Abstract
The utility model discloses an easily-torn composite film which is mainly composed of a polyolefin resin heat seal layer and a rigid organic resin film with a plurality of protrusions on the surface. Since the multiple protrusions are formed on the surface of the rigid organic resin film, roughness of the surface of the rigid organic resin film is improved to enable the rigid organic resin film to be easier to tear as compared with rigid organic resin films without protrusions on the surfaces. Therefore, users can tear at any positions of the edge of a packaging bag with hands to open the packaging bag, and utilization requirements of the users are met.
Description
Technical field
The utility model relates to the composite membrane technology field, relates in particular to a kind ofly easily to tear composite membrane for the manufacture of packaging bag.
Background technology
The existing composite membrane that is composited by the rigidity organic resin film, owing to cannot free-handly tear and open, so the packaging bag that is formed by its manufacturing will increase specifically created breach or crack and reach the purpose of opening easily, such as the side precalculated position in packaging bag recess is set, or the precalculated position, lower end forms zigzag gauffer etc. thereon.But the defective that the packaging bag of this structure exists need to (being indentation, there or crack place) just can open the package in specific position exactly, says nothing of and can open the package in heat seal lands, uses very inconvenient.
The utility model content
Technical problem to be solved in the utility model provides a kind of suitable manufacturing packaging bag, and can free-handly tear in any position, packaging bag edge open easily tear composite membrane.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model content is specific as follows:
A kind of composite membrane that easily tears, it mainly is composited by vistanex hot sealing layer and the surperficial rigidity organic resin film that forms a plurality of projections.
Need to prove that the quantity of wherein said projection is at least and can makes the user can free-handly tear with of the present utility model easily tearing the quantity of the packaging bag that composite membrane makes or greater than this quantity.
Preferably, the composite membrane that easily tears of the present utility model also comprises the barrier layer of being located between described organic resin film and the vistanex hot sealing layer; Described organic resin film connects described barrier layer by an adhesive layer; Described vistanex hot sealing layer connects described barrier layer by another adhesive layer.
Preferably, described barrier layer is any in aluminium foil, aluminizer, applying silica film, plating di-aluminium trioxide film, coating polyvinylidene chloride film, ethylene-vinyl alcohol copolymer, the fluoropolymer polymer.
Preferably, described adhesive layer is any in polyester-urethane resin, polyethers-urethane resin, isocyanate resin, vistanex and the unsaturated carboxylic acid-modified vistanex.
Preferably, described organic resin film is any in polyolefin resin film, oriented polyester based resin film, oriented polyamide resin film and their aluminizer, applying silica film, plating di-aluminium trioxide film, the coating polyvinylidene chloride film of biaxial tension.
Preferably, described vistanex hot sealing layer is acrylic resin, polypropylene modification resin, polyvinyl resin, PE modified resin or their mixture.
Compared with prior art, the utility model has produced following beneficial effect:
Utilize the composite membrane that easily tears of the present utility model to make packaging bag, owing to form a plurality of projections on the surface of rigidity organic resin film, thereby increased the degree of roughness on rigidity organic resin film surface, specific surface does not arrange easier the tearing of rigidity organic resin film of projection, open the package so can free-handly tear in any position, packaging bag edge, satisfied user's user demand.
Description of drawings
The utility model will be further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is the more preferably structural representation of embodiment of composite membrane that easily tears of the present utility model.
The specific embodiment
As shown in Figure 1, the composite membrane that easily tears of the present utility model, it mainly is composited by vistanex hot sealing layer 2 and the surperficial rigidity organic resin film 1 that forms a plurality of projections 11.
Need to prove that the quantity of wherein said projection 11 is at least and can makes the user can free-handly tear with of the present utility model easily tearing the quantity of the packaging bag that composite membrane makes or greater than this quantity.
Particularly, the composite membrane that easily tears of the present utility model also comprises the barrier layer 3 of being located between described organic resin film 1 and the vistanex hot sealing layer 2; Described organic resin film 1 connects described barrier layer 3 by an adhesive layer 4; Described vistanex hot sealing layer 2 connects described barrier layer 3 by another adhesive layer 4.
Particularly, described barrier layer 3 is any in aluminium foil, aluminizer, applying silica film, plating di-aluminium trioxide film, coating polyvinylidene chloride film, ethylene-vinyl alcohol copolymer, the fluoropolymer polymer.
Particularly, described adhesive layer 4 is any in polyester-urethane resin, polyethers-urethane resin, isocyanate resin, vistanex and the unsaturated carboxylic acid-modified vistanex.
Particularly, any in the polyolefin resin film of biaxial tension, oriented polyester based resin film, oriented polyamide resin film and their aluminizer, applying silica film, plating di-aluminium trioxide film, the coating polyvinylidene chloride film of described organic resin film 1.
Particularly, described vistanex hot sealing layer 2 is acrylic resin, polypropylene modification resin, polyvinyl resin, PE modified resin or their mixture.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion should belong within the protection domain of the utility model claim all.
