Production Process

FILM BLOWING

In the film blowing process, we use advanced production equipment and imported raw materials to strictly control the protective film quality from the source.
PRINTING

In the printing process, we use environmentally friendly painting by introducing advanced production techniques and equipment, it is now possible to print four patterns and colors in one film.
COATING

We use imported glue and strictly control the quality of finished films, to achieve moderate viscosity and ensure no residue after the removal, also provide you with a good experience of use.
CUTTING

There are seven machines in our cutting workshop, each and every one of them can be adjusted to cut different lengths of protective films to meet your needs.
PACKAGING

We use standard seaworthy packaging to pack the films for you to avoid any possible damage during the transit and storage, packing of customization is also available for you.
Film Blowing

In the film blowing process, we always insist on using brand new and environmental-friendly LLDPE raw materials to ensure the stable quality from the very beginning and we absolutely say “No” to any recycled raw materials.
Film Casting

In the film casting process, our experienced team has every input data precisely set and checked to ensure the good and stable output of our final stretch wrap films. Because we always pay particular attention to every single detail during the whole proce
Film Testing

Our stretch wrap films feature strong toughness and tear resistance, and can not be penetrated easily by the nib under the intense stretch. They also feature strong tensile strength which enables you to wrap three more pallets with the same meters.
Packaging

We use standard seaworthy packaging to pack the stretch wrap films for you to avoid any possible damage during the transit and storage, you can also enjoy customized packaging from our side.
