Indlela Yokukhetha i-Glassine Yokusetshenziswa Kwamalebula Ezokwelapha
Kwadalwa ngo 09.01
Selecting the right glassine for medical label applications is a critical process that balances material performance, regulatory compliance, and manufacturing efficiency. Here is a comprehensive guide on how to make the right selection.
Executive Summary: Why Glassine is Chosen
Glassine is a smooth, glossy, and air-resistant super-calendered paper. Its primary advantages for medical labels are:
- High Purity & Inertness: Chemically neutral, it doesn't interact with medications or medical devices.
- Excellent Die-Cutting: Cuts cleanly without dusting, crucial for complex label shapes.
- Moisture & Grease Resistance: Naturally resistant to oils and fats, protecting the adhesive.
- Deadfold & Stability: Holds its crease and lies flat, important for application onto syringes, vials, and equipment.
- Printability: B提供了一个出色的表面，用于高质量打印和可变信息。
Step-by-Step Selection Criteria
1. Regulerings- en Nalevingsvereistes (Die Eerste Prioriteit)
Lokhu akusiyo into engaxoxwa ngayo. Imathiriyali kumele ihlangabezane nezindinganiso eziqinile.
- FDA 21 CFR Part 175.105 / 175.125: Le fa le faamaonia o le adhesive ma le fa'avaa e saogalemu mo le feso'ota'iga i mea'ai i le auala e le fa'atekinolosi, o se fa'avae masani mo le afifiina o le vaila'au. Fa'amautinoa e le tagata e te fa'atauina mai e ofoina mai se Tusi Fa'amaonia (LOG) po'o se Fa'amaoniga o le Usufono mo nei faiga.
- USP <661> / USP <661.1> (US Pharmacopeia): Lezi zihloko zichaza izinqubo zokuhlola ezinhlelweni zokupakisha zeplastiki kanye nezinto ezakhiwe ngazo. Nakuba ngokwesiko zisetshenziswa kuma-plastics, imigaqo yokukhishwa nokukhipha isetshenziswa kakhulu ezindaweni ezisekelwe ephepheni njenge-glassine. Qinisekisa nomphakeli wakho ukuthi umkhiqizo wabo uhlolwe futhi uhambisana nomoya walezi zidingo.
- REACH / RoHS: Qinisekisa ukuthi izinto azinazo izinto ezikhathazayo kakhulu (SVHC) nezinto eziyingozi ezivinjelwe, okubaluleke kakhulu emakethe ye-EU.
- Supplier Documentation: Your supplier must provide full traceability and Certificates of Analysis (CoA) for each batch to ensure consistency and compliance.
2. Iimpawu Zokusebenza Ezisebenzayo
Hlola i-glassine ngokusekelwe ezidingweni ezithile zokusebenza.
- Basis Weight/Thickness:
Ngokwenziwa ngamagramu ngekhamera eyisikwele (gsm) noma ngamaphawundi nge-ream (lbs).
Standard: 60-90 gsm is common.
Thinner (e.g., 60 gsm): Bietet hohe Flexibilität, passt gut zu kleinen Durchmessern (z.B. Spritzenzylindern) und ist kosteneffektiv.
Thicker (e.g., 90 gsm): Provides more rigidity, better "pop-up" in automated applicators, and a premium feel. Better for large device labels.
- Caliper (Thickness): Measured in mils or microns. A consistent caliper is crucial for smooth dispensing and die-cutting.
- Moisture Vapor Transmission Rate (MVTR):
Ngesikhathi i-glassine iyisithiyo esihle, ezinye izidakamizwa ezinamandla aphezulu noma amadivayisi abucayi angase adinge izinga elengeziwe lokuvikela.
Ask your supplier for MVTR data. If a better barrier is needed, consider clay-coated glassine or a film-based liner (e.g., PET polyester).
- Lay Flat & Curl: I-liner kumele ilele kahle ngokuphelele emgqonyeni ukuze ivimbele ukujamming emshinini wokuphrinta ophakeme kanye nezinsiza zokuhambisa. Ukungena komswakama kungathinta lokhu, ngakho xoxa ngezimo zemvelo nomphakeli wakho.
- Release Level: Lesi kezi iqukethe amandla adingekayo ukuze kususwe ilebula kwi-glassine liner. Lokhu kulawulwa ukumboza kwe-silicone.
Standard Release: The most common choice.
Low Release (Easy Release): Used for very aggressive permanent adhesives or very fragile labels to prevent tearing or "flagging."
High Release (Tight Release): Used for less aggressive adhesives to ensure the labels don't fall off the liner during conversion and shipping.

3. Conversion and Printing Considerations
How will the material behave during the label manufacturing process?
- Die-Cutting Performance: This is a key strength of glassine. It must die-cut cleanly (to allow for easy matrix stripping) without fracturing or "nickering," which creates paper dust that can contaminate sterile environments.
- Printability:
Surface Energy: Should be >38 dynes/cm to ensure good ink adhesion. Most quality glassine liners are treated to meet this.
Porositeit: Beïnvloedt de inktabsorptie en droogtijd. Bespreek met uw drukker om het inkt systeem af te stemmen (bijv. UV flexo, op waterbasis).
- Matrix Removal: I "waste" material ebesikwe emaphepheni kumele ikhiphe kahle futhi ithembekile ngezinga eliphezulu ngaphandle kokuphuka.
4. Ukusebenzisa Isimo Sezinhlelo
Where will the final label be applied and stored?
- Temperature Extremes: Will the labeled product be autoclaved, frozen (e.g., -80°C storage), or exposed to high heat? Ensure the adhesive is matched to this, and confirm the glassine's performance won't degrade (e.g., become brittle when frozen).
- Chemikalienexposition: Wird das Etikett Alkohol-Tupfer, Lösungsmittel oder Sterilisationsmittel (z. B. VHP, ETO, Gammastrahlung) ausgesetzt? Während der Etikettenoberstoff und der Kleber die primären Barrieren sind, darf der Träger nicht abgebaut werden oder während der Anwendung schwer zu entfernen sein.
- Uhlelo Lokufaka:
- Manual Application: Less critical for liner performance.
- High-Speed Automated Application: I-liner kumele ibe ne-caliper ehambisanayo kanye ne-geometry ye-roll ukuze iqhube kahle kuma-automatic label applicators (ALAs). Kumele futhi ikhulule ilebula ngendlela elindelekile futhi ehlanzekile.
Common Types of Glassine for Medical Use
Type | Tlhaloso | Best For |
Standard Glassine | Ihlobo elivamile kakhulu, mhlophe yemvelo, i-super-calendered. | Izincwadi zemithi ezijwayelekile, izincwadi ze-vial, izincwadi zamadivayisi. |
Clay-Coated Glassine | Het 'n dun laag klei op die oppervlak, wat 'n selfs gladder, meer ondoordringbare versperring skep. | Hogere barriervereisten, superieure afdrukkwaliteit en inktvastheid. |
PEGylated (Polycoated) Glassine | Coated with a polyethylene (PEG) layer. Provides a significantly higher moisture and chemical barrier. | Izicelo ezidinga umkhawulo ophakeme kakhulu ku-liner esekelwe ephepheni, ngokuvamile zisetshenziswa kumalebula e-freezer-grade. |
Thermal Glassine | A spesifieke graad ontwerp om die hitte van termiese oordragdrukkers te weerstaan sonder om gasse vry te stel wat drukkoppe kan verstop. | Labels that require variable information (barcodes, serialization) printed via thermal transfer. |
Isigcawu Sokwenza Izinqumo

Enhanced barrier for sensitive drugs? → Clay-Coated or PEGylated Glassine.
Extreme barrier or chemical exposure? → Consider a Film Liner (PET).
3. Thola Indlela Yokufaka:
High-speed automated application? → Prioritize consistent caliper and lay-flat
Manual application? → Fokus op koste en gebruiksgemak.
4. Bheka Ukuphrinta:

High-quality graphics? → Clay-Coated Glassine offers superior printability.
5. Prototype and Test: Lezi yisinyathelo esibaluleke kakhulu. Sebenzisa umphakathi wakho wokuguqula amalebula ukwenza izivivinyo. Test:
Die-cutting on your specific label shape.
Dispensing on your automatic applicators.
Label aansoek en hegte onder werklike toestande (sterilisasie, vries, ens.).
Partner with Experts
Ultimately, the best way to select the right glassine is to partner closely with two entities:
1. Uw Etiketomsetter: Hulle het die tegniese kundigheid om materiale aan te beveel op grond van jou druk, stans, en toepassingsapparatuur.
2. I-Phapha Umkhiqizi (isb., Xianhe, Heming, Mondi, Sappi, Expera, Nordic Paper): Bangahlinzeka ngama-technical data sheets, imibhalo yokuhambisana, nezincwadi zokuncoma ezisekelwe endaweni yokusetshenziswa.
Ngokuhlola lezi zinto ngendlela ehlelekile—uqala ngokuhambisana bese uhamba phambili kokusebenza, ukuguqulwa, nokusebenza—ungakhetha ngokwethembeka i-glassine liner efaneleka kakhulu ohlelweni lwakho lokufaka amalebula wezokwelapha.
