Classification Dry Lamination Film Co-extrusion Film
Processing Method LLDPE(extruding) + NYLON Pressing.LLDPE / NYLON hardened after 1st, 2nd lamination.Cut out to each width. LLDPE + NYLON extruding.Cut out to each width.
Advantages Excellent protection performance against impact due to the high tensile strength of film.Long air Pressure remaining time due to low oxygen transmission rate. => Suitable for all terms of distribution. Low price.
Disadvantages High price. The usage is limited due to low film tensile strength of the film.Short air Pressure remaining time due to high oxygen transmission rate. (Not suitable for long-term distribution)

※Rival manufacturers are using unified film with low specification as co-extrusion film + co-extrusion film to enhance the sales margin.
For better quality INDIS Air selects high-quality films than combining low-cost films which can maximize manufacturing margins.
