The seal is the most critical element of many packages, acting as the primary barrier that protects the product from contamination, oxidation, and moisture. We engineer robust sealing solutions based on the optimal technology for your specific material and application—from direct heat and impulse sealing for bags to induction and ultrasonic sealing for containers and sensitive products.

A failed seal means a failed product. That's why we focus on the science of sealing: precise control of temperature, pressure, and time. For flexible packaging, we build heat sealers (both constant heat and impulse) that create strong, consistent seals on a variety of films. For tamper evidence and freshness in bottles and jars, our induction sealers use an electromagnetic field to bond a foil liner to the container rim. For delicate medical devices or applications where heat is undesirable, we integrate ultrasonic sealing technology, which uses high-frequency vibrations to create a strong, clean bond without significant heat generation

Heat Sealing: Constant Heat (hot bar), Impulse Sealing, Band Sealing
Induction Sealing: For applying foil liners to bottle/jar necks (tamper evidence)
Ultrasonic Sealing: For heat-sensitive products, medical devices, and rigid plastics
Automation: Manual sealers, semi-automatic, fully automatic in-line systems
Applications: Bag/pouch sealing, tray lidding, tube sealing, container sealing

The Package: What is being sealed (bag, tray, bottle)? Provide materials and dimensions.
The Film/Liner: What is the specification of the sealing material?
The Seal: What is the required seal width, strength, and appearance (e.g., must be peelable)?
The Environment: Are there any special requirements (e.g., vacuum, gas flush, cleanroom)?

FAQ -

Q1: What is the difference between constant heat sealing and impulse sealing?
A1: Constant heat sealers keep the sealing bars hot at all times. They are great for high-speed applications but consume more energy. Impulse sealers heat a wire or element for a very short "impulse" when the jaws close and then cool it under pressure. They are more energy-efficient and safer, and provide excellent results for materials like polyethylene.
Q2: How can I be sure my seal is strong and won't leak?
A2: The key is precise control of the three "T's": Temperature, Time, and pressure (Tonnage). Our machines use PID temperature controllers and precise timers to ensure these parameters are identical for every seal. We can also integrate seal integrity testing, like a burst test or vacuum decay test, to validate the sealing process.
Q3: What is induction sealing and why is it used?
A3: It's a non-contact process. An induction sealer generates an electromagnetic field that heats up a conductive foil liner inside a cap. The heat melts a polymer layer on the foil, which then fuses to the rim of the container. It's used to create a hermetic, tamper-evident seal that provides excellent barrier properties and leak protection.
Q4: When should I choose ultrasonic sealing over heat sealing?
A4: Choose ultrasonic when heat is a problem. This includes sealing thermally sensitive products (like electronics or chocolate), preventing damage to the product inside, or when you need to seal through contaminants (e.g., a little powder on the seal area). It also creates a very strong, clean bond on rigid plastics.
Q5: Can your machines work with recyclable or compostable packaging materials?
A5: Yes. However, these materials often have a much narrower "sealing window" (the range of correct temperature and time) than traditional plastics. This makes precise process control even more critical. Our servo-driven and PID-controlled machines are specifically designed to handle these sensitive materials by maintaining extremely stable sealing parameters.
