We do that with our machines, of course, but we&#8217;ve also picked up some knowledge from our years of experience and more than 70,000 successful application installations. Based on observations of loading dock operations, and examination of many loads &#8211; both those that arrived intact and those that failed &#8211; we\u2019ve developed criteria to define an effectively wrapped pallet load. A safe-to-ship load must be:<\/p>\n<ul class=\"square-bullets\">\n<li>Wrapped with enough\u00a0<a href=\"\/r3\/blog\/check-your-containment-force\" target=\"_blank\" rel=\"noopener noreferrer\">containment force<\/a>\u00a0everywhere on the load<\/li>\n<li>Locked to the pallet with a film cable<\/li>\n<li>Have no long or dragging film tails<\/li>\n<\/ul>\n<p>You\u2019ll find a wealth of resources on our site around each of those topics, and our\u00a0<a href=\"https:\/\/www.lantech.com\/r3\/webinar-whats-best-way-to-stretch-wrap-a-pallet-load\/\">free on-demand webinar<\/a>\u00a0provides detailed guidance in a great 25 minute package.<\/p>\n<h3>Containment Force<\/h3>\n<p>Containment force is the key to effective stretch wrapping. It\u2019s the primary metric and the single best indicator of whether a pallet load is safe-to-ship. Containment force is the pressure applied to the load by the stretch film. It is what holds the load together. Contianment foce is the product of the film tension and the number of film layers.<\/p>\n<p>The right containment force depends on the product and type of load. For instance, paper towels in neat column stacks require very different containment force than order picked loads that are heavy and unstable.<\/p>\n<p>Containment force can be optimized, measured, and managed. And it should be. That means periodic checks and adjustments as film types and gauge change. It is also important to record this data.<\/p>\n<h3>Locking the Load to the Pallet<\/h3>\n<p>Loads sliding off their pallet is a frequent cause of product damage, but there is something you can do to help prevent it.<\/p>\n<p>Wrapping down to the bottom of the pallet, or simply bunching up some film for a \u201crope\u201d of sorts is not enough.<\/p>\n<p>We recommend rolling the film into a tight cable (so it doesn&#8217;t unravel like ropes can) and placing that cable about an inch below the pallet&#8217;s deck boards. The placement of the cable is importnat because it can be avoided by the forks of a pallet jack or forklift. When film is wrapped to the bottom of a pallet, it is punctured by forks when handled. This puncture can tear up the side of the load, resulting in reduced containment force and possible load failure.<\/p>\n<h3>Film Tails<\/h3>\n<p>Loose film tails drag behind loads. This creates safety risks, can cause loads to partially unwrap, or can result in loads \u201changing up\u201d on downstream conveyors or in automatic storage and retrieval systems.<\/p>\n<p>Tails must be managed. In many cases that means properly wiped down &#8211; relying on the cling in the film to keep the tail secured. In certain applications, like semi-automatic wrappers, it means managing the length and location of the tail. And for other automatic applications, it may mean heat sealing the tail.<\/p>\n<h3>Speed, Tasks and Cost<\/h3>\n<p>Your load and environment are important considerations and we\u2019re always happy to wrap sample loads or even look at pictures with you while talking through your requirements on the phone.<\/p>\n<p>Beyond the principles of wrapping, though, is a wide range of considerations that determine how to best wrap in your facility.<\/p>\n<p>Check out our section on \u201c<a href=\"https:\/\/www.lantech.com\/r3\/zh-hans\/how-to-buy-a-stretch-wrapper\/\" target=\"_blank\" rel=\"noopener noreferrer\">How to Buy a Wrapper<\/a>\u201d for more on cost considerations, machine options, speed ranges, and even solutions to free your warehouse team up to focus on the tasks they do best.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>At Lantech we\u2019re committed to making effective stretch  [&hellip;]<\/p>\n","protected":false},"author":11,"featured_media":67475,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"content-type":"","inline_featured_image":false,"_genesis_hide_title":false,"_genesis_hide_breadcrumbs":false,"_genesis_hide_singular_image":false,"_genesis_hide_footer_widgets":false,"_genesis_custom_body_class":"thank-you-page-2-col high-speed-stretch-wrap","_genesis_custom_post_class":"","_genesis_layout":"full-width-content"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v20.11 -
