Abstract
The invention relates to an easy-to-tear type drug packaging composite film for an automatic drug dispensing machine. The preparation method of the easy-to-tear type drug packaging composite film comprises the following steps: coating the surface of a polyester film to change the molecular structure of the polyester film; then, gluing the treated polyester film through a gluing device and drying; adding a lot of low-temperature heat-sealing materials in the film blowing process of the polyester film to obtain a low-temperature heat-sealing film; printing and compositing the polyester film (PET) and a polyethylene film (LDPE) to obtain a composite film, and finally performing curing, slitting, bag making, edge folding and packaging, so that the low-temperature heat-sealing easy-to-tear type composite film is obtained. The composite film overcomes the defects that in the prior art, the composite film is not easy to tear, used glass paper is high in cost, and the hot-sealing temperature is high. The composite film is good in application performance, convenient for packaging, good in moisture resistance performance, light in materials and good in drug resistance, thereby effectively protecting the quality of drugs, and being particularly suitable for being used in hospitals.
Description
Technical field
The present invention relates to technical field of medicine packaging, specifically refer to auto-dispensary machine easy-tear type pharmaceutical packaging composite membrane.
Background technology
In Europe, Korea S, the full-automatic drug putting machine of Taiwan Deng Di hospital used very general, can not only improve the operating efficiency of hospital, can also reduce error rate, only need hand over after money patient, prescription information is transferred to " auto-dispensary machine ", auto-dispensary chance is selected medicine automatically, improves security performance.In American-European countries's use amount, steadily also there is every year 10% growth.At present domestic hospitals this medicine auto-dispensary machine that also starts to come into operation, will be certain at Chinese various big hospital universal future.
Use auto-dispensary machine just the sealed membrane of auto-dispensary machine to be had to requirement, should meet Medicine Package Bag and have good intensity, frangible pouch, does not avoid inner medicine to receive the pollution of extraneous bacterium environment, also to require it to there is tearability, the convenience that guarantee is used simultaneously.And traditional polythene material has good heat sealability, also just mean that the edge sealing place of packaging bag is not easy to tear; The composite membrane easily tearing as improvement more use now, this composite membrane selects glassine paper and polyethylene and aluminium foil to be composited, and needs the glassine paper of a large amount of use imports, has greatly increased the production cost of product.In addition, the bag medicine film of applying on market exists that heat-sealing temperature is high causes being unfavorable for practical operation, and temperature is high can be to shortcomings such as medicine exert an influence.
Summary of the invention
The technical problem to be solved in the present invention is: auto-dispensary machine easy-tear type pharmaceutical packaging composite membrane is provided, the composite membrane of preparing by this technique has solved and in prior art, has had not easily openable of composite membrane, use glassine paper cost high, the defect that heat-sealing temperature is higher, is particularly suitable for hospital's special use.
For solving the problems of the technologies described above, technical scheme provided by the invention is:
Auto-dispensary machine easy-tear type pharmaceutical packaging composite membrane, comprises following step of preparation process:
(1) processing of polyester film (PET): polyester film surface is changed to the molecular structure of polyester film film through coating; Polyester film film adopts the technique of corona coating surface, on rewinding machine, install corona treatment plant additional, this device corona intensity is high, by high frequency transformer, produce high-frequency and high-voltage, and be transported on discharge plate by high-frequency and high-voltage cable, corona roller (silica gel roller) is discharged, now the air of two interpolars of discharge plate and corona roller is able to corona ionization, then there is the blue spark of a slice, make to be able to effective processing by the film between discharge electrode;
(2) by polyester film process glue spreading apparatus gluing, oven dry after step (1) is processed;
(3) printing process: the polyester film (PET) of processing through step (2) is placed on printing machine discharging frame, through tenslator and deflector roll, enter chromatography the first look device (print out pattern and character then enter drying tunnel dry), dry, enter chromatography the second look device, dry ... N look device, dries, until all color printing enters wrap-up, rolling rolling film through traction position after completing; Its idiographic flow technique is: unreel → tension force of polyester film control → chromatography the first look → dry → chromatography the second look → dry → chromatography the 3rd look → dry → chromatography N look → dry → traction → rolling;
(4) processing of polyethylene film (LDPE): polyethylene film is added in blown film process 40%～50% heat-sealable material make temperature 70 ℃～85 ℃ can involution heat-sealing films; Heat-sealable material is bought in Jiangsu Tong Li Chemical Co., Ltd.;
(5) compound working procedure: the polyester film (PET) after step (3) step (4) is processed and polyethylene film (LDPE) are carried out compound, compoundly make volume film by wrap-up;
(6) curing step: the volume film after step (4) is processed, at 45 ~ 55 ℃ of temperature of curing chamber, is processed to 30 ~ 60h; (7) divide cutting process: by the volume film cutting machine rolling after step (5) is processed, bag, flanging, packing.
Preferably, the polyester film in described step (1) adopts the technique of corona coating surface, installs corona treatment plant on rewinding machine additional.
Preferably, the gluing in described step (2), glue-spread is 1g/m
2-3g/m
2, dry as selecting temperature 50-80 ℃.
Adopt above processing step, tool of the present invention has the following advantages:
(1) by the processing to polyester film (PET), former polyester film surface is changed to the molecular structure of film itself through coating, thereby reach the effect of easily tearing, composite membrane any direction, the position of making can free-handly be torn, and difficult because tear the breakage that causes packing by mistake.By the technique of corona coating surface, darker than general thin sided corona treatment, intensity is larger, make this film surface form fine and close mesh, make the molecular chain rupture of film itself, the intensity of its processing can regulate as requested at any time, makes it reach the existing effect of easily tearing, and has again the easily tore film of film primary characteristic.
(2) composite membrane after processing by compound working procedure has low-temperature heat-sealing and easily tears double effects, not only improved the operating efficiency of drug putting machine, convenient operation, and also easy to use, sanitation performance has also reached the relevant criterion of national cartridge bag material, is applicable to very much hospital and uses.
(3) film being composited by adhesive by polyester film and low density polyethylene films not only applicable performance is good, is convenient to packing, also very outstanding aspect moisture barrier property, and material is light, and drug resistance is good, thereby has effectively protected the quality of medicine.
