Abstract
The utility model provides a two -sided heat -seal membrane, includes base film, base film's downside is connected with down the heat -seal layer, and base film's upside is connected with the heat -seal layer, goes up the upside on heat -seal layer and connects the corona layer, and corona layer upside is connected with the layer of aluminizing, the utility model discloses do not connect heat -seal layer and lower heat -seal layer at base film's both sides wind, very big improvement polypropylene membrane is as the ability of adhering to of intermediate course, still the corona layer is connected to the upside through on last heat -seal layer, on the corona layer upside connection layer of aluminizing for the thickness of film is more even, has also improved two -sided heat -seal membrane's the roughness of sealing simultaneously, has still strengthened two -sided heat -seal membrane's glossiness and separation nature, can also prevent that steam is at the surperficial knot fog of film.
Description
Technical field
The utility model relates to a kind of film, particularly a kind of Double-side hot sealer.
Background technology
Film is a kind of thin and soft transparent sheet, makes primarily of plastics, adhesive, rubber or other material.By the raw materials used classification of film forming: have polyethylene film, polypropylene film, polyvinyl chloride film and polyester film etc.And film is mainly used in the packaging to product, and be used as the coating layer of product surface.The share commercially shared along with plastics package and plastic packet product is increasing, and film has been widely used in the fields such as food, medicine, chemical industry.Wherein Double-side hot sealer is packaged as one of conventional packaging material, is generally used as intermediate course.At present, Double-side hot sealer is mainly used in food casing, two sides all can seal, but usually to there is thickness fluctuation large for existing Double-side hot sealer on market, the uneven shortcoming causing sealing formation degree difference of hot sealing layer, and the barrier of Double-side hot sealer is poor, easy at film surface knot mist after a long time use.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and the utility model provides that a kind of thickness is even, mist degree is little, glossiness is high, the Double-side hot sealer of high-barrier.
The utility model solves the technical scheme that its technical problem adopts: a kind of Double-side hot sealer, comprise base film layer, the downside of described base film layer is connected with lower hot sealing layer, and the upside of base film layer is connected with hot sealing layer, the upside of upper hot sealing layer connects corona layer, is connected with aluminium coated on the upside of corona layer.
As preferably, described base film layer is made up of polypropylene.
As preferably, described corona layer is that polypropylene surface is by the irregular film of the tool formed after high-frequency discharge process.
As preferably, described aluminium coated is incorporated into corona layer surface by the mode that vacuum evaporation or sputtering fly to plate.
As preferably, the thickness of described aluminium coated is 0.03 ~ 0.05 μm.
The utility model does not connect hot sealing layer and lower hot sealing layer at two crosswind of base film layer, improves the adhesive ability of polypropylene screen as intermediate course greatly; Also by connecting corona layer in the upside of upper hot sealing layer, on the upside of corona layer, connect aluminium coated, make the thickness of film more even, also improve the sealing formation degree of Double-side hot sealer simultaneously, also enhance glossiness and the barrier of Double-side hot sealer, can also prevent steam from tying mist at film surface.
Accompanying drawing explanation
Fig. 1 is a kind of hierarchy schematic diagram of the present utility model.
In figure: 1, base film layer, 2, lower hot sealing layer, 3, upper hot sealing layer, 4, corona layer, 5, aluminium coated.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment:
A kind of Double-side hot sealer as shown in Figure 1, comprise base film layer 1, base film layer 1 is made up of polypropylene; The downside of described base film layer 1 is connected with lower hot sealing layer 2, and the upside of base film layer 1 is connected with hot sealing layer 3, and the upside of upper hot sealing layer 3 connects corona layer 4, and corona layer 4 is that polypropylene surface is by the irregular film of the tool formed after high-frequency discharge process; Be connected with aluminium coated 5 on the upside of corona layer 4, aluminium coated 5 is incorporated into corona layer 4 surface by the mode of vacuum evaporation and the thickness of aluminium coated 5 is 0.04 μm.
The utility model does not connect hot sealing layer 3 and lower hot sealing layer 2 at two crosswind of base film layer 1, improves the adhesive ability of polypropylene screen as intermediate course greatly; Also by connecting corona layer 4 in the upside of upper hot sealing layer 3, aluminium coated 5 is connected on the upside of corona layer 4, make the thickness of film more even, also improve the sealing formation degree of Double-side hot sealer simultaneously, also enhance glossiness and the barrier of Double-side hot sealer, can also prevent steam from tying mist at film surface.
Through detecting, transverse tensile strength >=200MPa of the present utility model, longitudinal tensile strength >=120MPa, transverse breakage percentage elongation≤80%, longitudinal fracture percentage elongation≤200%, steam penetrating capacity≤2.5g/ (m2.24h), aluminize face wetting tension >=36Mn/m, aluminium coated adhesive force≤20%.
Above-described embodiment is one of the present utility model preferably scheme, not does any pro forma restriction to the utility model, also has other variant and remodeling under the prerequisite not exceeding the technical scheme described in claim.
