Kanggo kemasan farmasi aluminium foil, kualitas prodhuk umumé dibayangke ing kekuatan segel panas prodhuk. Mulane, sawetara faktor sing mengaruhi kekuatan penyegelan panas saka tas aluminium foil kanggo obat-obatan wis dadi kunci kanggo ningkatake kualitas kemasan produk..
1. Bahan mentahan lan tambahan
Aluminium foil asli minangka pembawa lapisan adesif, lan kualitas nduweni pengaruh gedhe ing kekuatan segel panas prodhuk.
On the one hand, reregetan lenga ing lumahing aluminium foil asli bakal weaken adhesion antarane adhesive lan asli aluminium foil. If the surface of the original aluminum foil has oil stains and the surface tension is lower than 31×10-3μm, iku angel kanggo entuk kekuatan segel panas becik. Ing tangan liyane, the metal composition and insufficient surface brightness of the original aluminum foil affect the strength of the heat seal, and the quality of the original aluminum foil must be strictly controlled.
2. In terms of adhesives
Adhesive minangka zat khusus sing ngemot pelarut. Iki dilapisi ing sisih peteng (utawa sisih Gamelan) saka aluminium foil asli ing kahanan proses tartamtu, lan garing ing trowongan pangatusan kanggo mbentuk lapisan adesif, which plays a decisive role in the heat seal strength of the product
Ing saiki, most domestic manufacturers use imported raw materials to prepare adhesives, and the products can achieve higher heat sealing strength. Nanging, rega bahan baku impor larang banget. Supaya entuk bathi sing dhuwur kanggo produk kasebut, sawetara manufaktur kanthi kemampuan riset ilmiah sing kuwat wis miwiti riset lan ngembangake bahan mentah domestik sing padha.
3. Proses produksi
Ing kontrol paramèter proses tartamtu, adesif wis ditutupi ing lumahing aluminium foil asli kanggo mbentuk film, and the quality of the finished composite film will directly affect the heat seal strength of the product. Antarane paramèter sing luwih penting kalebu kacepetan lapisan, suhu segmented saka trowongan pangatusan, wangun, ambane, nomer baris, lan posisi lan amba saka agul-agul roller nutupi.
Kacepetan lapisan nemtokake wektu pangatusan lapisan ing trowongan pangatusan. Yen kacepetan lapisan cepet banget lan suhu terowongan pangatusan dhuwur banget, the solvent on the surface of the coating film will evaporate too quickly, resulting in residual solvent in the film, lan film lapisan ora bakal cukup garing, lan bakal angel kanggo mbentuk garing, lapisan adhesive kuwat lan kuwat. Affect the heat seal strength of the product and cause adhesion between product layers.
Bentuk anilox, ambane, nomer garis lan posisi lan amba saka lading dhokter nemtokake kekandelan lan uniformity saka film nutupi. Yen pilihan utawa pangaturan ora cocog, the adhesive will not be evenly coated on the surface of the original aluminum foil, nyebabake pembentukan film sing ora rata, the heat sealing effect of the product will not be good, lan kekuatan uga bakal kena pengaruh.
4. Suhu sealing panas
Suhu penyegelan panas minangka faktor penting sing mengaruhi kekuatan segel panas. Yen suhu kurang banget, lapisan adhesive ora bisa panas-sealed karo film PVC uga, lan jaminan antarane lapisan adhesive lan film PVC ora kuwat. Yen suhu dhuwur banget, tamba bakal kena pengaruh. Mulane, suhu sealing panas cukup biasane antarane 150 ° C lan 160 ° C.
5. Tekanan sealing panas
Kanggo entuk kekuatan sealing panas becik, tekanan sealing panas tartamtu kudu disetel. Yen tekanan ora cukup, ora mung lapisan adesif produk lan film PVC ora bisa diikat kanthi lengkap lan disegel panas, but also air bubbles can be left between the two, and a good heat-sealing effect cannot be achieved. Mulane, the national standard stipulates that the heat sealing pressure is 0.2mPa.
6. Wektu sealing panas
Wektu panas-sealing uga bakal mengaruhi kekuatan panas-sealing produk. Ing kahanan normal, ing suhu sealing panas padha lan meksa, wektu sealing panas maneh bisa nggawe bagean panas-nyegel bakal nutup luwih kuwat lan sampurna, lan bisa luwih entuk kekuatan panas-sealing samesthine. Nanging, the technological conditions of modern high-speed pharmaceutical packaging machines cannot provide a long time for heat sealing. Yen wektu sealing panas banget cendhak, sealing panas antarane lapisan adhesive lan film PVC bakal ora cukup. Kanggo alasan iki, standar nasional stipulates sing wektu sealing panas ilmiah 1s.
