组件规格

定义
A precision-engineered aluminum component designed to create a hermetic seal on pharmaceutical vials through crimping technology. It provides both primary containment integrity and tamper-evidence functionality in pharmaceutical packaging systems.
工作原理
The aluminum cap is placed over the vial's rubber stopper and glass neck, then mechanically crimped using specialized equipment. The crimping process deforms the aluminum skirt around the vial's flange, creating a permanent mechanical lock while maintaining compression on the rubber stopper to ensure seal integrity.
材料
Aluminum alloy 1100 or 3003typically 0.2-0.3mm thicknesswith optional epoxy or thermoplastic liner for enhanced sealing
Height
6-12mm depending on application
Diameter
13mm, 20mm, 28mm (standard pharmaceutical sizes)
Liner Type
PTFE-faced rubber, Buna-N, or silicone
Crimp Profile
Single or double fold
Surface Finish
Anodized or lacquered for corrosion resistance
标准
ISO 8362-4ISO 8871DIN 58366USP <381>

常见问题

What is the purpose of the aluminum crimp cap in pharmaceutical packaging?

It provides a hermetic seal to maintain product sterility, prevents contamination, and offers tamper-evidence to ensure patient safety.

Can aluminum crimp caps be used with different vial materials?

Yes, they are compatible with glass vials (Type I, II, III) and some polymer vials, but crimping parameters must be adjusted accordingly.

How are crimp caps removed from vials?

They require specialized decapping tools or pliers that cut through the aluminum skirt without damaging the vial or contaminating the contents.
