboto , Helvetica , sans-serif; font-size: 14.0px;\"\u003EWhile screen packs provide multiple productivity-boosting benefits, operators should be aware that screen packs will build up back pressure slowly over time as contaminants collect on the screen. If the screen experiences an unexpected drop in back pressure (usually below the initial back pressure of the fresh screen pack), this is a sign that it has broken. Maintenance teams should immediately replace the screen pack, since it is no longer preventing the contaminants from getting into the die.\u003C/p\u003E\r\n\u003Ch2 style=\"font-family: type-font , Arial , Roboto , Helvetica , sans-serif; line-height: 1.5; color: rgb(64,64,64);\"\u003E2.

But, they are also prone to breaking if they experience unexpected drops in pressure. According to Adam Mix, he’s seen this issue fairly often, which prompts him to conduct root cause analyses to understand what is happening.\u003C/p\u003E\r\n\u003Cp style=\"line-height: 1.5; color: rgb(64,64,64); font-family: Arial , Roboto , Helvetica , sans-serif; font-size: 14.0px;\"\u003EHe elaborates, “Screen pack breaks occur when there is high back pressure and happens most often when starting up a cool extruder before the resin has reached a high enough temperature to flow easily. In essence, screen pack breaks usually occur because the operators are too eager to get back online and start up production quicker than is best practice.”\u003C/p\u003E\r\n\u003Cp style=\"line-height: 1.5; color: rgb(64,64,64); font-family: Arial , Roboto , Helvetica , sans-serif; font-size: 14.0px;\"\u003EHe also recommends looking at how the screen packs are installed. Screen packs need to be supported from the breaker plate (downstream) side of the screen pack. Symmetrical screen packs that are welded together often provide the best performance.\u003C/p\u003E\r\n\u003Cp style=\"line-height: 1.5; color: rgb(64,64,64); font-family: Arial , Roboto , Helvetica , sans-serif; font-size: 14.0px;\"\u003E\u003Ca href=\"https://www.shell.us/business/sectors/shell-polymers/resources-and-insights/leveraging-hdpe-film-for-consumer-packaging-applications.html\" target=\"_self\"\u003EDiscover the Advantages of Leveraging HDPE Film for Consumer Packaging Applications\u003C/a\u003E\u003C/p\u003E\r\n\u003Ch2 style=\"font-family: type-font , Arial , Roboto , Helvetica , sans-serif; line-height: 1.5; color: rgb(64,64,64);\"\u003E3.

When in reality, PPAs have the potential to unlock value in a variety of ways and have a major impact on an extrusion line’s product quality and output and, therefore, its profits.\u003C/p\u003E\r\n\u003Cp style=\"line-height: 1.5; color: rgb(64,64,64); font-family: Arial , Roboto , Helvetica , sans-serif; font-size: 14.0px;\"\u003E“PPAs bring a wide variety of benefits to an extrusion operation.” Dan Falla explains, “They can enhance product quality because they help prevent melt fracture, improving the film’s surface appearance. PPAs also enable narrow die gaps to be used, which result in films with increased physical strength.”\u003C/p\u003E\r\n\u003Cp style=\"line-height: 1.5; color: rgb(64,64,64); font-family: Arial , Roboto , Helvetica , sans-serif; font-size: 14.0px;\"\u003EIn addition to positively impacting product quality, PPAs also contribute to reduced die lip buildup, which means less time required for die cleaning, fewer surface imperfections, and less scrap. They can help increase output by reducing the back pressure and the motor-load drop, and increasing the extruder screw speed.\u003C/p\u003E\r\n\u003Ch2 style=\"font-family: type-font , Arial , Roboto , Helvetica , sans-serif; line-height: 1.5; color: rgb(64,64,64);\"\u003E4.
