Press-On Twist-Off (PT) metal lids are designed for glass containers that require secure vacuum sealing, reliable product protection, and easy consumer opening. Apply the closure by pressing the lid onto the jar finish, and open it with a simple twist.
Designed for baby food, fruit purées, vegetable purées, sauces, and other heat-processed foods, PT lids provide a practical packaging solution where vacuum performance, sealing reliability, and consumer convenience are important.
Available in multiple diameters, coating systems, sealing compounds, colours, and decorative finishes, these closures can be matched with existing glass jars or developed according to specific filling processes, capping systems, and thermal processing requirements.
Key Features
Reliable Press-On Twist-Off System
Designed for efficient industrial capping while allowing consumers to easily open the container by twisting the lid. The press-on application method supports consistent closure engagement when matched with the correct jar finish and capping process.
Secure Vacuum Sealing Performance
The sealing compound creates close contact between the metal lid and the glass jar finish to support vacuum retention and help maintain product protection throughout storage.
Suitable for Baby Food Applications
Developed for products such as fruit purées, vegetable purées, baby food, sauces, and other processed foods packed in glass containers.
Food-Contact Material Options
Available with food-contact coating and sealing compound options selected according to product requirements, filling temperature, pasteurization conditions, or validated thermal processing methods.
