Frequently Asked Questions
Common questions about the ZF-S450.
How much energy does an energy-saving shrink tunnel save? +
Actual power consumption depends on tunnel size, set temperature, conveyor speed, production load, film and product. Request measured operating data for the proposed model and test condition.
Which sealing machines pair with a shrink tunnel? +
Shrink tunnels pair with all types of sealing machines — L bar sealers, reciprocating sealers, and tire packaging systems. A shrink tunnel is a universal complement in any packaging line.
What is the temperature control accuracy? +
Automatic temperature control within ±1°C ensures consistent shrink results across all product types and film materials.
What warranty is provided on key components? +
Main electrical heating pipes and fan motors are guaranteed for 10 years — industry-leading coverage that reflects our confidence in component quality.
What are the available shrink tunnel sizes? +
Four models available: 450mm, 550mm, 650mm, and 800mm tunnel widths. Power ranges from 9.6KW to 23KW at 380V/50HZ. Choose based on your product size and production volume.
Which industries use heat shrink tunnels? +
Shrink tunnels are essential for food & beverage, pharmaceuticals, cosmetics, electronics, and tire manufacturing. Any product requiring tight, professional shrink film wrapping needs a tunnel.
What are the key features of an energy-saving shrink tunnel? +
The insulated chamber uses adjustable temperature, airflow direction and conveyor speed. Warranty terms and measured operating data are confirmed for the ordered model in the quotation.
Is a shrink tunnel a standalone machine? +
No. A shrink tunnel is supporting equipment that pairs with a sealing machine (L bar sealer or reciprocating sealer) to complete the shrink wrapping process.
