Micro perforation - Import export

Warning foils Warning (cautionary) foils made from PE (polyethylene) using extrusion technology. They are produced in various colour designs, with single- or double-sided pattern, with micro-perforation or without perforation. They serve as an indication and warning of the existence of cable routes and other conducts embedded in ground excavations, etc. These foils do not provide mechanical protection of such networks. Processed materials LDPE LDPE is a polyethylene with lower density. It is the most frequently used material in the production of foils, in particular for packaging. All simple types of disposable bags, garbage bags, and shopping bags are made just from LDPE. The reason is particularly its low price and easy processing ability. Foils are manufactured by extrusion, either as 2D foils or hoses (tubular extrusion). Foils can be made as very thin (bags for baked goods) or thick-walled (large bags). Package thickness may be adapted to application requirements from 30...
