摘要：
A method of applying stretch film wrapping to an agricultural bale (10) whichis of rectangular cross section and using a bale wrapper apparatus which comprises:a table which supports the bale (10) and which operates to rotate the bale generallyabout its longitudinal axis (11) during a wrapping cycle； a dispenser reel arrangement(12, 13, 16, 17, 20, 21, 24, 25) from which stretch film wrapping is withdrawn soas to form successive overlapping windings of film which cover the bale； and meanswhich applies relative rotation between the table and the dispenser reel arrangementabout a second axis (14) which extends substantially perpendicular to said firstaxis during the wrapping cycle； in which: each winding of film includes a longitudinaledge strip portion and an adjoining longitudinal strip portion； and the longitudinaledge portion has different deformation properties from the deformation propertiesof said adjoining portion so as to be more readily extensible under a given loadthan said adjoining portion, and thereby to enable the winding to tighten itselfaround each corner (15) of the bale (10) and thereby at least minimise the generationof creases or wrinkles in the film winding at each corner region of the bale.
