Inventory pharmaceutical packaging materials and packaging structure

Pharmaceutical packaging film strict in security, plastic flexible packaging film as an important drug packaging materials, selection of materials is very important. Here are the materials and application characteristics of pharmaceutical packaging film related finishing, for your reference. To the flexible packaging film material requirements of the following to prevent content, its main measures are well protected against dampness, choke, avoid light, sterile, seal; In order to ensure that the quality of the content and packing, storage and transportation safety in the process of filling, also requires packaging materials have to ensure that content stability, heat resistance and migration does not produce harmful health performance; Required materials has certain stretching resistance, impact resistance, durability and health properties such as resistance to tear strength. Chinese and western medicine used in plastic composite film materials species because of the monolayer film at present can't meet the above all sorts of function at the same time, the basic use multilayer composite floor or second floor above of multilayer composite film or coating film. Of Chinese and western medicine granules, powder, powder, capsule, the plastic composite film packaging mainly has the following several varieties. LDPE film LDPE with a variety of polyolefin composite made of flexible packaging bags, as a kind of medicinal liquid packaging bags, its raw material is LDPE and ethylene - Alpha olefin copolymer. Advantages: can withstand the above 100 ℃ high temperature sterilization, and has good flexibility, use the raw materials such as LDPE, adhesive, PA of multilayer composite films, possesses the advantages of similar to PVC, PP, wide range of USES. BOPP film PP film can be a large number of used medical interior and exterior layer of flexible packaging composite film material. Advantages: two-way stretch polypropylene ( BOPP) Film has the good transparency, heat resistance and barrier property; It is used for the outer layer of the compound bag, with good sex of heat sealing LDPE, EVA, EEA, EAA or aluminum foil, can greatly improve the rigidity and the physical and mechanical properties of the composite membrane. Such as in BOPP film coated with moistureproof and good barrier property of PVDC, can greatly improve the wet gas resistance and resistance performance. The CPP film cast polypropylene film ( CPP) Good heat sealing, usually for the lining of the composite bags, vacuum aluminum plating can then with BOPP, PET, OPA, PT compound, is an important material of drug packaging. PET film advantages: polyester film ( PET) The two-way stretch polyester film has high mechanical strength and rigidity, high heat resistance, resistance to drugs is wonderful, very good transparency and gloss, water vapor and oxygen transmittance is lesser, have very good smell of sex, this is all the other film incomparable. PVDC film poly (vinylidene chloride film ( PVDC) Barrier property is one of the best films, divided into heat resistance coating film, such as carbamate resistance of PP, CPE, PET and PVDC coated film. PVDC coated composite films have been widely used in pharmaceutical packaging, can play a role, flavor, moisture resistance, etc. It is understood that PVDC currently on the market is actually the vinylidene chloride ( 伏直流电) With vinyl chloride or copolymer of acrylic acid monomer, monomer content often is 75% ~ 90%. Advantage: PVDC has a transparent, flexible, oil resistant, resistant to chemicals, as well as the outstanding characteristics of carbamate resistance and resistance to wet, colleges and universities is one of the widely used block material. Application: in the high block pharmaceutical packaging, it is usually used as coating material, in PP, CPE, PET film coating 2 ~ 4 & micro; MPVDC composite membrane, can make its air permeability, moisture permeability are best suited for manufacturing pharmaceutical blister packaging film and the composite bags of grain, powder low price drugs. Vacuum aluminum plating film vacuum aluminum plating film is in the condition of high vacuum aluminum evaporation to various base on the membranes of the product of a kind of flexible packaging film, aluminum plating layer is very thin. In important powder, granules, powder widely used in packaging has PETP, CPP, PT, PI, PE and so on vacuum aluminum plating film. Among them, the largest number of applications, PETP, CPP, PE vacuum aluminum plating film. Advantage: soft vacuum aluminum plating film packaging not only have the characteristics of the plastic base, but also has beautiful decorative and good barrier property, especially all kinds of plastic base material after aluminum plating, its light transmittance, oxygen transmission rate, and through steam rate reduce dozens of times or one hundred times, for drug packaging, can prevent drug mildewy, moisture deterioration. CTFE thin-film fluorine halogenated hydrocarbon is mainly refers to three fluorine chlorine triene ( CTFE） The copolymer, nonflammable, good barrier property and transparent, has a unique range of application. There are two types of the film that CTFE ethylene vinyl chloride copolymer are three. According to coating online know, CTFE film in - 160 ℃ still is soft, melting point between 180 ~ 204 ℃, and its taste and the degree of crystallization. Multi-layer co-extrusion medical packaging film multilayer structure medical packaging film usually use adhesives/adhesive/PA/PE/PE/adhesive/PA/adhesive/PE9 layer structure, also can use PP instead of PA, other structure, thickness is usually to 0. 05 ~ 0. 4mm。 Currently co-extrusion film layers are on the increase, there have been many companies can produce 8, 9 and 11 layers of medical packaging film. Several typical pharmaceutical compound packaging structure (1) general use: BOPP/PE, PET/PE, BOPA/PE, BOPA/CPP, PET/VMCPP, BOPP/VMPET/PE, BOPP/PE/AI. (2) the surgical blades: AI/PE, BOPP/PET/al/PE. (3) blister packaging: PVC/AI, PVC/VC - VA / AI, PP / PVC / PP、PF / PVC / PE。 (4) powder, tablets, paper/al/PE, paper/PE/al/PE. 5. Paste class: PET/al/PE. 6 infusion packaging: PET/Tie/POE/CPP, HPP + + Sebs/Sebs / / RCP terPP + Sebs. Source: the membrane flux WeChat public number
