Product Overview

Designed specifically for soft, sticky and irregular‑shaped snack goods, this fully‑automatic bag‑in‑bag secondary packaging production line completes the whole “small‑sachet into big‑pouch” repacking workflow without heavy manual intervention.

The turn‑key line consists of Z‑type bucket elevator, 14‑head multi‑head weigher, rotary premade‑pouch packing machine and Model 300 automatic checkweigher. It covers automatic feeding, precision weighing, bag‑in‑bag filling, heat sealing, dynamic weight inspection and defective‑item rejection.

Running at up to 30 bags per minute with ±5g weighing precision, the unit adopts food‑grade 304 stainless‑steel contact surfaces and PLC intelligent control. It effectively eliminates typical pain points of manual secondary packaging: low throughput, inconsistent weight, food‑safety hazards and high material waste. Ideal for food factories pursuing large‑scale, standardized and intelligent snack production.

Industry Pain Points

• Tired of inconsistent finished‑bag weight and high reject rates caused by manual weighing & bag‑in‑bag repacking?

• Struggling with low output and labor shortages when handling high‑volume secondary packaging for mochi and sticky snacks?

• Worried about food‑safety risks from frequent human contact with ready‑to‑eat soft confectionery?

• Frustrated by fragile sticky snacks getting crushed, stuck or deformed during conventional packaging operations?

The Solution

Our Fully‑Automatic Bag‑in‑Bag Secondary Packaging Production Line delivers an all‑in‑one secondary repacking solution specially engineered for soft, sticky, irregular snacks such as mochi and glutinous rice cakes.

This modular production line integrates Z‑type bucket elevator, 14‑head multi‑head weigher, rotary premade‑pouch packing machine and Model 300 automatic checkweigher. It automates full‑cycle workflows: feeding, precision weighing, bag‑in‑bag filling, sealing, dynamic weight inspection and defective‑product rejection.

It improves your Overall Equipment Effectiveness (OEE), cuts manual dependency, lowers material waste and standardizes final‑package quality for large‑scale food manufacturing.

Core Advantages

Modular Full‑line Synchronized Automation

Feature: Four core units work in seamless linkage; Z‑type elevator, multi‑head weigher, rotary pouch packer & online checkweigher.

Advantage: Minimal human intervention across the complete bag‑in‑bag process.

Benefit: Only 1‑person line supervision, greatly reduces labor cost and human‑borne food‑contamination risks.

Consistent High‑precision Weighing Performance

Feature: 14‑head multi‑head weigher with intelligent algorithm, stable ±5g weighing tolerance.

Advantage: Accurate dynamic batching even for irregular soft glutinous snacks.

Benefit: Uniform finished‑bag weight, fewer customer complaints, meets supermarket & e‑commerce quality standards.

Stable High‑speed Continuous Production

Feature: Sustained operating speed up to 30 bags per minute, supports long‑time non‑stop running.

Advantage: Smooth operation with negligible missing or empty pouches.

Benefit: Production capacity 3‑5 times higher than manual repacking, satisfies large‑volume order delivery for food factories.

Gentle Material Handling & Closed‑loop Quality Control

Feature: Buffer‑design Z‑type bucket elevator + Model 300 automatic checkweigher with auto‑reject function.

Advantage: Avoid squeezing & sticking of fragile snacks; 100% in‑line weight inspection for every finished bag.

Benefit: Preserve complete product appearance; keep overweight / under‑weight goods off the market, raise overall product yield.
