Closure research + development
Years of research.
Engineered into the seal.
Years of research and development in plastic closures have brought together the right seal geometry, closure structure, raw-material selection and production control, supported by continuous improvement from our Quality and R&D teams. This work enables Diamond Pack to offer a no-visible-liquid-leakage guarantee below 60°C for approved applications.
Material selection
Resin, masterbatch and liner components selected for the required performance.
Process control
Molding consistency, critical dimensions and application behavior monitored in production.
Quality validation
Bottle fit, torque, seal and leakage performance checked under agreed conditions.
Performance guarantees are confirmed for the approved closure, bottle-neck finish, product, filling process, application torque, storage period and agreed validation method for each customer program.
Inline after production

Synchronized cameras
360°
Complete coverage
State-of-the-art inline inspection
Six cameras.
Every angle. Every closure.
Immediately after production, every finished closure passes through an inline inspection cell. Six synchronized cameras examine the closure around 360°, including its interior, exterior, top surface and tamper-evident features.
Inside + outside
Internal seal and liner areas, exterior profile, contamination and visible defects.
360° geometry
Threads, band, bridges, flash, deformation, short shots and overall shape.
Print inspection
Top and under-cap print presence, position and clarity wherever printing is specified.
Color verification
Color consistency and variation checked against the approved production reference.
Integrated weight control
Closure mass and weight variation monitored against the approved specification.
Automatic rejection
Any closure outside the programmed acceptance criteria is removed from the production flow.

From production to deliveryClosures in context
Designed as part of the complete bottle.
A closure performs as part of a connected system: bottle neck, application, product, label and distribution format. These concepts show that system across water, carbonated drinks, flavored beverages and multipacks.
01
Carbonated drinks
Closure color and bottle presentation developed as one visual system.
02
Still water
A clean white closure selected for a straightforward bottled-water format.
03
Juice + flavored drinks
A closure application shown in a vivid flavored-beverage format.
04
Multipack delivery
Closure, bottle, label and shrink film working together in one finished package.

Under-cap printing
Promotional campaigns
For limited-time promotions, campaign messages or approved promotional artwork can also be printed beneath the cap, creating an additional consumer touchpoint after opening.
Printing availability, artwork detail and color separation are confirmed according to the selected closure and the final production requirements.
Closure engineering
Performance in every detail.
Seal integrity
Geometry engineered for repeatable sealing across high-volume production.
Tamper evidence
A clear visual signal helps protect product confidence at first opening.
Torque control
Balanced application and removal behavior supports line efficiency and consumer ease.
Custom color
Brand-matched production options help the closure work as part of the complete package.
Quality focus
Confidence, from line to consumer.
