Secondary Packaging Systems for Bagged Products
From Primary Pack to Pallet — Where Secondary Packaging Fits
Secondary packaging groups individually sealed primary bags into transport‑ready units — cartons, larger outer bags, or shrink‑wrapped bundles. It protects your product during shipping, simplifies handling, and prepares items for retail or wholesale display. Whether you pack vacuum‑packed rice bricks or pillow‑packed coffee beans, the right secondary packaging system directly improves logistics costs and brand presentation.

Three Ways to Group Your Bags — Automation Ready
Automatic Carton Packing
Pack bags into corrugated cartons — ideal for rice, export foods, and distribution centers. System erects, loads, and seals automatically.
Configurations: 4‑pack, 5‑pack, custom counts

Bag‑in‑Bag Overwrapping
Load several small bags into one larger outer bag and seal — lighter than cartons, perfect for retail multi‑packs.
Groups: 4×5kg, 5×2.5kg, 10×1kg

Shrink Wrapping
Stack bags tightly and wrap in film for stable transport and storage. No carton needed — reduce consumable cost.
Usage: Directly from case packer stacking function, or manual feed.

Not every product needs a carton; not every bag is ready for film‑only wrapping. Here’s a straightforward look at how they compare.
| Feature | Carton Packing | Bag‑in‑Bag | Shrink Wrapping |
|---|---|---|---|
| Product Protection | ★★★★★ | ★★★★☆ | ★★★☆☆ |
| Material Cost | Medium | Low | Low |
| Retail Shelf Ready | Yes | Yes (multi‑pack) | Limited |
| Stackable on Pallet | Excellent | Good | Good |
| Typical Load | 4–10 bags/carton | 4–10 packs/bag | 8–20 bags/bundle |
The Automatic Carton Packing System — Erect, Load, Seal
From flat cardboard to sealed case, our carton packing system integrates a carton erector, a servo‑driven case packer (ZXJ‑2800 or ZXJ‑1400), and a case sealer — all working in sequence without manual intervention.
Carton Erector
Takes flat corrugated sheets, folds them, and positions the open carton for filling.
ZXJ‑2800 / ZXJ‑1400 Case Packer
Arranges bags by preset count (4,5, etc.), loads them gently, and stacks for shrink wrap when needed.
Case Sealer
Folds top flaps and applies adhesive tape — clean, secure seal ready for palletizing.
Spotlight: ZXJ‑2800 High‑Speed Case Packer
Speed: 2,400–2,800 bags/hour | Power: 10 kW | Air: 133 L/min
Fully servo‑driven “pre‑arrangement then packing” design minimizes idle time. One‑click product changeover, enclosed safety guarding, and intelligent fault diagnosis built‑in.

Frequently Asked Questions
What is secondary packaging?
The process of grouping sealed primary bags into cartons, outer bags, or shrink bundles for transport and sale.
How fast is the ZXJ‑2800 case packer?
2,400–2,800 bags per hour, depending on bag size and carton pattern.
Can I pack 4 or 5 bags into one carton?
Yes. Both ZXJ‑2800 and ZXJ‑1400 support adjustable counts, switchable via the touchscreen.
What is bag‑in‑bag packaging?
It packs multiple small bags into a larger outer bag. Our ZDJ‑1800 is built for 5–10kg total weight.
Can the carton packer stack bags for shrink wrapping instead?
Yes, the stacking function can output neat bag stacks directly to a shrink wrap machine, bypassing the carton.
Which industries use these systems?
Rice mills, grain processors, seed plants, feed factories, and dry food packagers are the main users.
Can EWINALL supply a complete end‑of‑line solution?
Absolutely. We design integrated lines from weighing to palletizing, with a single point of responsibility.
