PE stretch film and packaging materials. From hand wrapping to machine applications, discover a flexible, clear layer for your packaging needs.

Made primarily from linear low-density polyethylene (LLDPE) using advanced cast film technology, this film is a core material in modern packaging.

For manual wrapping around packaged goods, offering a flexible format for everyday, smaller-scale packing tasks.

For use with stretch-wrapping equipment in repeated pallet packaging operations. Roll specifications must match the machine and application.
02 / PROCESS & EQUIPMENT
Explore how blending, extrusion, cast cooling and controlled winding turn resin into stretch film.
Explore the process
Polyethylene resin and additives are blended for the process.
Heat and a die turn the resin into a continuous melt.
Chilled rollers cool the melt into a film.
