Abstract
The utility model discloses a blister packaging substrate. According to the technical scheme of the utility model, the blister packaging substrate is a co-extruded sheet which is formed by extruding, casting, cooling and shaping a thermoplastic polymeric material, wherein the co-extruded sheet structurally comprises a first water-vapor blocking layer, an oxygen blocking layer and a second water-vapor blocking layer in sequence from outside to inside. The blister packaging substrate disclosed by the utility model has the advantages of a variety of materials and has high transparency, blocking properties and elastic modulus. In addition, hazardous substances can not generate in the process of processing, using, recovering and burning the blister packaging substrate, thereby the blister packaging substrate is an environment-friendly novel blister packaging substrate.
Description
Technical field
The utility model relates to the blister package field, particularly a kind of blister pack substrate.
Background technology
The blister package of medicine claims again blister (Press Through Packaging, PTP), first with behind the hard transparent plastic film plastics sucking moulding, the solid medicines such as tablet, pill, capsule are filled in the groove, be bonded together with the aluminium foil heating that scribbles adhesive, formation independently packs again.The medicine blister package has very large advantage: the medicine packing of dose at first is provided to the patient, and not only convenient but also economical; Secondly the performance of blister package protection medicine is good, and production efficiency is high, and cost is low, and the space that storage occupies is little, lightweight, convenient transportation; Moreover be exactly that security is good, owing to can be printed on explanatory note in the blister package, send out the generation that medicine person and pill taker all can avoid wrong medicine phenomenon.
In the market medicine blister package mainly is the polyvinyl chloride base material, the polyvinyl chloride base material is to add certain processing aid by Corvic, method by extruding, calendering processing is produced the product that meets medicinal requirements, it is as the base material of blister package, but every tablet of independent separate, pill or capsule make it to become minimum medicine packaging unit.Yet the poor-performing of obstruct steam, oxygen and the ultraviolet light of polyvinyl chloride base material in the medicine packing of extraordinary demand, is very restricted on the packaging applications such as tcm product powder, pill, granule.
In long-term use procedure, people have recognized the negative effect that polyvinyl chloride brings the mankind's living environment and organism gradually.At first, large, the side chain α chlorine atomic heat poor stability of cohesive energy between the strand of polyvinyl chloride, add and discharge easily poisonous vinyl chloride gas man-hour, must add plasticizer and heat stabilizer, to satisfy processing technology and to suppress the generation of self-catalysis degradation reaction, this will finally cause separating out of plasticizer and heat stabilizer in the use procedure, pollute packing material, and the harm pill taker is healthy; Simultaneously, in burning the polyvinyl chloride product process, there is the hydrochloric acid dioxin to produce and decomposes to produce hydrogen chloride gas, also seriously polluted human environment of surviving.
Since the medicine blister package desired transparent, hinder oxygen, special protection package requirements that block water steam and resistance high energy ultraviolet ray see through; do not have a kind of barrier polymeric material to satisfy the demands simultaneously, can obtain desirable blister pack substrate by the coextrusion casting with multilayer difference in functionality material.
Summary of the invention
The technical problem that the utility model solves has provided the blister pack substrate of a kind of environmental protection high-barrier, high elastic modulus.
The technical solution of the utility model is: a kind of blister pack substrate, it is characterized in that: described blister pack substrate be by the thermoplastic polymeric material by extrude, the coextrusion sheet of the method machine-shaping of curtain coating, cooling and shaping, the composition structure of this coextrusion sheet is followed successively by from outside to inside: steam barrier layer, oxygen barrier layer, steam barrier layer.Thermoplastic polymeric material described in the utility model is respectively modified polypropene and cyclic polyolefin.Steam barrier layer described in the utility model is the modified polypropene layer, because modified polypropene has narrower molecular weight distribution and side chain regularity, the water-resisting ability Effective Raise can be realized the obstruct to steam in the environment.Oxygen barrier layer described in the utility model is cyclic polyolefin layer, can effectively intercept airborne oxygen, avoids medicine oxidized rotten.Be added with ultra-violet stabilizer in the modified polypropene described in the utility model, the absorbing ultraviolet high-energy ray prevents that some from containing the catabolism of unsaturation medicine effectively.
Blister pack substrate of the present utility model has possessed the advantage of multiple material, existing higher transparency, high barrier, high elastic modulus, and all do not produce harmful substance in processing, use, recovery, the burning process, belong to environmentally friendly novel blister pack substrate, this blister pack substrate can satisfy the requirement with the bonding encapsulation of aluminium foil in addition.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Drawing explanation: 1, modified polypropene layer, 2, cyclic polyolefin layer.
The specific embodiment
Describe by reference to the accompanying drawings embodiment in detail.Blister pack substrate be by thermoplastic polymeric material's modified polypropene and cyclic polyolefin by extrude, the coextrusion sheet of the method machine-shaping of curtain coating, cooling and shaping, the composition structure of this coextrusion sheet is followed successively by from outside to inside: modified polypropene layer 1, cyclic polyolefin layer 2, modified polypropene layer 1.Modified polypropene layer 1 is as the steam barrier layer, because modified polypropene has narrower molecular weight distribution and side chain regularity, the water-resisting ability Effective Raise, can effectively realize the obstruct to steam in the environment, cyclic polyolefin layer 2 can intercept airborne oxygen effectively as oxygen barrier layer, prevents the medicine oxidation deterioration, be added with ultra-violet stabilizer in the modified polypropene, prevent that some from containing the catabolism of unsaturation medicine.That this blister pack substrate can satisfy simultaneously is transparent, blocking oxygen, obstruct steam and intercept the encapsulation requirement of the special protection that the high energy ultraviolet ray sees through, and is a kind of desirable blister pack substrate.
Above embodiment has described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; utilize above-mentioned disclosed thermoplastic polymeric material; by changing the order of each component of blister pack substrate; perhaps by increasing or reduce the blister pack substrate that component forms different structure; all drop within the protection domain of the present utility model; the utility model also has various changes and modifications, and these changes and improvements all fall in the scope of the utility model protection.
