Cast stretch film - Offers Two Sided Cling that Allows the Wrap to Stay Securely Wrapped
Posted: Jun 13, 2017
Cast Stretch Wrap- Also called cast stretch wrap, is manufactured using a cast extrusion process. The Cast extrusion process is a continuous process by which a thermoplastic material is melted and extruded through a flat die onto a chill roll, where it is quenched and re-solidified. This process allows the Cast stretch film to have excellent clarity, require less force to stretch, increased tear resistance, unwind quietly from machines, and offer a superior cling. There are both machine grade and hand grade cast stretch film available.

Cast film production involves a different process. In this case the resin is extruded through a linear die and oozes out onto large diameter chilling rollers.Depending on the original thickness of extrusion, sometimes film is thinned to the target gauge by winding the resulting film faster than it is extruded.Cast film represents the other 70-80% of stretch film manufacturing according to general industry estimates.
Stretch films are highly engineered wrapping films which have been developed as a significant packaging solution across the globe. Stretch films are classified in two commonly used extrusion processes namely blown stretch films and cast stretch films. Blown film is tough and less stretchy whereas cast stretch film is easy to stretch and requires less amount of time as well as effort to unwrap the pallets. Manufacturers along with end-users usually prefer cast stretch packaging films as they are comparatively cost-efficient in nature. Cast stretch packaging film provides excellent clarity, superior cling and can be quietly unwind from machines. Cast stretch packaging films are produced from materials such as polyolefin polymers and are in great demand in food packaging industry.
Cast Stretch Packaging Films Market: Drivers & Restraints
Increased customer inclination towards safe, lightweight and cost-efficient packaging solution coupled with growing food and beverage (F&B) industry has emerged as the key driver of the growth in cast stretch packaging film market across the globe. Product shipping as a result of an increase imports-exports among the regions and also retail trade among suppliers and distributors also add to the growth of the cast stretch packaging films market. Also, as this films provide excellent clarity thus can allow the use of RFID and other scanning technology. However, As compared to blown stretch film, cast stretch films are less tear resistant thus providing less load power.
