learn moreE-commerce fulfillment teams face relentless pressure to cut shipping costs, reduce labor and protect products in transit. Rennco’s e-commerce packaging machines address all three by automating the bagging process, right-sizing every package to minimize DIM weight charges and producing consistent, professional mailers at production speed.
All Rennco vertical bagging systems form bags on demand from centerfolded roll stock film, eliminating pre-made bag inventory and the oversized packaging that drives up carrier costs.
Whether you’re running a high-volume 3PL operation, a growing DTC brand or a subscription fulfillment center, Rennco has a purpose-built e-commerce packaging solution to fit your operation and your budget.

The ProCommerce is Rennco’s most versatile e-commerce auto-bagging machine, built for operations shipping fragile or damage-sensitive products. It produces right-sized bubble mailers on demand, eliminating pre-made mailer inventories and the DIM weight overages that come with them.
Video Summary: The ProCommerce forms a custom-sized bubble mailer around each product in a single automated cycle: the operator loads the item, the machine forms and seals the bag and the finished mailer is ready to label and send.
The 301 e-commerce bagger is Rennco’s proven semi-automatic e-commerce bagger for mixed-product fulfillment operations. It forms “right-sized” poly mailers from centerfolded roll stock, replacing boxes, cutting fill material and reducing excess packaging overall.
Video Summary: The operator loads a single order, and the 301 e-commerce bagging system forms a right-sized poly mailer around the contents, applies a shipping label and outputs a finished package ready for carrier pickup.
The EZ20 is Rennco’s most accessible e-commerce packaging machine, offering an all-electric, compact and plug-and-play design. No compressed air required. It runs on a standard 110V outlet and fits comfortably in space-constrained fulfillment environments where every square foot counts.
Rennco e-commerce bagging systems are widely used across:
The ProCommerce runs both bubble mailing film and opaque poly on the same machine, making it the stronger choice for operations shipping fragile goods alongside soft goods. The 301 runs opaque poly only, making it a more cost-focused option for operations that don’t need bubble cushioning.
Yes, the 301 model is specifically designed for bagger/labeler integration, handling bag forming and label application in a single cycle. The EZ20 also accommodates optional printers and labelers.
Carriers charge based on Dimensional Weight (DIM), calculated from package volume. Oversized pre-made bags inflate DIM on every shipment. Rennco systems form bags to fit each order, reducing volume and DIM charges, often saving 50%+ on consumables versus pre-made bag programs.
Manual packing is a multi-step, labor-intensive process. Rennco systems consolidate bag forming, sealing and labeling into a single automated cycle, cutting touches per package and enabling one operator to handle what would otherwise take an entire team.
