Problems solved by technology

[0003] Existing pharmaceutical companies will use camera detection and automatic rejection system in the drug packaging process to detect whether all the holes on the packaging plate are filled with drugs. When the infrared equipment of the system detects whether the drug is leaked and filled, it is prone to reflections, and it is impossible to effectively determine whether there is a drug pressed in. It is prone to false detection and missed detection. It also needs to increase the manual re-inspection process, resulting in high labor costs and high detection costs. The problem of low efficiency cannot meet the requirements of modern enterprises for drug quality

Embodiment 1

[0025] An anti-reflective PVC composite film for pharmaceutical packaging, comprising the following components by weight: 100 parts of PVC resin powder, 20 parts of MBS resin (model BTA730), and 5 parts of a copolymer of methyl methacrylate and alkyl acrylate ( Model P-551J), 5 parts of octyl tin thiol, 0.4 part of lubricant.

[0026] The preparation method of the above-mentioned anti-reflection PVC composite film for pharmaceutical packaging comprises the following steps:

[0027] 1) Heat the PVC resin powder and MBS resin to 70°C with stirring, then add 1-2 parts of water-soluble epoxy resin, stir and heat to 85°C, add octyl tin thiol, polyethylene wax, methyl methacrylate and acrylic acid Alkyl ester copolymer, heated to 100 ℃ to dissolve;

[0028] 2) Take out of the pot, put it into a cold pot, quench it at 30-40°C, sieve it, and start the training machine to squeeze out air bubbles;

[0029] 3) The material is processed in turn by a calender, and five rolls are used for...

Embodiment 2

[0037] The preparation method of the anti-reflective PVC composite film for pharmaceutical packaging is the same as that in Example 1, wherein the composition of the composite film is shown in Table 1.

Abstract

The invention discloses an anti-reflective PVC (polyvinyl chloride) composite film for medicine packaging. The anti-reflective PVC composite film is prepared from the following components in parts by weight: 100 parts of PVC resin powder, 15-25 parts of MBS (methyl methacrylate-butadiene-styrene) resin, 2-5 parts of copolymer of methyl methacrylate and alkyl acrylate, 3.5-5.5 parts of octyl tin mercaptide and 0.3-0.5 part of lubricant. The anti-reflection PVC composite film for medicine packaging is a transparent film, and after being stamped, the transparent film changes color and becomes white from transparent, so that the anti-reflection PVC composite film does not reflect light during medicine packaging detection, the problem of light reflection is effectively solved, and the working accuracy of a camera detection automatic removal system is higher.

Description

technical field [0001] The invention belongs to the technical field of composite film production, and in particular relates to an anti-reflective PVC composite film for medicine packaging and a preparation method thereof. Background technique [0002] The composite film for pharmaceutical packaging is one of the most commonly used composite roll films. It is a film made of polyvinyl chloride (PVC) resin as the main raw material. It is used for blister packaging of solid pharmaceuticals (tablets, capsules, etc.) . As a pharmaceutical packaging material, its production process and performance have strict requirements. Medicine is a special commodity. Like other commodity packaging, the quality of medicine can directly affect the sales of medicines. [0003] Existing pharmaceutical companies use a camera detection automatic rejection system in the drug packaging process to detect whether the holes on the packaging board are all filled with drugs. When the infrared equipment ...
