pharmaceutical aluminum crimp cap is manufactured through a sequence of aluminum sheet stamping, drawing, trimming and lacquering processes, consisting of bromobutyl or chlorobutyl rubber stopper as the primary sealing component.
Quality certification: ISO 15378, EU GMP, USP / EP compliant, DMF filing available upon request.
Pharmaceutical crimp cap can be crimped onto vial necks at room temperature using standard crimping tools
is widely used for sealing injectable drugs, lyophilized powders, vaccines, infusion solutions and diagnostic reagents.
It is broadly applied across the pharmaceutical, biotechnology, veterinary, and medical device industries as the primary closure system for glass and plastic vials.
In certain applications, installation is facilitated by spring-like action, gaskets or self-sealing products with requirement of high thermal insulation and mechanical strength.
In certain applications, the rubber stopper enables needle penetration after tear off the aluminum cap, while maintaining sterile integrity, meeting requirements for high sealing performance, chemical resistance and compliance with international pharmacopoeia standards.

Pharmaceutical Vial Aluminum Pull-Ring Cap
Aluminum pull-ring cap comes in the form of crimp-sealed aluminum closure with an integrated pull ring.
The cap consists of a high-purity aluminum ferrule crimped securely over the vial neck, combined with a precision-formed pull ring tab bonded to the top surface. The ring is designed for clean, controlled removal — simply pull the ring upward and tear along the scored line to detach the aluminum top, exposing the rubber stopper beneath for immediate needle access, without the need for any tools or equipment.
Application
Pharmaceutical vial aluminum pull-ring cap has a wide range of following applications: To seal injectable drug vials containing antibiotics, vaccines, insulin, and other sterile liquid or lyophilized formulations; To provide tamper-evident closure for diagnostic reagent vials and veterinary injectable products; To be used in hospital and clinical settings where rapid, one-hand opening is required for emergency or high-frequency injection procedures; To meet aseptic packaging requirements in pharmaceutical manufacturing lines operating under GMP and USP/EP standards.
Perforated aluminum cap
Perforated aluminum cap (also called center-hole aluminum cap or open-hole crimp cap)
it is a kind of pharmaceutical packaging material.
It is circular in shape with a central through-hole in the middle, allowing needle penetration directly through the rubber stopper without removing the cap. It is mainly used in pharmaceutical packaging materials industry, sealing injection vials, biotechnology industry, veterinary medicine, diagnostic reagents, lyophilized drug products, and other medical and healthcare fields, and it is a very common injectable drug packaging component. According to the type, it can have plain aluminum cap, colored lacquered cap, and printed cap, and so on. The perforated aluminum cap for injectable vials is a kind of high-performance pharmaceutical packaging product with excellent sealing integrity, chemical resistance, and compatibility with standard crimping and decapping equipment, fully compliant with USP, EP, and GMP requirements.
Bridge-type aluminum cap
Bridge-type aluminum cap (also called bridge crimp cap).
it is a specially designed sealing component for injectable vials, with an integrated "bridge" structure connecting the tear-off tab to the aluminum shell. It is a tamper-evident cap with high sealing integrity and smooth, clean opening performance. It is used widely as a closure solution for injectable drug vials, lyophilized powder vials, veterinary medicine bottles, and diagnostic reagent containers. The bridge structure allows the cap to be torn open cleanly and precisely without tools, while remaining completely intact and tamper-evident before first use.

Tear-off aluminum cap
Tear-off aluminum cap for injection vials.
it is a specially tear-off design with arrow. It is needle-penetration free and tool-free in operation, maintaining strict hygienic standards during injectable preparation. It is used widely as a primary closure for antibiotic vials, lyophilized drug vials, vaccine bottles, veterinary injectables, , diagnostic reagent containers and health supplement closures.

Selection of raw materials for aluminum crimp cap
Aluminum foil and aluminum sheet are the primary raw materials for the production of aluminum crimp caps, sourced from high-purity aluminum ingots processed through rolling, annealing, and surface treatment. They are mainly used to produce various kinds of aluminum crimp caps, plain aluminum caps, flip-off caps, tear-off caps, and bridge-type caps as primary closure components for pharmaceutical and laboratory packaging. Widely used in the pharmaceutical industry for injectable vials, lyophilized powder vials, and infusion bottles, or formed and coated into a variety of cap types for biotechnology, veterinary medicine, diagnostics, food and beverage, cosmetics, and industrial chemical packaging.
All raw materials are selected in compliance with USP, EP, and GMP requirements to ensure full compatibility with injectable drug contact applications and international pharmaceutical packaging standards.
