400m≤Plastic Seal＜700mm

Usage Scenarios and Industries Application for 400mm-700mm Extra-Long Plastic Seals:

Why Length Matters: Standard plastic seals can’t reach around thick, rolled fabric closures.
Where need long length plastic seals?
1. Bulk Bag & FIBC (Flexible Intermediate Bulk Container) Security
Rolled-Top FIBC Bags: Seals require 500mm+ length to:
Wrap around rolled/folded bag spouts(common in food, chemicals, pharmaceuticals).
Secure double-layered closures for moisture-sensitive materials.
Super Sack Transport: Prevents tampering during rail/shipment of: Plastic resins | Agricultural grains | Industrial powders

2. Heavy Machinery & Industrial Equipment
Construction/Agriculture:
Plastic seals excavator fuel tanks (400mm+ to loop around large filler necks)
Locks tractor ECU compartments from theft.
Mining: Secures explosive storage containers with multi-point sealing.
Key Advantage: Withstands vibration and outdoor UV exposure.

3. Oversized Logistics & Special Transport
Wind Turbine Components: Seals 600mm+ blade/gear crates during ocean freight.
Aerospace: Locks aircraft engine shipping frames (FOD prevention).
Military: Tamper-proofing for missile canisters or radar equipment.
Critical Need: Extra length covers custom latching systems on atypical cargo.

4. Utility & Energy Infrastructure
Power Grids:
Plasitc seals transformer access panels (500mm to loop through grounding rods).
Protects substation circuit breakers.

5. Oil/Gas:
Plastic seal locks flange connections on pipelines.
Secures drilling mud storage tanks.
Regulatory Fit: Often required for ISO 17712 “S” Security compliance.
