LK® BCT4-48 – 48″ × 500 ft Class 100 Clean Room Tubing | 4 Mil | 1 Roll/CS

LK® BCT4-48 – 48″ × 500 ft Class 100 Clean Room Tubing | 4 Mil | 1 Roll/CS

The LK® BCT4-48 is a 48″-wide, 500-foot roll of 4 mil Class 100 clean room tubing manufactured in a certified ISO Class 5 (Class 100) clean room. Produced from barefoot virgin polyethylene resin meeting FDA standards, the tubing is wound on a heavy-duty plastic core and double-bagged upon packaging to preserve clean room integrity through delivery. Each case contains one 500-foot roll — the widest format in the LK® clean room tubing line, designed for large-scale component and assembly packaging in demanding clean manufacturing environments.

What industries and large-format applications use 48″ Class 100 clean room tubing?

At 48″ flat width, BCT4-48 tubing opens to roughly 15″ in diameter, accommodating very large components and full sub-assembly packaging: turbine blade sets, large optical telescope assemblies, full wafer-carrier stacks, wide flat panel display units, medical imaging system components, satellite sub-arrays, and large robotic or automation modules. Aerospace prime contractors, semiconductor equipment manufacturers, medical imaging OEMs, and defense systems integrators use this format for clean room packaging that no standard pre-formed bag can accommodate.

4 Mil Polyethylene Film: Large-Format Strength for Heavy Clean Room Components

The 4 mil wall in BCT4-48 balances structural rigidity with sealing compliance across the full 48″ width — a non-trivial requirement, as wider tubing demands consistent gauge uniformity to avoid seal failures at the edges. Produced from barefoot virgin PE with no additives, slip agents, or recycled content, BCT4-48 film meets the outgassing and cleanliness standards of Class 100 environments, protecting optically sensitive, chemically reactive, or electrostatically fragile large components from surface contamination.

Full Sub-Assembly Sleeving for Aerospace and Defense Clean Room Operations

Aerospace and defense clean room operations routinely face a packaging gap when dealing with large-format subassemblies: no standard pre-formed bag exists for a 14″-diameter turbine shaft housing or a 40″-wide satellite panel bracket. BCT4-48 roll tubing fills this gap with on-demand sizing — operators cut the exact sleeve length, fold or heat-seal one end around the part, and seal the other to create a clean room-certified custom bag. This eliminates the need to special-order custom-sized bags and keeps packaging operations agile in low-volume, high-mix clean room environments.
