How to Choose a Shrink Packaging Machine
A complete guide to selecting the right shrink packaging machine for your production needs — from speed requirements to film types and machine configurations.
Quick Answer
Choose an L-type sealer (ZF-A series, 40 bags/min) for boxed products and multi-packaging with strong vertical seals. Choose a reciprocating sealer (ZF-GS series, 80-120 packs/min) for high-volume flat products like cards, books, and food items. Both require a shrink tunnel (ZF-S series) for final film shrinking. For complete lines, add case erectors, labeling machines, and palletizing robots.
Determine Your Speed Requirement
The first factor is how many products you need to package per minute.
| Daily Output | Recommended Machine | Speed |
|---|---|---|
| Under 5,000 units | ZF-A6345 L-Type Sealer | 40 bags/min |
| 5,000-15,000 units | ZF-A7050 / A9076 L-Type Sealer | 40-45 bags/min |
| 15,000-30,000 units | ZF-BF500-C Reciprocating Sealer | 60 packs/min |
| 30,000+ units | ZF-GS500-Z Reciprocating Sealer | 80-120 packs/min |
Choose Your Machine Type
L-type and reciprocating sealers serve different applications. Here's how to decide.
L-Type Sealer (ZF-A Series)
Vertical sealing design with strong, beautiful seal lines.
- Best for: Boxed products, multi-packs
- Speed: 40-45 bags/min
- Industries: Food, pharma, cosmetics
- Seal: Vertical, strong and clean
Reciprocating Sealer (ZF-GS Series)
Horizontal sealing for ultra-high speed flat product packaging.
- Best for: Cards, books, flat products
- Speed: 80-120 packs/min
- Industries: Publishing, toys, electronics
- Seal: Horizontal, high-speed
Choose Your Shrink Film Type
The film type affects seal quality, food safety, and appearance.
| Film Type | Best For | Key Properties |
|---|---|---|
| POF (Polyolefin) | Food, pharma, cosmetics | Non-toxic, odorless, crystal-clear, food-grade |
| PVC | Books, cards, toys | Cost-effective, good shrink ratio, strong seal |
| PE | Heavy products, bundles | Durable, tear-resistant, good for multi-packs |
Consider Your Complete Production Line
A single machine is just the beginning. Most clients need a complete line.
The sealing machine is your core choice. The shrink tunnel (ZF-S series) is required for all machines except the fresh flower packaging machine. Additional stations — case erectors, labeling machines, strapping machines, and palletizing robots — can be added based on your automation level needs.
