55-Gallon (200L) & 20L Rigid Drum Liners & Form-Fit Drum Inserts
Precision vacuum-thermoformed seamless HDPE/LDPE drum inserts engineered for open-head steel drums and pails. Built for high-viscosity pumps, pneumatic follower plates, high-shear mixing, and zero drum cleaning cost.
Why Leading Chemical, Coating & Adhesive Plants Switch to Lucheng Rigid Inserts
Standard thin poly bags wrinkle, trap expensive resin in pleats, and get shredded by high-shear agitator blades or pneumatic follower plates. Our self-supporting rigid inserts solve all three failure modes.
1. Straight-Sided & Tapered Rigid Liners (10L–200L)
Seamless vacuum-formed LDPE, HDPE, or PP inserts with a reinforced snap-over top flange that locks onto standard open-head steel or fiber drums.
- Standard Volumes: 10L, 15L, 20L, 25L, 50L, 200L (55 Gal)
- Wall Thickness: 15–40 Mil (0.38mm – 1.0mm)
- Top Rim Design: Contoured Crimp-Friendly Lip
- Pump Compatibility: Follower Plate & Piston Pumps
2. ESD Anti-Static & Conductive Rigid Pail/Drum Liners
Specifically formulated for solvent-borne coatings, automotive refinish paints, and ATEX Zone 1/2 hazardous environments (PPG Korea / APAC approved).
- Conductive Black: 10³ – 10⁵ Ω/sq (Zero Carbon Sloughing)
- Anti-Static Pink/Blue: 10⁶ – 10⁹ Ω/sq (Permanent Non-Amine)
- Compliance: ATEX 99/92/EC, TRGS 727, SGS IEC
- Solvent Resistance: 72h Xylene / MEK / Toluene Immersion
3. 3D Form-Fit Round-Bottom Liners (Space-Saving Alternative)
When sea-freight volume is your primary constraint, our 4–10 Mil (100–250 micron) 3D cylindrical round-bottom liners eliminate dog-ear corner waste while shipping flat in cartons.
- Film Gauge: 4 Mil – 10 Mil (100 – 250 μm)
- Structure: LDPE / LLDPE / EVOH / PA Barrier
- Seam Strength: > 25 MPa Dual-Impulse Thermal Seal
- 40’HQ Loading: Up to 65,000+ pcs per container
💡 How We Solve the #1 Weakness of Rigid Drum Liners: Ocean Freight Cost Optimization
The Industry Pain Point: Every experienced buyer knows that 200L rigid drum liners are “air cargo” (volumetric/bubble cargo)—a 40’HQ container maxes out on volume long before reaching its 26-ton weight limit, driving up per-unit ocean freight costs.
Lucheng’s 3-Part Engineering Solution:
- Precision Tapered Nesting: Our nestable 200L & 20L molds use an optimized draft angle with anti-jamming air-release ribs, packing 25%–30% more liners per stack without vacuum-locking during manual or robotic de-nesting.
- Heavy + Bulky Combo Container Loading (Zero Extra Volume Freight): Because Lucheng also manufactures heavy-density roll stock (anti-static films, flexible round-bottom liners, and heavy-duty PE zipper bags), we load high-density carton/roll goods at the base or center of the container alongside nested rigid liners—cutting effective per-liner shipping cost by 35% to 50%.
- Hybrid Rigid + 3D Round-Bottom Supply: Use 18 Mil rigid inserts for follower-plate/high-shear lines, and co-load 6 Mil 3D round-bottom form-fit liners for standard gravity-pour drums in the same shipment.

Frequently Asked Questions About Rigid Drum Liners
How does Lucheng solve the high ocean freight cost of bulky nested rigid drum liners?
Rigid drum liners are volumetric cargo (lightweight but bulky). Lucheng reduces landed ocean freight costs by 35% to 50% through two engineering methods: (1) High-precision 5-degree tapered nesting geometry that increases 40’HQ container loading by 28%, and (2) Factory-direct Combo Loading (Dead-Weight + Volumetric Pairing), where we co-load heavy rolls of anti-static film, flat PE bags, or industrial ziplock bags into the same container to utilize unused weight capacity without extra container volume fees.
Can your 55-gallon rigid drum liners withstand pneumatic follower plates and high-shear mixers?
Yes. Unlike thin blown bags that get sucked into mixer blades or tear under follower-plate wiping pressure, Lucheng’s 15–30 Mil (0.38–0.75mm) vacuum-thermoformed HDPE/LDPE rigid inserts feature smooth, self-supporting straight or slightly tapered walls and a precision-molded top lip that locks securely onto open-head steel drum chimes. This enables up to 99.5% viscous product recovery for adhesives, silicones, inks, and coatings.
How do Lucheng rigid drum liners compare to ULINE S-11858 / S-13792 and CDF drum inserts?
Lucheng manufactures to the exact dimensional and top-lip thickness benchmarks of North American and European standards (including ULINE S-11858 55-gallon 15–18 Mil straight-sided and nestable liners) using 100% virgin ExxonMobil/Sinopec resin in an ISO 9001 & Class 100,000 cleanroom facility—delivering 25% to 40% direct factory cost savings.
Do you offer custom mold tooling for non-standard steel or fiber drums?
Yes. With in-house CNC mold machining, we customize top rim diameter (e.g., 570mm–615mm), depth (up to 910mm), and wall thickness within 10–14 days. Tooling fees are 100% waived or refunded on standard container or annual blanket orders.
