Further, the shape of heat seal end is selected from the shape that square or one section of camber line and two right-angle sides surround.The shape of the latter decreases three wedge angles, stressed more balanced, and when can avoid using, load-bearing causes sharp corner damaged.

Further, camber line is selected from circular arc, elliptic arc.

Further, camber line is the arc of circle or an oval quadrant.

Rosin collecting bag of the present invention, adopts the inflation film bag volume meeting dimensional requirement, by heat-sealing machine continuously heat seal be processed into the forms of many bags of arrangements, then disconnected also rolling rolling, finally tears apart and forms; Or directly cut after the form becoming many bags of arrangements and form.

The described dimensional requirement that meets refers to and Size calculation according to rosin collecting bag can make full use of raw material, avoids waste as far as possible.

Rosin collecting bag of the present invention is hung in the tree, and form three openings, the sack between top sack two heat seal ends is less, enter wooden slag in bag and pine needle few, and collecting bag one hangs up tree, and sack is just dark ensconces in the wall of ravine, whole collecting bag seems full, does not have parietal suture, does not have oil leakage phenomenon.

The present invention forms owing to adopting heat-sealing machine Continuous maching, and evenly, without little eye, good sealing effect, sack is oil-proof for extensions bonding.And hook place is firm.
