Abstract
The utility model relates to a kind of novel aluminium film compound pearl cottons, it from the top down successively include aluminium film, the first pearl cotton layer, nonwoven layer, the second pearl cotton layer and aluminium film, the aluminium film is formed with the first pearl cotton layer and the second pearl cotton layer by direct hot pressing, and the nonwoven layer is Nian Jie by leaching membrane layer with the first pearl cotton layer and the second pearl cotton layer.The aluminium film is formed with the first pearl cotton layer and the second pearl cotton layer by direct hot pressing, adjust hot pressing temperature and pressure roller revolving speed and pressure and other parameters, so that it may effectively improve the adhesion strength of aluminium film and pearl cotton layer, and heat pressing process is simple, it is easy to control, lower production costs；Nonwoven layer can increase the toughness of compound pearl cotton, be not easily broken, and nonwoven layer is Nian Jie by leaching membrane layer with the first pearl cotton layer and the second pearl cotton layer, and bonding effect is good, is not easy delamination splitting, long service life.
Description
Technical field
The utility model relates to field of packaging material more particularly to a kind of novel aluminium film compound pearl cottons.
Background technique
Pearl cotton is polyethylene foam cotton, is non-crosslinked hole-closing structure, also known as EPE pearl wool, is a kind of novel environment friendly
Packaging material has many advantages, such as moisture-proof water proof, shockproof, sound insulation, heat preservation, also has good chemical resistance, is tradition
The ideal substitute of packaging material.Increase by one layer of aluminium film on ordinary pearl cotton surface and forms composite material, it is not only more beautiful,
And reflective moisturizing dampproof effect is good.But aluminium film and pearl cotton generally pass through adhesive and are bonded, and adhesion strength is poor, production
The bad control of process, has much room for improvement.
Utility model content
The purpose of this utility model is to provide more firm novel aluminium film compound pearl is bonded between a kind of each composite layer
Cotton.
Technical solution provided by the utility model are as follows: a kind of novel aluminium film compound pearl cotton successively includes aluminium from the top down
Film, the first pearl cotton layer, nonwoven layer and the second pearl cotton layer, the aluminium film and the first pearl cotton layer pass through direct hot pressing
At the nonwoven layer is Nian Jie by leaching membrane layer with the first pearl cotton layer and the second pearl cotton layer.
Wherein, the leaching membrane layer is that LDPE expects leaching membrane layer.
Wherein, the aluminium film is PET aluminizer, with a thickness of 50~80 μm.
Wherein, the PET aluminizes film surface equipped with anti-slip grid structure.
Wherein, the anti-slip grid structure is the up-small and down-big square cone protrusion of densely covered array.
Wherein, the nonwoven layer is nonwoven polypropylene fabric, with a thickness of 0.5mm.
Wherein, the second pearl cotton layer outer surface is additionally provided with aluminium film.
The utility model has the following beneficial effects: the novel aluminium film compound pearl cotton successively includes aluminium film, the from the top down
One pearl cotton layer, nonwoven layer and the second pearl cotton layer, the aluminium film are formed with the first pearl cotton layer by direct hot pressing, are adjusted
Whole good hot pressing temperature and pressure roller revolving speed and pressure and other parameters, so that it may the adhesion strength of aluminium film and pearl cotton layer is effectively improved,
And heat pressing process is simple, is easy to control, lower production costs；Nonwoven layer can increase the toughness of compound pearl cotton, be not easy
Rupture, nonwoven layer is Nian Jie by leaching membrane layer with the first pearl cotton layer and the second pearl cotton layer, and bonding effect is good, is not easy layering and opens
It splits, long service life.
Detailed description of the invention
Fig. 1 is the post-show cross-section map of novel aluminium film compound pearl cotton embodiment one described in the utility model；
Fig. 2 is the post-show cross-section map of novel aluminium film compound pearl cotton embodiment two described in the utility model.
Wherein, 1, aluminium film；2, the first pearl cotton layer；3, nonwoven layer；4, the second pearl cotton layer；5, leaching membrane layer；6, anti-skidding
Lattice structure；7, bubble film layer.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As the embodiment one of novel aluminium film compound pearl cotton described in the utility model, as shown in Figure 1, from the top down successively
Including aluminium film 1, the first pearl cotton layer 2, nonwoven layer 3 and the second pearl cotton layer 4, the aluminium film 1 passes through with the first pearl cotton layer 2
Direct hot pressing forms, and the nonwoven layer 3 is be bonded by leaching membrane layer 5 with the first pearl cotton layer 2 and the second pearl cotton layer 4.
In the present embodiment, 4 outer surface of the second pearl cotton layer also is provided with aluminium film 1, the aluminium film 1 and the second pearl cotton
Layer 4 is formed by direct hot pressing.
The aluminium film 1 of the novel aluminium film compound pearl cotton and the first pearl cotton layer 2 and the second pearl cotton layer 4 pass through directly heat
It presses, adjusts hot pressing temperature and pressure roller revolving speed and pressure and other parameters, so that it may effectively improve aluminium film 1 and pearl cotton layer
Adhesion strength, and heat pressing process is simple, is easy to control, lower production costs；Nonwoven layer 3 can increase compound pearl cotton
Toughness, be not easily broken, nonwoven layer 3 and the first pearl cotton layer 2 and the second pearl cotton layer 4 are be bonded by leaching membrane layer 5, bonding effect
Fruit is good, is not easy delamination splitting, long service life.
In the present embodiment, the leaching membrane layer 5 is that LDPE expects leaching membrane layer, expects lamination in non-woven fabrics LDPE by laminating machine
Between layer 3 and pearl cotton layer, bonding effect is good.
In the present embodiment, the aluminium film 1 is PET aluminizer, with a thickness of 50~80 μm.PET film surface of aluminizing is set
There is anti-slip grid structure 7, specifically, the anti-slip grid structure 7 is the up-small and down-big square cone protrusion of densely covered array.
In the present embodiment, the nonwoven layer 3 is nonwoven polypropylene fabric, and with a thickness of 0.5mm, tensile strength is 20~70N/
cm2。
In the present embodiment, the density of the second pearl cotton layer 4 is less than the density of the first pearl cotton layer 2, in this way
Just one side is harder for compound pearl cotton, and softer on one side, usually in actual use, softer one is inward-facing, and adequately protect product, compared with
Hard one faces out, and avoids external extrusion larger, is less susceptible to be punctured.
As the embodiment two of novel aluminium film compound pearl cotton described in the utility model, as shown in Fig. 2, not with embodiment one
It is that 4 outer surface of the second pearl cotton layer is equipped with one layer of bubble film layer 7 with place, 7 damping effect of bubble film layer is much big
In pearl cotton layer, when packing some friable products, advantage is huge, is able to achieve the protection effect that common compound pearl cotton cannot achieve
Fruit.Bubble film layer can be pasted on the second pearl cotton with cementing layer.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
