Abstract
The utility model provides a kink membrane, includes base film, base film's downside is connected with the heat -seal layer, and base film's upside is connected with the corona treatment layer, and the upside on corona treatment layer is connected with the layer of aluminizing, and base film is for the polypropylene and increase firm nucleating agent composition. The utility model discloses added in polypropylene the inside and increased firm nucleating agent, the rigidity of very big improvement polypropylene, can make flexibility factor improve 20 -30%, improve dimensional stability, comprise heat -seal layer, base film, corona treatment layer complex, the corona treatment layer is for having concavo -convex film for the film has good thickness homogeneity and good 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 torsion film.
Background technology
Kink is packaged as one of the most traditional candy wrapping mode, it and pillow bag, sling N pack claim candy wrapping three large manner of packing.The main material of kink packaging converts ep-type material PET torsion film to by original PVC.
Along with the continuous increase of the market demand, the product of knot film and material therefor are also upgrading day by day.The new product development of CPP mainly concentrates on ultra-low temperature heat sealing film, cold-resistant film, Tropical cooking film etc.The film of some specific uses, also among Application and Development, as antistatic film, agricultural chemicals film, high transparency surpass soft film etc. and introduce to the market just gradually, captures new application.
But the rigidity of knot film circulated in the market is little, easily break in the process of packaging, and mist is also easily tied in the surface of film, greatly hinder knot film in the market be applied to development.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, the torsion film that the utility model provides a kind of high rigidity, mist degree is little, glossiness is high, kink performance is good.
The utility model solves the technical scheme that its technical problem adopts: a kind of torsion film, comprise base film layer, the downside of described base film layer is connected with hot sealing layer, the upside of base film layer is connected with corona processing layer, the upside of corona processing layer is connected with aluminium coated, and described base film layer is polypropylene and reinforcement nucleating agent composition.
As preferably, described corona processing layer is that polypropylene surface is by the irregular film of the tool formed after high-frequency discharge process.
As preferably, the mode that described aluminium coated flies to plate by vacuum evaporation or sputtering is incorporated into corona processing layer surface.
As preferably, the thickness of described aluminium coated is 0.03 ~ 0.05 μm.
The utility model with the addition of reinforcement nucleating agent inside polypropylene, improves polyacrylic rigidity greatly; Bending coefficient can be made to improve 20-30%, improve dimensional stability; Be made up of hot sealing layer, base film layer, corona processing layer compound, corona processing layer is the irregular film of tool, makes film have good thickness evenness and good barrier, 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, hot sealing layer, 3, corona processing layer, 4, 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 torsion film as shown in Figure 1, comprises base film layer 1, and base film layer 1 is polypropylene and reinforcement nucleating agent composition; The downside of described base film layer 1 is connected with hot sealing layer 2, and the upside of base film layer 1 is connected with corona processing layer 3, and corona processing layer 3 is that polypropylene surface is by the irregular film of the tool formed after high-frequency discharge process; The upside of corona processing layer 3 is connected with aluminium coated 4, and aluminium coated 4 is incorporated into corona processing layer 3 surface by the mode of vacuum evaporation, and the thickness of aluminium coated 4 is 0.25 μm.
The utility model with the addition of reinforcement nucleating agent inside polypropylene, improves polyacrylic rigidity greatly; Bending coefficient can be made to improve 20-30%, improve dimensional stability; Be made up of hot sealing layer 2, base film layer 1, corona processing layer 3 compound, corona processing layer 3 is the irregular film of tool, makes film have good thickness evenness and good barrier, can also prevent steam from tying mist at film surface.
Through detecting, transverse tensile strength >=25MPa of the present utility model, longitudinal tensile strength >=35MPa, transverse breakage percentage elongation >=450%, longitudinal fracture percentage elongation >=350%, 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.
