Abstract
The utility model provides a compound sheet of the polyvinyl chloride, the modified polypropylene, and the polyvinylidene chloride. The utility model comprises a polyvinyl chloride base layer, at least a layer of modified polypropylene compound layer and / or at lest a layer of polyvinylidene chloride compound layer which are compounded with the polyvinyl chloride base layer. A binding agent layer is arranged between the base layer and the compound layer or between compound layers. The utility model can be used for packing material for drugs, food or other objects, can effectively prevent drugs, food or other objects from deliquescence, molding and oxidizing and inactivation, and lengthens the guarantee period of drugs, food or other objects.
Description
Technical field:
The utility model and polyvinyl chloride, modified polypropene, polyvinylidene chloride composite hard sheet are relevant.
Background technology:
The material that is used for medical packaging now is a lot, as vial PE bottle, PP film, the hard sheet of PVC, aluminium foil etc.Use medicinal PVC, polyvinyl chloride in the eighties in 20th century, hard sheet is designated as the medical packaging material.The medicinal sheet material of PVC is a kind of packaging material cheaply, it has chemical resistance, stable chemical performance, the transparency is good, luminosity is good, light weight, mechanical performance is good and the waste disposal and the advantage such as easy of regenerating, but it is undesirable that its heel of Achilles is a barrier property, easily wets thoroughly, breathe freely, do not reach the requirement of medicine shelf-life.It is reported when plastic uptake blister package medicine is come with it in a lot of pharmaceutical factories, the one, on the tablet of wrapping, increase the shelf-life that a good packaging bag (as aluminium foil, PTP bag etc.) of barrier property guarantees medicine Lu again, this invisible cost that increases medicine, patient uses also inconvenient simultaneously.Packaging bag is once opening, and medicine can not once use up, and remaining medicine will the moisture absorption, oxidation, rotten.The 2nd, the medicine of supplying with pharmacy's sale is regained the pharmaceutical factory process again, both do not met the national drug systems of inquirie, influenced the quality of medicine again, increased the cost of medicine and the trouble of factory.Contain VCM among the PVC simultaneously and carcinogenic danger is arranged once excess.
The utility model content:
The purpose of this utility model is in order to overcome above deficiency, a kind of medicine, food or other article packing of being used for is provided, can effectively prevent medicine, food or other article deliquescence, go mouldy and oxidation deactivation, prolong medicine, food or the polyvinyl chloride of other article shelf-life, modified polypropene, polyvinylidene chloride composite hard sheet.
The purpose of this utility model is achieved like this:
The utility model polyvinyl chloride, modified polypropene, polyvinylidene chloride composite hard sheet comprise polyvinyl chloride basic unit, at least one deck modified polypropene composite bed and/or at least one strata vinylidene chloride composite bed compound with polyvinyl chloride basic unit.
Between above-mentioned basic unit and composite bed or between composite bed and composite bed adhesive layer is arranged, adhesive layer adopts polyurethane material.
Above-mentioned composite hard sheet comprises polyvinyl chloride basic unit, by compound modified polypropene composite bed or the polyvinylidene chloride composite bed of adhesive layer and polyvinyl chloride basic unit.
Above-mentioned composite hard sheet comprises polyvinyl chloride basic unit, by the compound modification polypropylene composite bed of adhesive layer and polyvinyl chloride basic unit, by adhesive layer and the compound polyvinylidene chloride composite bed of modified polypropene composite bed.
Polyvinylidene chloride (PVDC) also has performances such as self-extinguishment, fresh-keeping property and excellent protection against the tide, mildew-resistant except that the general characteristic with plastics, also have superior printing characteristics and sealing property simultaneously.PVDC is the best a kind of material of materials with high barrier property in the plastics package in the world today, and its wet thoroughly and oxygen permeating amount with numerous plastics relatively has very remarkable advantages.PVDC both had been different from polyvinyl alcohol, and barrier property sharply descends along with the moisture absorption increase, also is different from nylon membrane because water imbibition makes the moisture barrier property variation, but a kind ofly hinders high barrier material wet, that choke is all excellent.Polypropylene PP is except that the performance with general plastics, and aspects such as its mechanical strength, doubling degree, air-tightness, moistureproof anti-barrier, cold resistance all are better than common plastics, because its avirulence is safe and reliable.
The utility model composite hard sheet has utilized the characteristic separately of polyvinylchloride, PVF polyvinylidenechloride, polypropylene PP and has become a unified integral body respectively, to adapt to the requirement of solid medicine (tablet, capsule etc.), food or other article such as cosmetics, hardware packing, the medicine packing that the special requirement barrier property is good, can effectively prevent medicine, food or other article deliquescence, go mouldy and oxidation deactivation, prolong medicine, food or other article shelf-life.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the another kind of structural representation of the utility model.
The specific embodiment:
Embodiment 1:
Referring to Fig. 1, being compounded with PVF polyvinylidenechloride composite bed 3 (or modified polypropene PP composite bed) by adhesive layer 2 bondings in polyvinylchloride basic unit becomes the medicinal composite sheet of PVC/PVDC (or PVC/PP modified medicinal composite sheet).
Embodiment 2:
Referring to Fig. 2; In polyvinyl chloride basic unit 1, be compounded with modified polypropene composite bed 4, on modified polypropene composite bed 4, be compounded with polyvinylidene chloride composite bed 3 by adhesive layer 5, and become the PVC/PP/PVDC composite hard sheet by adhesive layer 2.
The PVC/PP/PVDC medicinal composite hard sheet is better than the hard sheet barrier property of PVC medicine, use as the blister package of medicine plastic uptake, can prevent effectively that medicine from separating tide, going mouldy and oxidation deactivation, prolong the medicine shelf-life, PVC/PP medicinal composite hard sheet cost is low, avirulence, performance and PVC/PP/PVDC composite hard sheet are approaching, can be used to replace the PVC/PVDC composite hard sheet to make solid medicinal packing high barrier material.
