High-Speed Automatic Carton Sealing

Designed for manufacturers handling regular slotted cartons (RSC), the EZ SEAL Case Sealer automatically closes and seals the top and bottom of boxes, at speeds of up to 40 boxes per minute without operator intervention, delivering consistent, professional results.

Whether you’re packaging food, beverages, pharmaceuticals, cosmetics, or chemicals, EZ SEAL provides reliable performance, intelligent automation and optimal integration into existing production lines.

Why Choose the EZ SEAL Automatic Case Sealer?

Manual case sealing can become a bottleneck as production volume increases. This limits productivity and introduces inconsistency. The EZ SEAL Carton Sealer automates the entire sealing process, reducing labour requirements while improving line efficiency and packaging quality.

Maximise End-of-Line Productivity

With intelligent cadencing and automatic box handling, the EZ SEAL Case Sealer conveyor belt can handle up to 50 metres per minute. This reduces bottlenecks while maintaining consistent sealing performance. Interruptions are prevented by the integrated gate-based box spacing system, ensuring continuous production flow.

Automatic Recipe-Based Format Changes

Changing between box sizes no longer requires lengthy manual adjustments. EZ SEAL stores and recalls product ‘recipes’ directly from the HMI screen, using a servo-driven automatic format change system.

Machine operators can:

Select saved ‘recipes’ easily
Switch between production runs in seconds
Make micro-adjustments without stopping production
Maintain repeatable sealing performance

This ensures shorter changeover times and greater production flexibility for manufacturers running multiple SKUs.

Professional Box Sealing Every Time

Consistent carton presentation is essential for warehousing, shipping and retail distribution. EZ SEAL automatically closes the upper flaps and applies high-speed tape to both the top and bottom of every carton, ensuring:

Accurate tape placement
Secure carton closure
Reduced tape waste
Professional package presentation
Reliable pallet stability during transport

Its robust sealing system delivers dependable performance across a wide range of carton qualities.

Frequently Asked Questions

What is the SIAT SM44 HS Case Sealer?

The SIAT SM44 HS is a fully automatic random case sealer designed to automatically adjust to different carton sizes, fold the top carton flaps and seal the carton with pressure-sensitive adhesive tape.

Is the SIAT SM44 HS fully automatic?

Yes. The SM44 HS is a fully automatic case sealer. It automatically detects carton dimensions, adjusts to the carton, closes the four top flaps and applies tape without requiring an operator to manually adjust the machine between random carton sizes.

What does "random case sealer" mean?

A random case sealer is designed to process cartons of different dimensions without requiring manual machine adjustment between each carton. The SM44 HS automatically adjusts its sealing system to accommodate different carton sizes as they enter the machine.

Does the SM44 HS fold carton flaps automatically?

Yes. The machine incorporates an automatic four-flap folding device that closes the major and minor top flaps before sealing.

Does the SM44 HS seal the top and bottom of cartons?

Yes. The SM44 HS automatically applies adhesive tape to both the top and bottom of the carton.

How fast can the SIAT SM44 HS seal cartons?

The current SIAT datasheet specifies productivity of up to 10 cartons per minute for the SM44 HS, based on the shortest processable carton length. The larger SM446 HS is rated at up to 8 cartons per minute. Actual throughput depends on carton dimensions and the overall packaging-line configuration.

What carton sizes can the SM44 HS handle?

The standard SM44 HS configuration handles cartons from approximately 200 × 160 × 140 mm up to 600 × 500 × 500 mm (L × W × H). A low-box configuration can accommodate a minimum height of approximately 90 mm, depending on the selected leg configuration.

What carton sizes can the SM446 HS handle?

The larger SM446 HS can process cartons from approximately 300 × 160 × 140 mm up to 800 × 650 × 650 mm.

What type of cartons can the SM44 HS seal?

The machine is designed for RSC, HSC and FEFCO 0201 carton formats. SIAT specifies compatibility with B, C and E flute types.

What is the maximum carton weight?

SIAT's current datasheet specifies a carton weight range of approximately 1.5–32 kg for the SM44/SM446 HS range.

What type of tape does the SM44 HS use?

The machine can process pressure-sensitive adhesive tapes including PVC, OPP, PET and paper, depending on the taping-unit configuration. Standard machines use 50 mm K-Series taping units, with 75 mm taping units available as an option.

Can the SM44 HS be integrated into an existing packaging line?

Yes. The SM44 HS is designed for automated line integration and incorporates centring, cadencing, sensing and PLC signal exchange to support connection with upstream and downstream equipment.

Can the SM44 HS run fixed-size cartons as well as random cartons?

Yes. The machinery range can operate in fully random format, fixed format and bypass mode, providing flexibility for different production requirements.

What is the difference between the SM44 HS and the Nastro-SB R?

The Nastro-SB R is a semi-automatic random case sealer, while the SM44 HS is a fully automatic random case sealer. The SM44 HS also automatically folds the four top carton flaps, making it suitable for a higher level of packaging-line automation.

What is the difference between the SM44 HS and SM44 HD?

Both are automatic random case sealers. The SM44 HS is the higher-performance version, using brushless motor control for the top taping unit and a carton-height detection system.

Is the SM44 HS suitable for e-commerce?

Yes. The random-format capability and automatic adjustment make the SM44 HS well suited to applications such as e-commerce and logistics, where carton sizes can vary significantly.

Can Packserv help integrate the SM44 HS?

Yes. Packserv can assess carton dimensions, production volumes and existing equipment to determine how the SIAT SM44 HS could be incorporated into an automated packaging line.
