Abstract
The utility model discloses a novel VMPET aluminized film of separating nature of high resistant, include the skin, barrier layer, linear low density polyethylene rete and the protective layer that stack in proper order, barrier layer adoption poly(ethylene terephthalate) (PET) rete, thermoplastic acrylic resin and the compound realization of layer multipass of aluminizing, the thickness scope on the layer of aluminizing is 450 -520A.
Description
Technical field
This utility model relates to a kind of novel VMPET aluminizer with high obstructing performance for packing article.
Background technology
VMPET is polyester aluminizer, and it has excellent physical and mechanical properties in wider temperature range, and life-time service temperature is up to 120 DEG C, electrical insulating property is excellent, and even under high-temperature high-frequency, its electrical property is still better, creep resistance, fatigue durability, rub resistance, dimensional stability are all fine. Aluminizer is a kind of composite soft packaging material adopting special process to plate the very thin metallic aluminium of last layer in Plastic film surface and being formed, the processing method of most common of which is when the vacuum aluminum-coated method of number, it is exactly by high temperature, metallic aluminium is melted evaporation under high vacuum state, the steam precipitation making aluminum is stacked in Plastic film surface, so that Plastic film surface has metallic luster.
VMPET metallized film is usually the aluminizer that multilayer film is constituted, both there is the characteristic of plastic sheeting due to it, there is again the characteristic of metal, the effect that film surface is aluminized is shading, resisting ultraviolet radiation, both the shelf-life of content had been extended, improve again the brightness of thin film, instead of aluminium foil to a certain extent, also there is performance inexpensive, attractive in appearance, therefore, aluminizer application in composite packaging is very extensive, is currently mainly applied in the outer package of dry, the puffed food packagings such as cookies and some medicine, cosmetics. Particularly with perishable class I goodss such as food, medicine, cosmetics, pesticide, articless for washing, it is usually and adopts the aluminized complex film of high obstructing performance to realize.
Current packaging field is by selecting barrier film material as being deposited with sull, aluminium foil and vacuum plated aluminum film etc., through going over (or multipass) compound to meet the packing instructions of the high obstructing performance of above product. But evaporation sull is transparent material, it is impossible to be applied to the occasion kept in Dark Place. And when adopting the method for aluminium foil, use the aluminizer that blocked up aluminium foil realizes to be easily broken off, more limit use occasion.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes the novel VMPET metallized film of a kind of high barrier, existing aluminizer is improved, it is effectively improved barrier property so that it is the packaging for perishable class I goodss such as food, medicine, cosmetics, pesticide, articless for washing also can be suitable for.
In order to solve above-mentioned technical problem; this utility model be employed technical scheme comprise that; a kind of novel VMPET metallized film of high barrier; including the outer layer stacked successively, barrier layer, linear low density polyethylene (LLDPE) rete and protective layer; barrier layer adopts polyethylene terephthalate (PET) rete, thermoplastic acrylic resin layer and aluminium coated compound to realize, and the thickness range of aluminium coated is 450-520A(angstrom).
Described outer layer is polyethylene terephthalate (PET) rete or o-phenyl phenol rete or polyvinylidene chloride (PVDC) rete. Polyethylene terephthalate film layer (adopts polyethylene terephthalate to make), o-phenyl phenol rete (adopting o-phenyl phenol to make), polyvinylidene chloride rete (adopting polyvinylidene chloride to make) etc. are all have the rete that the material of excellent barrier properties is made.
Wherein, linear low density polyethylene (LLDPE) rete is to adopt linear low density polyethylene (LLDPE) material to make, and linear low density polyethylene (LLDPE) (LINEARLOWDENSITYPOLYETHYLENE, LLDPE) is that ethylene is with senior on a small quantityThe copolymer that-alkene is polymerized in the presence of a catalyst.
The thickness of aluminium coated is typically smaller than 400A, because thickness is excessive is easily reduced peel strength. In this utility model, its barrier layer adopts thermoplastic acrylic resin layer to increase the adhesion between polyethylene terephthalate film layer and aluminium coated, and then improve the tack of aluminium coated, therefore, thickness can be increased between 450-520A by aluminium coated of the present utility model, and then substantially increases the barrier of this aluminizer.
Further, printing layer it is additionally provided with between described protective layer and linear low density polyethylene (LLDPE) rete.
This utility model passes through such scheme, thermoplastic acrylic resin layer is adopted to make polyethylene terephthalate film layer and aluminium coated strong bonded as bonding coat, improve the combined strength bination of whole aluminizer, aluminum layer thickness is brought up to 450-520A simultaneously, greatly strengthen the barrier of aluminizer. Additionally, the outer layer (polyethylene terephthalate film layer or o-phenyl phenol rete or polyvinylidene chloride rete) adopting excellent barrier properties further increases barrier property so that it is the packaging for perishable class I goodss such as food, medicine, cosmetics, pesticide, articless for washing also can be suitable for.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of embodiment of the present utility model.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
As a specific embodiment; referring to Fig. 1; the novel VMPET metallized film of a kind of high barrier of the present utility model; including the outer layer 1 stacked successively, barrier layer 2, linear low density polyethylene (LLDPE) rete 3 and protective layer 4; barrier layer 2 includes polyethylene terephthalate (PET) rete 21, thermoplastic acrylic resin layer 22 and the aluminium coated 23 that stack gradually, and polyethylene terephthalate film layer 21, thermoplastic acrylic resin layer 22 and aluminium coated 23 are carried out multipass compound realization. Printing layer 5 it is additionally provided with between protective layer 4 and linear low density polyethylene (LLDPE) rete 3.
Outer layer 1 can adopt polyethylene terephthalate (PET) rete or o-phenyl phenol rete or polyvinylidene chloride (PVDC) rete to realize. Polyethylene terephthalate film layer is to adopt polyethylene terephthalate to make, o-phenyl phenol rete is to adopt o-phenyl phenol to make, polyvinylidene chloride rete is to adopt polyvinylidene chloride to make, and above-mentioned material is all the material with excellent barrier properties.
The thickness range of aluminium coated 23 is 450-520A(angstrom). The thickness of traditional aluminium coated 23 is typically smaller than 400A, because thickness is excessive is easily reduced peel strength. In this utility model, its barrier layer 2 adopts thermoplastic acrylic resin layer 22 to increase the adhesion between polyethylene terephthalate film layer 21 and aluminium coated 23, and then improve the tack of aluminium coated 23, therefore, thickness can be increased between 450-520A by aluminium coated 23 of the present utility model, and then substantially increases the barrier of this aluminizer.
Wherein, linear low density polyethylene (LLDPE) rete 3 is to adopt linear low density polyethylene (LLDPE) material to make, and linear low density polyethylene (LLDPE) (LINEARLOWDENSITYPOLYETHYLENE, LLDPE) is that ethylene is with senior on a small quantityThe copolymer that-alkene is polymerized in the presence of a catalyst.
Although specifically showing in conjunction with preferred embodiment and describing this utility model; but those skilled in the art should be understood that; in the spirit and scope of the present utility model limited without departing from appended claims; this utility model can be made a variety of changes in the form and details, be protection domain of the present utility model.
