The technical scheme that its technical matters that solves the utility model adopts is: a kind of sleeve type plastic film packaging bag, comprise the three-layer plastic film, and ground floor is made as bottom; The second layer is located on the ground floor, and along ground floor on one side and adjacent both sides, this limit inwards part cover ground floor, bonding the fixing of touching position at second layer edge and ground floor edge; Be located on the ground floor and the second layer for the 3rd layer, and along ground floor another side and this limit adjacent both sides inwards part cover ground floor, and be coated on the opening that the ground floor and the second layer surround, bonding the fixing of touching position at the 3rd layer of edge and ground floor edge, the touching position at the 3rd layer of edge and second layer edge is bonding or not bonding.

The area that the described second layer is covered in ground floor is less than half of ground floor area.

The area that the described second layer is covered in ground floor equals half of ground floor area.

The area that the described second layer is covered in ground floor is greater than half of ground floor area.

Bonding the fixing of touching position at described the 3rd layer of edge and second layer edge.

Described the 3rd layer of edge is with the touching position at second layer edge and freely contacts shape.

The touching position at described the 3rd layer of edge and second layer edge, bonding fixing on one side wherein, another side is and freely contacts shape.

The beneficial effects of the utility model are, owing to adopted the three-layer plastic film, two sacks have been constituted, and outer sack is coated on interior sack fully, and four limits of whole sack all are bonding shape, when need are put into bagging with article, drawing back outer sack can put into article by the 3rd layer and first, in the sack that the second layer constitutes, and then the interior sack that will be located in the aforementioned sack draws back, because plastic sheeting has certain flexibility, sack is easy to be drawn back, the part of article is entered in the sack that is made of the ground floor and the second layer, and article can not skidded off by four limits of sack like this, and sack is located at the centre, because article are to the anti-card effect of sack, article can not lost from sack yet; When need take out article in bag, just can easily article be taken out as long as draw back two sacks.This reality has the novel packaging bag of preserving specification sheets, laser disc, floppy disk that not only can be used as, and also can be used as the external packing of article such as books, but and repeated use, can play the better protect effect to article, as protection against the tide, insect protected etc.
