CHOOSE BY SEALING METHOD

Which Sealing Technology Fits Your Package?

Different packaging materials require the right combination of heat, pressure, sealing time and closure control.
01

Heat Sealing

Uses controlled heat and pressure to seal thermoplastic films, bags, pouches and trays.

02

Continuous Band Sealing

Provides continuous and efficient sealing for high-volume bag and pouch production.

03

Induction Sealing

Creates a foil seal inside bottle caps for leak prevention and tamper evidence.

04

Ultrasonic Sealing

Produces clean, controlled seals for plastic and laminated tubes with minimal external heat.

05

Can Seaming

Mechanically joins the can body and lid to create a secure and consistent double seam.

06

Vacuum Sealing

Removes air before closing the package to protect products and extend shelf life.

07

Film & Tray Sealing

Applies roll film or precut lids to cups and trays using controlled heat and pressure.

08

Carton Tape Sealing

Automatically folds and tapes cartons for consistent end-of-line packaging.

MACHINE SELECTION GUIDE

How to Choose the Right Sealing Machine

The correct sealing machine depends on your package, sealing material, required seal performance and production capacity.
01

Package Format & Material

Identify whether you are sealing bags, bottles, cans, cups, tubes, trays or cartons, together with the package material and dimensions.

02

Sealing Method

Match the package with the correct technology, such as heat, induction, ultrasonic, vacuum or can seaming.

03

Seal Quality Requirements

Consider leak resistance, tamper evidence, shelf life, appearance and the required seal strength.

04

Production Capacity

Determine your target output and whether you need a manual, semi-automatic or fully automatic sealing system.

SEALING TECHNOLOGY GUIDE

Choose by Sealing Technology

Compare common sealing methods and select the technology that best matches your packaging material, product and production requirements.
01

FILM & PLASTIC BAGS

Heat Sealing

Uses controlled heat and pressure to create a reliable seal on thermoplastic films, pouches and bags.

02

BOTTLES & CONTAINERS

Induction Sealing

Creates a tamper-evident foil seal inside caps for improved leak protection and product freshness.

03

DELICATE MATERIALS

Ultrasonic Sealing

Uses high-frequency vibration for precise, clean sealing with minimal heat exposure to the package.

04

FOOD & PERISHABLES

Vacuum Sealing

Removes air before sealing to help extend shelf life, reduce oxidation and protect freshness.

05

CONTINUOUS PRODUCTION

Continuous Band Sealing

Provides fast, consistent seals for high-volume bag and pouch production with continuous conveying.

06

LOW TO MEDIUM OUTPUT

Impulse Sealing

Applies heat only during the sealing cycle, making it efficient for intermittent bag-sealing tasks.

07

METAL CANS

Can Seaming

Mechanically joins the can body and lid to form a secure, durable and leak-resistant double seam.

08

CUPS & TRAYS

Tray & Cup Sealing

Heat-seals lidding film onto preformed cups or trays for food, beverage and ready-meal packaging.

SEALING MACHINE FAQ

Frequently Asked Questions

Answers to common questions about sealing technologies, package compatibility, machine selection and production-line integration.
1. How do I choose the right sealing machine?

The correct machine depends on your package type, material, dimensions, product characteristics, sealing requirements and target output. Send us package photos, dimensions and samples so our engineers can recommend the appropriate sealing method and machine configuration.

2. Which sealing technology is suitable for my package?

Heat and impulse sealing are commonly used for thermoplastic bags and films. Induction sealing is suitable for foil-lined bottle closures, vacuum sealing for products requiring reduced air exposure, and can seaming for metal cans. Cup and tray sealing is used with preformed containers and lidding film.

3. Can one machine seal different package sizes?

Many sealing machines can handle multiple sizes through adjustable guides, sealing parameters or changeable molds and fixtures. The available size range and changeover method depend on the package format and machine model.

4. Can you test my packages before production?

Yes. We recommend sending representative packages, sealing materials and product information for testing. Sample testing helps confirm compatibility, sealing temperature, pressure, speed and finished seal quality before shipment.

5. What production speed can a sealing machine achieve?

Output varies according to the sealing method, package size, material, seal width, heating or cooling time and automation level. Provide your required units per minute or per hour so we can calculate a suitable machine configuration.

6. Can the sealing machine be integrated into an automatic line?

Yes. ZONESUN sealing machines can be integrated with container feeding, filling, capping, labeling, coding, inspection, conveying and end-of-line packaging equipment to create a coordinated production line.

7. Can you customize the machine for special packages?

Yes. Customization may include sealing dimensions, molds, fixtures, conveyor height, electrical standards, controls, safety guarding and communication with upstream or downstream equipment.

8. What information is needed for a recommendation?

Please provide the package type and material, dimensions, sealing material, product details, required seal performance, target output, available power supply and whether the machine will operate independently or as part of a complete line.
