200-300μm Glossy Bright White Opaque PVC Rigid Film for Pharmaceutical Blister Packaging
This product is an opaque PVC rigid film specifically customized for pharmaceutical blister packaging. Its core specifications focus on a thickness range of 200-300μm, featuring a glossy bright white surface texture. It possesses excellent physical properties, chemical stability, and compliance, making it an ideal choice for ensuring the safe storage of pharmaceuticals and enhancing the visual appeal of packaging.
In terms of material characteristics, this PVC rigid film uses high-purity polyvinyl chloride resin as the core raw material, processed through precision co-extrusion molding. The processing temperature and extrusion rate are strictly controlled during the molding process. The typical co-extrusion processing temperature range is 160-190℃, and the extrusion rate is adapted to the equipment model, ranging from 30-50 kg/h, to ensure complete melting and mixing of the raw materials. The finished product exhibits excellent overall uniformity, with a thickness tolerance controlled within ±10μm, ensuring consistent molding during blister packaging. The glossy surface undergoes special corona treatment, with a treatment strength of 38-42 dyn/cm, to ensure a smooth and flawless surface. This not only enhances the bright white visual effect of the packaging, facilitating the printing of key information such as drug information and brand logos, but also reduces friction with the mold during the blister packaging process, minimizing molding defects. The opaque properties are achieved through precise proportioning of light-blocking components, effectively blocking sunlight, ultraviolet rays, and other light sources, preventing oxidation, decomposition, and other deterioration reactions caused by light exposure, thus extending the shelf life of the pharmaceuticals.
Meeting the core needs of pharmaceutical blister packaging, this product possesses excellent thermoforming performance. The key thermoforming parameters need to be controlled as follows: preheating temperature 120-160℃, preheating time 20-40s, and molding pressure 0.3-0.6MPa. Within this parameter range, it can quickly soften and set, precisely conforming to the contours of various pharmaceuticals (such as tablets, capsules, and granules), forming a tightly fitting packaging cavity, ensuring packaging airtightness and preventing the intrusion of external moisture, dust, and other impurities. At the same time, the material complies with relevant national standards for pharmaceutical packaging materials, is free of heavy metals, harmful plasticizers, and other prohibited components, and poses no migration risk when in contact with pharmaceuticals. Its safety has been rigorously tested and verified.
In addition to its core performance, this PVC rigid film also possesses excellent mechanical strength, puncture resistance, and tear resistance, effectively protecting the enclosed pharmaceuticals from external damage during production, storage, and transportation. The optimized thickness range of 200-300 μm meets the required structural strength of the packaging while also ensuring lightweight design, reducing packaging material and transportation costs, and aligning with the industry trend of lightweight pharmaceutical packaging. It is widely used in single-dose blister packaging and combination packaging of oral solid medications, making it a preferred material in the pharmaceutical packaging field due to its safety, practicality, and cost-effectiveness.
