Abstract

The utility model discloses a package, in particular to high seal hot band type package utilized to pack the medicine. Two layers of plastic membrane are adhered in turn on the two layers of aluminum foils or composite aluminum foils more than two layers. The middle adhesive layers of the package can be two layer or multi-layer. An aluminum foil 2 is adhered between a plastic layer 1 and plastic layer 3. A plastic layer 3 is adhered between plastic layer 1 and an aluminum foil 4. An AL layer is adhered on OPA layer or BOPP, PET and CPE layer. The AL layer or multi-layers are adhered after OPA layer or BOPP, PET and CPE layer are adhered. The package has the multi-layer seal and pressure resistance, and is strong and artistic. High leak-proof quality, good tenacity and high tensile strength are solved. An original property of a medicine curative effect can be maintained and not be damaged. The package has moisture-proof, guard against the ultraviolet radiation and guard against the property of medicine volatility. The performance-to-price ratio surpasses the overseas the allied product. The utility model has the advantages of low cost, high efficiency, short production cycle, quick delivery, excellent quality. The foreign exchange can be saved.

Description

The high sealing hot belt type plastic aluminum compound packing

1. technical field

The utility model relates to a kind of packing, especially for pharmaceutical packing.

2. background technology

The high sealing hot belt type plastic aluminum compound packing is high-grade medicine, food, chemical industry, the high leakproofness of pharmaceuticals industry employing, anti-property of medicine volatilizations such as antiphlogistic, a kind of packing of ultraviolet radiation preventing.It is the emerging product of domestic and international medical packaging.This drug packaging is high to material requirements, and it requires these packing to stamp out the trade mark or the sign degree of depth of 6.5 ~ 8.5C at least on the packaging foil surface, and is configured as the rectangle concavity.The packing that is shaped must not rupture, is out of shape, comes off, delamination.And high sealing hot belt type packaging aluminium thickness should reach 10 more than the C.At present the thickness of two layers of composite material producing of Japan only reaches 6.5 C, makes the producer can't formed package and return goods in use.High sealing hot belt type packaging aluminium in the known technology is the bonding AL of OPA (two layers are bonding) normally, or with 3 C nylon and two layers of composite material of 7 C aluminium foils.And aluminium foil easily splits and tension not, and the packing after the shaping is softer, and is not strong not attractive in appearance, and leak tightness is poor, and the literal of punching press or the trade mark degree of depth are not enough.Because packing of this product aluminium is difficult to breakthrough on thickness, color, surface gloss, compound toughness, anti-peel force five big technical barriers, thereby domesticly still there is not a manufacturer.Can reach producer that product design requires in the known technology and have only German Louth Ma Dun company.The two-layer compound packing price height of its production, the order cycle is long, reaches three or four months, has increased the production cycle of drug packaging, and waste is big, causes drug packaging production efficiency to descend.

3. utility model content

The purpose of this utility model is at weak point of the prior art, and a kind of employing MULTILAYER COMPOSITE is provided, and more high leakproofness is arranged, and strong withstand voltage, the high sealing hot belt type plastic aluminum compound packing that presentation quality is good.

The purpose of this utility model is achieved in that a kind of protection against the tide, volatilization prevention of being used for, the ultraviolet radiation preventing packing, high sealing hot belt type plastic aluminum compound packing especially for medicine, its special compound aluminium of moulding that is two layers of bonding successively two layers of aluminium foil of plastic layer or above level, at bond plastic layer 3 between bonding aluminium foil layer 2 and the aluminium foil layer 4 between plastic layer 1 and the plastic layer 3, adhesives is made packing then.In this intermediate adhesion layer can be one or more layers, and its material can be that aluminium foil reaches up to the plastic material because of coefficient.

Packing described in the utility model mould aluminium and mould packaging aluminium bonding between the aluminium can be more than four layers or four layers to mould aluminium compound.

The utility model compared with prior art has following good effect:

Because the utility model adopts multilayer bondingly to mould aluminium in the composite packaging process, moulds aluminium multilayer or more multi-layered bonding, can make to mould and bondingly between the aluminium adhere to mutually, complementary not enough, make more strong, attractive in appearance and tool high leakproofness after the packing formation.Bigger toughness and tensile strength are arranged.Original not catabolism of property of medicine curative effect be can keep, medicine good airproof performance, protection against the tide, ultraviolet radiation preventing, the anti-property of medicine volatilization of packing made.Cost performance is better than external like product.Have that cost is low, efficient is high, with short production cycle, delivery is fast, quality is good, can save the characteristics of foreign exchange.

4. description of drawings

Fig. 1 is a kind of structural representation of the present utility model.

5. embodiment

Fig. 1 shows the embodiment of the utility model by the hot sealing moulding.Because the packaging aluminium material of dry compound machine combined shaping, domestic each big aluminium manufacturer can produce the above aluminium foil sheet material of 8 C, the surface is all very coarse, the color spot is too many, uneven, in moulding the aluminium recombination process, bubble is arranged, compound tightness is not enough, surface quality and outward appearance are very ugly, and toughness and tension degree can not reach requirement.Consider that aluminium foil is a metal, metal and metal be high density composite directly.So ground floor with nylon PA and the compound employing high-temp high-viscosity of aluminium foil and color mould aluminium compound and after can meet the requirements of material.The utility model adopts the MULTILAYER COMPOSITE principle for this reason, moulds bonding the making of plastic-aluminum aluminium with multilayer and packs.When bonding with two layers of bonding successively two layers of aluminium foil of plastics or the above compound aluminium of moulding.At bond plastic layer 3 between bonding aluminium foil 2 and the aluminium foil layer 4 between plastic layer 1 plastic layer 3, select at compound tense that multiple to mould aluminium bonding successively for use.The bonding available aluminium foil of interlayer reaches up to the plastic material because of coefficient.So that thickness, color, surface gloss and toughness, anti-peel force and shock-resistant on reach external like product level.

Another embodiment of the present utility model can be mould between the plastic-aluminum aluminium bonding or more multi-layeredly mould packing bonding between the aluminium, be OPA or BOPP, the bonding OPA of the bonding AL of PET, CPE or BOPP, PET, the bonding AL of CPE totally four layers compound or more multi-layered above bonding, and then be coated with and be stained with mixture.The drug packaging that is shaped of MULTILAYER COMPOSITE thus, thickness, color, surface gloss and toughness, anti-peel force and shock-resistant on reach external like product level.

Packing described in the utility model can be to mould aluminium and mould be bonded as four layers or be most preferred embodiment of the present utility model than four layers of more multi-layered bonding packing between the aluminium.
