Description
Give your jars a clean, finished look with this black dome cap. It has a 70-400 neck finish and a pressure sensitive (PS) liner that seals against the container rim when the cap is tightened, so there’s no induction sealer or extra equipment needed. The raised dome profile adds a premium look to the shelf, and the black finish goes with almost any label design.
Key Features
- 70-400 neck finish: fits standard 70mm jars and bottles with a 400 thread finish
- Pressure sensitive liner: bonds to the container rim under application torque for a tamper-evident seal that helps keep products fresh
- Dome top profile: a sleek, rounded silhouette that sets it apart from standard flat caps
- Black plastic construction: durable, lightweight, and resistant to cracking
- Easy to apply: hand-tighten or use capping equipment, with no heat or special tools required
Ideal For
- Cosmetics and skincare: creams, balms, scrubs, and butters
- Wellness products
- Dry foods, spices, and supplements
- Candle accessories, bath salts, and home goods
Compatibility Note: Check that your container has a 70-400 neck finish before ordering. PS liners work best with dry or thick products. For liquids or oils, ask our team about induction or foam liner options.
