Endless liner
Description
The endless liner is a replaceable, single-use containment film from HECHT that acts as a barrier between the product and process equipment in closed bulk handling systems, playing an integral role in filling stations, isolators and sampling systems for the pharmaceutical, chemical and food industries. The liner is available shirred (fully extended, optimum volume) or folded (compact, up to 50% less storage space and cost), with quick switching between the two depending on container size and cost management. The system achieves containment level OEB 5 (less than 0.1 µg/m³ airborne dust) thanks to its closed design and production in cleanroom class D, and integrates with SAS connections, SBK filling heads, single-use isolators (drum/EWI) and HECHT samplers (CPP, CPS, screw) for a complete containment chain without external systems. Standard films (LDPE, green grid print) are available with no minimum order quantity, and existing systems from other manufacturers with CLS liners or tube packs can also be equipped with HECHT film technology.

Frequently asked questions about the endless liner
What is an endless liner and what is it used for?
An endless liner (continuous film) is a replaceable, single-use containment film used in closed bulk processing systems. It acts as a barrier between the product and process equipment in OEB 5 high-containment applications. An integral part of filling stations, isolators and sampling systems in pharmaceutical and chemical manufacturing.
What does OEB 5 mean and why is it important?
OEB 5 = maximum exposure limitation (<0.1 µg/m³ airborne dust). Essential for HPAPI and critical chemical processing where operator and product safety is absolute. HECHT endless liners achieve OEB 5 through closed design and cleanroom class D production.
How does a shirred endless liner differ from a folded one?
Shirred liner = fully extended, optimum volume. Folded liner = compact, up to 50% less storage space/cost. HECHT offers quick switching between the two — the choice depends on container size and cost-management requirements.
Which HECHT systems does the endless liner integrate with?
SAS connection, SBK filling heads, single-use isolators (drum/EWI), sampling equipment (CPP, CPS, screw, etc.), filling stations. Modular design — build complete containment chains without external systems.
Can I get endless liners custom-made for my container?
Yes, fully. Custom size engineering available. Send your container dimensions and interface specifications to sales — HECHT designs the right liner and SAS/SBK coupling.
Are endless liners GMP and FDA-compliant?
Yes. Cleanroom class D production, chemical-standards compliant, GMP Annex 1 compatible. Complete validation package (IQ/OQ/PQ per GAMP 5) available for GMP dossiers.
What is the advantage of single-use endless liners over reusable ones?
Single-use eliminates CIP/SIP validation, cross-contamination risk and maintenance costs. Sterile design guarantees closed handling. Waste is safely disposed of within the containment system per protocol.
Can I equip existing (non-HECHT) systems with HECHT endless liners?
Yes. HECHT offers retrofit solutions for CLS liners and existing tube packs. Engineering determines the correct adapter interfaces for seamless integration.
