Types of Stretch Films That Are Meant to Be Used by Stretch Wrap Machines
Machine Stretch Films Are Stretch Films That Are Created Specifically To Be Used By Stretch Wrap Machine. Machine Stretch Films Have An Upper Hand When Compared To Non-Machine, Hand Stretch Films As It Provides Greater And Quicker Efficiency In Packaging, Greater Safety, Superior Load Containment, And Lower Material Spend. There Are Many Types Of Machine Stretch Films: Blown Machine Films, Cast Stretch Films, And Pre-Stretched Films.
Blown Machine Stretch Films
This Type Of Stretch Film Is Made Through A Process Known As Blown Extrusion. It Is An Operation That Includes Melt Plastic Being Pushed Inside A Circular And Slit Die That Further Results In A Rather Refined Tube. Next, It Involves Air Being Pushed In That Tube, Thus Granting A Volume Of Air That Is Enclosed So As To Expand The Tube To An Optimal Width. That Tube Is Then Topped With Air Rings That Is Further Blown Onto Substrate To Allow It To Chill. This Process Of Letting The Material To Cool Down Provides The Film That Is Blown With More Flexibility And Greater Strength Compared To Other Wraps. This Type Of Ensures That The Package Remains Secured And Is Therefore Recommended By The Pouch Packing Machine Manufacturer. Since It Is Stronger Than Most Of The Other Stretch Films, It Boasts A Better Resistance To Tearing As Well.
Cast Stretch Film
It Is Made Through Application Of A Comprehensive Manufacturing Process Known As Cast Extrusion. This Process Mandates A Continual Thrusting Of The Thermoplastic Substrate Inside A Flat Die And Then Onto Cooled-Down Roll. Film Gauge Is Then Resolved By The Degree Of How Quickly Casting Roll Will Drag The Plastic Away From Die. And This Process Causes The Cast Films To Provide A Superior Clarity, Thus Allowing The Users To Clearly Observe The Wrapped Products. Cast Stretch Films Stretches Easily Too Pertaining To Its Molecules Being Aligned Since They Are Extruded. Powder Packing Machine Uses This Kind Of Stretch Film Commonly. It Doesn’t Much Noise When It Is Removed From Rolls And It Is Simple To Stretch As Well, And Therefore It Is Commonly Used To Wrap Products Packaged Using Horizontal Form Fill Seal Machine.
Pre-stretch film
The Pre-Stretched Films Are Expanded Closer To Its Breaking Point Just Before It Is Finally Wrapped Onto Rolls. It Is The Type Of Stretch Film That Doesn’t Necessitate The Amount Of Energy That Other Types Of Stretch Films May Require To Achieve Similar Level Of Wrapping Force. When It Comes To This Type Of Stretch Film, The Consumption Is Often 50 Percent Lower As Compared To Other Types Of Machine Stretch Films, Thus Making It Cost Efficient.
Hay baling stretch film
It Is Stretch Film That Is Specialty, Multi-Layer, Stretch Wrapping Substrate That Is Made To Be Used For Wrapping Baled Hay-Rolls. Hay Baling Stretch Films Are Used Generally In The Farming And The Agricultural Industries. It Is Also Commonly Called Silage Stretch Wrap. A Lot Of Types Of Hay Baling Stretch Films Feature Ldpe (Or Low-Density Polyethylene) Formulations Along With Oxygen Barriers In Order To Keep The Hay Bales Dry.
