Preferably, it is thin in axial direction to form one layer of winding from the one ends wound of the support tube to the other end for the film The winding angle of film layer, upper layer and lower layer stretch wrap film layer film is different.

Preferably, one layer of stretch wrap film layer includes the film that spiral way winding is used by multi-turn.

Preferably, the film for no glue film or has glue film.

Preferably, the film is OPP material, CPP material, PE material, PET material or PP material.

Preferably, the support tube is plastic tube or paper tube.

As described above, this film has the advantages that the film uses on support tube around volume structure around volume structure The mode same layer coiling multi-turn film of spiral coiling, and the film edge superposition of two adjacent rings, can be effective using this structure The diameter for reducing entire film reel, reduces its space occupied, uses and store enhanced convenience；It is using this knot Structure, the edge superposition of adjacent turn film, can increase the support force of film, can for this not only thin, not only soft but also length film The problem of preventing " collapse volume ", make it is this it is not only thin, not only soft but also long film is more convenient is wound and uses；And it uses The case where inwardly collapsing will not occur in the edge of this coiling mode, entire volume film, and here can prevent film from crimping occur, turning over The problem of side, guarantees film normal use.Wind in this way the product of mode uncoiling using when to can obviously improve material every The axial movement amplitude of circle, axial wobble is releived without fierceness after making material uncoiling getting off from material volume, prevents film breaks, and The film material band distracted position taken off is easy to control, and tension is also more gentle to be stablized.
