More and more manufacturers all around the world produced stretchwrap for products security purposes. Stretch film processors arebeing used in markets and every five years these have been doubled.The demands of stretch films developed in the mid of 1985 to 1990with 250 million lb/yr up to 500 million lbs. In the followingyears after 1990, the orders puffed up to one billion lb until theend of 1995. During these years, the five-layer film was the mostpopular even in recent times, but the demands still continued togrow in binary digits. For the past two years, the demand forstretch film resin has cut out to 1.4 billion lb. Stretch wrapreached 65% to 70% cast film and most of these are for machinepackaging, and for blown film it has 30% to 35% generally forproduct hand wrap and a little extremely pierce-resistant specialtyfilms.In the mid '90s when five-layer stretch wrap were launched, thehexane or octane LLDPE with one and three-layer films became areplacement. This requires a five-layer feed-block and fourthextruder with the use of low-cost butane LLDPE that supported withthin layers of metallocene LLDPE. A regular five-layer compositionis A-B-C-B-A having 10% hexane LLDPE exterior skins, 20%metallocene LLDPE as subsurface layers, and 40% butane LLDPEinterior. This means that mLLDPE has a little content percentageand somehow this makes the stretch wrap fragile and substandard.The demands have started depending on the variety of stretch wrap.Other manufacturers do not use mLLDPE as the main component of thefilms because they believe it is pricey. This perception of somemanufacturers is actually the reason why the demands for stretchfilms have been stalled down for the past years. Others have beenusing different chemical-based components that are less expensivein the production of stretch films. It is then found out that mostfilms made of these kinds can be easily broken because these arenot as durable as the mLLDPE. Consumers always look for somethingthat is of best quality and manufacturers should be aware for thisin order to meet the high demands of the consumers.Metallocene LLDPE resins are well-known for their exceptional flitimpact and pierce resistance, better organoleptics, excellent heatseal advantages, brilliant lucidity and superior warm tack. Thesecharacteristics of mLLDPE stretch films are preferably apt forhigh-performance film applications like for medical wrapping, foodsand goods packaging, and other applications. Metallocene LLDPE wasalso examined to have extensively enhanced sealing properties thanother polymers, thus improve the packaging line pace.Since the demands for stretch wrap continue to grow in as early asfive years, manufacturers produce these products in a constantbasis. Most of the manufacturers today fabricate mLLDPE stretchfilm not just to satisfy the consumers and meet their demands, butto give these consumers the privilege of using these products todifferent applications and purposes, and test how strong andeffective these metallocene stretch films are in securing theirgoods.
