inhibit dust adsorption, further improve the cleanliness; and the biaxially oriented film layer is used to make the inner layer 41, provide tensile properties, improve the deformation resistance in use, and provide protection for the function of the outer layer 42.

Drawings

Other features, objects and advantages of the present utility model will become more apparent upon reading of the detailed description of non-limiting embodiments, given with reference to the accompanying drawings in which:

FIG. 1 is a schematic diagram of the structure of the present utility model;

FIG. 2 is a schematic view of a bag layer structure according to the present utility model;

in the figure: the bag comprises a bag body-1, a bag opening-2, a lifting opening-3, a bag layer-4, an inner layer-41 and an outer layer-42.

Detailed Description

Referring to fig. 1 and 2, the present utility model provides an anti-contamination package bag: the bag comprises a bag body 1, wherein the bag body 1 is formed by a bag layer 4 in a heat sealing mode (as shown in the figure, an elongated bag layer 4 is used, folding is carried out at the middle section, and then the folding edge is subjected to heat sealing, so that a bag opening 2 is reserved);

the top end of the bag body 1 is provided with a bag opening 2, wherein the bag opening 2 is communicated with the inside of the bag body 1 and is provided for placing objects in the inside of the bag body 1;

the front end and the rear end of the bag body 1 are communicated with a lifting opening 3, and the lifting opening is close to the bag opening 2 and is used for lifting bags;

referring to fig. 1 and 2, the bag layer 4 includes an inner layer 41, two ends of the inner layer 41 are adhered and fixed with an outer layer 42, and two ends of the inner layer 41 are adhered and fixed with the outer layer 42 (which can be heat sealing or the like);

the inner layer 41 is a biaxially oriented film layer (may be a biaxially oriented nylon film layer or a biaxially oriented polyester film layer, etc.), and has good tensile effect;

the outer layer 42 is an antistatic polytetrafluoroethylene film layer, and according to the above, polytetrafluoroethylene can provide an anti-sticking effect, an antistatic function, and further improve cleanliness by inhibiting dust adsorption.

While the fundamental and principal features of the utility model and advantages of the utility model have been shown and described, it will be apparent to those skilled in the art that the utility model is not limited to the details of the foregoing exemplary embodiments, but may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
