Laminar Flow and Containment Equipment
Continuous Liner Discharge System
A long folded film liner mounted on a discharge canister so multiple contained bags can be filled, closed and removed without exposing the outlet.
- Long Continuous Film Sleeve
- Multi-Groove Canister
- Repeated Tie-Off Discharge
- Contained Bag Removal
Product Introduction
The continuous liner system fits beneath an isolator, dust collector, hopper or other discharge point. A long tubular film sleeve is folded onto a grooved stainless canister. Product or waste fills the extended lower section, which is closed with crimps or ties and cut between closures. The remaining liner is then pulled down to form the next bag while the outlet stays covered. Canister diameter, film material and liner length are selected for the product, load and disposal method.
Key Features
Multiple canister grooves secure the active liner and retained bag stub.
Crimp or tie-off tools create two closures before the filled section is cut away.
The liner can attach to rigid isolators, flexible enclosures or dust hoppers.
Different film formulations support antistatic, strength or compatibility needs.
Customer Product Concerns
Each filled bag must be removed without leaving the process outlet or contaminated bag stub exposed to the operator.
Removing one bag exposes the hopper outlet.The continuous sleeve remains over the canister while the filled lower section is cut away.
A single closure can open after cutting.Two crimps or ties create separated closed ends before division.
Film slides from the outlet under load.A multi-groove canister and retaining bands secure the folded liner.
One liner material is unsuitable for every powder.Film chemistry, thickness and antistatic properties are selected for the actual use.
Typical Applications
Powder waste dischargeTablet or component offloadingIsolator bag-outDust-collector hopper emptying
