Abstract
The utility model relates to the technical field of plastic film materials, and in particular relates to an auto-adhesive high-barrier packaging material. The auto-adhesive high-barrier packaging material provided by the utility model is sequentially provided with a printing layer, a first base material layer, a first bonding layer, a barrier layer, a second base material layer, a heat seal layer as well as a second bonding layer from top to bottom; the barrier layer is an aluminum foil layer; the first base material layer is a casting polypropylene film layer; the first base material layer is bonded on the barrier layer through the first bonding layer; and the second base material layer is a nylon film. The auto-adhesive high-barrier packaging material provided by the utility model has an excellent barrier effect, is high-temperature resistant and cooking resistant and has long service life; and the low-density polypropylene film is the second base material layer, has excellent chemical stability, heat seal property, water-proof property and damp-proof property.
Description
Technical field
The present invention relates to the plastic film material technical field, be specifically related to a kind of tack high-barrier packaging material.
Background technology
Packaging film is mainly extruded by several different resins mixing and is formed, has anti-puncture, the super-strength high-performance, the goods that is deposited on the supporting plate is carried out winding package, make packing material more firm clean and tidy, more superpower waterproof action is widely used, in foreign export, papermaking, five metals, plastics chemical industry, building materials, food pharmaceuticals industry.
At present commercially available packaging film all selects the material of aluminizing as barrier material, and compound more than two layers or two layers, such product cost is lower, and the packaging film that requires for high-barrier then difficulty reaches instructions for use.
Summary of the invention
In view of the defective that prior art exists, the objective of the invention is to provide a kind of tack high-barrier packaging material of barriering effect excellence.
The technical scheme that the utility model adopts is as follows:
The tack high-barrier packaging material, it is characterized in that: be followed successively by from top to bottom printed layers, the first substrate layer, the first adhesive layer, barrier layer, the second substrate layer, hot sealing layer and the second adhesive layer, described barrier layer is the aluminium foil material, the first substrate layer is the cast polypropylene film layer, and the first substrate layer adheres on the barrier layer by the first adhesive layer; The second substrate layer is nylon film.
Described hot sealing layer is low-density polyethylene film, and the second adhesive layer adopts adhesive for polyurethane.
The utlity model has following advantage: the utility model barriering effect is excellent, high temperature resistant, anti-boiling, and service life is longer, and to use low-density polyethylene film be the second substrate layer, has good chemical stability, heat sealability, resistance to water and moisture resistance.
Description of drawings
Fig. 1 is the structural representation of tack high-barrier packaging material.
Among the figure: 1, printed layers, the 2, first substrate layer, the 3, first adhesive layer, 4, barrier layer 5, the second substrate layer, 6, hot sealing layer, the 7, second adhesive layer.
The specific embodiment
Specify the utility model below in conjunction with accompanying drawing.
The tack high-barrier packaging material, it is characterized in that: be followed successively by from top to bottom printed layers 1, the first substrate layer 2, the first adhesive layer 3, barrier layer 4, the second substrate layer 5, hot sealing layer 6 and the second adhesive layer 7, described barrier layer 4 is the aluminium foil material, the first substrate layer 2 is the cast polypropylene film layer, and the first substrate layer 2 adheres on the barrier layer 4 by the first adhesive layer 3; The second substrate layer 5 is nylon film.
Described hot sealing layer 6 is low-density polyethylene film, and the second adhesive layer adopts adhesive for polyurethane.
Described barrier layer 4 is the aluminium foil material, has excellent barrier properties, improves simultaneously protection against the tide, shading, the corrosion resistant characteristic of material.
The first substrate layer 2 is the cast polypropylene film layer, is beneficial to improve material heat sealability, the thermophilic digestion of 121 ℃ of abilities, 30 min, oil resistivity, air-tightness are better, and heat seal strength is higher, and hot sealing layer 6 is low-density polyethylene film, has green non-poisonous free of contamination performance.
