PVC magani (Polyvinyl chloride) da PVDC (Polyvinylideene chloride) Dukansu kayan da aka saba amfani da su ne a cikin masana'antar harhada magunguna don marufi. Yayin da suke da wasu kamanceceniya, akwai manyan bambance-bambance tsakanin su biyun:

Kayan haɗin kai:

PVC magani: Shi polymer thermoplastic wanda aka haɗa da farko na vinyl chloride monomers. An haɗa ƙarin abubuwan ƙara don haɓaka kaddarorin sa kamar sassauci, tasiri juriya, da kwanciyar hankali.
Farashin PVDC: Shi polymer thermoplastic wanda aka haɗa da farko na vinylidene chloride monomers. PVDC copolymer ne na vinylidene chloride da sauran monomers, yawanci yana ɗauke da ƙaramin kaso na vinyl chloride.
Katangar katanga:

PVC magani: PVC yana ba da kaddarorin shinge masu matsakaici akan danshi, oxygen, da sauran gas. Yana ba da isasshiyar kariya ga yawancin samfuran magunguna amma maiyuwa baya yin tasiri sosai don ƙirar ƙima ko ɗanɗano..
Farashin PVDC: An san PVDC don kyawawan kaddarorin shinge. Yana ba da shinge na musamman ga danshi, oxygen, haske, da sauran gas. Fina-finai masu rufin PVDC ko laminates suna ba da kariya mafi kyau don tabbatar da kwanciyar hankali da tsawon rayuwar samfuran magunguna..
Ra'ayi:

PVC magani: PVC gabaɗaya a bayyane yake, ba da damar dubawa na gani na abubuwan da ke cikin marufi.
Farashin PVDC: Fina-finan PVDC ko sutura suna da haske sosai, samar da kyakkyawan haske da ganuwa na samfur ɗin da aka haɗa.
Juriya na sinadarai:

PVC magani: PVC yana da juriya ga yawancin sinadarai na gama gari kuma yana da juriya mai kyau ga mai, mai, da masu shan giya. Duk da haka, maiyuwa bazai dace da wasu kaushi ko sinadarai masu tsauri ba.
Farashin PVDC: PVDC yana nuna juriya na sinadarai kuma yana dacewa da mafi girman kewayon kaushi da sinadarai idan aka kwatanta da PVC..
Kwanciyar hankali:

PVC magani: PVC yana da kyakkyawan kwanciyar hankali na thermal kuma yana iya jure yanayin zafi mai faɗi yayin aiki da ajiya.
Farashin PVDC: PVDC yana da kyakkyawan kwanciyar hankali na thermal, ƙyale shi don kula da kaddarorinsa ko da a cikin yanayin zafi mai zafi.
Abubuwan Hulɗa:

PVC magani: An yarda da PVC ko'ina kuma an yarda da shi don aikace-aikacen marufi na magunguna. Duk da haka, an taso da damuwa game da yuwuwar leaching na robobi (misali, DEHP) daga PVC, musamman a wasu aikace-aikacen likita.
Farashin PVDC: Ana ɗaukar PVDC gabaɗaya a matsayin abu mai aminci da inganci don marufi na magunguna. Ana amfani da shi sau da yawa a aikace-aikace inda ake buƙatar ingantattun kaddarorin shinge.
Yana da mahimmanci a lura cewa ƙayyadaddun kaddarorin da ƙirar PVC na magani da PVDC na iya bambanta dangane da masana'anta da aikace-aikacen da aka yi niyya.. Jagororin tsari da buƙatu na iya ba da izini zaɓi na kayan marufi na magunguna.
