FoldSerter

It’s your brand. Show it off. Now in full color.

Retailers have the freedom to develop any graphics or personalization, each unique to each customer, and incorporate their documentation into the order database, tied to the unique order ID or LPN. eCommerce and fulfillment companies can now, in an automated way, add on-demand colorful documents to their orders, in addition, to pack slip.

Automation of the packing process can deliver one of the greatest investment paybacks, with measurable impacts across a range of critical factors affecting warehouse operators today.

Improve Picking Speed (Fewer Lines Per Order)

If pickers and packers are currently dealing with the paperwork, by automating them, this means one less line per order. Speeding up your pickers dramatically.

Faster Order Processing

Scaling up with weekly rush days and annual holiday peaks is no longer as challenging. Automation also gives you room to grow without multiplying labor.

Personalized to Every Order

Automating documents gives your marketing team the freedom to add a variety of items such as personal gift notes, coupons, loyalty information, as well as receipts.

Achieve “The Perfect Order”

Save the documents until the end. Scan verification and parity checking guarantees accuracy. Removal of human error can increase customer satisfaction and prevent returns.

Reduce Repetitive Manual Labor

The FoldSerter automates document insertion for every order, reducing manual labor and boosting efficiency. Save time, cut costs, and streamline your packing process.

Accuracy Verification Built-In

The FoldSerter uses scan verification to ensure each document matches the box’s LPN. If a document lacks a barcode, StreamTech’s WCS software can automatically generate and apply one for seamless tracking.

How FoldSerter Works

FoldSerter™ identifies the package, prints and folds the collateral and automatically verifies the packslip against the carton in real-time to achieve the ‘perfect order.’ It provides high throughput, multi-page capability, with less complexity than alternative systems. Patented (US 10,822,131 B2).

As each package enters the FoldSerter station, it’s automatically scanned and identified to match it with the correct packing documentation.

The system prints the required plain paper packing slip, invoice, or other collateral on demand, ensuring up-to-date and accurate documentation.

The printed documents are automatically folder—typically in a C-fold or Z-fold—making them compact and ready for insert.

The system performs a 100% verification check to ensure the printed documents match the correct package, eliminating packing errors.

Once verified, the folded document is automatically inserted into the carton at the right stage in the packing process.

The completed package moves down the line, ready for the next step in your pack process.

From speed to accuracy to labor savings, our automation solutions deliver measurable results that transform warehouse performance.
