Abstract
The invention discloses an EPE block plaid aluminum membrane. The membrane is prepared by compounding EPE and an aluminum membrane through tape casting of a coating layer which is obtained by mixing an adhesive and a low density polyethylene resin particle, wherein an upper layer is the aluminum membrane, a lower layer is the EPE, another layer of the aluminum membrane can be compounded below the EPE through tape casting of a coating material of the coating layer, the usage amount of the low density polyethylene resin particle accounts for 30 to 50% of the weight of the coating material, and the thickness of the aluminum membrane is 10 to 25 mu m. Since the low density polyethylene resin particle is cheaper than the adhesive, the EPE block plaid aluminum membrane provided by the invention has reduced production cost while ensuring the compound quality of the EPE and the aluminum membrane.
Description
Technical field
The invention belongs to field of packaging material, relate to a kind of composite soft packaging material, be specifically related to the large grid aluminium of a kind of expanded polyethylene foam film.
Background technology
The EPE expanded polyethylene foam is a kind of packaging material of novel environment friendly, produces countless separated foams by low density polyethylene (LDPE) through physical blowing and consists of.It is frangible to have overcome common foamed glue, distortion, the shortcoming that recovery is poor, has the water proof protection against the tide, shockproof, sound insulation, insulation, plasticity is good, toughness is strong, reconstituted circularly, environmental protection, the plurality of advantages such as crashworthiness power is strong, also has good chemical resistance, be the ideal substitute of Traditional Packing material, be widely used in electronic apparatus, instrument and meter, computer, sound equipment, medicine equipment, the industry control cabinet, hardware and lamp decoration, handicraft, glass, pottery, household electrical appliances, spraying, the furniture family property, the high-grade frangible gift wrap such as drinks and resin, hardware, toy, melon and fruit, the inner packing of leather shoes, the packing of the multiple products such as commodity.
Aluminizer be adopt special process plastic sheeting plated surface last layer as thin as a wafer metallic aluminium and a kind of composite soft packaging material of forming, wherein the most frequently used processing method is when the vacuum aluminum-coated method of number, be exactly under high vacuum state, by high temperature metallic aluminium to be melted evaporation, the steam precipitation of aluminium is stacked on the plastic sheeting surface, thereby makes the plastic sheeting surface have metallic luster.Because it had both had the characteristic of plastic sheeting, have again the characteristic of metal, be that a kind of cheapness is attractive in appearance, function admirable, practical packaging material.At expanded polyethylene foam plated surface last layer metallic aluminium as thin as a wafer, and a kind of composite soft packaging material that forms.The application of aluminizer in composite packaging is very extensive, be mainly used at present that biscuit etc. is dry, in the external packing of dilated food packing and some medicine, cosmetics, be that a kind of cheapness is attractive in appearance, function admirable, practical packaging material, the aluminium film can substitute aluminium foil to a certain extent, but greatly reduce with the aluminium amount, not only saved the energy and material, also make comparatively speaking commodity packaging cost many.
The aluminizer compound package material has the following advantages:
1, greatly reduced and used the aluminium amount, saved the energy and material, reduced cost;
2, have good folding resistance and good toughness, pin hole and breach seldom occur, without the flexure crack performance, therefore the barrier of gas, water vapour, smell, the light etc. is improved;
3, have splendid metallic luster and good reflectivity, come package goods to play with it for a kind of gorgeous luxurious sensation of people and beautify commodity, the effect of improving commodity quality; And can process form colour film by coating, its decoration result be aluminium foil can't be obtained;
4, aluminium coated conducts electricity very well, and can eliminate electrostatic effect; Its sealing property is good, when especially packing powdery product, can not pollute closure part, has guaranteed the sealing property of packing;
5, have good gas barrier property, moist, the light-proofness of resistance and fragrance protectiveness, not only oxygen and steam had stronger barrier, and just can intercept all ultraviolet rays, visible light and infrared ray, can prolong storage life and the shelf life of content;
6. printing, the rear processing such as compound had good adaptability.
But in the compound process of aluminium film and expanded polyethylene foam curtain coating, need to use the coating materials such as adhesive, because the price of adhesive is higher, so that the cost of the large grid aluminium of expanded polyethylene foam film is relatively high.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides the large grid aluminium of the relatively cheap expanded polyethylene foam of a kind of cost film on the basis of not losing its performance.
The large grid aluminium of expanded polyethylene foam of the present invention film is composited through the coat curtain coating by expanded polyethylene foam and aluminium film, and the upper strata is the aluminium film, and lower floor is expanded polyethylene foam, and the coating material of described coat is the mixture of adhesive and ldpe resin particle.
Further can also be in the lower floor of expanded polyethylene foam again through the compound one deck aluminium of coat coating material curtain coating film.
Preferred coating material contains the ldpe resin particle of 30～50wt%.
Described aluminum membranous layer thickness is 10～25 microns, preferred 15～20 microns.
Because the price of ldpe resin particle is lower than adhesive, the large grid aluminium of expanded polyethylene foam of the present invention film has reduced production cost in the composite quality that has guaranteed expanded polyethylene foam and aluminium film.
Description of drawings
Accompanying drawing 1 is the structural representation of the large grid aluminium of single face expanded polyethylene foam of the present invention film;
Accompanying drawing 2 is the structural representation of the large grid aluminium of two-sided expanded polyethylene foam of the present invention film.
The specific embodiment
Below in conjunction with drawings and Examples the large grid aluminium of expanded polyethylene foam of the present invention film is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
With reference to accompanying drawing 1, the large grid aluminium of single face expanded polyethylene foam of the present invention film is composited 260 ℃ of left and right sides curtain coatings through the coat coating material by aluminium film 1 and expanded polyethylene foam 2, the upper strata is the aluminium film, lower floor is expanded polyethylene foam, with reference to accompanying drawing 2, the large grid aluminium of two-sided expanded polyethylene foam of the present invention film is by the first aluminium film 1, expanded polyethylene foam 2 and the second aluminium film 3 are composited 260 ℃ of left and right sides curtain coatings through the coat coating material, the upper strata is the aluminium film, the intermediate layer is expanded polyethylene foam, lower floor is the aluminium film, the coating material that adopts is the mixture of adhesive and ldpe resin particle, and the two is easy to curtain coating under liquid state compound, selects the coating material of different mixing proportion and the aluminum membranous layer of different-thickness to carry out contrast test.
Formed as coat by the adhesive of 70wt% and the ldpe resin mix particles of 30wt%, expanded polyethylene foam and aluminium film are composited 240 ℃ of lower curtain coatings, the aluminium film thickness is 10 microns.
Formed as coat by the adhesive of 60wt% and the ldpe resin mix particles of 40wt%, expanded polyethylene foam and aluminium film are composited 260 ℃ of lower curtain coatings, the aluminium film thickness is 18 microns.
