in favour of pea recent development in vented polythene packaging for cement is the commissioning of yet another arodo twinspout pe packer at the hanson plant in padeswood, north wales next month.the recently installed line will reach output up to 500 bags per hour and adds further weight to the position that polythene will become the new normal in packaging for cement.this is reflected in the fact that numerous major global cement manufacturers are increasingly shifting the balance of packaging for cement in favour of vented polythene, with orders for specialist bagging equipment that can process vented polythene sacks increasing so dramatically in the last 12 months that equipment manufacturers are operating at near capacity.likewise, demand for ventisack, bpi.visqueen&rsquos own vented polythene sack, has doubled in the same period for alreadyinstalled lines. with polythene packaging, it is possible to print highimpact colours with 360° coverage. driving changeat the heart of this transformation is an appreciation of the numerous functional benefits of packing cement in vented polythene.one of the most common causes of product spoilage in traditional paper sacks is water ingress &ndash a question to which vented polythene appears to be the answer.vented polythene sacks create a protective waterproof barrier that keeps water out whilst enabling cement to breathe. trapped air is then vented out during the packing and palletisation process &ndash ensuring pallet stability. enhanced tear and puncture resistance also significantly improves shelf life of packaged cement.additionally, as paper sacks are typically porous, which allows dust particles to escape, packaging often appears visually unattractive and, due to subsequent seepage, can also create mess and waste throughout manufacture, storage, transport and retailing. as a nonporous material, vented polythene prevents messy seepage. as a result, vented polythene sacks also present a cleaner handling experience than paper sacks, meaning they are more retailer and enduser focused.ultimately, packing cement in vented polythene protects product from the elements, enhances shelflife and prevents messy seepage. however, the benefits of packing cement in polythene extend beyond the functional.premiumisation and innovationmore impressively, packing cement in vented polythene has also led to a dramatic shift in product perception, which has led to the premiumisation of cement packaged in polythene.in addition to the functional benefits that are apparent, end users also naturally anticipate a better user experience &ndash end users intrinsically understand the many benefits of cement packaged in vented polythene and are willing to pay a premium for it. this is reflected in the fact that cement packaged in polythene is typically priced several price points higher than traditional paper sacks &ndash even where they are sold side by side.the ability to print in a high impact eight colours with 360° coverage of the entire film tube also means that polythene offers an enhanced marketing vehicle in comparison to traditional paper sacks &ndash enabling cement manufacturers to present the benefits of their products like never before.this enhanced promotional potential enables brands to connect with their end users in an entirely new way that is not achievable with traditional paper sacks &ndash adding to and supporting the credibility of product benefits whilst instilling confidence that the product will meet their needs and expectations.in commercial terms, vented polythene packaging for cement appears to have reinvented a traditional product that may have otherwise struggled to challenge ingrained longstanding brand sentiment.environmentally soundin stark contrast to typical perceptions of plastic packaging, an independent study has shown that plastic cement packaging is more environmentally friendly than paper packaging during the full term of its use.it highlighted that the amount of cement wastage caused is the most significant aspect determining the environmental effect of paper bags and that one tenth of paper bags are damaged after receipt by the merchant.the same study also determined that plastic bags use less energy than paper bags, and a us environmental protection agency report showed that plastic bags typically use 40 less energy to produce and generate 80 less solid waste than paper. it also takes significantly less energy to recycle plastic than paper.the complete story of a product&rsquos environmental credentials is becoming a key factor in buying decisions &ndash not just where it comes from and how it was made, but also how it is packaged and the environmental impact this has.as vented polythene sacks are 39 more environmentally friendly than paper bags source lafarge, they are the packaging media of choice across a range of industries, including cement.investing for the bigger pictureresponding to this persistent shift towards vented polythene sacks for cement, bpi.visqueen has geared up to cope with even greater demand from the global cement industry. for example, the company has invested in a new polythene extrusion line alongside a dedicated printing and conversion facility to cope with the increasing demand for vented polythene sacks.meanwhile, it is becoming increasingly apparent that vented polythene is also an attractive packaging medium for other moisture sensitive goods that are stored outside or packed on highspeed packing lines.ultimately, bpi.visqueen is preparing to lead the way in vented polythene packaging as an alternative to traditional paper sacks.written by david khanna, commercial director, bpi.visqueen, uk. this article featured in the may 2015 issue of world
