BS 7344:1990

What is BS 7344 – reeled LDPE film specification about?   

LDPE films have dynamic applications for packaging across industries. 

BS 7344 is a British Standard that specifies unprinted low density (k 927 kg/m3) polyethylene film in the form of sheet or layflat tubing, excluding coextrusions, in the thickness range 25 Èm to 300 Èm, available in widths up to 2 m (i.e. up to 4 m centre folded).  

BS 7344 includes tolerances on the length, width, weight and thickness of the film, and a classification system covering certain basic physical characteristics.  

Note: BS 7344 excludes special films.
