PE film packing machine
Product Value
01
Replaces cardboard boxes with PE film, significantly reducing material costs for secondary packaging.
02
Automated collation and wrapping; compatible with high-speed downstream filling lines.
03
Dust-proof, moisture-proof, and load-stabilizing; offers clear visibility of the product.
04
Flexible collation capabilities supporting various pack configurations.
Applicability boundaries
Products
Multipacking rigid PET bottles or beverage cans
Packaging Materials
PE shrink film
Application
high-volume, end-of-line beverage bundling; alternative to cardboard cartons.
Working Principle
Bottle conveying and grouping → PE film unwinding and wrapping → Sealing and cutting → Hot air shrinking tunnel heating → PE film shrinks to tightly bundle the group of bottles/cans → Cooling and setting.
Core components
PE film unwinding system with constant tension mechanism
Bottle grouping and spacing mechanism;conveyor chain/belt
handles automatic bottle alignment, fixed-interval grouping, and tip-over prevention
Sealing and cutting assembly with Teflon-coated sealing blade
performs sealing and cutting operations
Photoelectric detection system; PLC + HMI control
Optional
01
Electrostatic elimination device for film; color mark registration for printed PE film
02
Automatic waste film take-up unit to maintain a tidy workshop
03
Quick-change tooling and multi-specification grouping stops
Changeover/Cleaning/Maintenance
Changeover
Ensure safety via lockout/tagout; replace grouping blocks, guide rails, and bottle-hold-down mechanisms; load the recipe via the HMI and adjust settings such as pack count, film length, seal/cut delay, oven temperature, and conveyor speed; perform a test run to adjust package centering, verify the absence of torn film or loose packaging, and save the parameters.
Cleaning
Daily: Clean accumulated film residue and carbon deposits from sealing blades, as well as debris from conveyor chains. Per shift: Remove accumulated film scraps and dust from the shrink tunnel. Regularly blow out air-cooling filters. Prohibit direct high-pressure water spraying on electrical cabinets, photoelectric sensors, and heating components; use a specialized high-temperature-resistant scraper to remove burnt residue from sealing blades.
What is the cost difference between PE film bundling and cardboard cartons?
For high-volume operations, the material cost of PE film bundling is significantly lower than that of cartons; however, it offers less impact resistance, making it best suited for short-distance transit and retail sales of multi-packs.
What causes loose bundling, poor film shrinkage, or film tearing?
Check the following first: ① Insufficient or uneven oven temperature/airflow; ② Improper film tension; ③ Abnormal sealing blade temperature or burrs on the cut edge; ④ Unstable bottle grouping or toppled bottles.
What are the standard production capacity and grouping configurations?
Customizable output of 8–35 packs/minute; common configurations include 2×3, 3×4, and 4×6, with layouts customizable to client requirements.
Can the system handle integrated bundling with a cardboard base tray?
Yes; an optional automatic tray feeding mechanism allows for integrated wrapping of the tray and PE film, making it suitable for aluminum cans and heavy bottles.
