100% Seal Inspection for better flexible packaging results

SealScope™ is an in-line, 100% seal inspection and process monitoring technology for flexible packages. Using sensors mounted on the sealing jaws, SealScope™ non-destructively detects product in seal, wrinkles and tapered seals. Early warnings for process drifts enable preventive machine maintenance. Leading companies in the food, pet care and other industries are using SealScope™ to improve the outgoing packaging quality, optimize the productivity and reduce the packaging cost.


WHAT IS SEALSCOPE™?

SealScope™ is a patented, in-line solution for 100% seal inspection and monitoring of your sealing process. SealScope’s main functionalities are:

  • Detection and rejection of compromised packages due to wrinkles or product in seal
  • Optimization of your packaging process for higher outgoing packaging quality and higher packaging equipment performance and availability
  • Monitoring of your sealing process and issuing alarms when exceeding user defined thresholds
  • Logging and visualization of production data

SealScope™ is compatible with almost all packaging machines producing flexible packaging types including pillow bags, flow packs and pouches and can verify up to 500 packages per minute.

Using the detection and monitoring tools of SealScope™, the outgoing number of packages with defective seals can be reduced by a factor of 10 or more (*). Additionally, the overall packaging machine effectiveness can be increased while monitoring the sealing quality.


SEALSCOPE™ LAYOUT

SealScope™ consists of one or multiple sensors, a controller cabinet with touchscreen and the intuitive SealScope™ software.


SEALSCOPE™ WORKING PRINCIPLE

SealScope™ checks every seal by measuring the sensor signal(s) during the closing of the seal bars and comparing them with a reference model.

In case the difference is higher than the user defined limit, SealScope™ will issue a rejection signal.

The reference models are automatically updated at the start of every run using correct seal profiles (base lining).

SealScope™ can use different reference models to accommodate changes in thickness, material, weight or size.



Good seal


Bad seal



SEALSCOPE™ BENEFITS

INCREASING PACKAGING QUALITY
Detection and rejection of compromised seals results in higher outgoing quality. This means longer shelf life, higher customer satisfaction and ultimately a stronger brand image.
INCREASING PACKAGING LINE PERFORMANCE AND AVAILABILITY
Often packaging machines run either too slow (to get acceptable quality) or too fast (with adverse effect on quality).
With SealScope™ you can determine the optimal machine speed where production output and package quality are maximized. Additionally, rejection of open packages will reduce downstream contamination and standstills.
END-OF-LINE AUTOMATION
SealScope™ enables safe end-of-line automation by automating the seal inspection process.

ELIMINATING MANUAL INSPECTION
SealScope™ allows the replacement of manual verification by 100% automated seal inspection.
UNIFORMIZING PRODUCTION PERFORMANCE
By comparing SealScope™ data from various operators and machines, a better overall production performance can be achieved.
OPTIMIZED MACHINE OPERATION
By verifying the bad packages, the root cause of rejection can be faster determined. This makes it easier for operators and maintenance to keep the machines in optimal operation conditions.

SEALSCOPE™ APPLICATIONS

Pouch packaging

Pouches are more and more popular and available in different types and materials. Also perfect for retort applications They are packaged on rotary or horizontal pouch packaging machines. Example applications are powder, juices, sauces Its main field of application includes loose products, granulated products or doughy products.


SealScope™ setup
Sensors are installed – eventually using brackets- on the sealing jaws of the packaging machine and measure during the closing of the sealing jaws. Every time a package is sealed, the actual measurement is compared to a reference model of correctly sealed packages. In case the deviation is higher than a user defined limit – due to product in seal, or wrinkles or folds in the seals-, SealScope™ will issue a rejection signal and the package is excluded via an ejecting system.

Typical products

Powders, pellets, vegetables, fruits, sauces, pet food, etc

Supported machine brands

The SealScope™ system is adaptable to most heat sealing packaging processes and as such independent of the machine brand. On pouch packaging machines, Engilico has e.g. installations on e.g. SN Packaging, Toyo Jidoki, LeePack, HDG, MesPack, VolPak.



Flow wrap packaging

Flow wraps also called flowpacks or HFW are suited for packaging a wide variety of products often in MAP conditions either separately or on a tray. It’s ideal for packaging single items such as sliced cheese, meat products, breads, pasta etc.

Pillow bags packaging

Pillow bags are made through VFFS packaging. Form/Fill/Seal packing machines use a single film coil to obtain a package with three weldings : two cross-weldings and one longitudinal welding. Its main field of application includes loose products, granulated products or doughy products.

SEALSCOPE™ REPORTING

  • Visualization of production data

SealScope™ logs hourly production data to visually compare performance over various operators, products and packaging lines.

  • Logging of production data

SealScope™ logs date, time, total packages, number of good/bad packages per product type.
This data is available in .txt-format for offline statistical analysis.

  • OPC / MQTT

All measurement data can be shared to the company network via OPC/MQTT connectors.
This allows big data analysis & processing to monitor the line performance.

  • Audit trail

Operator interactions with SealScope™ are logged to obtain 100% traceability.
