The film's elongation was good, and it was possible to use it without problems with our automatic packaging machine. (There may be some differences depending on the model.) When the wrap storage location is cold, the elongation of the lap decreases and it may rarely split. It can be avoided by using the wrap after accustoming it to room temperature. For automatic packaging machines, it is better to have a longer wrap length even for a little to reduce the labor of replacement work. It is saved when the variation increases to 750 m · 1000 m.
