Aluminium foil sing digunakake ing Packaging blister obat yaiku bahan penyegel sing disegel ing lembaran plastik keras, uga dikenal minangka bahan capping, usually called Foil aluminium pharmaceutical ptp, which comes from the abbreviation of Press Through Packaging in English, meaning “Packaging by pressure”, Through a pressure means to seal the operation. PTP aluminum Foil is a word widely used in Asia. Ing Eropa, people commonly use the expression push-through Foil, which means “push-through aluminum Foil” in Chinese. But the abbreviation PTP seems to be more commonly used. This is also the reason why drug blister packaging is called PTP aluminum foil.

This push-in packaging ensures product or packages integrity in unit dose blister packaging compared to other packaging methods, as each drug product can be individually packaged, including shelf life for each individual dose. Kanthi cara iki, the drug is placed in the pit (bubble cover or blister eye) of the plastic hard sheet formed by blister, and then a piece of aluminum foil, kang dicithak dening gravure lan ditutupi karo agen protèktif lan adesif, diikat karo lembaran plastik sing atos lan disegel kanthi panas supaya obat kasebut disegel kanthi maksimal lan obat kasebut dijamin utuh..

Kemasan blister obat pisanan dikembangake dening negara-negara Eropa ing taun 1930-an. Sawise dandan bertahap lan promosi, cara iki dikenali dening liyane wong lan rauh dadi populer. Aplikasi saka jinis packaging ing China punika relatif pungkasan, lan kemasan tutup gelembung sing digunakake ing awal taun 1970-an biasane diimpor kanthi bantuan saka wilayah manca. Mengko, kanthi nambah ijol-ijolan internasional, Ing awal taun 1980-an, China berturut-turut ngenalake obat-obatan manca “PTP” aluminium foil printing lan peralatan nutupi lan teknologi saka Guangzhou, Lianyungang, lan wilayah liyane. Ing taun 1990-an, kanthi perkembangan lan kemajuan teknologi, China wis bisa mrodhuksi monochrome utawa multi-warna aluminium foil printing lan peralatan nutupi lan bisa print seri emas produk packaging obat aluminium.

Iki obat sing apik “PTP” aluminium foil non-beracun lan hambar minangka bahan sealing. Bahan baku utamane digawe saka aluminium foil 8011-H18 utawa 8011-O. Kekandelan dibutuhake antarane 0.016 lan 0.04 mm. Bahan sing digunakake kanggo pangolahan lan produksi yaiku 99% aluminium elektrolitik karo seri calendering lan liya Processing. Bisa duwe konduktivitas listrik lan shading sing apik, uga tahan kelembapan sing dhuwur, resistance gas. Umume, syarat materi banget ketat, mbutuhake kekandelan 0,02mm, kekuatan tarik 98 kPa, kekuatan pecah 90kPa, kanggo nggawe lumahing resik, lancar, ora kisut, ora karusakan indentation, ora ana potongan materi neon, ing bab iki, Henan Huawei Aluminium wis ngupayakake kesempurnaan, nguber luwih apik.

Kanthi pangembangan industri farmasi ing tahap pungkasan lan perbaikan tingkat teknis, wong lan perusahaan bakal duwe syarat sing luwih dhuwur lan luwih dhuwur babagan kualitas foil pharmaceutical, kayata nambah werna printing, syarat kualitas lumahing alus, lan dandan saka kacepetan gluing lan peralatan pewarna.
