Problems solved by technology

[0003] As a very important form of packaging in pharmaceutical packaging, blisters are usually formed of plastic through blisters, etc., and the blisters are transparent and do not have an intercepting effect on ultraviolet rays. If the medicines in them are exposed to sunlight for a long time, they will affect the quality of the drug
[0004] In the packaging of medicines, the anti-counterfeiting marks are generally set on the outer packaging (such as cartons, etc.), and the blister packaging of medicines generally does not have anti-counterfeiting marks, and when the consumer loses the outer packaging after purchasing or the consumer only When less than one version of the drug is purchased, it is impossible to know the authenticity of the drug

Embodiment 1

[0034] The specific process of the preparation method of the anti-counterfeiting and anti-ultraviolet PVC hard sheet mentioned in the present invention is as follows:

[0035] 1). Dry the PVC pellets first, add the dried PVC pellets and anti-ultraviolet additives into the extruder to melt and extrude, wherein the melting temperature is 160-175°C, the extrusion thickness is 10.5-13mm, and the PVC pellets The mass ratio of material and anti-ultraviolet auxiliary agent is 70:30, and anti-ultraviolet auxiliary agent is selected from ultraviolet absorber UV-531;

[0036] 2). Place the extruded material obtained in step 1) on two cooling rollers to cool and solidify. The auxiliary equipment is an air knife. The distance between the air knife and the cooling roller is 2-2.5mm. The opening of the air knife is 3mm. The pressure is controlled at 0.25-0.35Mpa;

[0037] 3). The extruded material after cooling and solidification in step 2) is preheated by preheating rollers, and then stre...

Embodiment 2

[0043] The present invention provides a second embodiment of preparing a PVC hard sheet with laser anti-counterfeiting and anti-ultraviolet, the preparation method is the same as that of embodiment 1, the difference is that the mass ratio of PVC pellets to anti-ultraviolet auxiliary agent is 80:20, Anti-ultraviolet auxiliary agent is selected from ultraviolet absorber UV-327.

Embodiment 3

[0045] The present invention provides a third embodiment of preparing a hard PVC sheet with laser anti-counterfeiting and UV protection. The preparation method is the same as that of Embodiment 1, except that the mass ratio of PVC pellets to UV-resistant additives is 73:27.

[0046] Above-mentioned examples 2-3 all can make the PVC hard sheet that has anti-counterfeit laser and anti-ultraviolet, and the PVC hard sheet that makes can make blister PVC board by blistering, be used as medicine packing, can guarantee packing effectively. The quality of the medicines inside, prevent the medicines from being damaged by ultraviolet rays, and have anti-counterfeiting functions.

Abstract

The invention discloses a laser anti-counterfeiting and anti-ultraviolet drug bubble cap PVC solid sheet production method, which comprises: 1) adding a PVC granular material and an anti-ultraviolet auxiliary agent into an extruder to carry out melt extrusion; 2) carrying out cooling curing; 3) calendaring to prepare a PVC base material layer; 4) coating a laser layer on the PVC base material layer according to the typesetting specification; 5) carrying out primary curing on the position covered with the laser layer; 6) carrying out mold pressing on the laser layer; and 7) carrying out secondary curing on the laser layer. According to the present invention, with the method of the invention, the laser anti-counterfeiting and anti-ultraviolet PVC solid sheet can be prepared, and the bubble cap PVC plate can be prepared from the prepared PVC solid sheet through plastic suction and can be adopted for drug package, such that the drug quality in the package can be effectively ensured, the drug can be prevented from damage caused by ultraviolet rays, and the anti-counterfeiting function is provided.

Description

technical field [0001] The invention belongs to the field of preparation of plastic packaging materials, and in particular relates to a production method of a PVC hard sheet for anti-counterfeiting and anti-ultraviolet medicine blisters. Background technique [0002] In the field of medicine, because medicines are sensitive to ultraviolet rays and prone to chemical reactions, medicines cannot be exposed to sunlight (including ultraviolet rays) for a long time, but because not everyone can store medicines clearly and standardizedly, the said It is very necessary for pharmaceutical packaging to have anti-ultraviolet function. [0003] As a very important form of packaging in pharmaceutical packaging, blisters are usually formed of plastic through blisters, etc., and the blisters are transparent and do not have an intercepting effect on ultraviolet rays. If the medicines in them are exposed to sunlight for a long time, they will affect the quality of medicines. [0004] In th...
