25um strength blown film is ideal for privacy and high puncture resistancy. It is the industry game changer of black blown hand stretch films being the perfect solution for those that prefer a tough and tacky blown film to securely wrap their pallets while reducing film usage by at least 40%. The molecule structure of blown stretch film is criss-crossed which means when tensioned, it locks in very hard so therefore has a lower stretch yield compared to cast stretch films. 400 meter long roll. 500mm wide will suit all semi and automatic film wrapping machines.
