If You Buy Fewer Than 10 Cases of Stretch Wrap at a Time, HERE'S HOW: Modern stretch wrap film is stronger and more puncture resistant. It also "necks down" (reduces in size when pulled) LESS. This saves you money and time. HERE'S WHY: Over the last 10 years, stretch wrap has vastly improved. Originally, all film was "blown film". Blown film is manufactured
by running molten resin over a die into which air is blown. The film is created by blowing up the film, not unlike a large balloon, and then running it through a series of rollers. Most modern film is "cast." That is,
the film is extruded and laid out in sheets. This allows the film to be made in layers. The layers allow strength to be increased by running the layers, much as plywood is stronger than a sheet of wood. Also, due to the layering
process, film can be made with "cling" on only one side. This is beneficial with light loads and any load in which items are backed close to one another. In the last 5-8 years, quality has increased further due to the
commercialization of linear low density polyethylene (LLDPE) metallocene resins. These resins can be designed to provide very high stretch percentages, excellent puncture resistance and high load holding force compared to standard
LLDPE. These new resin formulations also allow modern films to "neck down" less. Necking down is the reduction of the width of a film when it is pulled or stretched. This can make an 18" film more like a 15" film when
it is stretched. Modern cast film with metallocene resins necks down less. The bottom line is modern stretch wrap can replace traditional film with a thinner and smaller product. That means cost savings to you in film and less waste in our landfills. EVERYONE WINS
when using the right high quality film!!! |
